It’s Spring--So That Has to Mean Foggy Mornings, Clear Afternoons

Typical spring weather is forecast for Southern California through the weekend.

Morning fog and low clouds are expected to give way to clear skies and warmer temperatures this afternoon, but a scattering of afternoon and evening thundershowers is expected in the mountains and deserts, beginning Saturday and continuing into next week.

“A high-pressure system that kept conditions relatively dry Thursday is weakening and beginning to drift away to the north,” said Matt Sullivan, meteorologist-spokesman for Earth Environment Service, a private forecasting firm based in San Francisco.

“Tropical moisture is moving into Southern California from the south. This is an unstable situation and should bring on more thundershowers with no difficulty at all.”

High at Los Angeles Civic Center Thursday was 75, with relative humidity ranging from 55% to 84% during the day. And the National Weather Service said it should be about five degrees warmer this afternoon, rising to 82 or 83 Saturday and Sunday.

Beach weather, meanwhile, is expected to include fog and drizzle this morning, with partial clearing during the afternoon, highs from the upper 60s to the low 70s and an afternoon sea breeze rising to 15 m.p.h., with surf breaking at three feet in most places and water temperature only a few degrees cooler than the air.
