The episode as NWS SGF wrote it up.
A southward shift in the Westerlies forced a slow moving front to move southeastward into the Ozarks Region on the 8th. The front then stalled and interacted with several upper level disturbances to produce heavy rainfall and severe storms over the area through the early afternoon of the 9th. The strongest storms occurred during the afternoon and evening of the 9th, producing widespread damaging wind gusts which blew down trees and powerlines, and hail to the size of ping pong balls. The hardest hit areas were along and south of Interstate 44 from Joplin to Springfield to south of Lebanon. Rainfall accumulations of two to over four inches occurred from the Lake of the Ozarks to Stockton Lake and then southward toward Springfield, Mount Vernon and Neosho.

NWS Springfield, MO wrote its last area forecast discussion before the first event at Aug 8, 11:38 AM CST, 22 minutes earlier.
Area Forecast Discussion...UPDATED National Weather Service Springfield MO 1238 PM CDT Mon Aug 8 2022 Key Messages: 1. Scattered showers and thunderstorms today. Isolated gusty downburst winds and localized flash flooding will be the main hazards this afternoon/evening. 2. Continued unsettled weather through Tuesday and into Wednesday as the front stalls over the region. 3. Slightly less hot the first half of the work week with cloud cover and precipitation overhead. 4. Mostly dry forecast the second half of the week with more uncertainty in the temperature forecast. .SHORT TERM...(Today) Issued at 318 AM CDT Mon Aug 8 2022 Looking at current water vapor imagery, we can observe weak upper-level low pressure residing over the Missouri Bootheel region and a shortwave trough over the Northern Plains that will push eastwards into the Great Lakes region today. An associated cold front currently located along a line from central Iowa to far northwest Missouri to northern Kansas will dig southward into the SGF forecast area later today and begin a period of unsettled weather over the Missouri Ozarks. A few isolated showers and thunderstorms may arrive as soon as this morning over the northwestern portions of the CWA as the front approaches. Greater convective coverage should materialize this afternoon as moisture availability and instability increases. Modeled RAP analysis suggests an environment marked with 1500-2500 J/kg MLCAPE and PWATs in the 1.8-2" range overspreading the area this afternoon and evening. Depending on the degree of diurnal heating and subsequent steepness of low-level lapse rates, a few areas of isolated gusty downburst winds under the strongest updrafts cannot be ruled out. With weak effective bulk shear, widespread severe weather and organized storm structures are not expected. The more robust storm cells will be capable of heavy rainfall, so we will also need to monitor a localized flash flooding threat. As cloud cover increases today, we will likely see temperatures reaching the upper 80s to mid 90s this afternoon. .LONG TERM...(Tonight through Sunday) Issued at 318 AM CDT Mon Aug 8 2022 As this frontal zone stalls near southern Missouri, multiple rounds of precipitation will be possible tonight into Tuesday and extending into Wednesday. A series of upper-level vorticity maximums will also help to enhance lift during this time period. Confidence is on the higher end that a widespread 0.25"-0.75" of rainfall will be observed across most of the area through Wednesday. With a moisture rich atmosphere overhead and relatively weak mean flow and cloud-layer winds, training/slow-moving storms may lead to isolated heavier rainfall amounts and a localized flash flooding threat primarily along and south of the I-44 corridor. 00Z HREF ensemble probability matched-mean and ensemble max products highlight the potential for isolated areas of 2+ inches through Wednesday. Increased cloud cover and precipitation will keep temperatures in the mid 80s to low 90s Tuesday and Wednesday. Mid- and upper- level flow will begin to push a drier airmass into the region during the day Wednesday diminishing rain chances and keeping any convection constrained near the Missouri-Arkansas border and south. By Thursday, surface high pressure pushes into the region with the upper-level ridge building back over the Central Plains towards the end of the week. This will allow for a drier second half of the week. Winds will turn more southerly by the weekend with a gradual warm-up looking more probable. There are some signals that the Eastern Ozarks region may stay in more easterly surface flow which could allow for slightly cooler temperatures east of Highway 65 (temps in the 80s) and warmer temperatures over southwestern Missouri and southeastern Kansas (temps in the 90s) towards the end of this work week and into this weekend. The latest Climate Prediction Center outlook favors above-average temperatures and below-average precipitation later this weekend and into next week. && .AVIATION...(For the 18Z TAFS through 18Z Tuesday afternoon) Issued at 1235 PM CDT Mon Aug 8 2022 VFR conditions are expected through the TAF period, outside of any scattered thunderstorms. Thunderstorms will develop this afternoon and continue through the evening. They will be very scattered in nature and hard to pinpoint where they will occur. Have carried VCTS and Prob30s for now however amendments are possible. Gusty winds are likely under any thunderstorm. Winds will remain out of the south to southwest through the period, turning more northerly by the end of the TAF period and beyond. && .SGF WATCHES/WARNINGS/ADVISORIES... MO...NONE.
