they did. based on a home value of $375,000, they estimate that a mortgage payment would go up from $1,436 to $1,479, an increase of about 43 bucks a month. third, you can expect to say slightly more in credit card debt. the personal finance site, nerdwallet, estimates the hike would boost the average annual cost of credit card interest by just $17. and that's just $1.40 a month. though people with lower credit scores and higher balances would likely pay more. and last, the folks at kelly blue book tell us there shouldn't be a huge impact if you're in the market for a new car they estimate an interest rate bump of .25 percentage points on a $25,000 loan would increase interest charges by only 5 bucks a month. good news about those student loans, too. most are fixed and they won't

pat? it is news 4 your health. new technology that could be a potential game changer for diabetics who constantly need to check their blood sugar levels. it's a device called the mini med 670 g. it acts as an artificial pancreas, monitors your glue koes levels every five minutes and pumps insulin without the need to calculate measurements. >> it's going to be liberating because diabetes is so dangerous and so taxing and so challenging to our bodies. >> the fda approved this device but it won't hit the market until next year. right now, the company that makes it is doing additional testing. wung thing the mini med cannot calculate, carbohydrates, hoping to improve that with the next version. the debate of e-cigarettes is heating up tonight, the

of e-cig explo ploeplosions spi recent years. the fda received reports of about 66 explosions in 2015 and early 2016. from 2009 to early september, they only recorded 92 explosions. last month a clerk at a liquor store in new york's grand central station had the e-cig in his pocket explode. that security camera there caught him trying to snuff out the sparks. he was badly injured. one seattle hospital says it has seen nearly two dozen patients with e-cigarette burns since october of 2015. explosive comments today after the collapse of a brief cease-fire in aleppo. human rights watch says the syrian city is being, quote, plunged into hell. the group says civilians are trapped there because of a new brutal air and ground attack. the organization wants syrian and rebel forces to halt the attacks so the people living in the city can get out. thousands of haitian

migrants are stuck at the u.s. border in mexico. they arrived after a long journey from brazil where they worked the rio summer olympic games. as nbc shows us, they fear they might have risked everything for nothing. >> reporter: in the heart of downtown tijuana, a taco stand that no longer serves tacos, owner jose luis gave up making them a month ago because there were so many haitian migrants in lunchline. every day more haitians arrive, famished, it's been a long trip on the road for three months over land from brazil. after the 2010 earthquake, brazil granted visas to more than 50,000 haitians, mostly to work on olympic construction. then the olympics ended and there was no more work, but the u.s. offered them a lifeline, amnesty from deportation because of the conditions in haiti. so, many like this man ben

the way over mountains, through rivers and jungle. "we have friends that left brazil that didn't make it here" he says "some because it was too hard, some because they died." but about 5,000 haitians did make it to the u.s. border in tijuana. then in september the u.s. withdrew that offer of clemency claiming conditions in haiti had improved. now if any haitians show up at the border without proper documentation, they could be detained or deported. he traveled 11,000 kilometers to get here but he's too afraid to walk the last 500 meters to the border, almost certain he'll be sent back to haiti. so what now? "i can't say, it's hard," he says "you don't even want to think about it," i ask him. with the "no," he says "it's too hard." so he'll wait and hope the u.s. will change his mind again. >> the situation in haiti is stillnc

you know you go outside right now you're thinking, what are you guys talking about? seems so nice out here. boy, do big changes come very quickly tonight. >> yeah, i posted on twitter and facebook the windchills tomorrow morning, i mean, single digits. >> we go from 44 now to 5 tomorrow morning. in some locations. so quite the change for sure. out there right now, as we mentioned, not all that bad. you still have time to find that coat, maybe you got to buy a new coat this year. temperature, 44 degrees. winds are calm. if you walk out there, it's really not bad at all, but starting to see some cooler numbers back to the west. 34 winchester. 37 in hagerstown. 31 in thermont. notice oakland, 23 back toward garrett county. yeah, there it is. radar, nothing to show, but that doesn't mean we're not going it to see anything tonight. we've got the jet stream, look at this, right here,

