Cool, windy, and active weather continued across northern California today. Light to moderate showers moved through the valley earlier in the day before heavier showers and thunderstorms moved through early this afternoon. A thunderstorm brought heavy rain to portions of Tehama County between 2 to 3pm, and Red Bluff recorded nearly a half an inch of rain during a half hour time span. We also had thunderstorm activity between 4:30 and 6pm in Butte County. Hail has been confirmed in Redding, Corning, and Oroville this afternoon and evening. Foothill areas have seen a mix of rain and snow, and mountain areas have mostly seen snow through the day. The Winter Weather Advisory has been extended through 8pm tonight in Trinity County and will continue through 11am Wednesday in Shasta County and the Western Slopes of the Sierra. An additions 4 inches of snow will be possible down to 3000' in the Northern Moutnains, and we could see snow levels dip to as low as 1500' overnight. Portions of the Sierra above 4000' could still see an additional 12 inches of snow through tomorrow, with a dusting of snow possible down to as low as 2000' on Wednesday morning.
The heaviest showers are expected to last into tonight, and then will become lighter and more scattered on Wednesday. We'll have a decent chance for showers and the potential for afternoon thunderstorms in the valley. Foothill areas will have a chance for rain and snow showers as well as a slight chance for thunderstorms in the afternoon and evening. Mountain areas will mostly see light to moderate scattered snow showers on Wednesday. The heaviest showers on Wednesday are expected to be in the afternoon hours and could persist into Wednesday evening. Temperatures will start out in the 30's to 40's in the valley on Wednesday morning and will top out in the mid to high 50's. Foothill areas will dip into the mid to high 30's overnight and will end up in the mid to high 40's on Wednesday afternoon. Mountain areas can expect low temperatures in the teens to 20's on Wednesday morning and will top out in the 30's to 40's.
Valley areas are expected to stay dry on Thursday and Friday, but we will still have the chance for scattered mountain showers on Thursday afternoon and evening. We'll be slightly warmer for your afternoons late this week, but overnight low temperatures will stay chilly. Valley aresa will have low temperatures in the mid 30's and high temperatures in the low 60's. Mountain aras will dip into the teens to 20's for your morning hours and will top out in the mid to high 40's for your afternoons on Thursday and Friday.
A wet system is projected to move through the Pacific Northwest this weekend and the southern portion of that system will bring a decent chance for light showers to northern California on Saturday. Light showers and high temperatures in the mid to high 50's can be expected in the valley. Mountain areas will have the chance for rain and snow showers and high temperatures in the mid 40's on Saturday afternoon. We'll still have a slight chance for showers on Sunday but should be warmer than Saturday. High temperatures in the valley are currently projected to top out in the mid 60's. The potential for more wet weather is possible next week. We'll get a much better idea on the timing and strength of any more showers ahead over the next few days.
