Las Vegas is starting Friday under clear skies and temperatures near 90 degrees, but the brief morning break will vanish quickly. The valley is headed for a high around 108, with an Extreme Heat Warning continuing through Sunday evening and little relief after dark.
Friday will stay sunny for most of the day, according to the National Weather Service in Las Vegas. A slight chance of showers and thunderstorms arrives between roughly 2 p.m. and 4 p.m., while southeast winds increase to 2 to 9 mph with gusts up to 18 mph.
Storm Chance Arrives During Peak Heat
Any thunderstorms are more likely to develop over higher terrain, though a few could drift toward nearby valleys. Storms that form may bring brief heavy rain and sudden gusty winds, even as the broader Las Vegas forecast remains mostly sunny and dry.
Triple-Digit Heat Holds Through Next Week
Saturday and Sunday will both reach about 108 degrees, with overnight lows near 87. The heat eases only slightly Monday, when the high is forecast near 106, before temperatures climb to 107 Tuesday, 109 Wednesday and 108 Thursday.
The Extreme Heat Warning covers the Las Vegas Valley through 8 p.m. Sunday, when heat-related illness risk is expected to remain elevated. Residents should drink plenty of fluids, use air conditioning, limit strenuous outdoor activity to early morning or evening, and check on relatives and neighbors.
Children and pets should never be left in unattended vehicles, where temperatures can become lethal within minutes. Anyone showing signs of heat stroke should be moved to a cool place and treated as an emergency by calling 911.