that could create enough lift tonight to give us a couple of snow showers. not going to be much. we could see that. to the north of this line, right there, is the arctic air. it's poised to just move right on in here. let's show you future weather first. again, cloud cover through about 9:00. around 11:00, little bit of an outbreak of snow showers, maybe rain down to the south. maybe some flakes around the d.c. metro area. it will not last long. i'm not expecting this to accumulate on the roads especially. maybe on the cars and grassy surfaces but that's it. by 7:00 a.m., well, everybody just cold and look at the numbers now. 44 d.c. 19 columbus, ohio. 15 in chicago. and watch how these cold air -- this cold air just moves across our region. so by 8:00 tomorrow morning, we're at 22. chicago at 5 below. now, these are the temperatures. not the windchills. amelia draper and i have been dealing with this and talking about this all day. amelia, with 20, 30 mile an hour winds. windchills are going to be a major factor. >> that's why tomorrow is a storm team 4

friday as well. just brutal out there. the coldest it's been so far this season by far. take a look at when you're waking up to. it will feel like we're 5 to 15 degrees with the wind. it only gets worse as we head into the afternoon hours and it stays that way through friday morning. feeling anywhere from about zero to 10 above zero. friday, the temperatures start to come up a little bit and the winds relax so by friday afternoon and evening, it's just cold. the windchills aren't as dangerous. but it's still feeling about 20 to 25 and then after that, doug, wintery mix to deal with on saturday morning. >> yeah, that's why we're calling both thursday and friday weather alert days but also saturday here. now nyou notice saturday we're talking about 48 in the afternoon, but 28 early in the day. i want to show you what's going to be happening. i want to take you hour by hour on saturday. if you got plans, a lot of you are saying you're flying out saturday morning, could be delays on saturday because 28 degrees with rain, snow, or ice and it could be one of those three depending on where you are. i do think wre

some slick roads. this is something we're going to watch. 35 degrees at 11:00. wet roads continuing. notice the temperatures coming up. 44 degrees by 3:00. starting to get cold, or on the cold side, but warming and mild by 11:00. 11:00 at night, 55. so just on saturday, alone, from 28 to 55. and talk about sunday, look at the temperatures on sunday. up to 63 early in the day, but then dropping to 31 by the end of the day. so you mentioned a roller coaster, that's exactly what we're going to be seeing here the next couple of days. rain all day saturday. after that wintery mix early, rain again on sunday. some of that could be heavy at times then look at the temperatures into early next week, 32 on monday. 36 on tuesday. another chance of rain on next thursday and right now, christmas eve, we're going 50 degrees on christmas eve. much milder pattern coming in toward the end of next week. next couple of days, guys, brutal. we're talking weather alert. download the nbc washington app. a great time t

good evening, i'm shomari stone here in temple hills, maryland, where prince george's county police are processing a crime scene here at the shops at iverson, otherwise known as iverson mall. let me move out of the way. you can see right up there, there a scene, that is the entrance of iverson mall. police say a man crashed his car into the entrance. he stepped outside of the car and walked inside and said he has been shot. now, police right now are trying to determine where he was shot. i have an update from prince george's county police saying that there was a chase involving the victim's car near oxen run and 23rd. now, that means that there was a car that was chasing the victim's car that you're

at at iverson mall. right now police are trying to search for the other car. now, we do not know if that car was involved in the shooting. again, detectives right now are processing this scene. this car crash happened around 3:45. we do know that the victim is conscious. he is breathing. and i'm sure detectives have a lot of questions to ask him. so if you plan on coming to iverson mall to do your christmas shopping, stay away from the front entrance. security guards are telling people to enter the mall via the burlington coat factory. we'll bring you the latest on this story as it develops on our nbc washington app. live in temple hills, i'm shomari stone, back to you. >> shomari, thanks so much. work will start soon on a new bridge in busy tysons corner. >> it's a bridge that's not just for cars. the bridge will connect the east and west sides of tysons from joan branch drive to dolley madison boulevard with a goal of helping pedestrians and cyclist

