Las Vegas is heading into a dangerously hot Sunday, with clear skies and a forecast high near 115 degrees. Temperatures were around 86 degrees early Sunday morning, but the valley is expected to heat up quickly as the day unfolds.
An Extreme Heat Warning remains in effect through 8 p.m. Sunday, August 2, as the National Weather Service in Las Vegas warns of hazardous conditions across the Mojave Desert. There is no rain in the forecast, and the combination of extreme heat and very dry air will make outdoor activity especially risky.
Afternoon Winds Pick Up
Winds will shift from light and northerly early Sunday to southerly and southwesterly later in the day. Gusts could reach about 28 mph, with the strongest winds expected during the afternoon while temperatures climb into the 110s.
Sunday night will offer little relief, with mostly clear skies and a low around 90 degrees. Southwest winds may continue into the evening, and the forecast calls for heat index values as high as 106.
Triple-Digit Heat Sticks Around Through Midweek
Monday and Tuesday are expected to reach 113 degrees, followed by another 113-degree high Wednesday. Overnight lows will remain close to 90, keeping homes, vehicles and outdoor surfaces dangerously warm well after sunset.
Thursday through Saturday will remain sunny and hot, with highs between 111 and 112 degrees. The broader forecast suggests temperatures may ease slightly later in the week, but meaningful relief is not expected right away.
A Small Chance Of Storms Arrives Later
Monsoon moisture could begin returning Thursday, bringing a few widely scattered thunderstorms to parts of southern Nevada later in the week. The day-by-day forecast still shows mostly sunny conditions and only a 2% to 3% chance of precipitation, so this is not shaping up as a widespread rain event.
Heat Safety Remains The Priority
Residents should drink plenty of fluids, stay in air conditioning when possible and postpone strenuous outdoor work until early morning or evening. Never leave children or pets in an unattended vehicle, where temperatures can become lethal within minutes.
People who need a cooler place to spend part of the day can check RTC Southern Nevada’s cooling-station information before heading out. Anyone showing signs of heat stroke should be moved to a cool location and treated as a medical emergency by calling 911.
