470 FXUS65 KVEF 112012 AFDVEF Area Forecast Discussion National Weather Service Las Vegas NV 110 PM PDT Fri Jul 11 2025 .KEY MESSAGES... * Smoke from nearby fires will result in hazy skies at times through Saturday, but significant or widespread smoke impacts near the surface are not expected. * Hot and dry conditions will continue through the weekend with temperatures peaking Monday as ridging persists across the region. * Monsoon moisture makes a possible return mid to late next week along with a drop in temperatures. && .DISCUSSION...Today through the Middle of Next Week... High pressure over the region will allow temperatures to climb through the weekend and into early next week with temperatures peaking Monday. HeatRisk is mostly in the Moderate (Level 2) Saturday, but we are starting to see more isolated pockets of Major (Level 3) on Sunday. HeatRisk on Monday shows the greatest coverage of Major (Level 4) with temperatures running about 5-8 degrees above normal; however, these temperatures will still fall a few degrees shy of record values. At this point, decided to hold off on any Heat Warnings, but will continue to monitor. Hazy skies are expected over the next couple of days as various fires burn across the region combined with generally light winds aloft. The Gothic Fire located in central Nye county is the largest fire and has been responsible for most of our hazy conditions. So far today, smoke production has been much less than previous days but that will need to be watched this afternoon if another significant plume gets generated. The ridge will slowly retreat and weaken next week after Monday. Temperatures will cool off a bit each day in response. In addition, on Tuesday a slight increase in moisture is expected. This moisture will not result in any precipitation but will help cool temperatures and also reduce any fire danger due to extremely dry conditions. On Wednesday, high temperatures will have fallen back closer to normal for this time of the year. Any precipitation chance is now not expected until Thursday or later when better moisture and an easterly shortwave could bring low chances for precipitation. && .AVIATION...For Harry Reid...For the 18Z Forecast Package...Light light to occasional east to southeast winds will prevail through much of the afternoon. Wind speeds overall are expected to remain under 7kts. We are expected to see winds increase slightly out of the southeast after 23Z 8-10kts with occasional gusts to around 15kts. This should continue through 03Z before winds settle to the southwest overnight around 10kts. The primary concern aside from winds will be potential visual obscurations early evening into tonight due to smoke/haze from a wildfire in Nye County. Most smoke is expected to remain lofted. Temperatures will exceed 100F through 05Z, peaking at 108F around 00Z. For the rest of southern Nevada, northwest Arizona and southeast California...For the 18Z Forecast Package...The main aviation concern will be focused across Las Vegas Valley terminals this evening into tonight, as wildfire smoke from Nye County is expected to advect southeastward. Most smoke will remain lofted, with a slight potential of some visual obscurations; however, at this time confidence is too low to include cloud groups in the TAF. Across the Western Mojave, elevated and gusty westerly winds persist, and elsewhere across the Owens Valley and Lower Colorado River Valley, typical diurnal wind patterns are expected with upvalley winds developing late morning into early afternoon. && .SPOTTER INFORMATION STATEMENT...Spotters are encouraged to report any significant weather or impacts according to standard operating procedures. && DISCUSSION...Gorelow AVIATION...Gorelow For more forecast information...see us on our webpage: https://weather.gov/lasvegas or follow us on Facebook and Twitter
