624 FXUS65 KREV 070837 AFDREV Area Forecast Discussion National Weather Service Reno NV 137 AM PDT Sat Jun 7 2025 .KEY MESSAGES... * Afternoon showers and thunderstorms continue into the weekend and peak Sunday and Monday. * Hot temperatures persist into early next week with moderate HeatRisk in northeast California and western Nevada. * Increased winds likely return next week, resulting in impacts to fire, travel, and recreation interests from midweek onward. && .DISCUSSION... Summer-like heat with daytime showers and thunderstorms will continue to be the main weather highlights into early next week amid a somewhat stagnant weather pattern. Nearly identical thunderstorm chances as yesterday exist this afternoon as the greatest likelihood (30-50%) favors the Sierra in Alpine and Mono County. Elsewhere, lesser chances of 10-30% reside around the Tahoe Basin towards I-80 and the Sierra Front. Northward/eastward propagating outflows will continue to serve as the mechanism for thunderstorm formation in the Greater Reno-Carson-Minden area, particularly in the 4-8 PM PDT timeframe when convection to the south and west is well underway. By Sunday and Monday, greater thunderstorm chances expand farther north and east towards Lassen County and the US-95 corridor, respectively. Temperatures slowly warm over the weekend in response to approaching high pressure with daytime highs plateauing in the mid-80s to mid- 90s from Sunday to Tuesday. These July-like highs will yield moderate HeatRisk in the lower valleys of northeast California and western Nevada this weekend through midweek. Stay hydrated and limit time in the heat if planning any weekend outdoor activities! High pressure weakens by midweek, reducing afternoon thunderstorm chances and providing steady cooling after Monday. Weak trough passages appear likely under a low-amplitude pattern, resulting in periods of increased winds from mid to late week. As such, elevated to critical fire weather conditions may return next week, along with travel and recreation impacts. -Salas .AVIATION... Periods of fog and IFR/LIFR conditions will persist at KTRK through 15Z before mixing out. Otherwise, VFR conditions and light breezes prevail through the morning. Thunderstorms continue to be the main weather concern today with KMMH and KTVL having the best odds (20-30%) of thunderstorms during the 20-03Z timeframe. A 10-30% chance of storms will exist for all other terminals this afternoon. Expect gusty outflows and sudden wind shifts, small hail, and lightning with any thunderstorms. -Salas && .REV Watches/Warnings/Advisories... NV...None. CA...None. && $$
