Cool and mostly dry weather pattern with light winds is expected to persist across northern interior California through Friday. Although, a weak surface high pressure is promoting a modest warming today. Afternoon highs in the mid 60s into low 70s for the Valleys, 55-65 in the Foothills and 50s-60s in the mountains today. Cold morning lows are expected for the mountains and higher elevation basins the next few days, with near to below freezing temperatures. Patchy fog or haze will be possible each morning in the Valley.

A larger upper-level trough is expected to deepen offshore Thursday and Friday, with a series of embedded weak shortwave moving across the area. This will bring a slight chance of isolated mountain showers over the Sierra. Elsewhere, will see mostly increasing mid to high clouds.
