409 FXUS65 KVEF 161733 AFDVEF Area Forecast Discussion National Weather Service Las Vegas NV 0930 AM PST Sun Nov 16 2025 .KEY MESSAGES... * Another weather system will impact the Desert Southwest on Monday and Tuesday, returning widespread rain and mountain snow to the region. * Active weather continues through the forecast period, with the following system expected late-week. && .DISCUSSION...Today through Saturday. On Monday, the next weather system will approach the region. The trajectory of the moisture plume with this system will be more typical - allowing the Sierra Nevada Mountain Range to rain-shadow much of the Mojave Desert. That said, we`re still assessing the potential for spillover precipitation to return widespread rainfall chances to southeastern California, southern Nevada, and northwestern Arizona. Pre-frontal snow levels will be slightly lower than we experienced with our last system, ranging from 6500 to 7500 feet. Post-frontal snow levels will drop to around 5500 feet, allowing for snowfall accumulations in more sensitive locations. While the majority of snowfall will occur above 9500 feet, between 2 and 6 inches can be expected above 6000 feet. As such, issued a Winter Weather Advisory for the eastern Sierra slopes, Inyo Mountains, White Mountains, Spring Mountains, and Sheep Range. Due to the potential for travel-impacting snow accumulations along State Route 266 through Lida Summit, issued a Winter Weather Advisory for Esmeralda / central Nye above 6000 feet as well. Elsewhere, expect light-to-moderate rainfall with an isolated lightning strike possible Monday and Tuesday. Afternoon high temperatures will drop to between 8 and 10 degrees below-normal. The region will experience a break from precipitation on Wednesday before our attention turns to another weather system approaching the region late-week. As mentioned in the previous discussion, changes to the forecast track can have substantial impacts to the forecast, resulting in low confidence at this time. && .AVIATION...For Harry Reid...For the 18Z Forecast Package...Breezy south-southwest winds are expected today with gusts in the 15-20 knot range. SCT-BKN clouds are expected through the day with CIGS between 6-8kft. Showers may occur in the vicinity of the terminal through the afternoon but are more favored east of the city. Winds should settle down after sunset, and VFR conditions are expected tonight. Clouds are expected to increase again Monday, with CIGS again between 6-8kft AGL. For the rest of southern Nevada, northwest Arizona and southeast California...For the 18Z Forecast Package...The worst weather today is expected in an arc from the Owens Valley across the southern Great Basin and southward through Mohave County, where low ceilings and reduced visibilities in rain and high mountain snow will continue to be a concern. Elsewhere, expect prevailing VFR conditions with areas of MVFR/IFR in scattered showers. South to southwest winds gusting 15 to 30 knots can be expected over much of the region today, settling down after sunset. VFR conditions are likely areawide overnight before the next round clouds moves in Monday, with shower chanced mainly across the Sierra and far western Mojave Desert region. && .SPOTTER INFORMATION STATEMENT...Spotters are encouraged to report any significant weather or impacts according to standard operating procedures. && $$ DISCUSSION...Soulat AVIATION...Outler/Morgan For more forecast information...see us on our webpage: https://weather.gov/lasvegas or follow us on Facebook and Twitter
