543 FXUS65 KREV 061920 AFDREV Area Forecast Discussion National Weather Service Reno NV 1220 PM PDT Mon Oct 6 2025 .KEY MESSAGES... * Below average temperatures today, then a warming trend arrives Tuesday into at least Thursday, with dry weather. * Another system by the end of the week, but confidence in the specifics remains low. && .DISCUSSION... Below average high temperatures today will increase to above normal by Wednesday, bringing overnight lows up as well. Wednesday looks to be the warmest day of the week with valley highs in the upper 70s and Sierra highs in the upper 60s to low 70s. Overnight lows will flirt with subfreezing temperatures along the Sierra again tonight before increasing into the mid 30s by midweek. Dry conditions will accompany these warming temperatures through at least Thursday. A trough is expected to drop down midweek, bringing impacts to the area by Friday. Impacts include widespread shower chances, gusty afternoon winds, and much cooler temperatures. However, while models are starting to resolve the uncertainty a bit with the latest run, there`s still ambiguity on the timing of this system. Regardless, though, showers can be expected to start in NE CA before pushing into the Sierra south of the Tahoe Basin and into W NV. Friday looks to be the windiest day of the week with gusts upwards of 60 mph along the ridges. There`s even some potential for some snow flurries along the Tahoe Basin on Friday! Snow levels drop to 7-8 kft Friday afternoon and into the evening hours. Temperatures will drop, as well, with "chilly" afternoons settling back in (highs in the low 60s and low 50s for valleys and mountains, respectively). This system might just be the thing that firmly solidifies "fall" across much of the area. -Giralte && .AVIATION... VFR conditions through much of this week for all terminals with light winds. The only exception will be KTRK where FZFG is expected to develop between 07/11Z-07/16Z. -Giralte && .REV Watches/Warnings/Advisories... NV...None. CA...None. && $$
