Dangerously hot conditions are expected with high temperatures from 106 to 114 degrees in the deserts, forecasters said. High temperatures are expected in the mid 90s to 104 degrees in the valleys.

"Hot conditions are expected for inland areas into early next week. Influence from the marine layer will help moderate temperatures closer to the coast," NWS San Diego forecasters wrote Thursday. "The marine layer will deepen into Friday, with low clouds reaching into portions of the western valleys. A gradual cooling trend is expected for much of next week."

Extreme heat will significantly increase the potential for heat-related illness, according to the NWS.
