The episode as NWS REV wrote it up.
An upper low that settled over southern NV/UT encouraged the return of greater thunderstorm coverage during this period with near severe storms bringing heavy rain and flash flood concerns to the region. These strong storm cells also brought along gusty, erratic winds, small hail, and plenty of lightning. Slightly below normal temperatures continued before returning to near normal the middle of upcoming week.
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 Jun 10, 12:52 PM PST, 2 hours 8 minutes earlier.
Area Forecast Discussion National Weather Service Reno NV 152 PM PDT Sat Jun 10 2023 .SYNOPSIS... Widespread thunderstorm coverage returns today through Monday, with elevated concerns for flash flooding areawide. Storms through Monday are capable of producing heavy rainfall, frequent lightning, small hail, and gusty outflow winds as well. Thunderstorm chances will become more isolated from Tuesday onward. && .DISCUSSION... Another active day is in store today, with showers and thunderstorms already ongoing early this afternoon. Coverage is gradually increasing northward as moisture rides up the eastern periphery of a closed low swinging into southern California today. Storms will be more organized today in comparison to yesterday's pulse storms, with increasing flow aloft leading to enhanced shear and instability across the region. The main threat today will be flash flooding, as soils are already saturated and many area creeks and streams are running high. As such, it won't take significant accumulation for flash flooding to occur; if recreating outdoors today, have a plan to quickly reach safety. Other than flooding, all typical thunderstorm threats are possible today, including heavy rainfall, frequent lightning, gusty winds to 50 mph, and small hail. Current satellite imagery indicates drier air over northern Lassen and Washoe counties, perhaps indicating these areas may observe locally stronger outflow winds later this afternoon. The aforementioned closed low will propagate eastward Sunday into Monday and introduce even more moisture and instability to our region. Storm motions on Sunday and Monday will be slower in comparison to today, leading to even more concern for flash flooding areawide. Easterly steering flow will focus higher liquid totals across the Sierra, far western Nevada, and northeast California. ECMWF EFI guidance continues to highlight these areas on Sunday- Monday, with the QPF forecast around the 85th percentile of climatology. The main low will exit the region by Tuesday, but a weaker area of low pressure looks to remain anchored off the SoCal coast. A ridge building to the north of the low will introduce drier northwesterly flow to the region on Tuesday. This won't completely squash thunderstorm chances, however, as we will still lack large scale subsidence. Therefore, isolated thunderstorms are expected to develop each afternoon, mainly focused along the Sierra and areas south of US-50. More zonal flow over the western US from Tuesday onward will enable temperatures to moderate back to seasonal averages after a long stretch of below average temps. Expect highs in the mid-80s for western Nevada valleys and 70s for Sierra valleys through Friday. -Whitlam && .AVIATION... * An active thunderstorm pattern is expected at least through Monday with a a higher likelihood of MVFR-IFR conditions and heavy raining storms. Anticipate a 50-80% chance for thunderstorms at any given location each afternoon and evening, with chances for showers continuing overnight, especially Sunday night into Monday. * As of 1pm this afternoon, storms have initiated along Mono, S.Lyon and Mineral counties. Expect this activity to expand northward to include KRNO/KNFL/KCXP/KSVE beginning around 22z. Showers may linger through 07z tonight. * Otherwise, there remains chances for shallow, patchy fog through the Martis Valley, including KTRK, from approximately 10z-15z. The highest likelihood will be following recent rainfall and if skies clear overnight. -Dawn/TF && * Flash flooding is the primary concern with potential for heavy rain and slow moving storms through Monday. Areas that are particularly prone are recent burn areas and creeks and streams already near bankfull with ongoing snowmelt, but flash flooding may not be limited to these areas. Keep in mind that hydrologic modeling for rivers cannot fully account for the convective precipitation anticipated with storms. * A strong thunderstorm has produced heavy rainfall across far SE Lyon county this afternoon with upwards of 1.25-1.75" of rain estimated via radar across higher terrain southwest of E.Walker road. This may also result in bump in flows across the east fork of the Walker River this afternoon. * Otherwise moderate flooding continues along the Walker near Mason and is expected to stay fairly level through the weekend outside of added runoff from localized thunderstorms. The earlier crest at Wabuska will take a day or two to reach Weber Reservoir. Additional future rises along the Walker are likely with prolonged flooding expected to last into July. * High flows to continue along the west fork of the Carson, but the current forecast keeps the rivers below flood stage. Minor flooding is ongoing along the lower Humboldt at Imlay with a few inches of water flowing over Tungsten Road. Flows at Imlay are expected to rise slightly into next week, remain in minor flood stage, before very slowly receding. * Creeks and streams areawide will continue to run high, cold, and fast; with some potentially out of banks especially throughout portions of Mono County. As a result, banks may be unstable and any debris can send flows into unexpected areas, so take caution near waterway edges. -Bardsley/Fuentes && .REV Watches/Warnings/Advisories... NV...None.

Storms will favor the afternoon and evening hours, with chances for showers to continue overnight. * While the typical thunderstorm threats are on the table, such as frequent lightning, up to nickel size hail, and erratic wind gusts up to 50 mph, which could kick up areas of blowing dust; the main concern will be heavy rainfall. The threat for flash flooding exists, especially for recent burn scars and steep terrain. If a nearby stream rises quickly or the water becomes turbid with mud or debris, get to higher ground immediately. Urban flooding is also a possibility given the antecedent conditions and potential rainfall rates. * If you have outdoor plans be sure to have a "plan B". Make sure to have a way to seek shelter within a sturdy building in case a thunderstorm forms nearby. If you do not have access to a sturdy building, a hard-topped vehicle with the windows rolled up is a good protective option from lightning. The preferred time for completion of outdoor activities will be the morning prior to the development of afternoon and evening thunderstorms. http://weather.gov/reno
