It’s going to be another weekend of extreme heat in Las Vegas

You may have to wait until September, or October, to enjoy a weekend free of big, summertime heat in Las Vegas.

Southern Nevada remains under an extreme heat warning until 8 p.m. Sunday. The forecast high for Saturday and Sunday is 107 degrees. The normal high for mid-to-late August is 103. Despite the warning, the valley is not expected to break any daytime heat records.

Harry Reid International Airport reached 108 degrees Friday, three degrees short of the 2020 record, said Brayden Murdock, a meteorologist at the National Weather Service office in Las Vegas.

Murdoch said there’s a 10 percent chance of rain for the valley this weekend. He said the higher terrain around Las Vegas, including the Spring Mountains and the Sheep Range, have the best opportunities of seeing a few showers.

This week’s extreme heat warning is the third in the past month. The summer’s first extreme heat warning lasted from July 23 through July 27. The second started July 30 and was extended several times, finally expiring Aug. 9.

More rain at Reid

Early Friday morning, the weather service reported that parts of the central valley were hit by a stray thunderstorm. In a post on X, the service said “a thunderstorm formed right over (our) office! We saw a bolt of lightning and heard thunder.”

The agency said the storm dropped 0.07 inches of rain at Reid and 0.12 inches at a rainfall gauge just west of the airport.

The airport has recorded 0.18 inches of rain this month, its wettest month since February (0.35). The August average is 0.32. Reid has registered 0.69 inches of precipitation so far in 2026. The average through mid-August is 2.64. In 2025, the airport had seen 2.05 inches through mid-August.
