Low pressured centered along the coast of Northern California has brought very acrtive weather to our region today. Heavy showers, high elevation snow, and thunderstorms with heavy rain and hail have all been experienced through the day. Thunderstorms have been observed in Shasta, Tehama, Glenn, Yuba, and Butte Counties. Butte and Tehama Counties had the biggest impacts. Winds have been out of the South to around 15mph, with gusts up to around 20mph. We have a Flash Flood Watch in effect for the valley and foothills through 9pm tonight. Localized swelling of small rivers and streams, ponding on roadways, and debris flow around burn scars are the biggest concern. A Winter Storm Warning is also in effect through 5pm Tuesday for areas of the Sierra above 6000'. Up to 8 inches of snowfall is possible, with up to a foot of snow in some localized areas. Thunderstorms are expected to continue through at least 7pm tonight, and showers will linger after that.

We are expecting some clearing on the way for your Tuesday but there will still be a very decent chance for showers in portions of Northern California tomorrow. The best chance for showers and thunderstorms will be in the mountains and foothills on Tuesday. Snow levels will be down to around 6000'. Valley areas will be mostly sunny but will still have a slight chance for showers in the afternoon. Temperatures are projected to start out in the 40's to low 50's in the valley and end up in the low to mid 70's in the afternoon. Foothill areas will dip into the 40's overnight and will end up in the 60's on Tuesday afternoon. Mountain areas will dip into the 30's to 40's tonight, and will end up in the 50's to low 60's on Tuesday afternoon. Winds will be out of the South to around 15mph.

There will still be a slight chance for some scattered Sierra showers on Wednesday, but the remainder of Northern California is expected to be dry. Valley areas will end up back in the mid to high 70's in the afternoon, while foothill and mountain areas clim back into the mid 60's to low 70's. High pressure bulding into our region through the rest of the week and weekend will restult in average to above average temperatures, and dry weather ahead in your extended forecast. We will see some clouds returning but showers are not expected to return later this week. Valley temperatures will end up back in the low 80's late this week, and are then projected to climb into the mid 80's this weekend. The warming will continue through the start of next week and current projections have valley areas back in the low 90's for your Memorial Day Forecast. Foothill and mountain areas will end up back in the 70's by this weekend, and will then end up in the 70's to 80's on Memorial Day. Conditions will be great for camping this weekend!

The fog tucked us in last night, leaving for some surreal driving conditions on the roads. We see the potential for a repeat situation this evening for the valley.
