Take advantage of the dry weather today, as big changes are ahead for the middle of your work week. Skies have become cloudy this morning, but the chance of showers will hold off until late this afternoon or tonight. The clouds have helped to keep temperatures warmer for the start of your Tuesday. Valley areas have only dipped into the high 40's to mid 50's in the valley overnight, and into the low to mid 30's in the mountains this morning. Winds will be out of the North to 10mph early today, but will be shifting to the Southeast this afternoon. High temperatures will top out in the low 70's in the valley, and into the 60's in the mountains this afternoon. Showers start to look likely across the Sierra and Coastal Range this evening, and will then become more widespread late tonight. Snow levels will be relatively high as showers arrive, and will more than likely be up to around 6000'. There will be a chance for thunderstorms this evening.
Wet and cooler weather are ahead for your Wednesday. Snow levels will dip to as low as 5000', and up to a foot of snow will be possible on Wednesday. Showers are thunderstorms will be possible across the valley, but projections for rain totals do not look very impressive. Around a half an inch of rain will be likely in many valley areas, with the potential for heavier rainfall in areas where thunderstorms develop. Most of the active weather will wrap up late Wednesday night, but scattered showers will persist in the mountains on Thursday. A slight chance for valley showers will also be ahead for Thursday, but that doesn't seem like it will be much of an impact.
The next wet system takes aim at Northern California on Friday and will last into your Saturday. That system might be slightly wetter than the Wednesday system, but it isn't expected to bring any major impacts to our region. We'll dry out again on Sunday, but another wet system looks likely towards the beginning of next week.
