Hi vicky, Merry Christmas eve. Were tracking rain but dont let the dark clouds scare you off. Its a weak frontal system that will affect parts of the far northern bay. If youre heading out or driving to a familys house for Christmas Eve, looking at trivalley, 52 degrees, peninsula 53 and the south bay mild at 54. So were kept this cloud cover for the past couple of days in a row and thats whats been keeping that poor air quality. San francisco at 53 and the north bay is getting cloudy. Now, that storm system is expected to move in overnight and into early monday morning which is tomorrow, Christmas Day, but for now were going to keep that air quality forecast for the north bay, the east bay and the peninsula on the unhealthy side which means, yes, no wood burning allowed through tonight through Christmas Eve. I know it will be tough, people have beautiful fireplaces but you need to hold off on that. Tomorrow the air quality might get better. South bay, moderate conditions right now and those temperatures are actually expected to get slightly warmer. So well have a closer look at the timeline for the rain in the north bay and well talk about the chance to see sierra snow in just a bit. Vicky . Vianey, thank you.
