The first heat wave of the season will build Thursday, sending some valley temperatures into the 90s and 100s.
The hot and dry conditions are expected to last through Saturday with temperatures several degrees above normal. Burbank is expected to reach a high of 94 Friday, well above the normal temperatures of 78 degrees.
By Friday, the humidity level will drop to between 6 and 12 percent in interior valleys and some mountain areas, and to the 15-25 percent range in coastal valleys, and possibly lower, depending on the marine layer.
"We don't have much in the way of clouds this morning," said NBC4 forecaster Crystal Egger.
At the same time, gusty west-to-north winds are expected in the afternoons and evenings in the mountains and interior valleys, leading to elevated fire danger.
Winds are not expected to be as strong along the coast and in nearby valleys.
Also along the coast, a high surf advisory will be in effect until 10 p.m. A less serious beach hazards statement will be in force in Orange county at the same time.
