Friday was anorther mild and very comfortable day across Northern California. Skies were sunny to mostly sunny, temperatures were slightly above average, and Winds were out of the Southwest to around 10mph. High temperatures mostly topped out in the low 80's in the valley, and in the low to mid 70's in the foothills and mountains. Tonight will mostly be mild across our region, but we will have a slight chance for scattered showers in the Northern Mountains.
Low pressure centered in the Gulf of Alaska will be bringing some changes to your weekend forecast. Temperatures will be cooler, winds will be stronger, clouds will be increasing and we'll have the chance for showers and thunderstorms on Saturday. Showers will arrive in the Northern Mountains early to mid day, and then will spread through the valley and Sierra after noon. The best chance for showers will be in areas closest to the Oregon border, with the potential for wet weather diminishing to the South. The heaviest showers are expected to be in higher elevations. The best potential for thunderstorms will be in areas of Shasta County, the Southern Cascades and the Northern Sierra Saturday afternoon and evening. There will also be a slight chance for thunderstorm activity in the foothills. Mid valley areas will have cloudy skies, with a chance for some showers late in the day on Saturday. Winds will be out of the South to around 20mph, with gusts up to around 30mph. Temperatures will start out in the low to mid 50's in the valley and end up in the mid 70's in the afternoons this weekend. Foothill areas can expect low temperatures in the 40's to 50's and high temperatures in the mid to high 60's this weekend. Mountain areas will dip into the 30's to low 40's overnight and will end up in the low ot mid 60's through the weekend. There will still be a chance for some light showers on Sunday, but thunderstorms do not look as likely.
High pressure will be building into Northern California through the week next week. We'll be dry and sunny to mostly sunny on Monday. High temperatures will end up back in the high 70's to low 80's in the valley on Monday afternoon, while foothill and mountain areas end up back in the 60's to 70's. We'll be staying dry with sunny to mostly sunny skies, and a warming trend on the way for next week. Valley areas are currently projected to climb into the mid to high 80's on Wednesday, and into the low to mid 90's late next week.
