We saw another unsettled day around the North State on Sunday, and that will continue through Tuesday. Snow levels will plunge in the next couple of days, and snow is possible in the Valley on Tuesday morning!
Showers and afternoon thunderstorms rolled through the Valley Sunday, with more snow in the mountains. A wave in the Pacific will surge onshore tonight, bringing the steady rain back later tonight into Monday morning. The Valley rain & mountain snow will turn showery again Monday afternoon, with afternoon thunderstorms possible in the Valley.
Cold air will pour into the North State on Monday. This is a very cold airmass that we don't see very often, so snow levels will get low. Look for snow levels to drop to 2500' by Monday morning, down to 2000' by the afternoon, and down below 1500' Monday night. By Tuesday morning, they'll plunge to near 500', which means snow in Redding, and a rain/snow mix is also possible. Snow levels will rise above the Valley floor by noon, if not sooner. Moisture will really be drying up by Tuesday, so look for only a few showers in the Valley. But snow showers are possible in Redding!
We should dry up by Tuesday evening, and skies will turn sunny by Wednesday. We'll see a mix of sun and clouds Thursday and Friday, but we'll remain dry. Cold air will remain in place, so we'll stay chilly! Valley lows will plunge into the 20's, and highs will be lucky to reach 50... so most of our day, we'll see temperatures in the 30's & 40's. That's chilly!
A new storm will move in Saturday with rain. Since it'll be moving into a very cold airmass, snow levels will yet again be very low, and at this point, snow is possible in Redding and the Ridge again!
