Las Vegas residents should brace for a sharp change as thunderstorms push into the valley Thursday evening, threatening travel and outdoor plans. Heavy rain and lightning could cause slowdowns on I-15 and local roads during peak evening hours.
According to the National Weather Service, a 50 percent chance of showers and thunderstorms begins late Thursday, continuing into Friday. Gusty winds may follow stronger storms, and brief downpours could reduce visibility across Clark County. Drivers should allow extra time, avoid flooded streets, and secure loose outdoor items before the system arrives.
Temperatures will dip slightly but remain warm. Highs Wednesday and Thursday will push into the upper 90s before cooler air arrives for the weekend. Friday stays unsettled, with more storms possible, but by Saturday, drier skies and sunshine return. Highs will hold in the low 90s, offering some relief after the heat.
Residents planning outdoor events Thursday night or Friday should prepare backup plans. Officials urge caution when traveling in storm conditions, as flash flooding can develop quickly in low-lying areas. Lightning will also pose risks for hikers and outdoor workers, especially near Red Rock Canyon.
While the weekend looks calmer, forecasters warn that more September storms could develop early next week. Stay updated with advisories as the system moves through.
