Cooler temperatures arriving this weekend in Southern California
A cooling trend should begin this week in Southern California, according to forecasters, bringing more relief to crews on the front lines of fires.
Temperatures have been dropping slightly over the last few days, but not as much as some officials hoped. Friday should be another hot one, with temperatures reaching the triple digits in some valley and mountain locations, according to the National Weather Service.
The weather service said the heat continues to be a health threat to the elderly, young children and the frail.
But an upper-level trough from the northwest is expected to bring "significant cooling to the region on Saturday and Sunday."
During the weekend, temperatures in the valleys are expected to drop to the high 80s and low 90s.
