Las Vegas is starting Monday clear and already around 82 degrees, with temperatures set to race toward 104 by afternoon. The bigger concern arrives Tuesday, when a dangerous stretch of triple-digit heat begins across the valley and overnight temperatures offer little relief.
Heat Peaks Wednesday And Thursday
The National Weather Service has issued an Extreme Heat Warning for Southern Nevada from 10 a.m. Tuesday through 8 p.m. Friday. Las Vegas is forecast to reach 107 degrees Tuesday, then 108 degrees Wednesday and Thursday, while overnight lows remain in the upper 80s.
The warning covers a broader desert region where temperatures could climb even higher, but the local concern is the combination of intense afternoon heat and unusually warm mornings. The National Weather Service says the hottest period should arrive Wednesday and Thursday, when overnight lows may approach daily records.
Storm Chances Return Late In The Week
Monday and Tuesday will stay sunny, with southeast winds generally below 10 mph Monday and gusts up to 20 mph possible Tuesday. A few showers or thunderstorms become possible Thursday afternoon, with slight chances continuing Friday through Sunday as monsoon moisture returns.
Anyone working or exercising outside should shift strenuous activity to early morning or evening, drink plenty of fluids and take frequent breaks in air conditioning or shade. The city advises residents without working air conditioning to seek cooled public spaces such as libraries, malls or community centers, and to check on neighbors who may be especially vulnerable; children and pets should never be left in a parked vehicle, according to Las Vegas officials.
