You might want to take advantage of the nice weather we'll have outside today as big changes are on the way in your weekend forecast. High pressure off the coast of southern California is keeping us dry and warm today, but we'll see some changes compared to yesterday as low pressure starts to track towards us from the Gulf of Alaska. We're starting out with mostly clear skies over northern California for the start of your Friday morning, but we'll have clouds increasing throughout the day. We'll end up mostly cloudy in the Northern Mountains, and partly cloudy across the rest of our region this afternoon. We're also expected to stay dry through at least early this evening. Temperatures are starting out in the 40's to 50's in the valley, in the 30's to 40's in the foothills, and in the 20's to 40's in our higher elevations this morning. We'll have winds out of the south to around 10mph, with gusts up to 20mph this afternoon. High temperatures will be a couple of degrees cooler than Thursday. Valley areas are projected to end up in the upper 70's to lower 80's, while foothill and mountain areas top out in the 60's to low 70's this afternoon. Partly to mostly cloudy skies are on the way for tonight, and we'll have a chance for a band of moisture bringing modest showers across our region late tonight through early Saturday.

Saturday will be cloudy, much cooler, and we'll have the chance for more light to moderate showers through the day. Models are still showing the best chance for wet weather staying in our far northern zones on Saturday, but we could see some limited shower activity further to the south. Our mountain areas and the northern end of the valley look like the best bet for decent shower activity through the day on Saturday, and then we'll have an increasing chance for showers over our entire region on Saturday night. Temperatures will only top out in the mid 60's in the valley, and in the 40's to 50's in the foothills and mountains on Saturday afternoon. The Winter Storm Watch has now been upgraded to a Winter Storm Warning for portoins of the northern Sierra above 4500' from 11pm Saturday through 11am Monday, as snow is expected to become heavier during that time. A Winter Weather Advisory has also been issued for portions of Lassen and Plumas Counties from 11pm Saturday through 11pm Sunday. Snow levels will start out down to around 4000' to 4500' Saturday evening, and could potentially dip to 3000' on Sunday. Even lower snow levels are possible Sunday afternoon through very early Monday, with the current projection putting 2 inches of snow in Paradise during that time. Valley areas can expect heavier rain during the day on Sunday. We'll also have gusty south winds developing through this weekend, and could even see the potential for thunderstorms or funnel cloud formation on Sunday afternoon. Sunday looks like it is shaping up to be a very active day across northern California. Travel impacts will be very likely in the mountains. Snowfall projections are showing 1 to 2 feet of snow in areas above 5000', a half a foot to a foot down to 4000', and some areas down to as low as 2000' potentially getting an inch or two of snow from Sunday afternoon through early Monday. Rain totals are currently projected to end up in the quarter inch to an inch range in the valley, and in the 1 to 2 inche range in our foothill and mountain areas. You can also expect Sunday to be the coolest day of your extended forecast, with high temperatures in the 50's in the valley, and in the 30's to 40's in our foothill and mountain areas.

Some scattered showers are expected to linger in our region on Monday, with most of that wet weather expected in our higher elevations. Temperatures will end up warmer on Monday afternoon. Most areas are expected to have similar temperatures to what we'll see on Saturday. High pressure building into northern California on Tuesday will bring a return to dry and warmer weather to our region. Valley areas will end up back in the 70's on Tuesday, and will then climb back into the upper 70's to mid 80's for the ramainder of next week. Foothill and mountain areas will end up back in the 60's to 70's by the middle of next week. Dry weather is expected for the rest of next week after the showers wrap up Monday evening.
