358 FXUS65 KREV 261921 AFDREV Area Forecast Discussion National Weather Service Reno NV 1221 PM PDT Sat Sep 26 2026 .KEY MESSAGES... * Cooler temperatures this weekend with afternoon breezes gusting up to 25-30 mph. * 20-50% chance for light rain and high elevation snow showers (>9,000`) across the eastern Sierra and western Nevada Sunday night into Monday afternoon. * Ridging returns Tuesday, leading to a warming and drying trend through next weekend. && .DISCUSSION... High temperatures today will be near normal, which equates to low 80s for valleys and low 70s for Sierra communities. Those temps drop 5-10 degrees for Sunday and Monday, with highs in the mid to low 70s for valleys and mid 60s for Sierra communities. Overnight lows Monday and Tuesday mornings will flirt with near freezing for colder Sierra valleys (Truckee, Martis Valley, Bridgeport, etc.). Afternoon breezes will gust up to 25-30 mph both today and tomorrow, with locally higher (40+ mph) along ridgetops. These southwesterly breezes will help transport smoke and haze from the Dome fire in Yosemite. Expect reductions in air quality primarily down the US-395 corridor from Walker to Bridgeport. However, said air quality reductions are dependent on smoke production. For details on air quality, please visit www.fire.airnow.gov. A trough off the PacNW coast will sag southward as we get into Sunday, which introduces precipitation chances across much of W NV and the Sierra late Sunday night into Monday afternoon. The primary precip type will be light rain (20-50% chance), with up to half an inch of snow possible (40-60% chance) above 9000` for the Eastern Sierra of Mono county and the White Mountains. Rain totals will amount to 0.1" or less, primarily south of I-80, with the most likely time frame for showers during the Monday AM commute. There`s a 20-40% chance for patchy fog for Truckee and adjacent areas Monday morning, though this is dependent on if there will be showers over the area or not. Ridging returns by Tuesday, helping warm temperatures to above normal values as we close out September. Dry conditions with light winds are expected to prevail through at least next weekend. -Giralte && .AVIATION... VFR conditions today with SW wind gusts of 20-25 kts.
