Cooler temperatures, breezy north winds, and the potential for some mountain showers are on the way in your Thursday forecast. We're starting out with clearing skies and warmer temperatures Thursday morning. North winds have helped to keep temperatures warmer in most valley and foothill areas this morning, but higher elevations are starting the day close to what we had on Wednesday morning. Valley areas are in the upper 30's to 50's this morning, foothill areas are in the 40's to low 50's, and mountain areas are mostly in the teens to 20's for the start of your Thursday. We'll have winds out of the north to around 15mph through the day, with gusts up to around 25mph possible. Northeast to east winds are expected in the Sierra and foothills for the early portion of the day before winds shift to become out of the south. Gusts up to around 30mph are being reported in some of our higher elevations in the Sierra and foothills this morning. High temperatures are expected to end up slightly cooler than Wednesday. Valley areas will mostly end up in the mid 60's, foothill ares will end up in the mid 50's to around 60 degrees, and mountain areas will top out in the upper 40's to upper 50's. The potential for showers will move into the Northern Mountains this afternoon and is expected to persist in that area through tonight. Very modest precipitation is expected through early Friday.
We'll be dry and a little cooler for most of the day on Friday, but the potential for modest widespread showers will move into our region Friday night through early Saturday. Temperatures are projected to end up in the mid 50's for the valley on Friday afternoon, in the 40's in the foothills and in the 30's to 40's in the mountains. Warm air advection will keep out temperatures warmer as light rain tracks through northern California early in the day on Saturday. Snow levels could dip to as low as 2500' during this first wet push, and we could see modest amounts of snow sticking down to around 3000'. This will likely bring some travel impacts to areas of I-5 north of Redding from Friday night through mid day Saturday. Mostly mountain showers are expected to linger into Saturday afternoon before we see another wave of moisture track through our region from Saturday night through early Monday. Sunday looks to be the wettest day of your extended forecast. The current outlook brings a quarter to 3 quarters of an inch of rain to most of the valley, around an inch to an inch and a quarter of rain to the Redding area, and between an inch to 2 and a half inches of rain to higher elevations through this weekend. Snow levels are currently projected to dip to around 4000' in most areas on Sunday. This is great news for our moisture starved region. Temperatures will be warmer overnight, but much cooler for the afternoons. Valley ares will mostly stay in the low to mid 50's for high temperatures this weekend, while mountain and foothill areas have high temperatures in the 30's to 40's. A lull in the showers is expected during the day on Monday, but models are showing more chances for showers moving through towards the middle of next week. We'll have more details on the wet weather projected for next week as confidence builds over the next few days. Make sure you've got a waterproof jacket handy and dig that umbrella out from the back of your closet!
