Heavy rain and snow on the way this week

Take advantage of the dry weather while it lasts. 2 separate storm systems are on their way to Northern California this week, and are expected to result in heavy rain and snow across the region. We are dry for the start of your Monday, but we will have the potential for some scattered sprinkles ahead of the storm moving in tonight. Valley areas will likely get a trace of rain through the day today. Temperatures are starting out in the low 40's to low 50's in the valley this morning, and in the 20's to mid 30's in mountain areas. Winds are out of the East to 10mph this morning, and will be out of the Southeast to 10mph this afternoon. High temperatures are expected to be very warm. Valley areas will top out in the high 60's to low 70s, and mountain areas are projected to end up in the mid 50's to low 60's this afternoon.

The first substantial wave of moisture is projected spread across Northern California after 8pm tonight. Showers will intensify late tonight through tomorrow morning. Very heavy rain and snow showers will be in store for your Tuesday morning commute, but snow levels will stay slightly above pass levels. Temperatures will be warm in the morning, then much cooler for the afternoon. Most areas will end up around 10 degrees cooler than Monday. Snow levels will more than likely fall to around 4000' to 5000' by Tuesday evening. The heaviest amounts from this first round of wet weather will occur between 2am and 2pm on Tuesday. Up to an inch and a half of rain will be possible in the valley during that time, and twice that will be possible in the mountains. Showers will persist through Wednesday, but will not be as strong as Tuesday. The majority of the showers will be in the mountains on Wednesday. Temperatures will become even cooler, with the valley topping out in the low to mid 50's for the end of your work week.

The next wet system will impact Northern California from Thursday through Saturday. Snow levels will likely dip to around 3000' to 4000' from that system. Rain and snow amounts look to be on par with the first system, but snow totals will be higher due to the lower snow level. The heaviest precipitation from the second system will likely occur on Thursday, with showers becoming more scattered on Friday. The potential for valley thunderstorms will also pick up on Friday. The chance for showers will last into Saturday, but mostly in the mountains. Dry weather will then return to the majority of Northern California from late Saturday through Sunday.

Rain showers and a good chance for thunderstorms are on the way for your Friday night and Saturday forecast. We'll also be much cooler and have gusty South winds this weekend. Some showers are possible early next week, but dry and warmer weather returns for the middle of next week.
