up our real time doppler radar. the entire bay area getting hit with a wet storm. it's a welcome spring storm. >> let's open up our windows, live looks from the north bay. we drive through san rafael down to the south bay. we find not just rain but wind, thunder, maybe even a little snow on our bay area peaks. >> good morning on this tuesday. thank you for joining us. i'm sam brock. i'm kris sanchez. our "today in the bay" team is here to bring you what you need to know before you head out the door this morning. we'll start things off with meteorologist christina loren. set the scene for us. we see lots of colors on your radar. >> more like april downpours than april showers this morning. what you will notice is a lot of the heavy activity is over your inland valley spots. we're getting a little break from the yellow and red at the immediate coast but take a look at some of our totals so far. very impressive numbers. lake sonoma, under an inch and a

half. fremont picked up over 0.86, same for saratoga and berkeley on the way to half an inch of rain. with more on the way, the heavy stuff is going to continue to come through. between now and i'd say the 8 a.m. hour at this point because the system is slowing down. in addition to the fierce wind we have out there, you have the rain coming in. the two elements combined are creating kind of dangerous conditions out there. which is why we want to send it over to anthony slaughter. he's been tracking a traffic alert involving a jack-knifed big rig. >> all lanes are closed within the last half hour. the big rig jack-knifed at north mission boulevard and they have closed the entire freeway this morning. no lanes are getting through at

north mission boulevard. as we pitch is to the maps, want to show you where this is in proximity to the rest of the bay. that's where it's stop and go. that's where you can hop over on 880 or do mission boulevard. slow coming in on 680 southbound because folks want to see what's happening. slow going northbound. that highway is closed 680 at north mission boulevard. no lanes getting through for the next half hour. >> thank you very much. major problems in fremont to san jose. getting into the south bay is challenging, especially if your commute takes you over highway 17. >> let's get another vantage point. bob redell joining us from the summit where the rain has been coming in all morning long. good morning, bob. >> reporter: yes. good morning to you. we've seen it come in heavy, come in light, but it has been steady. right now we're getting a little lull, i would say.

you can see the headlights heading northbound from los gatos into sane ththe santa cla valley. you can see how wet the roads are. chp reminds you, you want to watch your speeds out there. you want to watch the distance between you and the drivers in front of you. you do not want to be tailgating in these wet weather conditions. keep in mind, it's been a few months since we've had a good rain. the roads could be a little extra oily this morning as that oil that's been setting for the last couple of months starts to percolate to the surface and make the roadways even more slick. there you have it, as you can see drivers getting into work this morning. if you have the opportunity to work from home, this might be one of those days to do that. it is noticeably chillier. reporting live on the summit, bob redell, "today in the bay."

>> thank you very much. let's take a live look at foster city side of the san mateo bridge where, as we've been talking about all morning long, a wind advisory is in effect. take it slow. give yourself extra time as you leave the house and keep both hands on the steering wheel. >> that wind an issue for bridges. "today in the bay's" stephanie chuang joining us from the san mateo bridge. >> reporter: the rain is coming down steadily but the wind changed directions. you can imagine how that's tough for drivers on the road. what's also different, you take a look at san mateo bridge, more headlights, which means more risk for collisions. the chp issued a wind advisory for that bridge as well as richmond-san rafael, san mateo and dumbarton. just getting onto 101 where the water was pooling on the far

right lane. creating big splashes as well as impairing your vision and the rain getting kicked up by neighboring vehicle. watch out for those problem spots with storm drains getting clogged and caltrans is trying to get out there and clear those drains. the advice we've heard, slow down and leave plenty of space between your vehicle and the next one. live in foster city, stephanie chuang, "today in the bay." >> from the ground level, thank you very much. we'll be tracking the storm all day long. you can also track the rain yourself from your smartphone in the comfort of your inside. download our nbc bay area app. new this morning, it appears weather was not the cause of this deadly and fiery crash that shut down all northbound lanes of 101 in the south bay overnight. this is what's left of one of the cars involved. the chp says a witness saw a pickup truck hit that car while it was on the freeway. the stalled car then caught fire

