Blistering triple-digit heat will continue to grip most of Riverside County through the weekend and beyond, with temperatures only expected to dip a few degrees mid-week.
According to the National Weather Service, the heat wave is due to a high pressure system moving to the west that will be centered over Southern California through the weekend.
This will cause inland temperatures to rise, although no thunderstorm activity is expected.
High temperatures Saturday were expected to reach 101 degrees in Riverside, 114 in Palm Springs, 102 in Banning and 97 in Temecula.
The region is not expected to fare much better on Sunday, with highs forecast between the high 90s and the low 110s.
Conditions will begin cooling on Monday, but thunderstorms could be possible in the mountains starting Tuesday as monsoonal moisture returns to the region, forecasters said.
Cooling centers will be open daily during the heat wave, providing county residents who do not live in climate-controlled environments a free, cool space to relax until the evening hours.
