Multiple clusters of strong thunderstorms developed during the mid afternoon hours and moved east-southeast across north Alabama. One of the thunderstorms produced a wind gust of 52 mph in Muscle Shoals, which knocked down at least one tree in the area.

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 Sep 6, 10:44 AM CST, 2 hours earlier.
Area Forecast Discussion National Weather Service Huntsville AL 1144 AM CDT Tue Sep 6 2022 ...New AVIATION... .NEAR TERM... (Rest of Today) Issued at 940 AM CDT Tue Sep 6 2022 A positively-sheared mid/upper-level trough axis will continue to progress southeastward into the Mid-South and Lower OH Valley regions today, maintaining modest west-southwesterly flow aloft of 15-25 knots across the TN Valley. Abundant deep-layer moisture will exist in this regime as precipitable water values should remain in the 1.6-1.8 inch range, and this will support the development of scattered showers and thunderstorms this afternoon. Present thinking is that convection will begin to develop between 18-20Z as the current layer of low stratus clouds disperses, allowing for modest warming and destabilization of the boundary layer ahead of a weak cold front/wind shift axis associated with the upper trough. Should sufficient warming occur (max temps in the mid-upper 80s) to support MLCAPE in the 1500-2000 J/kg range, a couple of wind gusts in the 40-50 MPH range may occur with the stronger thunderstorms. Otherwise, lightning and locally heavy rainfall/flash flooding will be the main concerns. && .SHORT TERM... (Tonight through Friday) Issued at 220 AM CDT Tue Sep 6 2022 The weak front may then begin to drift towards the south, as the upper trough axis moves eastward into the mid Atlantic/central Gulf states. Rainfall likewise may begin to translate more S/E, as slightly drier air filters into the area from the north. Areas of locally dense fog are once again possible tonight, given the light winds/saturated ground. Iso/sct showers/tstms are also possible during day Wed before the brief influx of drier air lowers rain chances even more Wed night thru Thu night. Highs Wed/Thu look to climb into the mid 80s for most spots, with lows in the 60s. The latter half of the global models are then suggesting the upper trough pattern closing off over the central Gulf region on Fri, as another upper trough out of the NW dives SE into the mid/upper Plains states. With the weak front also meandering in the general area, showers/tstms will increase by the end of the work week. Afternoon temps Fri will also trend a bit cooler, with highs more in the lower 80s/near 80F. && .LONG TERM... (Friday night through Monday) Issued at 220 AM CDT Tue Sep 6 2022 The upper trough/low over the central Gulf region will weaken and move to the east, as the second upper trough/low out of the Plains dives more into the Midwest states. This should allow for sct/num showers/tstms continuing this weekend, before rain chances fall Sun night into Mon, as the upper low/trough pushes more into the OH Valley. Locally heavy rainfall will again be possible with some storms and may result in some minor flooding issues in areas that receive multiple episodes of heavy rain. Highs thru the end of the period look to remain in the lower 80s/near 80F, while lows trend mainly in the mid/upper 60s. && .AVIATION... (18Z TAFS) Issued at 1144 AM CDT Tue Sep 6 2022 Current satellite data indicates that the residual MVFR stratus layer will continue to gradually lift this aftn, with VFR cigs in the 3.5-6 kft layer expected to return to both terminals by the beginning of the valid TAF period. Sct SHRA/TSRA are expected to develop in the moist airmass as the stratus disperses, allowing for modest warming/destabilization of the boundary layer. Thus, we have indicated VCSH thru 00Z at both terminals, along with TEMPO for TSRA btwn 18-22Z/MSL and 20-24Z/HSV. Additional convection may develop to our north this evening as a weak cold front advances southeastward into Middle TN, but there is too much uncertainty regarding its southward extent to include additional storms in the forecast attm. The combination of partial clearing, light winds and abundant sfc moisture will allow for BR/FG development once again btwn 4-8Z, with significant vsby reductions to IFR/LIFR possible btwn 8-12Z. Sfc winds will veer to NNW late in the period. && .HUN WATCHES/WARNINGS/ADVISORIES... AL...None. TN...None. && NEAR TERM...70/DD SHORT TERM...09 LONG TERM...09 AVIATION...70/DD
