The big summer heat is gone for now, but the monsoon moisture has taken its place.
A few thunderstorms soaked parts of the Las Vegas Valley on Wednesday afternoon, including the east side around Nellis Air Force Base and Centennial Hills.
However, Harry Reid International Airport only recorded a trace of rain. The airport, which reached 101 degrees, experienced flight delays of up to 45 minutes in the afternoon, according to the FAA.
The airport has not seen measurable precipitation since June 23, when it recorded 0.02 inches of rain, breaking a rainless streak of 124 days. It was the only rainfall that month.
Last month, Reid recorded a trace of rain July 19. The average August rainfall in Las Vegas is 0.32 inches. In August 2025, Reid only saw a trace.
Here are some rainfall totals reported by the Regional Flood Control District:
— Nellis AFB: 0.78 inches
— East Las Vegas: 0.51
— Centennial Hills: 0.31
— Henderson (near Burkholder Middle School): 0.24
— UNLV: 0.12
— North Las Vegas: 0.08
Cooldown coming
The forecast high for Las Vegas is 97 degrees Thursday, the first time the valley will see temperatures below 100 since July 17, when it saw 97, the “coolest” day of the month.
Jenn Soulat of the weather service said a low-pressure system coming from the Pacific Ocean will cool the valley off through the weekend as temperatures will stay below the normal of 104.
There is a 15 percent chance of rain for Thursday, which increases to 50 percent Friday, Soulat said.
