Major winter storm brings severe weather to Northern California this week

Heavy rain/snow, low snow levels, gusty South winds, and thunderstorms are all ahead for Northern California

Posted: Feb 28, 2018 6:33 AM

The break from the wet and active weather is coming to an end today, and it looks like you can expect severe weather through the end of the week. A WInter Storm Warming will go into effect at 4pm this afternoon, and stay in place until 10pm Saturday night for areas above 2000'. We have already been tracking snow showers through the Northern Mountains this morning, and precipitation is going to spread across the entire region today. Most areas of the valley and Sierra will stay dry through around noon, with showers arriving later today. Snow levels are expected to be between 2000' to 2500' at the onset of precipitation, but that will quickly drop to around 1000' by Friday morning. Temperatures are starting out in the mid 30's for the valley this morning, and mountain areas are ranging from the high single digits to 20's early today. Winds will be out of the South to 15mph this afternoon. High temperatures are projected to end up in the mid 50's in the valley today, while mountain areas mostly climb into the high 30's to mid 40's. Rain and snow showers will intensify this evening.

Heavier rain and snow showers, the potential for valley thunderstorms, and stronger South winds will be ahead for your Thursday. Snow levels will mostly be down to around 1500', with the heaviest snow expected in the afternoon and evening. Valley areas may get a brief break from the heavy precipitation mid day, but could also have thunderstorms developing in the afternoon. These thunderstorms will be capable of producing hail, and will be accompanied by very strong South winds. Sustained winds will be up to 30mph out of the South on Thursday, with gusts to 40mph. Snow levels get a bit lower on Thursday night into Friday morning. We will have a decent chance for snow in the Northern end of the valley by Friday morning. Rain and snow showers then continue into your Saturday. 8 to 16 inches of snow will be possible down to 2000', 2 to 4 feet of snow will be possible above 3500', and 4 to 6 feet of snow will be possible above 5000' from Wednesday through Saturday. Temperatures will stay cool through early this weekend, with minor warming expected on Sunday into Monday. A break from the wet weather is on the way from Saturday evening through Tuesday, but more wet weather looks likely for the middle to latter part of next week.
