The episode as NWS SGF wrote it up.
Showers and thunderstorms developed ahead of a slow moving upper level disturbance that tracked eastward across the southern Plains into the lower and middle Mississippi Valley from the 2nd to the early morning of the 3rd. Several reports of flash flooding were received south of Highway 60 from Aurora and Cassville, and eastward toward Ava. Rainfall accumulations for the 24-hour period ending at 1 AM on 9/3/22 showed a large area of one to two inches along and east of a line from Joplin to Versailles, with greater than two inches along and south of a line from Monett to Mountain Grove. A few locations in Douglas County received over 5 inches of rain.

NWS Springfield, MO wrote its last area forecast discussion before the first event at Sep 2, 1:56 PM CST, 1 hour 4 minutes earlier.
Area Forecast Discussion National Weather Service Springfield MO 256 PM CDT Fri Sep 2 2022 Key Messages: 1. Localized flooding risk continues into this evening over far southern MO, generally south of Hwy 60. 2. Low rain chances this weekend into next week, but nothing prolonged or highly impactful, are expected for the next seven days. 3. Other than today's cooler temps, near average temps are expected for the next seven days. .SHORT TERM...(This evening through Saturday) Issued at 250 PM CDT Fri Sep 2 2022 The upper low continues to slowly progress eastward this afternoon. Moderate to locally heavy rainfall is being observed roughly along and south of Highway 60 where a Flood Watch remains in effect until midnight tonight. This is in response to the upper low, along with instability and ample moisture. As the upper low moves east late this evening into Saturday, precip will follow suit. By late tonight, only the southeastern CWA should be seeing any rainfall. Fog is expected late tonight into early Saturday, with potential for locally dense fog. For Saturday, look for low end chances for showers and storms over the far southeastern CWA and maybe some isolated showers across the far northwestern CWA. Elsewhere, look for generally clear skies. Highs Saturday will range from the upper 70s far east to the upper 80s far west. .LONG TERM...(Saturday Night through Friday) Issued at 250 PM CDT Fri Sep 2 2022 Expected Synoptic Pattern: Ensemble Cluster Analysis generally supports the mid level high remaining across the western US through the next week. This continues to leave our area susceptible to shortwave energy that could linger just east of the area or perhaps slide back west across the area. The upper low today may linger close enough to impact the area through the weekend, with additional waves dropping close by Tuesday and Wednesday of next week. The National Blend of Models daily high temp spreads are only about 5 degrees, which leads to high confidence in temperatures remaining about average for early September. Sunday and Monday: Shortwave energy just east of the area will give areas mainly east of Highway 65 a daily chance (20-40%) for isolated showers and storms. These would likely be diurnally driven and quite isolated with most locations remaining dry. Near normal temps are likely. Tuesday through Friday: We continue to see variance in the ensemble data towards the middle of next week. Ensembles are showing both location and timing issues with the upper level energy across the northern US during this time. This leads to lower confidence in the forecast. At this time near average temperatures and daily low rain chances persist. && .AVIATION...(For the 18Z TAFS through 18Z Saturday afternoon) Issued at 1234 PM CDT Fri Sep 2 2022 KSGF and KBBG: Widespread rainfall will continue into this evening before tapering off. Some thunder will be possible, especially at KBBG. Fog is expected to develop tonight. KJLN will be on the periphery of the area of rain, resulting in vicinity showers for a couple more hours. Fog is expected to develop tonight. && .SGF WATCHES/WARNINGS/ADVISORIES... MO...Flood Watch until midnight CDT tonight for MOZ095-096-102>105.
