Temperatures Are Expected to Soar This Week

As Southern California gets its first real taste of summer, temperatures this week could reach 100 in inland Orange County and 105 in the San Fernando, San Gabriel and Antelope valleys. There’s also a chance of a few thundershowers in the San Gabriel and San Bernardino mountains.

Winds circulating clockwise around high pressure over the Rockies are pulling warm, moist air in from northern Mexico, the National Weather Service said. Temperatures in the upper 90s and low 100s are expected in inland Orange and Los Angeles counties and western San Bernardino County, with only slight cooling over the weekend.

Those circulating winds will reach the valleys, but they won’t quite reach the coast, so temperatures at the beaches, downtown Los Angeles and much of Orange County should stay comfortably near normal, said Dan Keeton, a weather service meteorologist.

Highs in coastal Orange and Los Angeles counties are forecast mostly in the 70s and 80s this week, peaking in the upper 80s near Santa Ana and near 90 at the Los Angeles Civic Center. In inland Orange County, however, temperatures could reach well into the 90s.

Forecasters said there’s a slight chance of afternoon and evening thundershowers in the mountains through Friday.
