100-Degree Days Make a Return to the Valley

The mini-heat wave that roasted the San Fernando Valley on Sunday will stick around for another day or two before temperatures drop into the 90s, weather forecasters said.

No records were set, but the mercury climbed into the triple digits throughout the Valley on Sunday, with Chatsworth and Burbank topping the charts at 108.

Van Nuys wasn’t too far behind, at 104 degrees, and Woodland Hills sweltered through a high of 102, according to the National Weather Service in Oxnard. Death Valley beat everyone in California at 122. The Civic Center in downtown Los Angeles was 90 degrees.

“It’s going to be like this for the next two days, pretty warm,” said Jeff House, meteorologist with WeatherData Inc., which provides weather and forecasting information to The Times. “By Wednesday, it should start going down for you.”

Forecasters said a massive upper-level, high-pressure system hovering over the Southeast is responsible for the blast of heat. Although weaker, it’s similar to the weather system that brought record temperatures to the Valley more than a week ago.

“A trough off of the coast will turn winds onshore, causing a cool-down,” House said. “Basically, we expect the Valley will receive more of the cooler air coming in from the ocean instead of the hotter stuff from the east.”

Morning lows are expected to range from the mid-to-upper 60s through Friday, House said.
