Our recent warm weather will give way to much colder (and wetter) weather Tuesday! Look for Valley rain and low elevation snow over the next couple of days.
A cold storm from the Gulf of Alaska will bring us big changes, which start Tuesday. Look for rain to move in, with about 1/4" to 1/3" for the Valley. Snow levels will start around 4000' Tuesday morning, then drop to around 3000' by Tuesday afternoon. That means the Ridge should see rain for most of the day Tuesday. If we see any clearing Tuesday afternoon, a thunderstorm could develop in the Valley... but I think that's a pretty small chance.
The steady rain turns to off-and-on lighter showers Tuesday night and Wednesday, but that's when the really cold air from the Gulf of Alaska pours on in. Snow levels will plunge to around 2000' in the Sierra, and could get near 1500' in Shasta County. Snowfall amounts will lessen by then, but that's when the best chance of snow in Magalia or Paradise will be. I think we're only looking at a couple of inches in Magalia & upper Paradise. Below Wagstaff Rd, it's probably only going to be a dusting.
Skies will turn partly cloudy by Wednesday night, and that's when it will get really cold. Valley lows should drop into the 20's the morning of both Thanksgiving and Black Friday... dress warm for those Thanksgiving morning runs like the Turkey Trot or Run for Food, and for Black Friday shopping! A few flurries are possible in the Sierra Nevada on Thanksgiving, Friday and Saturday... but the lower elevations will be dry.
If you're going over Donner Summit, Siskiyou Summit or the other passes of northern California over the next couple of days... expect winter driving conditions, and there's a good chance you'll need chains or a 4 wheel drive.
