Sacramento's record heat spiked at 108 degrees around 6:10 this evening - but the spike won't last long.
Forecasters with the National Weather Service said the brief heat wave will start to ease rapidly this evening, with breezes from the Delta providing a natural air conditioner. The predicted high for Sunday in downtown Sacramento is 89 degrees.
"It's going to be pretty cold," forecaster Drew Peterson said of the evening conditions.
The blistering heat today was unprecedented for the date. Peterson said "pretty much everywhere you can think of broke a record."
That included a high of 112 in Red Bluff, 111 in Redding and 110 degrees in both Chico and Marysville. The tiny Capay Valley hamlet of Brooks topped out at 112 degrees.
Relief from the warm conditions is expected to last at least through next weekend. Peterson said the long-range forecasts call for mid- to upper-80s through the week, with the possibility of a 90-degree reading next weekend.
"I don't see another 100-degree day coming any time soon," he said.
The huge drop in temperature isn't highly unusual, given that a storm system is entering the area on Sunday, Peterson said. There's a decent chance for thunderstorms in the Sierra and through the Valley, with the possibility of thunder echoing through downtown Sacramento.
