091 FXUS65 KVEF 110843 AFDVEF Area Forecast Discussion National Weather Service Las Vegas NV 143 AM PDT Fri Jul 11 2025 .KEY MESSAGES... * Smoke from nearby fires will result in hazy skies at times today and Saturday, but significant or widespread smoke impacts near the surface are not expected. * Hot and dry conditions will continue through the weekend and into early next week as ridging persists across the region. && .DISCUSSION...Today through the Middle of Next Week. Winds will remain light from the south to southwest today with high pressure sitting over the area. This will reduce significant advection of smoke from fires in Nye and Lincoln counties. The HRRR shows high concentrations of smoke through southern Nevada into southwest Utah, but no visibility reductions of significant near-surface smoke far from the actual fires. Expect hazy skies at times today and Saturday through southern Nevada into northern Mohave County A ridge of high pressure centered over southern California will build over the region through the weekend. This will result in gradually increasing temperatures. The hottest days should be Sunday and Monday when heights reach +1.0 to +1.5 sigmas. Above normal temperatures are likely through the period, with high temperatures climbing 6-8 degrees above normal Sunday and Monday. Widespread Moderate (Level 2 or 4) HeatRisk is forecasted this weekend and Monday with isolated areas of Major (Level 3 of 4) HeatRisk in the desert valleys of Inyo County into southern Nevada on Sunday. Anyone with outdoor plans should be prepared for hot temperatures, especially if they are sensitive to heat. 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 06Z Forecast Package...Expect breezy winds around 8 kts with wind directions following typical diurnal patterns... east-northeasterly picking up late-morning, southeasterly through the afternoon, and southwesterly around sunset, with a brief period of light and variable winds in the early morning.
