786 FXUS65 KREV 041947 AFDREV Area Forecast Discussion National Weather Service Reno NV 1247 PM PDT Fri Jul 4 2025 .KEY MESSAGES... * Temperatures will cool to below seasonal averages this afternoon, with precipitation chances confined closest to the Oregon border in northern Washoe County and northeast California. * Breezy westerly winds and dry conditions will allow for elevated to critical fire weather as well as recreational maritime concerns this afternoon. * A gradual warming trend begins Saturday through next week where lower valleys approach the upper 90`s. && .DISCUSSION... Happy Fourth of July to everyone and especially those reading this today! I`ll start off by reminding everyone to please remain fire aware today and tonight! We`ll have a slightly enhanced zephyr breeze today causing elevated to marginally critical fire weather conditions this afternoon and evening. For additional fire weather details, please see the Fire Weather section of the AFD. The rest of today will be 5-10 degrees cooler than normal for this time of year. In western NV and northeastern CA it`ll still feel really nice out with highs in the 80`s, just may be a bit chilly in the Sierra with highs in the 60`s. Area lakes, particularly Pyramid Lake, Donner Lake, Washoe Lake, Frenchman Lake, and the Lahontan Reservoir could see gusts of 20-25 mph (just below advisory criteria) between 1 PM and 9 PM causing wave heights of 1-2 feet, so please use caution if you`re on the lakes to celebrate the holiday. We also have a couple storms already firing off in far northern Washoe County, Surprise Valley, and into northern Lassen County at the time of this AFD. We`ll maintain a 10-25% chance of showers and thunderstorms in those areas this afternoon. As for tonight, winds will still be breezy around sunset time and will become light after 10-11 PM. Looking ahead to Saturday and next week we dry out for the most part and continue to warm back up into the upper 90`s in lower valleys by Monday and could potentially hit 100 in Reno by Friday! A cut-off low off the coast of CA could bring some low chances for showers Sunday - Tuesday. Some ensembles and CAMs are showing signs of very low PoPs along the Sierra those days, so we`ll monitor that as we get closer. -Justin && .AVIATION... VFR conditions are expected across the region today and tomorrow. Breezy westerly winds this afternoon may cause some LLWS and turbulence this afternoon and evening across the Sierra Front (KRNO/KCXP/KMEV). Dry conditions are expected this weekend along with temperatures starting another warming trend. -Justin && .FIRE WEATHER... For Independence Day, elevated to locally critical fire weather conditions are expected again due to breezy westerly winds (gusts up to 25-30 mph) and low minimum relative humidity values (~7-15%) during the afternoon hours. However, the duration of elevated to critical conditions appears to be brief, and only over isolated portions of northern Washoe, the higher elevations of the NV Basin and Range, and the eastern Sierra Front. The area surrounding the Barber Fire appears to have multiple hours of critical conditions with the latest forecast update. Interests in the vicinity of the fire should take the proper precautions. Critical fire weather conditions are not anticipated over the weekend at this time as lighter winds are forecast (afternoon gusts up to around 20 mph possible) throughout the area. -078/Justin && .REV Watches/Warnings/Advisories...
