We had a wet Christmas but today has been mostly dry and even sunny for the most part. Tonight will dip near freezing for many in the valley and in the teens in the mountains.
Tomorrow we'll see mid-50s for highs and some sunshine in the morning but once the sun sets, clouds will move in and so will rain & snow.
A low-pressure system in the Pacific will move inland just south of the Bay Area on Sunday. This will bring a good rain chance to our southern counties Sunday night into Monday morning. Our northern counties will likely see nothing. The farther south you are, the better your rain totals will likely be. I'm expecting no more than a quarter to half an inch in our viewing area in the valley. The foothills/mountains could likely see more.
Snow levels will be irrelevant in the Klamath mountains and Cascades as the rain & snow will not likely make it that far north. It will however impact the Sierra with snow levels around 3,000-4,000 feet. A deep trough of low pressure will allow for snow leels to get this low and for valley highs to be in the low-50s.
Tuesday will be a nice sunny day across most of our region as a small ridge of high pressure shifts over us. Valley highs will be in the mid-50s.
Another wet system moves in Wednesday. Rain will be possible Wednesday night into a part of Thursday. Hopefully by Thursday night most of the rain will clear so you can enjoy your News Years Eve outdoor plans.
Friday will mean the start of a new year and more seasonable weather. Highs will be in the mid-50s with partly cloudy skies.
More wet & snowy weather returns to our region next weekend.