and the person who was inside was trapped and died inside that car. that fire burned for more than an hour. this happened after midnight in san jose north of the airport. the cause of that crash is still under investigation. the attack, vicious. now the man accused of attacking a homeless man in san francisco last week will be in court later today. police believe arthur lee jones is the man seen in this security video swinging a metal pipe or a bat at a homeless man. that blow left the man with severe head injuries. witnesses told police the two got into an argument earlier and jones later returned to attack the man. and the search is on for this man who police say jumped over a pharmacy counter and robbed a walgreens drugstore employee at gunpoint. the surveillance video shows the man getting away with about 20 bottles of prescription drugs. retired san jose police

officer is recovering from a stab wound he suffered this is weekend at a high school. the man works as a school security officer. he tells the mercury news he and a partner broke up a group of men who were drinking and smoking at branham high. one of the men started to argue with the retired officer and then punched him and stabbed him in the back. police later arrested that suspect. we return now to your microclimate weather alert forecast as we give you a live look outside right now. the golden gate bridge. of course, it is south of the city we've really seen the heaviest rainfall this morning. christina, how much longer do we expect this to last? >> i think the main cold front will be out of here by 8 a.m. this morning. good morning to you. i want to show you an overall view of widened out so you can see the size of this storm, very impressive. and the core of low pressure is actually going to move over the bay area as we head throughout the day today. when that moves over, that's when we have that chance for a thunderstorm.

you see the bulk of the cold front starting to push east of the bay area. this is the actual core i'm talking about. this is going to come through later on today. we will be watching for some thunderstorms for you. what i love about this storm is that it's maintaining its organization and it has not yet reached south lake tahoe. by the time it does reach the sierra nevada, i think it will stay organized enough to potentially produce that 1 to 2 feet of snow we have been anticipating and we really need. that is the good news. we'll be keeping tabs on that for you this morning. want to zoom in and show you where the heaviest rainfall is located right now. you can see the storm is finally starting to push into the south bay and areas to the east. otherwise we're getting a little bit of a break at the coast up to the north bay where we have accumulated up to 1 1/2 of rain thus far and more on the way. wind will stay rather strong as we head throughout the day today. we're in the double digits just about everywhere.

10 to 20 miles an hour sustained gust up to 40 miles an hour gusts. we stop that clock at 9 a.m. getting heavy moisture on the east side of the bay area. that extends into the south bay. then i take you into the afternoon/evening hours between about 12:00 and 6:00. there is the core of low pressure. that's when we have that chance for thunderstorms. by 6:00 to 8:00, as you start to make your way home from work, things will really improve. looking toward a safer drive home. you really want to give yourself extra time this morning. it's downright dangerous out there. especially south of highway 92. want to check on that traffic alert right now, get the latest from our own anthony slaughter. >> 680 northbound connecter. a live picture from the scene right now and no lanes are getting through 680 northbound because they're trying to clear this big rig off the streets. you have to get around this.

use mission boulevard and hop over to 880. even if you try to hop back onto 680 at north mission, you can't do that either. use 880 as an alternate because it looks like it will be closed for the next half hour, possibly even longer. keep that in mind if you use 680. northbound side being affected. southbound is being affected as well because folks want to see what's happening on the northbound side. coming through the pass, typical slowing. we have an accident on 580 eastbound at san ramone. coming through the bay bridge maze. this is where we have a lot of accidents that continue to pop up because of the rain. they're small accidents, spinouts, fender-benders but creating a slower go than we typically find here because it's raining, you get the accidents and people are already going slow. really stop and go as you approach the maze. no big surprise, but the added rain, the added accidents making

this one of the places where you just want to avoid this morning. if you have the power to avoid it, hop over to the san rafael bridge, richmond bridge and go that way to get around it. >> we also tell people sometimes to hit the road early to give themselves extra time. maybe wait if you can. >> or leave now. >> might be too late. >> thank you very much, anthony. time now is 6:11. coming up, the next candidate tossing his hat into the 2016 presidential race. plus, good news for people trying to make ends meet on minimum wage. we'll take a look coming up. and good news from at&t park as the giants are not home to have to deal with the elements right now. they're off in sunny arizona winning. you see right there the effects of some of the winds on the water. we'll be tracking the latest storm conditions. christina very busy this morning.

