112 FXUS65 KVEF 120821 AFDVEF Area Forecast Discussion National Weather Service Las Vegas NV 121 AM PDT Sat Jul 12 2025 .KEY MESSAGES... * Smoke from nearby fires will result in hazy skies at times through at least 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 Friday. Hazy skies are expected at times 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 the hazy conditions through much of Southern Nevada the past few days. This should continue today though the smoke plume is less robust on HRRR smoke compared to previous days. In addition, new fires in north-central Arizona may also produce smoke aloft with the HRRR showing smoke advecting through Mohave County at times tonight and Saturday. Smoke continues to be aloft with minimal near surface or visibility reductions noted on the HRRR and probabilistic models. Above normal temperatures will continue as high pressure will continue to build over the region through Monday. The hottest days will be Sunday and Monday when heights reach +1.0 to +1.5 sigmas. High temperatures will climb 6-8 degrees above normal Sunday and Monday. Widespread Moderate (Level 2 or 4) HeatRisk is forecasted this weekend. On Monday, the HeatRisk forecast continues to fluctuate and now the area of Major (Level 3 of 4) HeatRisk is more widespread from previous forecasts in the mid to low elevations. Will continue to monitor temperatures and trends as a heat product may be needed for Monday. The ridge will slowly retreat and weaken after Monday. Temperatures will cool off each day in response starting Tuesday. 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 closer to normal and expected to remain near normal through the rest of the week. Any precipitation chance is now not expected until Thursday or later when better moisture and an weak shortwave could bring low chances for precipitation. From the previous forecast, late week moisture increases and precipitation chances have not changed significantly. && .AVIATION...For Harry Reid...For the 06Z Forecast Package...Expect light winds at or below 8 kts with wind directions following typical diurnal patterns... light and variable through the morning, southeasterly through the afternoon, and southwesterly after sunset. Cannot rule out an occasional gust between 15 and 20 kts from the southeast between 00 and 03Z with peak heating as winds veer to the southwest through sunset. Slantwise visibility reductions expected from all directions through the TAF period, due to wildfires in south-central Nevada and northern Arizona. Included a FEW120 through the overnight period at Las Vegas Valley terminals as a result. Otherwise, no operationally significant cloud cover. Temperatures will exceed 100 degrees on Friday between 18 and 05Z. For the rest of southern Nevada, northwestern Arizona and southeastern California...For the 06Z Forecast Package...Expect breezy winds in the Las Vegas Valley at or below 8 kts with generally a diurnal direction trend. Cannot rule out isolated gusts between 15 and 20 kts from the southeast in the late-afternoon before winds shift southwest. Breezy south-southeast winds at KBIH in the afternoon.. Gusty west winds persist at KDAG, with a typical decrease expected during the late-morning and afternoon.
