Las Vegas was already near 91 degrees under clear skies before sunrise Wednesday, and the city is headed for a high near 110 by late afternoon. The hotter story is still ahead: a long, dangerous stretch is expected to peak at 117 degrees Saturday, with overnight temperatures barely budging.
The National Weather Service has issued an Extreme Heat Warning from 10 a.m. Thursday, July 30, through 8 p.m. Sunday, Aug. 2. Highs are expected to reach 111 Thursday, 113 Friday, 117 Saturday and 116 Sunday, while lows stay in the upper 80s to low 90s. The warning covers southern Nevada and says the risk of heat-related illness will rise significantly.
Weekend Heat Looks Worst
Forecast highs remain 115 degrees Monday and 115 degrees Tuesday, so relief is not expected immediately after the warning ends. The agency’s climate outlook puts Las Vegas records in jeopardy from Thursday through Sunday, including a 115-degree record for Friday and a 116-degree mark for Saturday.
The nights will be unusually tough. Wednesday night is forecast to bottom out around 86 degrees, followed by lows near 87 Thursday night, 89 Friday night and 92 Saturday night; even Sunday through Tuesday nights stay near 90 degrees or higher. That leaves homes, cars and bodies with less time to cool down between scorching afternoons.
Windy, Dry And Almost Rain-Free
Wednesday stays sunny and dry, with south winds of 6 to 13 mph and gusts up to 21 mph. Rain chances are effectively zero in the Las Vegas forecast through Tuesday, although isolated storms remain possible in eastern Mohave County Wednesday afternoon.
Heat Safety Matters
Anyone spending time outdoors should drink plenty of water, use air conditioning or another cool indoor space, and move strenuous work to early morning or evening. Never leave children or pets in unattended vehicles, where temperatures can become lethal within minutes. Call 911 for suspected heat stroke, and check on neighbors and relatives who may be especially vulnerable to the heat.