mouch longer the heavy rain will last and when we could see thunderstorms roll over your neighborhood. that's in just moments. and other top stories we're following for you this morning. one person is dead after the chp says a pickup truck slammed into a stalled car on northbound 101 in san jose. that car caught fire and trapped the driver inside. jury deliberations just began in the boston bombing trial. closing arguments wrapped yesterday. now the defense tried to paint suspect dzhokhar tsarnaev as a follower to his brother's master terror plan. in just a few hours, kentucky senator rand paul is expected to announce his run for president. paul would become the second

republican contender to formally announce following texas senator ted cruz. >> rand paul once compared the republican party to domino's pizza. >> he didn't mean it. >> he did mean it as an inspiration. domino's came out recently and admitted its crust wasn't very good, so it made a change. paul says the republicans need to admit their image could use some improvement. domino's working on changes itself this morning. it plans to pay its workers more. the latest company to do so. we've seen the same from walmart and target and mcdonald's. starbucks says it's going to pay its employees' tuition for all four years of course work through arizona state's online classes. you can get a full four-year degree that way. starbucks says at least 144,000 employees qualify. as we give credit to all the companies jumping on these pay and benefits trains, let's mention jamba juice.

it's been routinely paying entry level workers more than minimum wage for years. they may have to increase its pay to catch up with the johnny-come-lately. a company that helps people manage their expense reports says nearly half of the rides taken on business trips were taken in ubers. the other half, obviously n taxi cabs. uber runs in more than 300 cities worldwide. some are banned in india to ceasing operations in san antonio, texas. what this map doesn't show is all the cities where things are going completely swimmingly for uber. back to that expense report report. what do you think is the most expense expensed, what store or chain? >> target? >> mcdonald's. >> starbucks. >> of course! >> you're on a business trip,

starbucks. >> because of the wi-fi. later today, state water leaders are going to discuss how to best keep communities in line with water reduction plans. the problem here, which they've encountered before, how to enforce the mandatory 25% water cuts issued by governor brown last week. especially for the largest water wasters. cities will likely receive conservation targets based on the amount of water residents that are already in use. more now on our microclimate weather alert as we take a look at our real-time doppler radar and also a live look outside at palo alto right now. you can see that storm is moving in. roadways very slick. with good morning to you. >> good morning to you. this cold front is almost all the way past the coastline and through the north bay but we're still seeing heavy downpours

working through the south bay and east bay. that goes for the tri-valley. you can see over the -- wherever you're headed this morning, travel cautiously. now i'm going to stop that radar for you. you can see where the heavy stuff is coming through. that's downtown san jose all the way south through watsonville this morning. please take it easy. what you will notice is we're done at least for the time being with the yellow and the red at the immediate coast in san francisco. just getting some light green, lighter showers. as i show you the north bay, also looking pretty good up here. areas to the north of the golden gate bridge for a little bit of a break that extends through marin and sonoma county. there is more on the way as the actual core of low pressure comes through later on today. what you'll notice associated with this core, you see that well-defined counterclockwise rotation, some spotty clouds surrounding it. that's an indication of a very cold air mass that's going to work its way into the bay area

as we head throughout the day today. so, the main cold front comes through. by 9 a.m. we get a little bit of a break. we continue that futurecast. you can see the core coming through. between 12:00 and 6:00. then after 6:00, 6:00 to 7:00 tonight, starting to see things improve. tomorrow morning we might see residual activity but a lot will be done at that point. good news is, we're still expecting 1 to 2 feet of snowfall up in tahoe. here's the thing for today. if we see any of these strong storms fire off, likely to be the case up in the north bay, the south bay, high elevations, also the east bay hills, we could actually get rain rates of maybe a half of an inch of rainfall per hour, which is really intense. so, we are keeping an eye on the opportunity for some pop-up daytime thunderstorms for today. we'll be here in the nbc bay area news room. if you hear the thunder, turn on your tv and we'll keep you updated if anything does get severe. getting into your wednesday and

thursday, dry trend. tomorrow by lunchtime, lots of sunshine out there. hopefully we'll be able to see a dusting of snow on top of mt. hamilton. it won't last long with temperatures rising into the mid-60s. tomorrow we're in the 70s by thursday. friday into saturday, a little bit unsettled out there with the jet stream just to our north. we still stand a 10% to 20% chance of showers getting into the weekend. we'll be keeping tabs on that for you as we continue on through the week together. right now i want to send it over to anthony slaughter. he's tracking that traffic alert and several other crashes so far this morning. please take it easy out is there. what's the latest, anthony? >> to say the least, take it easy, guys. we're actually talking about 680 northbound right at north mission boulevard. in the last five minutes they're starting to let cars through once again. one lane is open on 680 northbound but earlier around 4:42, that's when this actually happened, and it's been slow going since then. you'll also notice 680 southbound is slow because folks are trying to take a peek at

