NWS Las Vegas, NV wrote its last area forecast discussion before the first event at Jul 14, 9:40 AM PST, 20 minutes earlier. Its key messages:
Area Forecast Discussion National Weather Service Las Vegas NV 1040 AM PDT Mon Jul 14 2025 .KEY MESSAGES... * Above normal temperatures will continue through the first part of the week, with the warmest readings expected today. * Gusty southwest winds will lead to areas of critical fire weather concerns Tuesday afternoon across central Nevada. * Monsoonal moisture will return to the region during the second half of the week, bringing increased chances for afternoon showers and thunderstorms. && .DISCUSSION...through Sunday. Temperatures will peak across the region today with afternoon highs averaging 5 to 8 degrees above normal. Widespread Moderate (Level 2 of 4) to Major (Level 3 of 4) HeatRisk will be seen across the southern Great Basin and Mojave Desert this afternoon. The Extreme Heat Warning remains in effect for Death Valley National Park, Clark County, and the Lake Mead National Recreation Area through this evening, along with the Heat Advisory for the southern Great Basin. Temperatures will be a few degrees cooler on Tuesday, with HeatRisk values falling into the Minor to Moderate levels in most areas. In addition to above normal temperatures early in the week, much of the region will continue to experience hazy skies as smoke from area wildfires remains trapped under the ridge of high pressure responsible for the heat. By mid-week, the ridge of high pressure will weaken as a shortwave trough moves into the Pacific Northwest. At the same time, a weak cut-off area of low pressure will develop off Baja California, which will help to transport increased moisture into the region by the second half of the week. There is still quite a bit of uncertainty about how much moisture will make it into the area. Still isolated thunderstorms will be possible starting on Wednesday across Mohave County, and then possibly moving into the Las Vegas area Thursday and Friday. This increased moisture, along with lower 500mb heights, will also allow temperatures to fall to near or even slightly below normal levels by the weekend. && .AVIATION...For Harry Reid...For the 18Z Forecast Package...Light winds favoring a southeast direction can be expected from late morning through early evening before shifting to southwest. VFR conditions expected at the terminal, with isolated afternoon showers and thunderstorms in the Peach Springs corridor. Wildfire smoke aloft will remain in the skies. Temperature will exceed 100 degrees through 06Z, peaking around 112 degrees. For the rest of southern Nevada, northwest Arizona and southeast California...For the 18Z Forecast Package...Winds will be mainly from the south to southwest today, except where terrain dictates otherwise, with gusts of 15 to 25 knots common around the region. Wildfire smoke aloft will remain in the skies, with VFR conditions expected at the surface. Isolated thunderstorms are possible this afternoon over portions of northwest Arizona. && .FIRE WEATHER...A short wave moving through the Great Basin will bring elevated winds to the southern Great Basin on Tuesday. This, along with afternoon relative humidity values of 7 to 14 percent, will potentially result in critical fire weather conditions across Nevada Fire Weather Zone 461, and a Fire Weather Watch has been issued for Tuesday in that area. While winds will still be breezy on Wednesday, increasing moisture levels will result in RH values of 10 to 20 percent, which will help to mitigate fire risk. && .SPOTTER INFORMATION STATEMENT...Spotters are encouraged to report any significant weather or impacts according to standard operating procedures. && DISCUSSION...Planz AVIATION...Gorelow FIRE WEATHER...Planz For more forecast information...see us on our webpage: https://weather.gov/lasvegas or follow us on Facebook and Twitter
