Downtown Sacramento hit a high of 107 degrees Sunday, just one degree away from matching an 1894 record.
The late summer heat wave is being caused by an area of strong high pressure that is creating sinking air over California, said National Weather Service Meteorologist Chris Hintz. “And when air sinks, it heats up.”
On Monday, Sacramento is expected to hit 108 degrees. Redding's high temperature is forecast to be 111.
Redding broke heat records on Sunday, recording 111 degrees. That topped the old record in 1988 by one degree. At 106 degrees, Modesto also broke a record Sunday set in 1944, when temperatures reached 104.
Triple-digit highs are forecast throughTuesday, buttemperatures will dip to 98 degrees Wednesday, according to the weather service. But the heat will continue through the weekend, with highs expected to be up to 104 degrees.
“We may see a cooling trend early next week,” Hintz said.