what's happening. let's switch to the map and you'll see what we can see on the maps perspective. there's the slowing. within the last five minutes, another accident happened. this thoroughfare one you want to avoid if you have the power to do so. 580 slow there. we have an accident on 580 eastbound in san ramone and also at the connecter, 680 on 580. lots of aaccident across the ea bay. another spot you want to avoid if you can, approaching the bay bridge toll mraz simpla. we've had numerous accidents on 80, westbound approaching the maze. we're starting to find a few accidents, 580, 980, every location you look at this morning. we're looking at a few axe deputies there. small accidents, fender-benders, spinouts but creating an even slower commute. in the city we've had reports of roadway flooding on 101. same deal for 80 westbound on the ninth street exit ramp and

daley city we've had reports of that as well. take it easy because the roads are wet and we're starting to see ponding as heaviest parts of the storm is moving through. we are starting to see a little break in san francisco so the drandz will have a little chance to soak up the rain we're seeing right now. back to you. >> that rain so critical. thank you very much, anthony. we'll be back with a look at how this storm is impacting the storm. looking live at san mateo bridge. one of the bridges where there's a wind advisory in effect. you want to be careful if you're heading over a bridge. we'll check in with stephanie chuang, who is on one of the bridges this morning for conditions.

we continue with our microclimate weather alert. want to look live out from san bruno mountain camera. you can see the clouds shrouding the city by the bay, but the rain is continuing to fall and we have impressive totals coming up with christina loren in a few minutes. >> the rain here means snow in the sierra and it's already coming down today. >> "today in the bay" with a look. >> reporter: good morning from donner summit where the snow started coming down around 4:30, just snow showers. getting ready for significant snow in the sierra. probably one of the most powerful storms of the season as resorts are getting ready for as

much as 2 feet of snow in highest elevations and pass level could see a foot or more of snow. that means for drivers coming into the sierra, get ready for winter driving conditions. you will need those chains, you will need a four-wheel drive with good snow tires if you're traveling into the mountains today as the forecast is expected to deteriorate through the morning hours and into the afternoon here in the sierra. certainly great news for the drought as we need any moisture we can get up here. that snow, again, totaling as much as 2 feet over the highest elevations of the resort. unfortunately, a lot of the resorts have pulled the plug on the season. for those that are open, could be a great powder day today and tomorrow adding to the money they desperately need this time of year as they start to wind down their season. if you are coming up here to the mountains, dress for the cold and be ready for the cold on the highway. brian hickey, "today in the bay." >> amazing to hear him say one of the biggest storms of the season, so late in the season. >> but so needed. 6:26 right now.

i am an electric crew foreman out of the cupertino service center. i was born and raised in the cupertino area. it's a fantastic area to work. the new technology that we are installing out in the field is important for the customers because system reliability i believe is number one. pg&e is always trying to plan for the future and we are always trying to build something stronger and bigger and more reliable. i love living here and i love the community i serve. nobody wants to be without power. i don't want my family to be without power. it's much more personal to me for that reason. i don't think there's any place i really would rather be. pop-up thunderstorms. we'll have all the latest.

this morning we're finding numerous spinouts and accidents. northbound 680 has a sig alert. we did much better on the markets than we expected. they'll try to do it again today as business gets under way. live look outside this morning. the city by the bay. some clouds and certainly plenty of rain still coming down. today's tuesday, april 7th and you're watching "today in the bay." good morning. thanks for joining us. i'm kris sanchez. >> i'm sam brock on a rainy tuesday. we begin with an nbc bay area microclimate alert. it is wet but welcome. right now a look at our real-time doppler radar where you can see the heaviest rain falling through the south bay and in santa cruz right now. all different colors out there on the radar. now let's take you outside with

