Rain and snow are already falling across the North State with below freezing temperatures in the mountains tonight and lows in the 40s in the Valley.
Today is a cool day and tomorrow is expected to be even cooler with highs in the mid-60s across the Valley due to a coold weather system that has moved in from Western Canada. Other than today, the next best chance for showers in the Valley are Sunday night and Monday morning, which would only be light to moderate showers.
Highs stay in the 60s on Monday with partly cloudy skies but the full sunshine returns on Tuesday with highs getting back into the mid-70s. This is due to a small ridge of high pressure that moves in from the Pacific. Highs in the upper-70s and low-80s can be seen on Wednesday.
This small system only lasts a day, and another cool system from the Gulf of Alaska sweeps down on Thursday and Friday. This system just avoids the North State, only impacting Washington and Oregon. However, since the system is there, we can expect highs to stay in the upper-70s to low-80s on Thursday and Friday across the Valley.
By Saturday a much stronger ridge of high pressure moves in from the Pacific, warming the Valley into the mid-80s on Saturday and likely continuing that warming trend into the following week, possibly getting back into the 90s.
