Skies became cloudy across northern California today, but we remained dry and warm. High temperatures topped out in the low to mid 70's in the valley, and in the 60's to around 70 degrees in the mountain and foothills. Breezy south winds developed through the day. Most areas saw winds up to around 10mph out of the south but Chico did register sustained winds up to 17mph earlier this afternoon .Modest winds are expected this evening.
A wet and cooler system will be dropping down into northern California from the Pacific Northwest through your weekend. The Natioanal Weather Service out of Sacramento has issued a Winter Weather Advisory for portions of Lassen and Plumas Counties from 5pm Saturday through 4pm Sunday. A cold front will move through our region and bring tempeeratures back down to around if not a little below average. Valley areas will start out in the low to mid 40's for your Saturday morning, and mountian areas will mostly dip into the 20's to low 30's again overnight. Foothill areas will dip into the mid to high 40's overnight. Temperatures are projected to top out in the low to mid 60's in the valley on Saturday afternoon, while foothill areas climb into the low to mid 50's and mountain areas end up in the 40's to low 50's. There will be a chance for showers down to as far south as the Shasta County mountains before the afternoon hours, and then a much better chance for mountain showers returning tomorrow evening. There will also be a very slight chance for some light precipitation in the valley. Snow levels will be down to as low as 4500' in the Sierra on Saturday and will then dip to below 3000' on Sunday morning. Moisture will be very limited by the time the snow levels dip into the foothills and minimal to no impact is expected from that low snowfall. Snow levels will be down into the 2000' to 3000' range in the Northern Mountains through this weekend. Most of the showers will head down to our South by early in the day on Sunday but some scattered showers may linger into your Sunday afternoon. Gusty winds will be picking up out of the North on Sunday. A Wind Advisory has been issued for the valley from 10am to 8pm on Sunday. Sustained winds could top out at around 30mph in the valley on Sunday and we could see gusts up to around 40mph. Temperatures will be slightly cooler on Sunday.
We'll have clearing skies and dry weather on the way for your Monday. Gusty winds are expected to continue through the start of next week, but are not expected to remain strong enough for the Wind Advisory to be extended. Dry and warmer weather is on the way through the middle of next week. High temperatures in the valley will climb back into the high 60's to low 70's on Monday and then back into the mid to high 70's for the middle of next week. Long range models are hinting at the potential for a wet system bringing rain and snow back to our region as we head into next weekend.
