Rain and snow returned to Northern California this weekend. . A Winter Storm Warning is in effect through 6pm Monday due to this latest storm. Snow levels will rise on Sunday night and will mostly end up at around 5000' by Monday afternoon. Up to around a foot and a half of more snow can be expected and we could see some higher peaks with snow totals up to 3 feet. Chain requirements are expected in the mountains Sunday and into Monday at least.
Valley rain will be heavy at times and most of the valley is projected to get up to another 1-2 inches of rain through Tuesday. Temperatures will top out in the mid 40's to low 50's in the valley on Monday. Low temperatures will be dipping into the 30's in the valley during that time. High temperatures will end up in the mid to high 30's in the mountains, and low temperatures will dip into the teens to 20's overnight this weekend.
The rain and snow from this wet system will continue on Tuesday, but snow levels should mostly be above pass levels by that time. Temperatures will become slightly warmer towards the middle of next week, but should mostly stay below average for this time of year. The current outlook has a break from the rain projected for a brief period later on Wednesday, but that could end as early as Thursday night. Another wet system will bring moderate valley rain and high elevation snow back into your forecast towards the end of next week.
