390 FXUS65 KREV 041943 AFDREV Area Forecast Discussion National Weather Service Reno NV 1243 PM PDT Sat Oct 4 2025 .KEY MESSAGES... * Below average temperatures through the start of next week, with dry conditions. * A warming trend arrives Tuesday into at least Thursday, with dry weather. && .DISCUSSION... Cool, northerly breezes will work to keep us on the chilly side through early next week. The trough draped across the western U.S. will allow for this to remain the case, as another shortwave will glide along the Pacific periphery of the trough by Sunday to reinforce our cool air. We don`t anticipate much in the way of precipitation, and only a modest increase in breezy ridge winds to accompany the shortwave. Keep the sweaters and quilts handy at night, especially in the Sierra. Overnight temperatures will tumble toward at or below freezing for Sierra valleys. Sierra front locations will have to wait a bit longer for freezing overnight lows. Things get interesting for midweek as solutions start to meander around the presence of either a deep impactful trough with plentiful moisture, or a ridging pattern that warms and dries us out. As we get closer in time the details will iron out, but for now, it could be 80 and sunny or 60 and showery. This much variability is a marker of fall seasons, when the solution patterns become wildly varied as the season changes. HRICH && .AVIATION... * VFR conditions for most terminals, while some Sierra terminals may see clouds early that could contribute to mountain obscurations. This will clear up as the afternoon arrives and the low pressure system moves eastward. * Winds are light today, with afternoon gusts to 15 kts. HRICH && .REV Watches/Warnings/Advisories... NV...None. CA...None. && $$
