A ridge of high pressure is expected to bring temperatures to a sizzle this week in the Sacramento region and throughout the state.
Temperatures on Sunday are forecast to reach the low 90s, the beginning of a small heat wave. The National Weather Service is predicting triple-digit temperatures, with Tuesday bringing a high to Sacramento of 108 degrees.
“We’re a little bit above average, but no records,” said Courtney Obergfell, a weather service forecaster in Sacramento.
The heat will back off to a high of 100 degrees on Thursday and continue to retreat in time for relatively cooler weather on the Fourth of July. The weather service is calling for a high of 94 degrees on the holiday.
Farther north, though, high temperatures are expected to be dramatic. In Redding, a high of 113 degrees is predicted Tuesday, followed by 111 on Wednesday and 110 Thursday. A high of 104 degrees is expected for the Fourth of July at the far northern end of the Sacramento Valley.
