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 Jul 3, 11:42 PM PST, 18 minutes earlier. Its key messages:
Area Forecast Discussion National Weather Service Las Vegas NV 1242 AM PDT Fri Jul 4 2025 .KEY MESSAGES... * Breezy and dry conditions will promote high fire spread potential today and tonight. * Areas of haze and smoke from distant wildfires will spread across much of Southern Nevada and California today through the weekend. * Potential for a significant heat wave is increasing from the middle of next week into next weekend. This looks to be the hottest weather we have seen since last summer. && .DISCUSSION... Wildfire danger will be heightened today due to the combination of hot, dry and breezy weather, and July 4th activities. See the Fire Weather discussion below for more details. Ongoing wildfires across Southern California, most notably the Madre fire burning north of Santa Maria, will continue to generate smoke and haze. As southwesterly winds overpread the region today into the weekend, expect at least patchy smoke and widespread haze to affect much of adjacent Southern California and Southern Nevada. This combined with July 4th festivities may result in poor air quality today through the weekend. Follow the guidance of local air quality agencies if you have outdoor plans over the holiday weekend. As we get into next week, ensembles depict a cutoff low off of the Southern California coast will gradually retrograde, allowing a powerful upper ridge of high pressure to build in across the Four Corners region. This feature will slowly build westward, becoming positioned over Southern California, Nevada and western Arizona. Long-range ensembles are rather confident on this dominant ridge having a prolonged presence across the Desert Southwest. As such, the potential for a significant multi-day heat event are on the rise. Heat Risk will climb daily, with widespread Major to Extreme Heat Risk evident Wednesday and Thursday of next week, likely continuing through the following weekend. We will have to monitor trends closely as this feature looks to bring the hottest weather we have seen since last summer. && .AVIATION...For Harry Reid...For the 06Z Forecast Package...Much quieter weather is expected Friday. The main concerns will be southerly winds gusting around 25 knots in the afternoon and smoke from fireworks after sunset. Few or no clouds expected. For the rest of southern Nevada, northwest Arizona and southeast California...For the 06Z Forecast Package...Much quieter weather is expected Friday, with only a tiny chance for a thunderstorm in Lincoln and Mohave counties. Otherwise, the main concerns will be south to southwest winds gusting 20 to 30 knots areawide in the afternoon, with gusts as high as 40 knots in the Death Valley National Park area, before subsiding in the evening. Areas of smoke from fireworks can be expected near populated areas after sunset. && .FIRE WEATHER... The combination of hot and dry weather with increasing southwesterly breezes will lead to high fire spread potential today into early tonight. This combined with dry vegetation and July 4th activities will lead to an increased risk of wildfires. Red Flag Warnings remain in effect for much of Southern Nevada into western Arizona beginning late this morning and lasting into tonight. Hot and dry conditions will persist into the weekend and beyond, but winds will generally be on a downward trend. && .SPOTTER INFORMATION STATEMENT...Spotters are encouraged to report any significant weather or impacts according to standard operating procedures. && KEY MESSAGES/DISCUSSION/FIRE WEATHER...Austin AVIATION...Morgan For more forecast information...see us on our webpage: https://weather.gov/lasvegas or follow us on Facebook and Twitter
