Hot weather will continue Friday throughout Riverside County, but slightly cooler temperatures are expected to arrive this weekend, according to the National Weather Service.

An excessive heat warning expired last night in the Riverside metropolitan area, the Riverside County mountains, the San Gorgonio Pass near Banning and the Coachella Valley.

The NWS urged residents to drink plenty of fluids, stay out of the sun and check on relatives and neighbors. Also, children, seniors and pets should be never be left unattended in a vehicle, with car interiors able to “reach lethal temperatures in a matter of minutes,” according to the NWS.

High temperatures Friday are forecast to reach 108 in the Coachella Valley, 109 in the San Gorgonio Pass near Banning, 106 in Riverside, and 100 in Idyllwild.

Thunderstorms will be possible Friday afternoon in the Riverside County mountains, forecasters said.

Highs in the Coachella Valley are expected to drop to 107 on Saturday, according to the NWS. High temperatures in the Riverside metropolitan area are forecast to remain in the triple digits throughout Friday.

Thursday’s high reached 95 in Idyllwild, beating out 93-degree record for an August 20, set in 1943, according to the NWS.

Over the weekend, leftover moisture from tropical storm Genevieve will likely create a cloud layer over much of Riverside. The cloud deck will likely minimize the heat, but will also bring thick humidity, according to forecasters.

Riverside County has 14 cooling centers available countywide with mandatory mask wearing and social distancing protocols in place. Among the 14 locations, five are in the Coachella Valley, two in the Banning Pass, one in Moreno Valley, one in Temecula and five in Riverside.
