Patchy fog will be possible this morning but the main concerns will be for anyone headed South towards Sacramento, whee the fog is expected to be quite dense. Themperatures are also quite cold across the Valley with a few near freezing. We'll stay sunny this morning as the sun rises but clouds move in during the afternoon with a band of rain sweeping the area after sunset throught Wednesday morning. Expect overnight temperatures to be a little warmer because of it. Snow levels will be 4500 feet will less than a tenth of inch of rain expected in the Valley.
A few lingering showers are possible in mountain locations on Wednesday. Another line of showers moves through Wednesday night through Thursday morning. This band looks to be a little more more concentrated, which means you could get a little more rain than the Tuesday system. Snow levels with this system will be down to 4,000 feet with a dusting possible in the uper foothills.
Friday through the weekend the wet pattern sticks with widespread showers expected and snow levels around 5000 feet. Highs also drop into the low-50s to the upper 40s in the Valley into the weekend and the wet & cold pattern parks itself over the region. Next week looks to be more of the smae. More daily rain chances and cooler temperatures. The extended climate outlook also has the wet pattern remaining through mid-January, which would be typical given the seasonal average.
