High pressure aloft and offshore flow at the surface will bring warm weather Sunday but clouds will thicken Sunday evening into Monday as a Pacific disturbance spreads high-level moisture over the region, San Diego forecasters said.
At 8:32 a.m., the National Weather Service in San Diego issued the latest forecast that said scattered, light showers or sprinkles will be possible through Tuesday night as the marine layer rebuilds inland. High pressure aloft and weak offshore flow will translate to dry and warmer weather wrapping up the week.
”Skies were mostly clear Sunday morning over Southern California, with a few wisps of high clouds edging in from the west,” forecasters said. ”Temperatures were a bit milder overall Sunday morning, but low, sheltered spots once again fell into the 30s.”
Afternoon temperatures could climb into the 70s at lower elevations, which is some five degrees above average.
Onshore flow will develop over coastal areas later Sunday and will drag some low marine air inland, which could result in some patchy fog. But due to the increasing high clouds, it is not expected to be widespread.
At the beaches, calm conditions through the afternoon are expected with patchy fog possible Sunday evening.
An incoming northwest swell will generate wave heights of 6-8 feet Wednesday into Thursday morning. Wave heights will be highest south of San Clemente Island. Otherwise, no hazardous marine conditions are expected through Thursday.
