Cloudy skies helped keep temperatures in the Sacramento area a little lower than expected for most of Wednesday, but late afternoon clearing boosted highs into the triple digits in several areas.
Downtown Sacramento topped out at 101 degrees and Sacramento Executive Airport at 99 degrees, said Karl Swanberg, a meteorologist with the National Weather Service.
In other communities around the region, highs included 104 degrees in Roseville, 103 in Carmichael and El Dorado Hills, 101 in Davis and 100 in Elk Grove.
Further north, Redding reached 111 degrees, and an excessive heat warning remains in effect for areas from Marysville to the Oregon border until 8 a.m. Friday.
Slightly cooler temperatures are forecast for the Sacramento area, with a high of 97 degrees expected Thursday and 94 degrees on Friday.
In the Sierra, the forecast calls for a chance of scattered showers and thunderstorms in the afternoon an evenings through the weekend.
