Las Vegas, Nevada – The pavement is already radiating heat across the Las Vegas Valley, and temperatures will climb rapidly through midday. Triple-digit heat will dominate the afternoon, while only a slight chance of isolated thunderstorms offers limited relief before another hotter stretch arrives later this week.
According to the National Weather Service in Las Vegas, Monday will be sunny and hot with a high near 106 degrees. There is a 10 percent chance of showers and thunderstorms before 8 a.m. and again after 2 p.m., but most neighborhoods will remain dry. Light morning winds will increase to around 10 mph during the afternoon, adding little cooling.
The hottest part of the day will arrive between 2 p.m. and 6 p.m., when exposed pavement, parking lots, and vehicle interiors become especially dangerous. Anyone traveling along Interstate 15, Interstate 11, U.S. 95, or the Las Vegas Strip corridor should carry extra water, avoid extended outdoor activity, and never leave children or pets inside parked vehicles.
While storm chances remain low today, any thunderstorm that develops could bring brief gusty winds, lightning, and localized blowing dust. Across the Southwest, monsoonal moisture continues to circulate through the region, keeping isolated thunderstorm chances in the picture during the week without ending the heat.
Tuesday brings another 106-degree afternoon under mostly sunny skies. By Wednesday, temperatures climb to 107 degrees, followed by an even hotter 109 degrees Thursday. Only isolated storm chances appear later in the week, so the primary weather story remains prolonged summer heat.
