Sacramento, California – Rain and mountain snow could impact Northern California Feb. 18-22, with colder-than-normal temperatures increasing snow risks.
According to the National Weather Service 6-10 Day Outlook issued Thursday, Feb. 12, precipitation across Northern California is leaning above normal, with a 60-70% probability of wetter-than-average conditions during the Feb. 18-22 period. At the same time, below-normal temperatures are favored at an 80% probability, signaling a notably cooler pattern.
Valley locations including Sacramento, Redding and Chico are expected to see periods of steady rain. However, with colder air in place, snow levels could drop, increasing the potential for snow in foothill communities during overnight and early morning hours.
The Sierra Nevada, including Donner Pass and areas along Interstate 80 and U.S. Highway 50, may see accumulating snowfall during the period. Lower snow levels could create travel concerns across mountain corridors and higher terrain.
The combination of above-normal precipitation probabilities and strongly favored below-normal temperatures raises the risk of winter travel impacts, particularly across the Sierra and northern interior ranges.
For commuters and college students returning after President’s Day week, fluctuating rain and snow could create slick conditions along Interstate 5, Interstate 80 and Highway 99, especially during early morning hours.
The National Weather Service notes that 6-10 day outlooks reflect probability trends rather than exact storm totals. Residents are encouraged to monitor updated forecasts for refined timing, snow levels and accumulation estimates as the period approaches.
