555 FXUS65 KREV 010725 AFDREV Area Forecast Discussion National Weather Service Reno NV 1225 AM PDT Thu Oct 1 2026 .KEY MESSAGES... * Dry weather prevails through Saturday with above normal temperatures lasting through next week. * Weak low pressure brings a low chance of showers and thunderstorms in the eastern Sierra and northeast CA on Sunday into Monday. * Warmer and drier than normal weather is favored through at least mid-October. && .DISCUSSION... Large scale ridge over the western U.S. will be the dominant feature through next week. The only exception to this is a weak low pressure moving through the region on Sunday into Monday. After this low pressure moves out, models and ensembles have good agreement that high pressure will once again re-strengthen across the western U.S. Weather-wise, with this ridge overhead temperatures will trend upward today through Saturday. During this time, mid 80s to low 90s will be common for western NV valleys, eastern Lassen, and the lower elevations of Mono County. Temperatures for the eastern Sierra valleys will range from the mid 70s to mid 80s, with even upper 50s to mid 60s for the higher elevations. These temperatures are upwards of 10-15 degrees above average, and more analogous to readings we see in late August. Speaking of the aforementioned weak low pressure, the most this feature will do is decrease temperatures on Sunday and Monday by around 1-3 degrees. Also, models and blended guidance have trended lower with precipitation chances for the eastern Sierra and northeast CA on Sunday and Monday, now at only 5-10%. After this weak low moves out, we remain dry with well above average temperatures all the way into next week. That`s all I have folks. Enjoy the warm weather while you can. -McKellar && .AVIATION... High pressure maintains widespread VFR conditions and light breezes into the weekend. A weak low pressure passage will deliver a low chance (5-10%) of showers and thunderstorms to KTRK-KTVL-KMMH Sunday into Monday. -McKellar && .REV Watches/Warnings/Advisories... NV...None. CA...None. && $$
