“Extreme heat will significantly increase the potential for heat- related illnesses, particularly for those working or participating in outdoor activities,” according to the NWS.
As usual during heat waves, forecasters urged residents to drink plenty of fluids, seek out air conditioned spaces and check on vulnerable relatives and neighbors.
“High pressure will continue to strengthen into the weekend,” according to the NWS. “Warming for inland areas will continue into Friday and Saturday with high temperatures 10 to 15 degrees above average with the peak of the heat for the valleys, mountains, and deserts on Friday and Saturday.”
According to meteorologists, clear skies and light winds will accompany the soaring mercury, with little relief until the start of next week, when a trough of low pressure is slated to slide into the region.
Forecast models indicated that the Temecula Valley will benefit from coastal marine layers most of the week, with highs remaining at or just below 90 and lows around 60 going into the weekend.
