Las Vegas Weather Forecast Extreme Heat Continues, Slight Cooldown by Friday

Southern Nevada is enduring an intense stretch of heat, with triple-digit temperatures expected to persist through Thursday evening. The National Weather Service has issued an Extreme Heat Warning, with highs reaching near 111°F on Wednesday and slightly easing to 108°F on Thursday. This extreme heat will continue to impact Las Vegas, Henderson, Boulder City, and nearby desert communities, including Lake Mead National Recreation Area, Pahrump, and Mesquite.

Heat-related illnesses can develop rapidly in these extreme conditions, especially for those without proper cooling or hydration. Residents are urged to limit strenuous outdoor activity to the early morning or evening hours, wear light clothing, and drink plenty of water throughout the day. The Occupational Safety and Health Administration (OSHA) recommends frequent rest breaks in shaded or air-conditioned areas for anyone working outdoors. It’s also critical to never leave pets or children unattended in vehicles, as interior temperatures can reach lethal levels within minutes.

While a slight cooling trend is expected by Friday, temperatures will still hover in the low 100s, with a chance of isolated thunderstorms later in the week.

Here’s the detailed five-day forecast for Las Vegas:

Wednesday: Sunny with midday haze. High 111°F, low 84°F.
Thursday: Sunny and hot. High 108°F, low 81°F.
Friday: 30% chance of storms after 11 a.m., high 104°F, low 80°F.
Saturday: Slight chance of storms after 11 a.m., high 102°F, low 79°F.
Sunday: Sunny, high 103°F, low 77°F.
