You're going to want to keep that umbrella handy for the rest of the week. Heavier rain, gusty South winds, and the potential for valley thunderstorms are ahead for your Wednesday across Northern California. Precipitation ramped up a bit last night, but will become much stronger moving forward through Friday. This system is staying warm today, and that will result in snow levels staying above 6500'. We are not expecting much, if any, snow accumulation today. Temperatures are starting out very warm this morning. Valley areas have only dipped into the high 40's to low 50's overnight, and mountain areas are starting out in the low 30's to low 40's this morning. Winds are not impressive this morning, but will pick up through the day. Sustained winds will be up to 15mph out of the South, and gusts could reach 35mph this afternoon and tonight. There is a slight chance for thunderstorms in the valley this afternoon. Thunderstorms could be accompanied by heavy rain, strong winds, and hail. Please be cautious if you are driving through areas of hail, as it will make roads extremely slick. High temperatures will be in the same range as yesterday. Valley areas are projected to top out in the low 60's this afternoon, and mountain areas will end up in the mid 40's to mid 50's.

Heavier rain and stronger winds could result in falling trees. Trees into roadways causing travel issues, or trees into power lines causing power outages will be possible this afternoon through Friday. The heaviest precipitation is expected tonight through Thursday evening. More than an inch of rain will be possible in the valley during that time, and upwards of 2 inches of rain will be possible in the mountains. Snow levels are expected to drop drastically as a cold front pushes through the region for the end of the week. Snow levels could fall to between 3000' to 4000' on Thursday and Friday. Temperatures will become cooler for the end of the week as well, with valley areas topping out in the mid to high 50's for Friday and Saturday. Scattered showers will continue to be possible in the valley for the end of the week and start of the weekend, but mountain areas will more than likely get the majority of the wet weather to end the week. Showers will then mostly taper off on Saturday. Snow levels could dip into the 1500' to 2500' range this weekend, but moisture in our area will be very limited by that time.

Some mountain showers may linger into early Sunday, but most areas will by dry for the latter part of your weekend. Temperatures will end up back in the high 50's for the valley on Sunday, and will continue to warm for the start of next week. Dry and warmer weather is expected for next week. Valley areas could return to the low 70's as early as Tuesday. The current outlook for next week is dry and warmer weather ahead for Northern California.
