Below freezing temperatures and patchy frost are being seen this morning again. Highs clouds are also moving in which will leave us with partly cloudy skies through your afternoon and highs in the low-50s across the Valley. Lows tonight drop into the mid-to-upper 30s in the Valley with lows in the 20s in mountain locations.
A system moves in on Wednesday which brings the chance for showers on Wednesday morning across Northern California with lingering showers in the afternoon. If the showers move in early enough, low elevation snow (below 1,000 feet) will be possible, including the city of Redding. Accumulations this low are not expected as snow levels rise to 3,000-4,000 ft after sunrise. 1-4 inches of snow are expected mainly above 4,000 feet. Highs also stay in the mid-40s on Wednesday, so expect a very cold afternoon. Rain chances linger on Thursday, with a few moments of sun also possible, highs in the upper-40s to low-50s. Friday will be a dry day for most, a few mountian showers possible, maybe one making it into the North Valley.
On Saturday, a winter storm moves in causing widespread light to moderate showers in the Valley with snow levels at 5,000-6,000 feet. More rain is expected on Sunday with snow levels dropping to 4,000-5,000 feet. This could cause mountain travel impacts during the pre-holiday weekend. The wet weather begins to clear out next Monday.
