High temperatures in the triple digits are expected in the Antelope Valley Thursday, prompting the National Weather Service to issue a excessive heat warning, but a cooling trend is forecast to start Friday.
The area near the western range of the San Gabriel Mountains will be under a heat advisory Thursday. But cooler temperatures are on the horizon for the weekend.
The warming trend began Tuesday afternoon, with conditions "turning significantly warmer away from the coast," according to the National Weather Service.
"A hot air mass will remain in place across the interior valleys for much of this week, with temperatures well above normal for this time of year," forecasters said. "Closer to the coast, the warming trend will be moderated due to persistent night through morning low clouds and fog and a moderate to strong onshore flow."
The warmest temperatures are anticipated in the Antelope Valley through Thursday, according to the NWS. The high in the Antelope Valley was expected to reach 107.
An excessive heat warning will be in place in the Antelope Valley and Antelope Valley foothills until 8 p.m. Thursday, noting that temperatures are expected to be between 98 and 107 degrees, accompanied by warm overnight low temperatures.
Forecasters issued their standard warnings for excessive heat, reminding people to drink plenty of liquids, stay indoors as much as possible and avoid leaving children or pets in vehicles.
"Take extra precautions when outside. Wear lightweight and loose fitting clothing. Try to limit strenuous activities to early morning or evening. Take action when you see symptoms of heat exhaustion and heat stroke," forecasters said.
