Remember last week, when monsoon storms surrounded the Las Vegas Valley but barely put a drop in many rain gauges?
Fortunately, there’s another opportunity to see some of the wet stuff this week.
Parts of the valley, including Henderson and Centennial Hills, saw a few light showers Tuesday night. Harry Reid International Airport recorded a trace of rain early Wednesday.
On Wednesday, parts of the south and southwest valleys. including Spring Valley, recorded at least 0.04 inches, according to gauges operated by the Regional Flood Control District.
“We’re returning to an active pattern,” said Matt Woods of the National Weather Service. “This is a pretty similar situation to last week.”
There’s at least a 20 percent chance of rain every day this week, he said. But during monsoon season, it can be “really tricky” to predict when it will rain (if at all) and how widespread it will be. It depends on several factors, including cloud cover, which can thwart the development of storms.
Very dry monsoon season
The last time the airport saw measurable rain was July 3, at the beginning of monsoon season, when it recorded .02 inches.
So far, this is the fourth-driest monsoon season on record, said Chris Outler of the weather service. The Las Vegas monsoon season runs from July 1 to Sept. 30.
The driest years are 2020 and 1944 (tied with a trace) and 2010 (0.01).
So far in 2025, the airport has seen 2.05 inches of rain (average is 2.27). A normal rainfall year in Las Vegas is 4.18 inches.
