January 20, 2026 2:25 am
Southern California Overview:
- Above average temperatures and weak offshore flow will continue through Tuesday. Patchy low clouds and dense fog along the immediate coast tonight, with increasing chances of night and morning low clouds and fog into the middle of the week. A cooling trend begins Wednesday and continues through Friday as a low pressure system moves in from the Pacific, helping build the marine layer and extend low clouds and fog inland. This low will also bring a 10-20 percent chance of precipitation Thursday and Friday. Starting Sunday, dry conditions are expected to return with a warming trend and prevailing offshore flow.
- Lake effect snow expected downwind of the Great Lakes. Frigid Arctic airmass remains in place over Northeastern U.S. today before temperatures moderate on Wednesday. Freeze warnings in effect from southern Georgia down to central Florida.
