207 FXUS65 KVEF 290828 AFDVEF Area Forecast Discussion National Weather Service Las Vegas NV 128 AM PDT Fri Aug 29 2025 .KEY MESSAGES... * Isolated thunderstorms remain possible, mainly across Inyo County and central Nevada today. * Dry conditions and near to above normal temperatures return this weekend through midweek next week, with a resurgence of monsoonal moisture toward the middle to end of next week. && .DISCUSSION... Remnant moisture from former TS Juliette continues to stream across the eastern CWA this morning. Rainfall amounts have generally been light with areas across the lower Colorado River Valley and Mohave County generally receiving less than a tenth of an inch. Instability has remained rather weak due to the thick cloud cover so anything more than just a few light to moderate showers is not expected through this morning. This morning will continue to stream north this morning, but most of the shower activity will end just after sunrise leaving much of the area under mostly sunny skies. PW will begin to lower across the region and most of the area will remain fairly stable through the day. The one area that has the better chance of seeing afternoon thunderstorms will be across northern Lincoln County where CAPE values of 250-500 j/kg will exist. Still, any thing that does develop will be fairly isolated and generally weak. Over the weekend, high pressure will rebuild over the region with temperatures warming to above normal readings by Sunday. Not only will temperatures warm, but much drier air will work into the region ending the threat of daily showers and thunderstorms. Drier air looks to remain in place through the early part of next week, which is a change from previous ensemble runs. The latest ensemble runs are showing that PW will rise to around 120-150 percent of normal by Wednesday. We could start to see thunderstorm chances increase Tuesday, but at this point the better opportunity for seeing scattered showers and thunderstorms will occur during the middle to later part of next week. && .AVIATION...For Harry Reid...For the 06Z Forecast Package...Winds will remain light, 10 knots or less, and will follow typical diurnal directional trends with periods of light and variable winds as they transition. Mid and high-level clouds with bases AOA 12kft AGL will continue to filter through southern Nevada as remnant moisture from Tropical Storm Juliette streams across the region. Temperatures will remain below 100F tomorrow. For the rest of southern Nevada, northwest Arizona and southeast California...For the 06Z Forecast Package...Mid and high-level clouds with bases AOA 12kft AGL will continue to filter southeastern California, southern Nevada, and northwestern Arizona as remnant moisture from Tropical Storm Juliette streams across the region. Weak, isolated showers are embedded within these clouds and may produce light rain in places. Winds will remain under 10 knots with winds tending to follow typical diurnal directional trends through Friday afternoon. Winds may become light and variable at times as they transition. Smoke from the Garnet wildfire burning on the west side of the Sierra will continue to filter into the Owens Valley and is expected to occasionally impact surface visibility over the next few hours. Guidance shows improvement early Friday morning and into the afternoon before another round of smoke pushes into the Owens Valley tomorrow night. && .SPOTTER INFORMATION STATEMENT...Spotters are encouraged to report any significant weather or impacts according to standard operating procedures. && $$ DISCUSSION...Gorelow AVIATION...Stessman For more forecast information...see us on our webpage: https://weather.gov/lasvegas or follow us on Facebook and Twitter