live looks at the golden gate bridge and downtown san jose. raindrops blurring our camera lens a little bit all over the bay area. meteorologist christina loren will tell us when the rain will clear and anthony slaughter will have a look at the impact to your morning drive. first happening today, a big announcement from rand paul. he's expected to become the second gop to officially -- or gop candidate to officially enter the presidential race. tracie potts joins us from washington, d.c. to tell us what this means for the race. good morning. >> reporter: it means it's getting a little more crowded, sam. not too crowded yet. he is the second candidate mainstream republican candidate to jump in. that mainstream title is up in the air because he doesn't yet have the support of the republican base. libertarian base, yes. it's something he and his father, ron paul, built when ron paul ran for president three times. but now he's got to expand that a bit. he's bringing in young people. he's talking about minorities

and minority issues, bringing in some minority voters, but he has to expand that base. republicans, establishment, still concerned about some of his positions on foreign policy. he'll get a chance to explain all of that in a few hours when he makes that official announcement. then he's hitting the road from the announcement in kentucky to new hampshire and iowa and south carolina and nevada. the first few states where he's going to campaign all early primary and caucus states. >> things just starting to heat up. tracie potts from washington, thank you very much. u.s. senator john mccain says he will run for re-election again. the arizona senator will seek his sixth term in 2016. mccain will be 80 years old by election day but tells nbc news his senate career is just beginning. mccain is the chairman of the senate armed services committee. we return now to our top story this morning as we watch a

microclimate weather alert and give you a live look outside at&t park. you can see the droplets on our camera. plenty more where that came from. >> indeed. and we know we have gotten some impressivele totals so far. christina loren is watching what's falling and already has fallen. >> happy to see so much rainfall coming through over just about a 12-hour period so far. look at this. over an inch from mill valley, high ward, pacifica, under an inch in fremont. the big winner when it comes to accumulations, up in lake sonoma, an inch and a half of rain and there's more on the way as we head throughout the day today. steady rainfall, the heavy rainfall associated with the main front is starting to push out of the area. we're still dealing with some heavy downpours all the way from san jose through morgan hill. prees travel cautiously this morning. what you will notice about your

real-time doppler radar is showers are starting to let up extending up through san francisco and sonoma county. we do have more on the way as we get the main area of low pressure later today. that could also kick up some thunderstorms as we head throughout the second half of your day. we're counting on that mostly between about 12:00 and 6 p.m. we'll be here watching that for you in the nbc bay area weather center. what you'll notice over the past three hours is, a lot of rainfall has moved over the greater bay area, so even though it's not raining right now outside your do, likely still to encounter slick conditions out there. we have a chance of pop-up thunderstorms and that gusty wind will continue throughout the day. so, we're not done with the storm just yet. i'll time it out to your door step coming up in my next report. you know, anthony's already working with a series of accidents this morning. let's get over to him and that report. >> good morning to you, christina. as you were mentioning, we had a sig alert issued on 680 northbound. this is a live image from that

accident, jackknifed big rig. they're only letting one lane through on the shoulder. it's been closed for 30 minutes. starting to let those lanes through. 680 southbound is slow because folks are taking a peek. both sides of the highway slow going. let's switch to the map. the blue denotes there's hydroplaning possible on the roads possible. lanes on the highway indicates stop and go traffic. in the last 15 minutes there was an accident on 680 so this is one of those places you just have to stay away from this morning. it continues to remain slow through pleasanton on 84. things are slow through dublin and approaching the maze is where it's been stop and go. 980, a slew of accidents there and 80 westbound. it seems like every five minutes another accident just pops up here. this is one of those places you want to avoid if you can, drive

slow if you can, and watch out for folks. even coming through this morning, even though there were few cars on the roads, folks were driving 60 or 70 miles an hour. i was going about 40. >> those maps you're seeing, that blue is hydroplane danger. that blue has been on every one of your maps. >> all across the bay. >> just block off more time today because it's going to take you a little longer. 6:36. the markets have been open for six minutes. >> let's check the numbers with scott. good news in those six minutes? >> yes, good news. we've had a pretty good day yesterday. in fact, an unexpectedly good day yesterday. considering the lousy jobs news. once again, we're at least moving to the positive today. dow industrials up about 60 points. well, you know, an ipo, this is the opposite. redwood city informatica went private, when investors buy up stock from every shareholder, take the company out of the stock market. they had to pay more than $5

billion to do it. business as usual as informatica for every employee today but they have new owners this morning. not shareholders. back to you. >> change of course. thank you very much, scott. it is 6:36 right now. still ahead, an alarming new study, shining light on the cost of breast cancer. live picture outside. we've been following the storm this morning as we see the rainfall continue to come down, especially near the santa cruz area, off highway 17, what you're looking at right now, and in the south bay, too. christina will get you up to date on exactly how much longer this is going to last and how those rain totals and snowpack totals look.