and vehicles get across the beltway. >> adam tuss is live in tysons with a look at how construction will have to take place above moving traffic. adam? >> reporter: that's right, jim. you know, this is going to be a huge multimillion dollar project. let me show you exactly where it's going to happen, at jones branch drive above the beltway here, near the capital one headquarters and, yeah, all of this happening right above this busy traffic. what good is it if you can't get from here to there? well, in tysons, a place that's trying to redefine itself, getting around on foot across massive roads like the beltway is especially challenging. does it seem very pedestrian friendly to you? >> not at all. >> reporter: seems like it needs an extra connection maybe? >> yeah. i would think so. >> reporter: enter this new bridge project that will link the east and west sides of tysons with pedestrian and bike access as well as room for cars. >> it's a little over a half mile long and a big chunk of

will be a lot of construction. going to begin early next year were with so much development happening in tysons, both residential and office space, people simply have to have a way to get around. you might not think of a leisurely stroll over the beltway as appetizing but people who live in this area like bailey, this is critical. >> there are no sidewalks so it's really hard to walk, it's dangerous to walk from here to there or run even. so, i mean, it would be nice to have more footpaths, sidewalks, ways for pedestrians to get around. >> reporter: this construction expected to cost about $60 million. now coming up next hour at 6:00, i'll tell you why this bridge project could actually pay off before it's fully finished. pat, back to you. >> all right. adam, thank you. arlington county's board unanimously approved amendments to the county's towing laws in an effort to help protect drivers from predatory towing. among the changes, tow truck drivers have to take photos of all four

and when the driver picks up your car, a receipt has to state that the photos are available. property owners also have to provide more signage about parking restrictions and some fees for evening, weekend and holiday towing have increased by $25. heads up if you're traveling through the district. starting at midnight, the 30-day warning period is about to end for people who blow past the city's two newest speed cameras. those cameras are located along hillcrest drive and alabama avenue in southeast washington. the speeds for both locations, 25 miles an hour. if you're caught speeding by them, you could face a citation ranging from $50 to $300. tonight, arlington county students are concerned that their schools are becoming less diverse, even more segregated. some of them are pointing to a recent school board vote as the problem. our bureau

is live outside washington lee high school, and david, this is a debate that is entering the classrooms now. >> reporter: it sure is, jim. and this voice of concern isn't that of a parent, it's not that of a school board member, not that of a teacher. in fact, it's a high school junior, one that goes right here to washington lee high school whose op-ped is generating a lot of talk. written in an online student newspaper, getting thousands of shares, and sparking a lot of talk here in arlington, junior, matt, is behind it. >> arlington being that we have so many different people that emigrate to this region, we're really unique in that we have benefit of our students being able to have firsthand experience from a lot of these people. i don't want that to be taken away from our schools. >> reporter: it focuses on a recent school board vote shifting boundaries, relocating students starting with incoming freshmen next year. matt's op-ped states the board's redistricting removes more than a quarter of black students from his school, washin

high school. >> i think it's really imperative that if we're going to be in charge of the future that we are exposed to different cultures and i think this boundary change threatens that. >> reporter: he says it will also group together more lower income students, creating socioeconomic segregation. school board chair nancy van doren says this vote came after evaluating six different criteria. one of which, demographics, focusing on free and reduced price lunches. >> in looking at that statistic, related to the demographic criteria, we did not change the composition of our high schools by more than 1% in the next 4 years. >> reporter: what's more, she says it tackles the major issue of overcrowding. >> and teachers are using it to generate conversation which isn't a bad thing. >> reporter: matt's article is generating conversation at other arlington high schools. yorktown senior, graham, says it's now part of classroom discussions. while he likes the buzz, he feels it's misleading. >> those statistics which sound really big were not in the

