Heavy clouds blanketing Southern California will give way to sunny skies, along with hot and dry conditions and an increased wildfire risk.
The National Weather Service said Wednesday that as the marine layer weakens, temperatures could spike into the 90s around Los Angeles and even top 100 in inland areas. The heat wave is expected to peak Friday.
Forecasters say humidity levels could drop as low as 6 percent. The dry conditions accompanied by gusty winds could bring elevated fire danger, especially in mountains and interior valleys.
Along the coast, a high surf advisory will be in effect until 10 p.m. Thursday, with surf topping 7 feet in some areas.
