Its one of those mornings where youre like, man, the air feels really crisp and nice. Thats exactly what were seeing this morning. But it is very cold in some spots, and now we are tracking our next chance of rain. And as you very well know, we have been talking about it. We do have our very own stormranger, and it is up and it is scanning. And its all set and ready to go for the arrival of not one but two storm systems headed towards the bay area. So ill give you a time line on that. Lets talk about these current temperatures. Because, boy, look at these 20s in the north bay. 27 degrees right now in santa rosa. 27 degrees in napa. And then down near morgan hill, also in the 20s. So really just a lot of these interior valleys. As forecasted, really had some freezing temperatures and we can expect to see these 20s slowly starting to warm up but not much. San jose 36 right now. Hayward, 35. And a quick reminder, we have a couple freeze warnings in place. And thats in place for san benito and Monterey County. So where you see the highlighted purple, thats a freeze warning. We did see a couple spots in the Higher Elevation areas, the Monterey County area with a hard freeze. And we can expect to see frosty conditions. If you wake up this nqrning and see some frost on your windshield, thats probably why. Now, as for the bay area, overall, were okay. No freeze watches for our area or warnings. But its still cold out there. Another thing youre going to notice into the afternoon is once the sun comes out into the dinner hour around 6 00, 7 00, 8 00, well start to see some breezy conditions yet again. Not as windy as it got in some spots yesterday, but still enough to be a little bit noticeable. Especially near livermore, 15 Miles Per Hour. O orinda, 19 Miles Per Hour. 18 Miles Per Hour in San Francisco. Half moon bay, 22. Skmoe san jose, 13 Miles Per Hour. Whenever it gets windy, the wind chill really makes it even colder out there. Its what makes it feel colder than it really is. Thats what a wind chill stands for. East san jose expecting a high of 57. So the good news, we will be 3 to 4 degrees warmer in some spots. At this hour than we were yesterday. Concord, 60 degrees expected for today. Danville, 59. Oakland, 56. Along the peninsula, well stay in the low to mid 50s for the most part. San francisco, topping out at about 55 degrees. 53 for the embarcadero and for the north bay, upper 50s. 50 degrees for sonoma, novato at 58. So lets talk about that rain. We have a number of systems but the one that could possibly bring a couple of spotty showers late into tomorrow night for the north bay is making its arrival in i want to say between 8 00 or 9 00. Far north bay. So were talking ukia area could see showers. Look at this fast forward time line through monday, by 9 00 a. M. , right before the Early Morning commute and through the morning commute, a chance of seeing some widespread showers. Now, that one, its not really going to bring a significant amount of rain total, but then weve got another one on the way. And this one is expected to make its arrival on thursday. And that one is really going to be widespread from thursday through friday, possibly even creeping into your saturday. Another thing youre going to notice, more snow is on the way for the sierra. Even though already got a good amount of snowfall. So definitely expecting a pretty active next couple of days. So lets go ahead and look at the next seven days. 51 degrees as we head into monday. Monday, thursday and friday, those are the three days that were monitoring right now. With stormranger up and scanning for our next chance of rain. For today, no rain in sight. Kira . All right.
