child. this comes after another bay area child in alameda county tested positive for the virus. warnings have been issued against drinking raw milk after the virus was detected in retail samples. the virus has also been circulating among wild birds, poultry, and livestock across the state. hazy shade of winter hung over the bay area today, giving us the worst air quality we have had so far this winter. as for how it all changed so quickly today, meteorologist darren peck. >> yeah, we've had high pressure around for the last several days. what was it about today that caused the air quality to go down thil so much? you can see the pattern when you look at this map. there's clearly worse air quality in the central valley. and then if you follow the pattern, tracing it from the central valley to the bay, in other words, the parts of the bay that were close es to the central valley are the parts that had the worst air quality today. that is a clue into what

happened here. this might not have been entirely all our fault. in other words, all the wood burning fireplaces that are usually responsible for poor air quality this time of year when we get under centers of high pressure like, this i think we got an imported mass of poor air coming from the central valley. let's get over to the virtual set. we'll take a look at what the winds were doing at 11:00 this morning when the smoke started to -- it had really been infiltrating for several hours at this point. watch the way the wind's moving over here. coming in from the central valley. if i can walk back here, the air quality's always more problematic over here. but what happened over the last 24 hours, you kind of follow the streamlines here. there's the flow. we imported more of it. and if you take a look at what's going to happen as we get into tomorrow, the wind might work a little more in our favor, but i sdoebt think this is going to be strong enough to clear out what we've already accumulated here. and when we take a look at how things might change by monday, it'll get better. monday we're going to have stronger winds. they're

still coming from the central valley, but they're going to have more momentum to them, and i think they'll clear out a lot of that poor air quality and push it out of the by a. rain coming by the end of the week. really before next weekend. we're going to look at that coming up in the complete first alert forecast coming up in just a bit. >> thank, you darren. b.a.r.t. riders in oakland wore their favorite ugly christmas sweaters from past years or bought this year's version today for sweater fest at the rock ridge station. and caltrain riders got to enjoy the holiday train, complete with more than 70,000 glimmering christmas lights. it will be running all weekend from san francisco to the south bay. well, the season of giving is in full swing and thrive city for the annual toy giveaway. thousands of kids and their families lined up to ice skate, enjoy live music, and even pick out a toy of their own. reporter sooji nam with more on the holiday celebration. >> reporter: doors to the event

>> we're building community here. this is not just for one neighborhood or one organization, it's for everybody in san francisco. >> reporter: haney said they raised money over the last year to buy and collect more than 7,000 toys for the event this year. he added their mission is to especially help families that have been struggling to make ends meet. >> there are a lot of family, including right here in san francisco, who a toy means a lot to them. they don't have enough to be able to necessarily provide that for their kid. and so we all have to come together. >> reporter: ambassadors with a community outreach program said this event is something they've been looking forward to all year. >> oh man, it's been amazing. it's been so busy. you know, all these kids running around with toys that they love. it's really cool. it's really fun to see it all happen. >> reporter: a fun and festive celebration all for a greater cause. organizers said more than 1.4 million people face poverty all across the bay area. >> when there are families and

kids during the holiday season who are not taken care of, that's all of our responsibility. >> reporter: so events like joy to the city is much more than getting a free toy. >> a lot of rough times for a lot of people, and honestly, i wish i knew a lot sooner. i would have gave a lot more also to help with this, but i see a lot of kids who are, like, going through a very hard time financially and their parents can not do this. and things like this really make a difference. >> reporter: many say they're grateful the community is coming together as events like this show that one christmas toy can go so far for a family this holiday season. well, five years after a fire tore through the historic notre dame cathedral in paris, the building opened its doors to a new era. bells rang out for the first time since 2019. and inside a special ceremony to mark the re-opening as well as a tribute to the first

responders to the original fire. first responders or not, that cathedral was nearly destroyed and had been going through restoration work for the past few years. it will re-open to the public tomorrow. it was 83 years ago today in 1941, only 68,000 people lived in san jose, which was famous then for apricots and prunes and pears. the only chips in the valley were eaten at lunch, and almost nobody had ever heard the words pearl harbor. all that changed on this day at the break of dawn when japan desperately short of oil to fuel its war on china and in the pacific theater struck without warning on this day. and franklin roosevelt made the speech of a lifetime within 24 hours. >> yesterday, december 7, 1941,a date which will live in

infamy. as commander-in-chief of the army and navy, i have directed that all measures be taken for our defense. >> that attack killed 124 americans and injured many others. people come together on the shores of pearl harbor for a memorial. a wreath was placed near the wreckage of the uss utah to honor the lives of those crew members. and still ahead here at 11:00, a mystery in new jersey. big drones roaming its skies for a week now. who are they? where did they come from? what's going on? and why is the fbi getting involved? plus, the -- a bay area olympian is getting recognized in a special way. how barbie is honoring kristi yamaguchi.

