Coastal Marine Layer To Bring Temecula Valley Relief From The Heat
While parts of Riverside County bake under 110-degree temperatures, the marine layer will keep Southwest Riverside County near or below 90.
RIVERSIDE, CA — An excessive heat warning remained in place Sunday for parts of the Inland Empire, where temperatures in the neighborhood of 110 degrees were expected in the Coachella Valley and the San Gorgonio Pass near Banning.
The excessive heat warning took effect at 10 a.m. Thursday and will continue until 8 p.m. Sunday, according to the National Weather Service.
"High pressure will continue to strengthen into the weekend," the NWS said. "Extreme heat will significantly increase the potential for heat-related illnesses, particularly for those working or participating in outdoor activities."

Air Quality in the region is also expected to remain poor going into the workweek, according to AccuWeather.
"The air has reached a high level of pollution and is unhealthy for sensitive groups," AccuWeather warned. "Reduce time spent outside if you are feeling symptoms such as difficulty breathing or throat irritation."
Meteorologists said clear skies and light winds will accompany the soaring mercury, with little relief until early this 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 next weekend.
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.
People were also urged to keep their animals out of the sun, make sure they access to clean drinking water and never leave pets in an unattended vehicle.
