Grab your umbrella, put on a jacket, and give yourself extra time to get to where you need to go over the next couple of days. Very active weather has returned to Northern California overnight. Valley areas can expect rain and a very decent chance of thunderstorms today. Mountain areas will have rain and snow in the forecast, and snow levels will be dropping through Thursday morning. Snow levels are above 5500' for the start of your Wednesday, but are projected to drop into the 4500' range later today. Rain will be heavy this morning, and then become more scattered into your afternoon. Thunderstorms could produce pockets of heavy rain, which could result in some minor flooding. Winds will be much stronger today. Sustained winds will be up to 25mph out of the South, with gusts up to around 35mph. Temperatures have dipped into the 40's to low 50's in the valley overnight, and into the 30's to 40's in the mountains. High temperatures are projected to top out anywhere from the mid 50's to mid 60's in the valley today, and in the 40's to 50's in the mountains this afternoon. Up to 2 inches of rain could fall in the valley through Thursday, and up to 3 feet of snowfall can be expected in the higher elevations of the mountains. Upwards of a foot of snow looks likely down to around 5000'.
The rain, snow, and thunderstorm threat will continue in your Thursday forecast, but activity will be more scattered than what's ahead for your Wednesday. Snow levels are projected to dip to around 3500', which means some areas of the upper foothills may get some light snowfall. Winds will be out of the South to around 20mph. Travel impacts will be likely in the mountains over the next few days, so you're encouraged to avoid mountain travel if possible. The threat of active weather will taper off heading into your Friday forecast, but there will be a chance for some active weather lingering in the mountains for the end of the week. We will warm up as we dry out on Friday. Valley areas will climb back into the mid 60's with clearing skies, and mountain areas will mostly end up in the 50's. Dry and warmer weather is on the way for your weekend. Looks like we can expect mostly sunny skies, with highs in the low 70's in the valley on Saturday. More clouds are expected to move into our region on Sunday, but we'll stay dry and warm. Temperatures are expected to top out in the 70's again on Sunday. A modest dip in temperatures and the potential for wet weather will be returning on Monday night into Tuesday of next week.
