323 FXUS65 KVEF 160906 AFDVEF Area Forecast Discussion National Weather Service Las Vegas NV 106 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 06Z Forecast Package...Ceilings will improve overnight as showers clear out of the area. Light and variable winds will settle in from a more southerly direction, which they will continue to favor through the TAF period. Breezy southerly- to-southwesterly winds will pick up tomorrow morning with 15 to 20 knot gusts expected through the afternoon. Another round of showers will move through southern Nevada tomorrow, bringing lower CIGS to the Las Vegas Valley. Currently confidence as to whether or not these showers will directly impact the terminal area. Wind gusts will drop off and showers will clear out in the evening hours. For the rest of southern Nevada, northwest Arizona and southeast California...For the 06Z Forecast Package...Low ceilings and reduced visibilities due to moderate rainfall will continue to be a concern in the Owens Valley and the Colorado River Valley for the next few hours. Winds will generally remain light and somewhat variable into into the overnight hours before south to southwest winds develop as the rain diminishes from southwest to northeast during beginning in the early morning hours. Additional showers are expected Sunday, although coverage should be less than what was seen today. && .SPOTTER INFORMATION STATEMENT...Spotters are encouraged to report any significant weather or impacts according to standard operating procedures. && $$ DISCUSSION...Soulat AVIATION...Stessman For more forecast information...see us on our webpage: https://weather.gov/lasvegas or follow us on Facebook and Twitter
