Get ready for a very active day across Northern California. Rain, snow, thunderstorms and gusty South winds are all expected across our region today. Showers have persisted across our region overnight, but are mostly moving into the mountains for your morning commute. Scattered showers will start to pick back up mid morning, and heavier rain will pick up this afternoon. Thunderstorms will be possible across the valley today, and snow levels will be dropping in the mountains. Snow levels are starting out at around 7000' this morning, but could dip to as low as 5000' by this evening. Mountain travel impacts can be expected over the next few days. A WInter Storm Warning will stay in place for portions of the Sierra down to 6000' through 6am Friday morning. Winds are also expected to pick up today and a Wind Advisory will be in place for the valley until 5pm. Sustained winds will range from 15 to 30mph out of the South, and we'll have the potential for gusts up to around 40mph. Temperatures have dipped into the mid 50's in the valley overnight, and into the mid 40's in the mountains this morning. High temperatures are only projected to climb into the high 50's to mid 60's in the valley, and into the mid 40's to mid 50's in the mountains this afternoon.
Showers will become lighter and more scattered on Friday. Valley areas will see a chance for scattered showers, while mountain areas have a better chance for persistant wet weather through the day. Temperatures will end up back in the mid to high 60's in the valley on Friday afternoon. The next wet system is slated to return to Northern California on Saturday afternoon, and it will persist through early next week. Showers are likely from Saturday afternoon through Monday and we'll have a decent chance for thunderstorms again on Sunday. Temperatures will mostlly stay in the low to mid 60's through your weekend. Looks like the wet weather will become more scattered again for the start of next week. Scattered showers will be possible on Monday and Tuesday. Temperaures will warm back into the mid to high 60's in the valley for the start of next week. Another wet system will bring widespread showers to Northern California from Tuesday night through Wednesday. That system is not expected to pack as much of a punch as this current system, but conditions will be wet. A modest warming trend will return towards the end of next week.
