Tropical moisture associated with the remnants of Hurricane Kay streamed north-northeast across the Sierra and western NV and resulted in areas of heavy raifall from showers forming across the region.

The episode as NWS REV wrote it up.
Tropical moisture associated with the remnants of Hurricane Kay streamed north-northeast across the Sierra and western NV and resulted in areas of heavy raifall from showers forming across the region.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Reno, NV wrote its last area forecast discussion before the first event at Sep 6, 12:33 PM PST, 2 hours 27 minutes earlier.
Area Forecast Discussion National Weather Service Reno NV 133 PM PDT Tue Sep 6 2022 .SYNOPSIS... Near-record to record heat will continue through at least mid-week. Today will likely be the hottest day before we begin a gradual cooling trend into next week, though temperatures will likely remain above-average through early next week. Some isolated chances for showers and thunderstorms are possible this afternoon into this evening. Slight chances for showers and thunderstorms will continue each afternoon, with greatest chances for measurable precipitation this weekend. && .SHORT TERM... Unsurprisingly, the persistent ridge will enable record-breaking heat to continue through at least tomorrow. Hottest temperatures are expected today, with Reno potentially meeting a top-10 high temperature this afternoon of 105. Might I remind everyone that we entered meteorological fall last week, though I think Mother Nature missed the memo... Jokes aside, it looks like this prolonged heat event will finally begin to wind down beginning tomorrow. A shortwave trough will begin digging to our north tomorrow, subsequently flattening the ridge and commencing a gradual cooling trend through the remainder of the week. Temperatures will still remain near-record to record values tomorrow, though they will be a few degrees "cooler" than today. Satellite imagery currently shows cumulus clouds building over high terrain across the region, notably over the Eastern Sierra, Carson Range, and Pine Nut Mountains. Recent CAMs runs suggest that isolated showers and thunderstorms will develop early this afternoon over the Eastern Sierra, then track northward into far northeast CA and northwest NV by late evening. Blended guidance suggests greater and more widespread potential for isolated storms tomorrow afternoon. The greatest concern for any storms that develop include new fire starts from dry lightning, as storms look to produce little to no precipitation today and tomorrow. -Whitlam .LONG TERM... A slow cooldown is in store by the end of the week, albeit slow at first. High temperatures on Friday will still reach into the mid to upper 90s for the western NV valleys, with mid to upper 80s for the Sierra. Record high temperatures are still possible in Reno on Friday. The current forecasted high in Reno is 98 degrees, which would tie the old record for September 9th set last year. By the weekend into the beginning of next week, ensembles are coming into better agreement that moisture from the remnants of Hurricane Kay will lift northward into the region. This will drive anomalously high moisture content into western NV and the central Sierra. Current forecasted precipitable water values are between 0.8 to 1.0 inches, which will approach the 99th percentile maximum compared to climatology. At the moment, there is a 20 to 30 percent chance of mostly light showers for Friday and Saturday, with the chances of showers increasing on Sunday through next Tuesday. Current blended guidance indicates there is a 30 to 40 percent chance of showers in the Sierra and western NV, mostly south of Interstate 80. The threat of widespread thunderstorms during this time is low, primarily due to the extensive cloud cover which will limit the amount of convective potential. But, there is a slight risk of thunderstorms mostly in Mono/Mineral counties. Nonetheless, cloud cover will keep temperatures to more comfortable levels and finally near normal for this time of year. - McKellar && .AVIATION... Cumulus buildups along with isolated showers and thunderstorms are possible today, affecting all terminals through the afternoon. These storms will be capable of producing outflow winds in excess of 30+ kts. Otherwise, there will be typical afternoon breezes of 15-20 kts. High density altitudes are possible due to the very hot temperatures. For Wednesday, there is a 15-25 percent chance of showers and thunderstorms affecting a majority of the eastern Sierra and western NV. These storms are capable of strong outflow winds up to 40+ kts and heavy rain. Once again, all terminals can expect typical afternoon breezes with high density altitudes due to the continued hot temperatures. -McKellar && .FIRE WEATHER... Very hot temperatures, dry conditions, and typical afternoon and evening breezes will persist through Thursday. Primary change to the forecast will be for the potential for some stronger winds right along the Oregon/Nevada border with some localized critical conditions possible. Otherwise, the primary concern remains with the thunderstorm potential today through Thursday for the Tahoe Basin and Sierra Front southward into the Eastern Sierra. For any storms that initiate, they will be drier in nature, leading to increased risk of fire starts and gusty outflow winds. Today there are slight chances for showers and thunderstorms with localized gusty outflow winds to 40 mph. Thunderstorm coverage and potential will be higher on Wednesday and Thursday, with the potential for stronger gusty outflow winds potentially up to 50 mph. There is potential for residual tropical moisture to make its way into the region this weekend into early next week which will allow for conditions to cool off a bit and more widespread showers as well. -Edan && .REV WATCHES/WARNINGS/ADVISORIES...
