Southern California temperatures in 80s over Memorial Day weekend

A building high-pressure system and offshore winds should push temperatures well into the 80s this Memorial Day weekend.

Highs today are forecast to top out in the 70s, but the winds should shift offshore tonight and bring an extended warm spell to Southern California, which has seen below-normal temperatures and uncharacteristic drizzle this week.

Memorial Day should be sunny and clear, with highs ranging from about 80 degrees at the beaches to the mid 80s in the valleys. The deserts are expected to break into the 90s.

Forecasters expect prevailing southwesterly winds to back to the north late tonight and start blowing from the north at 15-25 mph, with stronger gusts, according to the National Weather Service.

The NWS issued high wind warnings for the mountains and high desert for tonight and tomorrow morning.

In addition to heating up the Los Angeles Basin due to compressional warming, the offshore winds should keep the marine layer well offshore.

The winds will eventually clock around to the northeast, and gusts below canyons and passes could hit 40 mph or more.

Saturday should be sunny and clear, with highs ranging from the upper 70s and low 80s near the coast to the mid and upper 80s inland and in the valleys, according to the NWS.

Sunday should be about the same, but the winds should relax some. The NWS predicts that the warm weather will continue at least through the middle of next week.
