521 FXUS65 KREV 191037 AFDREV Area Forecast Discussion National Weather Service Reno NV 337 AM PDT Sat Sep 19 2026 .KEY MESSAGES... * Dry and mild weather for the weekend with periods of breezy east to northeast winds along the Sierra crest. * Low chances of rain and thunderstorms return to the eastern Sierra early next week. Warm and dry elsewhere. * Increased winds with low chances of rain and thunderstorms are favored late next week into next weekend. && .DISCUSSION... Plan on a mild and dry weekend as transient high pressure takes residence across the Sierra and western Nevada. High temperatures will be around seasonal averages along with relatively light winds areawide. East to northeast ridge winds may be more breezy through the weekend with gusts up to 30 mph possible. Temperatures will be seasonally cool each night with most of the smoke/haze dispersed from the area as well. The east to northeast flow should limit wildfire smoke infiltrating into the eastern Sierra through the weekend. High pressure doesn`t stick around very long as a weak, cutoff low sweeps across central CA into NV from late Sunday into Monday. Blended guidance shows low chances for precipitation (10-20%) associated with the low passing through, but primarily for areas south of Lake Tahoe in Mono and Mineral counties. Thunder probabilities are fairly scant (8-10%), but can`t rule it out completely. Otherwise, it will be pretty dry and warm for the rest of the region. Ensemble clusters hold steady with the trend of a large trough off the West Coast for late next week into next weekend. Blended guidance also maintains the potential for slightly wetter and more windy conditions from Friday onward with the large trough in the vicinity. -Edan && .AVIATION... Plan on VFR conditions today with light north to northeast breezes in the afternoon. The E-NE winds along and west of the Sierra crest will be breezy through the weekend, which may result in minor mountain wave turbulence concerns along and west of the Sierra. -Edan && .REV Watches/Warnings/Advisories...