jury deliberations began less than an hour ago in the boston marathon bombing trial. both sides presented closing arguments yesterday. defense attorneys did not dispute dzhokhar tsarnaev's

involvement but they did try to argue he was heavily influenced by his older brother who they argued mastermind the terror attack. . for more than 50 years the coast gard has been leasing space at l.a.x. but now the airport is planning an expansion product forcing the coast guard to find a new station. they won't have to move out until september of 2016 but it has not chosen a new location yet. says there will not be be any interruption to service. a possible data breach. some 8,000 california college students and applicants may have had their personal information stolen. officials from uc-riverside say someone stole a desktop computer from the graduate division offices and it happened nearly a month ago. the computer contained information on grad students and graduate school applicants. campus officials say it took them a long time to figure out just who was impacted.

an alarming new study for women this morning. false-positive mammograms cost the nation $4 billion a year. false-positives suggest a woman has breast cancer when she actually does not. the authors of the study say costs are so high, screening may be cost ineffective. the american cancer society recommends annual screening for women beginning at age of 40. the u.s. preventive services task force calls for screening every two years in women aged 50 to 74. 6:41 right now. it's been a busy morning. coming up next, wet weather causing all sorts of problems across the bay area, including this. a jackknifed big rig blocking 680 northbound in fremont. it's just one of many things drivers are dealing with this morning. and one of the issues drivers are also dealing with this morning, the wind and we are looking live although san mateo bridge where those drivers are likely holding on very tight with both hands. we're back with 15 minutes of nonstop news, traffic and

weather right after the break.

and right now we start you with that microclimate weather alert we've been observing all morning long. all sorts of colors lighting up the doppler. the heaviest rain falling south and southeast of san jose. live looks across the bay area this morning. as we take a look outside from san rafael to san bruno, bay

bridge and san jose as well. driving very treacherous this morning. multiple reports coming up this morning. we begin with bob redell live at the summit of highway 17 where the rain has been coming down basically in sheets all morning long, bob, but you were finally able to take down your hood. >> reporter: good morning to you, kris. coming down but not as much as it was about 45 minutes ago. the roads are still wet because rain has been coming down for a good few hours now. while most people were asleep overnight and certainly continuing on. you see the headlights, heading northbound on highway 17 in the commute direction across the santa cruz summit in santa cruz mountains into los gatos and san jose. as any chp officer would tell you, even if the speed limit is posted at 65 miles an hour, they prefer you drive whatever you feel is the safest limit, if that's 60 or 55 because they obviously do not want to have

any accidents. there have been a few throughout the bay area this morning. most notably the one anthony has been talking about at sunol which he'll update you on moments from now. chp would advise you to watch your speeds, don't tailgate, watch the distance between you and the driver in front of you. keep in mind, this is the first big rain we've had in a few months. over the past few months the oils and other fluid on the road are sitting there and now that the rain is coming up, it will make the roads a little more slippery than they would be if it was just regular rain. you'll have the combination of water and oil out there. you definitely want to be careful out there. if you can work from home, if you have that luxury, this might be the day to do that. reporting live here atop summit of santa cruz mountains along highway 17, bob redell, "today in the bay." a lot of ponding out there on the roadways as the rain totals starting to accumulate this morning. we take a live look outside right now at the bay bridge. san francisco bay area saw some rain but a lot of that really

farther south now, christina. we're seeing rich means heavier rainfall. >> that is heavy pockets of rain. right now centrally located over morgan hill north to san jose. that's where i wanted to start this morning. we'll move you up the east shore and show you what's taking place there. this is where the rain is the heaviest this morning. you can see all the way from san jose through fremont, still getting some pretty good rainfall. a lot is working its way into the tri-valley. i take you even further to the north and what you'll notice is we're still getting heavy pockets from san ramone through concord, antioch and even discovery bay. as i show you the coast, this is where we're starting to get a little break with light precipitation rolling through. we have more on the way, though. this is the main front coming through. by 8 closhg this morning, a lot of that activity will be out of the bay area. but had is the area i'm watching. here you go.

