It was a foggy beginning to Tuesday for the valleys of northern California, but most of the afternoon was bright and breezy with above average highs. We will have fewer foggy areas tonight, and we can expect a colder to start Wednesday morning. A small storm brought light amounts of valley rain and mountain snow late last night, followed by valley fog this morning and breezes this afternoon. The breezes will continue tonight and Wednesday, and that will lead to less morning fog. Lows under a mostly clear sky will range from near 10 in the coldest mountain areas to the 20s, 30s and 40s at the lower elevations. Highs tomorrow will be above average with more breezy sunshine, ranging from the 40s in the mountains to the 50s and 60s in the foothills and valley.
The ridge which will be overhead Wednesday will begin to give way to the first of two additional storms late this week and this weekend, and they'll deliver more rain, snow and wind along with cooler air than last night's storm. We can expect increasing clouds on Christmas Eve Thursday, followed by valley rain and mountain snow Christmas Day Friday as well as Saturday. We will have a brief break between storms before the next chance for valley rain and mountain snow arrives Sunday and lasts through early Monday. This second storm isn't looking as big as it did yesterday. Highs will range from mountain 40s to valley 50s.
