Las Vegas woke to clear skies Tuesday morning, but the valley is headed for a dangerous stretch of heat, with afternoon temperatures reaching 108 degrees. Overnight lows will remain in the mid-80s, offering little relief before the next day’s furnace turns on.
An Extreme Heat Warning is in effect across southern Nevada from Tuesday morning through 8 p.m. Friday, according to the National Weather Service. The warning calls for highs between 107 and 110 degrees in many desert valleys, with even hotter readings possible in Death Valley and the lower Colorado River Valley.
Wednesday And Thursday Bring The Peak Heat
Wednesday and Thursday are expected to be the hottest days in Las Vegas, each with a high near 109 degrees under mostly sunny or sunny skies. South to southeast winds will generally run from 2 to 10 mph, with occasional gusts reaching 20 mph Tuesday afternoon.
Tuesday night will stay partly cloudy with a low around 86 degrees, while Wednesday night could dip only to 88. Those unusually warm nights matter because the body gets less time to cool down between hot afternoons.
Monsoon Storms Return Late This Week
A small chance of isolated showers and thunderstorms arrives late Thursday night, followed by scattered showers and thunderstorms Friday before 5 p.m. Rain chances remain limited but could continue into the weekend, when highs ease slightly to about 105 or 106 degrees.
Storms are more likely across higher terrain in Southern Nevada and toward Mohave County, but any cell could produce a brief heavy downpour, gusty winds, lightning or localized flash flooding. Saturday through Monday bring only slight storm chances, with mostly sunny skies still dominating the forecast.
Heat Safety Remains The Main Concern
Drink water regularly, stay in air conditioning when possible and move strenuous outdoor work to early morning or evening. Las Vegas officials also emphasize checking on neighbors and relatives, while reminding residents that children and pets can be overcome quickly inside parked vehicles; additional guidance is available from the City of Las Vegas.
Never leave a child or pet unattended in a vehicle, even briefly. Anyone showing signs of heat stroke should be moved to a cool place and treated as a medical emergency by calling 911.
