PALM DESERT, CA — A high-pressure system has settled over SoCal this week, keeping in super-heated weather conditions across western Riverside County, prompting an Extreme Heat Warning for the Coachella Valley and the San Gorgonio Pass near Banning, until 8 p.m. Friday. The National Weather Service recorded 117-degree temperatures in Palm Desert Wednesday afternoon, with little reprieve in sight.

A Heat Advisory was also in place for Riverside County and San Bernardino County mountains and valleys until 8 p.m. Friday, according to the National Weather Service.

The high pressure will remain firmly in place across the desert southwest through Thursday, which promises to be the hottest day of the week.

"Temperatures could reach 105 degrees in parts of the Inland Empire on Thursday, and 115 in the lower deserts," meteorologists said.

"Please take precautions to beat the heat, such as staying in air-conditioned places, taking breaks if having to work outside, and limiting outdoor recreation," meteorologists advised.

The hazy skies are still affected by the Gifford Fire burning in Santa Barbara County, they said.

The high will begin to weaken by Friday, which will ease temperatures by a few degrees, but remain warm. Low-level moisture will also be present as the high weakens Friday into Saturday so that higher humidity will be felt, especially across the lower deserts.

Does that mean a chance for monsoonal storms? Meteorologists say there is a chance for monsoon storms, starting at 5 to 10 percent Friday, and into the weekend in predominantly areas close to the mountains.
