015 FXUS65 KVEF 020356 AFDVEF Area Forecast Discussion National Weather Service Las Vegas NV 856 PM PDT Fri May 1 2026 .KEY MESSAGES... * The warming trend and periods of breezy winds will continue through the weekend. * Cooler conditions and gusty winds will return next week with increased chances for shower activity across the Sierra and Great Basin. && .DISCUSSION...through next week. Breezy northerly winds continue today as a shortwave swings through Utah and Arizona. The highest gusts so far today have been down the Colorado River Valley between 30 and 40 mph. Elevated winds should last through sunset and weaken overnight. Temperatures increase today and tomorrow as a shortwave ridge passes through and heights aloft rise. The ridge starts to drift east and heights aloft decrease on Sunday as low pressure moves into the west coast, but sufficient mixing should allow for more warming for the eastern half of the forecast area. In Las Vegas, there is a 75 percent probability of reaching a high of 90 degrees on Sunday at KLAS. The previously mentioned low pressure system will lead to increased winds, precipitation chances, and cooler temperatures next week. Strong 850 mb winds support gusty southerly to southwesterly winds starting on Saturday afternoon in southeastern California, ramping up and spreading east on Sunday. The strongest winds should occur over high terrain. However, there are greater than 70 percent probabilities for gusts over 40 mph in certain valleys in Inyo and San Bernardino counties, as well as the Colorado River Valley. Elevated winds may also continue into Monday in the western Mojave Desert as the low slowly exits to the east. Will continue to monitor to determine if wind headlines become necessary. Precipitation chances favor the eastern Sierra and southern Great Basin on Monday and Tuesday. A few instability driven showers and thunderstorms are possible areawide later on Tuesday and Wednesday as the center of the low passes overhead. Temperatures drop 10 to 15 degrees between Sunday and Tuesday before rebounding the rest of the week as ridging returns. && .AVIATION...For Harry Reid...For the 06Z Forecast Package...
