Heat Wave Continues Across Riverside County

RIVERSIDE COUNTY, CA — More unseasonably warm weather is in the forecast for Riverside County Friday — particularly in the Coachella Valley, where temperatures could reach 107 degrees, the National Weather Service said.

The weather service also called for temperatures from 94 to 99 Friday in the Riverside County valleys and Inland Empire, and 85 to 95 in the Riverside mountains before a cooling trend over the weekend.

More moderate high temps of 82 to 87 in the valleys and IE and 75 to 85 in the mountains are expected for Saturday, according to forecasters.

But the Coachella Valley should feel more scorching temperatures over the weekend, with highs ranging from 99 to 104 on Saturday and 91 to 96 on Sunday.

"A ridge of high pressure setting up over California will strengthen through Friday," the NWS said. "That ridge will result in well-above-average temperatures west of the mountains and High Desert through Friday, and through Saturday in the low deserts."

Lows will generally be in the 50s for deserts and valleys.

According to the NWS, the high pressure system fueling the warm-up will slide across the Great Basin in Nevada and Utah, replacing the trough of low pressure that dominated the region at the start of the week and kept the mercury on the cool side.

Forecasters predicted a return to seasonal norms by the start of next week.

No precipitation is in the forecast.