that almost looks like a ufo. but the fbi is investigating a series of mysterious lights that have popped up throughout the new jersey skyline over the past several days. >> they were seen from president-elect donald trump's national golf club in south new jersey. the fbi believes these clusters of objects are possibly drones and are asking people on the ground for any information or videos they may

have of those drones. >> local police say there's no immediate danger to the public, but on the other hand they don't have an explanation for them, so how do they know? that hasn't stopped residents from coming up with their own theories. >> the rumors go from russian spies to people stalking trump top aliens. so nobody really knows what's going on. it's definitely concerning. no one can figure out why are they here. >> the federal aviation administration has banned drones over the nearby trump national golf club in bedminister and a nearby military installation. >> interesting. interesting. your explanation, mr. peck? >> i'm not even going to try on that one. >> you've got your hands full with other stuff. two things to talk about, the rain is going to be the headline, because the rain is coming back. it's been a while. >> talking the end of this coming week? >> at the end of this week but really like into next weekend. before we get there, it's going to get cold in the morning. i want to start out there. fist things first, tomorrow morning you'll feel this a bit but

it's really over the next couple of mornings, bottoming on tuesday. tuesday morning is the coldest morning coming our way in this seven-day forecast. want to show you what some of the numbers look like. a lot of low 40s down here in the south bay. temperatures in the north bay will do their thing. that happens when we get to our coldest mornings. they'll go down into the low and mid-30s up there. so heads up on that. daytime highs will get a little bit cooler. you may not notice that as much as you will early risers in the morning. and this is the kind of situation where we likely will be talking about some kind of frost advisory as we get closer to it. all right, let's get over to the forecast imagery, because now we want to turn our attention to this possibility for rain and see how likely this is and how much we might get, see what the storm track's doing out there, staying away from us. we can play it forward. on the big picture you see a series of storms starting on friday. the first one not all that much. there's going to be two after it that come through that start to look better. there's one that gets us from friday into

saturday. and then here's one that comes in for monday. i mean, we'll get way out here. take a look at the date up here, monday, december 16th. we don't want to go that far yet. it's a little too far to try and put specific forecast details together like that. it's interesting to see how it's coming together. let's slow it down and play it again for the first storm. that one we do want to start getting as much detail on as we can. thursday night a weak little system domes through. we don't get much from that. thursday afternoon into the evening. here comes the first one. that will be more notable measurable rain for us. starts on friday. goes through saturday. stopping it there. that gets us into friday night. deeper shades of green. still some left showers by saturday morning. that clears out through the remainder of saturday. this next one we'll hold off on for now. that one could have better rainfall totals, but those storms tend to always look -- if you go out like 10, 11 day, the storms typically tend to look more impressive than they

end up being. we're not going to play around with is that monday storm yet. instead, we're going to try and get a best estimate on how much rain we'll get from that main system that comes through friday into saturday. we'll look at two different forecast models for that. here's the system as it's seen by the american model. that's for the friday/saturday system. we get about 0.25 of an inch of rain out of it. this would be the european model, its depiction for that friday/saturday rain. numbers are bigger but still within the same ballpark. 0.25 of an inch of rain, 0.33 of an inch of rain. that gets us through friday and saturday. we will wait to see how things develop after that. let's get back to the virtual set. the one thing i would say about this is it does look promising after that for systems to continue to develop and keep coming our way with a chance of rain. could be active as we head towards the middle of december. but one seven-day at a time. here's the first one. got our rain on here for friday and saturday. right now most of that would be centered on friday. and then there will be

more to come if it works out, because we could use rain around here after all. more on that later. matt, over to you. >> coming up in sport, stanford and cal men's basketball opened up acc play, only fitting it was against each other. plus a quiet off-season thus far for the giants. that all changed earlier today. we'll introduce you to the latest free agent signing coming to san francisco.
