FXUS65 KREV 251015 AFDREV Area Forecast Discussion National Weather Service Reno NV 315 AM PDT Sat Oct 25 2025 .KEY MESSAGES... * Gusty winds, rain and high elevation snow showers are expected this weekend mainly from Highway 50 northward. Strongest wind gusts expected today. * Below average temperatures are expected this weekend, especially Sunday when highs will be 15-20 degrees cooler than today. * Warmer and drier conditions with mainly light winds return next week.&& .DISCUSSION... Early morning radar depicts a swath of light rain draped across Lassen County, moving eastward toward northwestern Nevada. This development will continue as a trough sweeps across the Pacific Northwest. Gusty winds, valley rains and high elevation snow are all possible today, mostly north of US-50. This frontal passage will bring cooler temperatures for the weekend, while next week a warmup is shaping up. Our first few drops have already fallen across northeastern California, and by Sunday night we could see up to 0.75-1.00" of liquid along the Donner Pass, which could mix in with some snow for late Saturday into Sunday. Snow totals will be rather limited given snow levels will rise later today to near 8500-9000 feet, before falling to 7000-7500 feet by Sunday evening. The snow levels will fluctuate between now and Sunday night, suggesting the precipitation type will oscillate near those snow levels from rain to rain/snow mix. The only locations that will see all snow for this event will be above the 8500-9000 feet mark. Overall, snow amounts will be light and generally less than an inch with the highest peaks receiving up to 4 inches by Sunday night. As for showers across western Nevada valleys, the spillover will be limited to the near leeside foothills. There, liquid amounts will be 0.25-0.5", with less than 0.1" spilling over into the Greater Reno-Carson City- Minden region. Gusty winds will be the more prominent feature of this system, with ridge gusts today approaching 100 mph along the ridges. Gusts in the valleys could reach 45 mph early this afternoon. Make certain to secure outdoor holiday decorations today. Gusts will continue Sunday, as the remnants of the current system work across the area. Gusts will reach near 100 mph on the ridges, while valleys could see gusts 50-55 mph. The Tahoe Basin will also see increased winds over the open waters, which will introduce some choppy conditions. Elsewhere, the risk for blowing dust will be present today into Sunday for Basin and Range locations that lie downwind of desert sinks and dry lake beds. Thus, we have issued a Wind Advisory for Sunday in response to the increased strong wind threat south of I-80 within the Sierra and along the Sierra Front in western Nevada. The trough will also drag down some cooler temperatures for the weekend along with all the items detailed above. Today we will see highs near seasonal averages, Sunday we will take around 5 degrees off of today's high temperatures. Once we say hello to the new week, we will say goodbye to the trough and it's cooler temperatures. next week we will see temperatures rebounding to above average, with a ridge allowing a drier air mass. HRICH && .AVIATION... * Gusty southwest winds today will bring gusts of nearly 40 kt to leeside terminals such as KRNO/KCXP/KMEV. Sierra ridges will see gusts 80+ kts, which will introduce LLWS through the day. Sierra terminals such as KTRK and KTVL may see intermittent periods of terrain obscuration as bands of precipitation rotate through the region. * Sunday will bring similar results to area terminals, with gusty winds, rain/snow showers and LLWS remaining.
