California – Marine clouds press low against the coastline this morning, muting sunrise colors and leaving streets damp and dim across coastal San Diego. Headlights glow through patchy fog, and the air feels heavy as winter officially begins.
According to the National Weather Service in San Diego, low clouds and fog linger through the morning, especially near the coast and inland valleys. Visibility may dip at times along I-5, I-8, and surface streets until clouds lift later. Afternoon conditions improve briefly, with filtered sunshine and highs in the upper 60s.
That break does not last long. Clouds thicken again Monday as moisture streams in from the Pacific. Temperatures remain mild, but the atmosphere turns unsettled. By Tuesday afternoon, showers begin developing, becoming more widespread and steady through Tuesday night. Rain chances climb above 60 percent, and roads could turn slick during the evening commute.
Meteorologists are also monitoring a slight chance of thunderstorms Tuesday night into Wednesday. While severe weather is not expected, heavier downpours could reduce visibility quickly and create ponding on highways. Drivers should prepare for slower travel during peak hours, especially near coastal routes and canyon roadways.
Wednesday remains wet. Showers continue throughout the day, with occasional heavier bursts possible. Conditions may deteriorate again Wednesday night, setting the stage for continued rain into Christmas Day. Holiday travelers should expect wet pavement, longer drive times, and limited drying windows.
No snow or cold snap is expected at lower elevations, but higher terrain east of San Diego could see cooler, unsettled conditions. For now, winter’s arrival comes with clouds and rain rather than cold.
Plan extra travel time beginning Tuesday, check wiper blades, and avoid flooded roadways. Winter is settling in along the coast. Are you seeing fog or drizzle where you are this morning?
