It may be April but a rise in temperatures is expected to make Monday and Tuesday feel more like July and August.
"Temperatures will be near record highs, especially in the afternoon hours," said NBC4 meteorologist Crystal Egger.
Temperatures are expected rise 10 to 20 degrees above normal.
"Seventy-two degrees is our average high this time of year," Egger said. "We're going to be shooting for 90s, especially in inland areas."
On Monday, temperatures will hover in the 80s in Los Angeles and Ventura counties. By Tuesday Ontario, Riverside, and Palm Springs, among others, are expected to exceed 95 degrees.
After Tuesday, the weather will cool down to normal levels.
"We’ll be back to our sea breeze and that of course will give us a little more cloud cover and allow those temperatures to drop," Egger said.
This mini heat wave is a contrast to the cooler, wetter weather Southern Californians have experienced over the past few weeks. Rain and snow have been a welcome sight, especially amid long-term drought conditions.
