Sacramento, California – A wetter late-February pattern is taking shape across Northern California in the Feb. 21–27 window, with precipitation odds climbing to 60% to 70% and temperatures easing back toward seasonal averages.
According to the National Weather Service Climate Prediction Center, Northern California sits in a near-normal temperature zone for the 8- to 14-day outlook. Highs and overnight lows should align more closely with late-February standards after recent fluctuations, especially across the Sacramento Valley and Bay Area.
Precipitation probabilities are strongly tilted above normal, with a 60% to 70% chance of wetter-than-average conditions. For the coast and inland valleys, including San Francisco, Santa Rosa and Sacramento, that favors multiple rounds of rain. In the Sierra Nevada, colder air will support accumulating snow, particularly along Interstate 80 near Donner Pass and U.S. 50 over Echo Summit, where chain controls and travel delays are possible during active systems.
Communities in Redding and Chico may see steady rain with brief heavier bursts capable of ponding on roadways. In higher elevations, snow-covered roads and reduced visibility could develop quickly.
Drivers should monitor Caltrans updates and prepare for changing conditions, especially across mountain corridors.
The broader setup supports several systems moving through rather than a prolonged dry stretch. Additional updates from the National Weather Service may refine timing and snowfall potential as late February approaches.
