Brutal Heat Continues Tuesday Before The Southland Cools Down — For Now

LOS ANGELES, CA — Temperatures are expected to get up to 105 degrees in part of the Southland Thursday before the sweltering weather gives way to a cooling trend later this week, according to the National Weather Service.

An excessive heat warning is in effect until 8 p.m. in the Antelope Valley and foothills, where temperatures could reach 105 degrees. In the western San Gabriel Mountains and 14 Freeway corridor, a less severe heat advisory is in effect until 8 p.m. due to forecasted temperatures of up to 100 degrees.

A heat advisory issued by the Los Angeles County Department of Public Health will remain in effect through Tuesday for the Antelope Valley.

"On hot days, it's important for everyone to both take care of themselves and check on others, especially those who have a higher chance of getting ill due to the heat. Some of them include children, the elderly, those with health conditions, pregnant people, those living alone, and pets," Dr. Muntu Davis, Los Angeles County Health Officer, said in a statement. "Hot days can be dangerous for anyone, so it's crucial to stay cool and hydrated.

It's expected to be cooler along the coast and in the Valleys Tuesday — by about 4 to 8 degrees compared to Monday — though temperatures are expected to hold steady from Monday farther inland.

Highs were forecast to be in the mid 80s in downtown Los Angeles, the low 90s in the San Gabriel Valley and the mid 90s in the San Fernando and Santa Clarita valleys.

The gradual cooling is expected to continue through the middle of the week. By Thursday the coast and valleys will be one to three degrees below normal, with valley highs between 80 and 90 degrees.

By Friday, some areas will see temperatures three to six degrees below normal and the marine layer may fail to clear above some beaches for the entire day, according to the NWS.

The trend could reverse by Saturday, when a high pressure system could raise temperatures by one to three degrees Saturday and two to five degrees on Sunday, according to the NWS.

A Smog Advisory is in effect for most non-coastal areas of Los Angeles County and much of Riverside County until 7 p.m. Tuesday. The South Coast Air Quality Management District said the extreme heat will likely lead to unhealthy or worse air quality conditions in much of the area.

The AQMD urged residents to check air quality levels and limit outdoor activities, limit the use of gasoline-powered lawn and garden equipment until evening hours and conserve electricity.

It comes after a weekend of sweltering temperatures. The daily high temperature record at Camarillo Airport was broken two days in a row, on Monday and Sunday, were highs of 89 broke records set in 1931, according to the NWS.
