NWS Reno, NV wrote its last area forecast discussion before the first event at Jul 28, 1:38 PM PST, 5 hours 44 minutes earlier. Its key messages:
Area Forecast Discussion National Weather Service Reno NV 238 PM PDT Mon Jul 28 2025 .KEY MESSAGES... * Areas of showers and isolated thunderstorms expected through the afternoon and ending in the evening. * Thunderstorm activity increases Tuesday and Wednesday, posing a risk of heavy rain and flooding, gusty outflow winds, small hail, and frequent lightning. * A drying trend will limit thunderstorms after Wednesday with increasing breezes possible over the weekend. && .DISCUSSION... Weak low pressure is lifting through northern California per 19Z moisture-channel imagery and will assist in shower and thunderstorm development this afternoon. Coverage will be limited today -- even more so than yesterday -- with greatest likelihood favoring Lassen County, the Surprise valley into far N Washoe County, and from the Quad Counties to the US-95 corridor. Showers and storms may develop along the Sierra north of Tahoe, but odds of this occurring are lower. Otherwise, it'll take well-placed outflows to initiate storms away from these areas. Thunderstorms will be capable brief heavy downpours, gusty outflow winds and blowing dust near desert sinks and playas, small hail, and lightning. Thunderstorm activity trends upward Tuesday and Wednesday as a better defined low pressure area pivots through the region. Greater instability coupled with rich moisture aloft will increase chances of storms to 20-40% and 30-60% Tuesday and Wednesday afternoons, respectively. NE California and NW Nevada will continue to be the most favorable areas, including Tahoe communities and the Greater Reno-Carson-Minden area. Guidance remains keen on the prospect of nocturnal showers and storms from the Tahoe Basin northward Tuesday night into Wednesday morning, which corresponds to when the low pressure moves overhead. Potential impacts are the usual suspects -- strong outflows, small hail, lightning and new fire starts, blowing dust -- but heavy rain and flash flooding is possible given abnormal moisture aloft. Needless to say, expect more stormy weather through midweek. Moisture scours out in the wake of the low passage, reducing thunderstorm chances and coverage after Wednesday. There is still the potential for increased afternoon breezes and elevated fire concerns this weekend into early next week, but confidence remains low on timing/magnitude. -Salas && .AVIATION... * VFR conditions will give way to MVFR for some terminals. Clouds will continue to develop as storms arrive once again for this afternoon. Chances are greatest for KCXP and KMEV (20-25% chance), while KTRK, KRNO and KTVL have lower chances (10-15%). KSVE may see showers initiate nearby then move northward into the afternoon and evening. Gusty outflow winds, small hail, heavy rains and frequent lightning are possible as well as terrain obscuration in the vicinity of ongoing storms. * Showers and storms return each day this week for much of the region, with the later week storms firing near the Oregon border. HRICH && .FIRE WEATHER... Thunderstorm coverage and lightning density increases Tuesday and Wednesday, elevating the potential for new ignitions regionally. However, there are competing factors that limits confidence in the overall lightning threat for midweek. Abundant lightning is becoming more probable each afternoon, particularly in northeast California and near the Oregon border where thunderstorm coverage is favored to be greatest. Storm motions will also be moderate, reducing the residence time of rain cores over any lightning start. To make matters more complicated, there is the possibility of nocturnal lightning Tuesday night into Wednesday morning from the Tahoe Basin northward as the low passes overhead. With all that being said, thunderstorms will trend on the wetter side owing to rich moisture aloft. Furthermore, the areas near the Oregon border have received considerable rainfall over the last several days, keeping fuels saturated. The main takeaway is that increasing lightning production from wetter thunderstorms is expected Tuesday and Wednesday, and may result in new ignitions away from rain cores. -Salas && .REV Watches/Warnings/Advisories...
