BEAUMONT, CA —After record high temperatures were recorded in the Inland Empire this week, the heatwave was predicted to break, according to the National Weather Service. Temperatures across the board were expected to drop by at least 10 degrees in some areas, bringing welcome relief to mountain communities where many residents do not have air conditioning.

Borrego also had a record-high low temperature for the day, only cooling down to 86 degrees overnight. The last time Borrego saw that high of a minimum temperature was 2021.

A welcome cool-down across the Inland Empire was expected to bring some relief starting Thursday, the NWS said.

Riverside County valleys saw temperatures of up to 108 that day, according to the NWS.

On Thursday, in the Pass Area, temperatures would fall to 97 on Thursday, dropping into the high 80s through the weekend and climbing slightly to the low 90s by mid-next week.

Across Temecula Valley, the cities of Temecula, Murrieta and Lake Elsinore's temperatures were expected to drop to the low 90s before dropping to the mid-80s by the weekend and through next week. Low temperatures would fall to the low 60s and high 50s overnight, NWS forecasters predict.
