This not a misprint. There is a chance of rain for Las Vegas this week.
“Modest monsoonal moisture” is moving into Southern Nevada starting today and will last through Thursday, the National Weather Service said in a post on X.
“This is our first taste of a monsoonal pattern,” said Ashley Nickerson of the National Weather Service. She said a “nice southerly flow” from the Baja Peninsula is contributing to the increased chances of showers and thunderstorms.
Daily rain breakdown
Today: The best chances will happen after 7 p.m., said Nickerson, who explained that the air surface is so dry, rain will struggle to reach the ground, called the “virga effect.” She said there could be lightning with no rain and sudden gusty winds. The forecast high is 109 degrees, which would match June 16 as the hottest day of 2026. The average high for late June is 101.
Wednesday: There is a 30 percent chance of storms, with the best chances arriving in the late morning and into the afternoon, Nickerson said. The forecast high is 107. Rain chances for the Spring Mountains are less than 50 percent. She said no storm/flood advisories are expected.
Thursday: Rain chances will diminish through the day; the forecast high is 107. “It looks dry,” Nickerson said.
In the Southwest, monsoon season started June 15 but typically the season doesn’t become active for Southern Nevada until July 1. The season runs through September.
Harry Reid International Airport, the official climate site, has not seen any measurable rain since Feb. 19, when it recorded .08 inches. It’s rainless streak has topped 120 days, Nickerson said.
Cooling stations activated
Clark County said it has activated cooling stations at community centers, libraries and other buildings across the valley through Sunday.
The cooling stations’ hours will vary depending on the location, the county said. The stations will include several locations in Las Vegas, North Las Vegas, and Henderson.
The stations are open to anyone in need of respite from the heat, the county said. Additional information can be found at the Southern Nevada Homelessness Continuum of Care’s website at helphopehome.org/get-help/, the county said.
