Days after Southern California saw the first significant rain in nearly a year, the region fell back into summer-like winter with a heat wave that set new records.

Among the places that set new high temperature records for the day: Los Angeles International Airport (86 degrees) and Long Beach (88). Lake Forest in Orange County was the hottest place in the United States on Saturday, registering a high of 90, according to the National Weather Services.

Highs will hit the 70s and 80s Sunday. Light rain is possible Thursday and Friday.
