568 FXUS65 KREV 132117 AFDREV Area Forecast Discussion National Weather Service Reno NV 217 PM PDT Wed Aug 13 2025 .KEY MESSAGES... * Showers and thunderstorms probable this afternoon south of Highway 50, becoming confined to Mono and Mineral County Thursday. * Hot today with a cooling trend through the weekend. Breezy winds each afternoon should produce minor impacts to fire, aviation, and recreation. * Increasing chances of showers and thunderstorms this weekend near the Oregon border with a warming trend next week. && .DISCUSSION... Showers and isolated thunderstorms will continue to develop through the afternoon in Mono, S. Lyon, Mineral, and E. Churchill counties. Strong outflow winds up to 60 mph will serve as the primary impact today, but t-storms will also be capable of 0.25-0.50" hail, brief heavy downpours, blowing dust near desert sinks and playas, and occasional lightning. Shower and storm activity should linger into the early evening before tapering off by 8 PM PDT. Farther north away from storms, breezy west winds with gusts of 20-30 mph will yield areas of elevated fire weather conditions and minor impacts to travel and recreation through sunset. A drying trend will limit thunderstorm coverage on Thursday, confining best odds of 10-20% to Mono and Mineral counties. Hot weather sticks around for the rest of the week, but weakening high pressure will provide several days of cooling. As a result, temperatures return to seasonal averages Thursday and even dip below average over the weekend. Winds will remain breezy each afternoon heading into the weekend, but are not expected to stronger than our typical zephyr. Low pressure will anchor in the eastern tier of the Gulf of Alaska this weekend, directing abnormally rich moisture into the Pacific Northwest. As a result, shower and thunderstorm chances increase across Lassen County and N Washoe County Saturday and Sunday afternoons. Winds may also trend slightly stronger on Saturday, but should still be on par with typical zephyr breezes. Slow warming will accompany building high pressure next week with shower/storm chances possibly shifting to areas south of Tahoe/Reno around midweek. -Salas && .AVIATION... Isolated thunderstorm development south of US-50 will persist through the afternoon with KMMH having the greatest likelihood (30- 40% chance) of storm impacts until 02Z. Elsewhere, SW/W surface gusts of 20-30 kts may present minor LLWS impacts into the early evening -- especially at KRNO-KCXP-KMEV where gusts are strongest. Isolated showers and storms will be possible at KMMH Thursday afternoon (10-20% odds) while VFR conditions and typical afternoon breezes prevail elsewhere. -Salas && .REV Watches/Warnings/Advisories...
