“It’s a slam dunk to beat that today,” weather service meteorologist Chris Outler said. “Monday and Tuesday will be the warmest days of the year, but the temperatures won’t drop much all week.”

Officially, an excessive heat warning/advisory for the region expires at 10 p.m. Wednesday, but temperatures of 105-110 will persist through the weekend and probably longer, Outler said.

The official high Sunday was 113, tying a mark set in 1939.

91 at 4:20 a.m.

Overnight, McCarran International Airport had a reading of 91 at 4:20 a.m., providing a warm start to Monday. By 9 a.m., the temperature had climbed to 98 after bottoming out at 89 just before 6 a.m.

Hottest Death Valley reading in 107 years

A 3:41 p.m. Sunday high of 130 degrees at Furnace Creek in Death Valley National Park may have been the hottest reading on the planet since July 1913. The reading will have to be verified by a Climate Extremes Committee of the United Nations’ World Meteorological Organization.

According to the organization, the official keeper and verifier of global climate extremes, the highest air temperature recorded anywhere in the world is 134 degrees at Death Valley’s Greenland Ranch on July 10, 1913.

Change in pattern

Relief could be a week away.

“Early next week we might get some better pushes of moisture into the area,” Outler said. “It’s a pattern change that has some promise.”