context of the number of students being moved actually breaks down to being less than 100 students free and reduced meal being moved. >> reporter: coming up on news 4 at 6:30, the big push that one student is making that's got 11, 1,300 people and counting on. it's important to consider fire safety after you've hung your lights and decorations on your tree. the university of maryland did a fire demonstration today, one tree that was dry went up in flames in a matter of seconds. and another that had been constantly watered caught fire more slowly, but it still burned in just a matter of minutes. fire experts say you should water your tree every single day. also, turn off the lights when you go to bed. >> most fire deaths occur between the hours of 10:00 p.m. and 6:00 a.m. when we should feel the safest and that's when we're comfy in our own bed. >> another thing to keep in mind is

candles and space heaters are as far away as possible from the tree. police throughout northern virginia team up for a very important mission. coming up, how their effort will bring smiles to the faces of children well beyond the holiday season. and more than 20 arrests over her 80 years of life. new troubles tonight for a woman who's gained fame

back here at the live desk, we're just learning about another huge online hack. yahoo! just revealed that hackers stole data from more than a billion users. the tech company thinks it happened three years ago, and this is a separate breach from the one it disclosed just a few months ago. in september, yahoo! revealed a hack affected 500 million users. this time around, yahoo! says hackers may have stolen account holders' names, e-mail addresses, phone numbers and birthdays. in some cases, they even cracked the security question and

password. at this point, yahoo! doesn't think any bank account or credit card information has been compromised. at the live desk, chris lawrence. well, turning to the weather, we are bracing ourselves. we're battliening down the hatches. for how long? >> through the weekend because we're going to be first dealing with brutal cold. tomorrow and friday. then a wintery mix on saturday. falling temperatures on sunday. so a little bit of everything in this forecast. so let me show you your weather headlines. for tomorrow and friday, we'll have windchills ranging from about zero degrees to around 20. so it will be brutal out there. even dangerous at times. especially later in the day tomorrow on into friday morning. after that, we're dealing with the wintery mix saturday morning and freezing rain is in play. and then more rain to deal with on sunday. here's a look at your planner tomorrow. and there is a chance for some flurries and rain overnight tonight. so good news, we're hearing vdot and the district pretreating

sorry. i think that's a good idea because you can see by 6:00 a.m. we're already below freezing. 29 degrees. we don't go up, we actually fall throughout the day tomorrow and with the winds, they are going to be strong. windy from start to finish. during the morning, it will feel about 5 to 15 degrees out there. plenty of sunshine, but during the afternoon, that won't help us out much. only about 24 degrees tomorrow afternoon. so your thursday outlook, the weather having a high impact on your day. because of that, it is a storm team 4 weather alert day. make sure the kids are bundled up at the bus stop. i think recess will probably be indoors. that commute, i have a feeling a few of us are going to have some dead batteries tomorrow. i know i'm crossing my fingers. and if you're walking the dog, probably a quick walk. not just tomorrow but friday, even on into the weekend as well. as we transition from cold to soggy. so the travel forecast at least to close out the workweek looking good. saturday, looking bad. in fact, i would almost try to avoid travel right now saturday morning if at all possible. here's your friday.

talking about plenty of clouds and it's just downright cold. saturday, a high of 48. here's the thing. look at your hourly planner on saturday. we start out at 28. we're above freezing by the midday hours. we're just tracking rain. showers continue on into the afternoon and evening, it becomes mild. 11:00 p.m. on saturday, if you're out late for a holiday party, around 55 degrees at that point. then here's the other thing. 63 on sunday, well, that's during the morning hours. if you're heading out to church or grocery shop early. by the afternoon hours, we're in the 40s. more rain on sunday then just cold and at least we're not talking about a temperature roller coaster anymore on monday but a high only around 32, guys. >> all right. amelia, thank you. a local couple's plan to travel overseas for their son's wedding didn't happen. an expensive change in plans especially when the travel insurance they paid for didn't cover it. that's when they called nbc 4 responds and our consumer report
