The episode as NWS HUN wrote it up.
Clusters of thunderstorms developed around midday in north central Alabama, expanding in coverage and intensifying through the afternoon. These were pulse-type summertime thunderstorms, with very heavy downpours in a short period of time, leading to ponding of water. One of the thunderstorms produced half dollar sized hail in eastern Limestone County.
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 Huntsville, AL wrote its last area forecast discussion before the first event at Aug 6, 2:28 PM CST, 4 minutes earlier.
Area Forecast Discussion National Weather Service Huntsville AL 328 PM CDT Sat Aug 6 2022 ...New NEAR TERM, SHORT TERM, LONG TERM... .NEAR TERM... (Tonight) Issued at 328 PM CDT Sat Aug 6 2022 Isolated to scattered convection continues to develop underneath a weakening upper level ridge centered over northeastern Tennessee and southwestern Virginia. SBCAPE, MUCAPE, and low level lapse rates are conducive for a few strong storms that could produce frequent lightning, wind gusts to 50 mph, and heavy downpours this afternoon into the early evening hours over northern Alabama and southern middle Tennessee before dissipating. Clearing late this evening and overnight should allow temperatures to drop into the lower 70s. At this time, winds should stay up enough outside of valley locations to keep fog at bay. However, in sheltered valley locations, some patchy fog could occur towards day break on Sunday. && .SHORT TERM... (Sunday through Tuesday) Issued at 328 PM CDT Sat Aug 6 2022 Expect scattered showers and thunderstorms to continue on the west side of the weakening upper ridge on Sunday through Tuesday as well. Some models hint at a prefrontal toughs axis focusing some more widespread precipitation chances on Monday. Again, instability and DCAPE values look high enough for a continued threat of strong thunderstorm capable of producing winds gusts around 50 mph, frequent lightning, and locally heavy rainfall. We will have to watch for the potential for some minor localized flooding occurring during that period. There should be enough morning sunshine for highs to reach the 90 to 95 degree range in some locations west of the I-65 corridor through Monday. Tuesday may be a tad cooler than that. && .LONG TERM... (Tuesday night through Saturday) Issued at 328 PM CDT Sat Aug 6 2022 Tuesday night a strong front is shown pushing south into northern Alabama. This front very slowly moves southeast and keeps much of the area wet through Thursday. This should keep highs a bit cooler than earlier in the week, for now only have highs reaching the mid 80s to around 90 degrees. It will remain humid though. Flooding may become more of a widespread issue during that period. A break in the rainy pattern returns briefly Saturday night into Sunday night. However, GFS puts the area more in northwesterly flow and brings disturbances into the area early next week. ECMWF keeps the overall eastward extension of the upper ridge centered over Kansas and Oklahoma areas. So for now stuck close to a blend of data, keeping isolated to scattered showers and thunderstorms in the forecast. It should be a bit warmer with more sunshine expected with highs climbing back into the upper 80s to lower 90s. && .AVIATION... (18Z TAFS) Issued at 1249 PM CDT Sat Aug 6 2022 VFR conditions are expected to be predominant at both TAF sites through the TAF period. However, included VCTS at both sites this afternoon. At KHSV, have higher confidence that -TSRA could directly impact that terminal between 22Z and 01Z with some MVFR conditions. Expect this activity to end early this evening at both terminals. && .HUN WATCHES/WARNINGS/ADVISORIES... AL...None. TN...None. && NEAR TERM...KTW SHORT TERM....KTW LONG TERM....KTW AVIATION...KTW

Isolated to scattered thunderstorms will be possible before dissipating early this evening. A few of these storms could be strong with gusty winds of up to 50 mph. .DAYS TWO THROUGH SEVEN...Sunday through Friday. Scattered to possibly numerous thunderstorms are forecast each day through Thursday, with storm coverage highest during the afternoon and early evening hours. Due to the slow-moving nature of the thunderstorms, locally heavy rainfall will be the primary risk. A few stronger storms could produce wind gusts up to 50 mph and frequent lighting. .SPOTTER INFORMATION STATEMENT... Spotter activation is not expected at this time. 20
