More than 25 major cities tied or broke record-high temperatures Saturday, during a dangerous heatwave that enveloped much of the Southwestern United States over the weekend. Approximately 53 million people are still under excessive heat warnings as extreme temperatures begin to shift east.

California's Death Valley, which holds the world record for hottest recorded temperature (134 degrees) set over a century ago, was the hottest place in the country Saturday at 122 degrees. Palm Springs and Phoenix, Ariz., tied for second place Saturday at 114, both cities matching previous record high temps.

Robert Oravec, a lead forecaster with the National Weather Service, said the heat will move away from the Southwest beginning Monday, traveling east towards the Mississippi River Valley over the coming days.

'It'll stretch eventually by mid-week from the Great Lakes to the Southern Plains eastward. Not too hot in the northeast yet, more of an average," Oravec said. "It's a very typical heatwave pattern set up in the Southwest and spreading now into the plains. You're almost into mid-June now, so it's not uncommon to see weather patterns that support a heatwave."
