An early summer heat wave continues to bake inland areas of San Diego County, setting records and prompting a statewide power alert.

Wednesday wasn’t quite as intense as Tuesday, but temperatures are expected to rise and peak on Thursday.

Campo hit a record 107 on Wednesday, and it was hot throughout the region. Borrego Springs recorded 109, Julian hit 97, Valley Center was 95, Ramona 94 and Escondido 93.

“Strong high pressure over the Southwest will bring hot days and warm nights through the weekend. A coastal eddy will bring some relief from the heat for coastal and western valley areas,” according to the National Weather Service.

Highs on Thursday are forecast to be 74 to 79 near the coast, 81 to 86 inland, 85 to 90 in the western valleys, 94 to 99 near the foothills, 95 to 105 in the mountains and 116 to 121 in the deserts.

Because of the heat, the California Independent System Operator has called for voluntary power conservation from 5 p.m. to 10 p.m. on Thursday.

The sweltering weather is expected to last through the weekend, and an excessive-heat warning remains in effect through 9 p.m. Friday for the western valleys, 9 p.m. Saturday for the mountains and 9 p.m. Sunday for the deserts.