you have this main line, the main cold front. you see these spotty clouds and counterclockwise rotation, that's the actual core of low pressure associated with this storm system. it will cross over the bay area. it is packing a great deal of instability so the chance to get pop-up thunderstorms is likely this afternoon. by 9 a.m. as the main rush starts to wind down, that's when things will start to wind down when it comes to that main cold front, pushing toward tahoe, staying organized, which is why we're counting on the 1 to 2 feet of snowfall above 4,000 feet, which is a very low snow level. we have not seen that yet this season. i can tell you definitely a welcome sight for those resorts still open including sqaw and alpine. we stand a really good chance for forms to develop as we head through 12:00 and 6 p.m.

rob and myself will both be manning the weather area for you today. we're not leaving until things start to wind down. i take you into the 7:00 hour. that's when we will start to see more tranquil conditions across the bay area. before all is said and done, we are expecting over 2 inches of rainfall in the north bay. when it comes to the thunderstorms, this is where we have the best chance. tuesday afternoon and evening, so between 12:00 and 6:00, like i said. that goes for the immediate coast. then in this order. high terrain areas of the north bay, the east bay and also the south bay. so, we'll be watching that for you online and, of course, right here on nbc bay area. if anything develops, we'll break into coverage and tell you about it. temperatures mostly in the upper 50s to low 60s. you'll need your jacket all day long. as we head throughout the remainder of the week, temperatures will be cool tomorrow. some residual activity then. then 70 by thursday. friday, 69 degrees.

for your saturday, 67 degrees with that jet stream just to our north. 10 to 20% chance for showers as a result saturday into sunday. we have something else to watch once this system is out of the area. right now, he is watching your drive very closely. let's get an update on that traffic alert, see if 680 has reopened. good morning to you, anthony. >> good morning. yes, 680 reopened. they were earlier letting cars through on the shoulder. every now and again, it seems as though they close, it reopen it and close it. with this shot, looks like it's closed again. again, this is just one of those spots you want to avoid. 680 northbound at north mission boulevard. that's where where things appear to be closed once again. they'll continue to work to get this big rig off. 680 southbound it's slow as well. as we switch over to the maps, you can actually see all the red, that means it's stop and go and even farther because of another accident at altamal

parkway. 680 southbound is slow working toward the accident once you get passed it, things start to speed up. let's take you down to the southbound because we're seeing big slowing on the 101. we have a couple accidents on 87 and 280. the overnight construction continuing to wrap up. i want to take you here on 101. you can see the slowing. there's an accident at 101 and the 87 connecter. as we take you outside, you can see what we're talking about. the cars are very slow going here because of not only the rain and the added traffic now, but because of those accidents we're starting to see again. the one right at 101 and 87 connecter there. it's slow going everywhere you go this morning. remember, pack that patience here on this tuesday. back over to you. >> thank you very much. as anthony told us, the wet weather is causing problems for the morning commute. >> "today in the bay's" stephanie chuang joining us from d a. -- daly city. >> reporter: good morning. we move now to daly city,

southbound 280. we're looking at the east off-ramp, a large pool of water and a car that is now stuck in the middle of that. the highway patrol here blocking this off-ramp. we also saw there is one person, it looks like he or she is stuck inside the car. also did see a caltrans truck a mile and a half ahead. maybe they're waiting to see if caltrans can come and get the water to drain here finally and then be able to tow this car away. we've seen this with past storms back in december in san francisco where chp continues to tell people, do not drive through this kind of a scenario, because can you get stuck. take a live look at the car in the middle of this off-ramp. the rain has actually let up here, but you're seeing the impacts of what was the storm moving through this area. so, that's the latest from here. again, there have been wind

advisories across the bay area for all the bridges. so, the scene we've continued to hear from chp and everyone else is give yourself plenty of time this morning. live in daly city, stephanie chuang, "today in the bay." >> the sump pumps will be in high demand. thanks very much. >> we'll follow the storm all morning long with live updates every half hour throughout the "today" show and during our 11 a.m. newscast. for the latest forecast at your fingertips, download our nbc bay area weather app. you can track the rain to your door step using our rereal-time doppler radar. it appears weather was not the cause of this deadly and fiery crash that shut down all northbound lanes of highway 101 in the south bay overnight. this is what's left of one of the cars involved. the chp says a witness saw a pickup truck hit that stalled car on the freeway. the stalled car caught fire, trapping and killing the person inside. the fire burned for more than an hour.

