Four people died in Las Vegas of heat-related causes.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Las Vegas, NV wrote its last area forecast discussion before the first event at Aug 1, 9:00 PM PST, 3 hours earlier. Its key messages:
Area Forecast Discussion National Weather Service Las Vegas NV 1000 PM PDT Fri Aug 1 2025 .KEY MESSAGES... * Mostly dry conditions and seasonal temperatures continue through the weekend and into the start of next week. * Potential for a monsoonal moisture surge midweek, with above- normal temperatures mid-to-late week. && .DISCUSSION...through Friday. On a surprising note- there has been a surge in moisture in western Arizona. Dewpoints have rose into the 50s to near 60F and PWATs have gone from 0.30in yesterday to 0.50-0.75in today. This moisture combined with modest instability and a weak upper level jet streak has allowed for isolated thunderstorms to develop in northeast Mohave County. Very isolated thunderstorm activity is not out of the question in eastern Mohave County through sunset, but confidence is low if and where they could develop as models seem to be lagging behind current conditions. If thunderstorms do develop, they may contain brief moderate to heavy rain, lightning, and wind gusts to 30 MPH. If anything develops, it will end quickly after sunset. After that, it should remain dry this weekend through early next week as high pressure shifts from our south into Arizona. Seasonal temperatures are expected this weekend into early next week. Starting Tuesday, a warm up is expected as heights centered over Arizona build. Temperatures will warm to above normal levels, though there remains a large spread in Max Temperatures on ensembles as there is also hints of increasing moisture the second half of next week. Currently, HeatRisk in southern Mohave County increases to Major starting Wednesday, and then shows Major to Extreme HeatRisk Thursday and Friday. Also seeing Major Heat Risk now in the Morongo Basin and a few spots of Clark County Thursday and Friday. Will continue to assess the magnitude of the moisture resurgence midweek and temperature/HeatRisk trends through this weekend which will drive the need for heat-related headlines late-week. && .AVIATION...For Harry Reid...For the 06Z Forecast Package...Typical overnight southwest winds at 8KT or less expected for the remainder of the overnight period. After a period of light winds Saturday morning, breezy south winds return Saturday afternoon. Winds on Saturday will be similar or slightly lighter than today. Temperatures will exceed 100F between 19z and 03z, with a high around 106F under clear skies. For the rest of southern Nevada, northwestern Arizona and southeastern California...For the 06Z Forecast Package...Winds will generally remain 10 kts or less over most areas overnight with a few gusts between 15-20 kts still possible near KDAG. Breezy south to southwesterly winds will return late Saturday morning or afternoon with speeds/gusts similar to or slightly lower than today. VFR conditions and mostly clear skies will persist through the TAF period. && .SPOTTER INFORMATION STATEMENT...Spotters are encouraged to report any significant weather or impacts according to standard operating procedures. && DISCUSSION...Nickerson AVIATION...Gorelow For more forecast information...see us on our webpage: https://weather.gov/lasvegas or follow us on Facebook and Twitter
