From Meteorologist Chad Crilley on FB: (11/12/26) Thursday FULL Forecast - Rain, Wind, and High Surf Return as Winter-Like Pattern Arrives
A pattern chance has started across So Cal as clouds return this afternoon and temperatures begin to fall. Several Pacific storm systems are lined up over the next week, bringing multiple rounds of rain, gusty winds, elevated surf, and eventually some mountain snow.
Our first system arrives late tonight into Friday morning, bringing scattered showers and the potential for a few thunderstorms along the coast. One thing I'm watching closely is the difference between our relatively warm ocean temperatures and the much cooler air moving overhead. This could help create enough instability for thunderstorms to develop, particularly over the coastal waters and nearby coastal communities. Any stronger cells could produce brief heavy downpours, lightning, gusty winds, and possibly small hail.
A second system quickly follows Friday evening into Saturday morning. This one looks to bring more widespread light to moderate rainfall across the coast, valleys, and mountains. Gusty westerly winds will also develop, particularly across the mountains and deserts.
A High Surf Advisory goes into effect Friday afternoon and continues through Sunday morning. West-northwest swells will build through Saturday, producing surf potentially reaching 7-9 feet. Dangerous rip currents and hazardous swimming conditions are expected, especially along west-facing beaches.
Sunday should provide a temporary break before another Pacific storm arrives Monday into Tuesday. This system could bring another round of widespread beneficial rainfall, gusty winds, and noticeably cooler temperatures. Snow levels will also begin dropping as colder air moves into the region, bringing the possibility of snow over our highest mountain elevations.
Yet another Pacific trough could impact Southern California around next Thursday or Friday. Confidence in the exact timing and strength remains lower this far out, but the overall pattern continues to favor unsettled conditions.
Temperatures will also take a noticeable tumble as we head into next week, with highs potentially running 5-10 degrees below average. #Socalwx #Sandeigowx #Imperialcountywx #Brawley #Elcentro #Julian #Pinevalley #Oceanside
