“Strong upper level high pressure will bring excessively hot temperatures to the interior valleys, mountains and deserts through early next week, with above normal
temperatures most everywhere away from the coast,” according to the NWS.

Forecasters said humidity levels could drop in the mountains and interior areas. And gusting winds are likely in the afternoons, particularly in the Antelope Valley.

“As a result, there will continue to be elevated fire weather conditions in the afternoons across the drier and windier locations,” according to the NWS.
