100-degree weather returns for Fourth of July weekend in Las Vegas

Guess what’s back? 100-degree temperatures. And just in time for the long Independence Day weekend in Las Vegas.

The high at Harry Reid International Airport on Thursday was 100 degrees, said meteorologist Julie Phillipson of the National Weather Service. It was the first time Reid has hit the century mark since June 26, when it saw 103.

The forecast high for Friday is 102; Saturday is 105 and Sunday is 105. The average high for early July is 104.

“Temperatures will continue to gradually increase through the end of the week with seasonal temperatures returning over the holiday weekend,” the NWS said in a post on X. “Dry conditions will continue into next week, with southwesterly breezes in the afternoons.”

Phillipson said the valley will continue to warm up next week and may see its first 110-degree day of the year Thursday. But there are no chances of monsoon rain for at least the next week, Phillipson said.

“Nothing substantial” is on the horizon, she said. The average rainfall for July is 0.38 inches.

On June 23, Reid recorded 0.02 inches of rain, breaking a rainless streak of 124 days. It was the only rainfall of the month.
