Make sure to grab your umbrella before you head out the door this morning, and give yourself a couple of extra minutes to get to where you're going today. More scattered rain and snow showers, and the potential for thunderstorms are on the way in your Wednesday forecast. A Winter Storm Warning is in effect for portions of the Sierra above 4000' through 11pm tonight. Snow levels are hovering between 3000' to 4000' through this afternoon, and will get slightly lower later this week. Roads will be slick from the wet weather today, and drivers are urged to be careful for the next several days. Temperatures have dipped into the mid to high 40's in the valley overnight, and into the low to mid 30's in most mountain areas. Winds will be out of the South from 10 to 15mph today. High temperatures are projected to climb into the mid 50's for the valley, and into the high 30's to mid 40's in the mountains this afternoon. The heaviest precipitation looks like it will be this morning, but that could change if thunderstorms develop this afternoon. Thunderstorms could bring localized heavy rain, and the potential for hail this afternoon.
The next heavier wave of moisture will arrive late tonight, and ramp up into the early morning hours on Thursday. Precipitation will be more substantial than today, and snow levels will dip to between 2500' to 3500'. Temperatures will be slightly cooler for the end of your work week. The potential for thunderstorms will continue for the next several afternoons in the valley. Rain and snow will continue to be in the forecast for all of Northern California through Saturday. Most showers will subside by early Sunday, but there is still a decent chance for more Sierra showers to end the weekend.
Monday will more than likely be dry, and a little warmer than the weekend. Valley areas will end up back in the high 50's to low 60's for the start of next week. Another wet system then takes aim at Northern California on Tuesday, and will bring more rain and snow to the region. That wet system will more than likely last through Thursday of next week.