this happened just after midnight in san jose at exit 4 de la cruz boulevard. the cause of the crash is still under investigation but, again, the lanes are open. vicious violence. now the man accused of attacking a homeless man in san francisco last week is going to be in court later today. police believe arthur lee jones is the man seen in this security video swinging a metal pipe or a bat at a homeless man. that blow left the man with severe head injuries. witnesses told police the two got into an argument earlier in the day. jones later returned to attack the man. former 49er and raider will soon have his day in court. kwame harris is accused of driving under the influence of drugs, hit-and-run and resisting an officer. we have video of the incident that happened sunday night. police say he was careening through the streets of san francisco before he passed out in his car. when authorities caught up to him, the car was still running. when he came to, harris did not cooperate.

>> the suspect then tried to bite the officer's hand. thankfully the officer was not bitten. >> police did arrest harris. harris left football in 2008 and then hit a low point in 2013. this mug shot was from a domestic abuse arrest for beating up his then-boyfriend over an argument involving soy sauce. 6:55 right now. the search is on for this man who police say jumped over a pharmacy counter and robbed a walgreens drugstore employee at gunpoint. this happened last week at the walgreens on alamaney boulevard. surveillance video shows the man getting away with 20 bottles of prescription drugs. a retired san jose police officer recovering from a stab wound he suffered this weekend. the man works as a school security officer and he tells the mercury news, he and a partner broke up a group of men drinking and smoking at branham high school. one of the men started to argue with the retired officer and then punched and stabbed him in the back.

police later arrested the suspect. eight candidates for city council face off in special election to fill one open seat temporarily. today's election covers district 4. the candidates are vying for a partial term for the seat vacated by former council member who is now in the state assembly. one candidate will have to receive a majority of votes to win outright. if not, there will be a runoff in june. the san jose city council also talking today about extending the life of its family camp at yosemite. city staffers will recommend the city council negotiate with the u.s. forest service to extend the lease agreement. the current agreement expires at the end of this year. they just rebuilt the camp after the devastating rim fire. the fire charred hundreds of trees and destroyed more than a dozen cabins. students are cooking up a new battery. >> it is better than anything on the market, they say.

>> good morning to you. students released youtube video of their new aluminum battery this morning. they published their results in the journal "nature." biggest advantage over current lithium-ion battery is their battery doesn't catch fire. let's talk about star wars. they'll make history as it is released on friday in digital form. you've never been able to download star wars or empire strikes back or any of the other movies before. and it will hit itunes and amazon on friday. taking a look at the markets, dow industrials are up about 50 points this morning. the dow did much better, in fact, the whole markets did much better than we expected monday. tesla's down a bit, guys, but tesla rocked it yesterday, up about 8%. a little money coming off the table this morning. >> you never know how the markets are going to react. >> they did not react the way we thought, that's for sure. >> wouldn't be the first time. >> no. >> thank you very much. 6:57 right now.

we stop that radar in real time. you'll notice a lot of heavy activity has now pushed to the east of san jose. we're getting a little bit of a break for now from santa rosa south through san francisco and down the peninsula. as we head throughout the day, though, we have more on the way as the core comes through. a lot of instability around that core of low pressure. and for us, that could translate to some strong pop-up thunderstorms. that's what we will be watching for you. i have updates for you every 15 minutes throughout the "today" show. >> these conditions have created a real problem for drivers. anthony, one thing you're tracking, 680, a binch of incidents. >> a sig alert earlier with the jackknifed big rig and it remains to be closed, 680 at north mission boulevard so that will stand for the next half hour. avoid that area if you can. 880 is starting to slow. we actually have a new sig alert, 880 northbound at 23rd avenue. you'll notice as we take a live shot out there, it is stop and go on 880 northbound. once you get past 23rd it picks up. once you get to the bay bridge
