The episode as NWS HUN wrote it up.
A complex of thunderstorms dropped southeast into north Alabama from middle and western Tennessee during the midday hours. A well defined gust front pushed south from these thunderstorms producing strong and gusty winds. A couple of trees were knocked down as a result in Colbert County.

Area Forecast Discussion National Weather Service Huntsville AL 1138 AM CDT Sun Sep 1 2024 ...New AVIATION... .NEAR TERM... (Rest of Today) Issued at 1025 AM CDT Sun Sep 1 2024 Over the course of the day, the general synoptic weather pattern across the TN Valley will become increasingly influenced by an amplifying longwave trough extending from eastern Canada southward into the Great Lakes and northeastern CONUS. As this occurs, mid- level flow will gradually veer from WSW to WNW, supporting a more pronounced southeastward storm motion compared to the weak steering currents we have experienced the past couple of days. If sufficient breaks in the overcast altostratus layer can occur later this morning to permit weak destabilization of the local boundary layer, then a few thunderstorms could develop as early as 16-18Z (primarily north of the TN River). However, the most likely scenario is that clusters of convection, currently in progress along a pre-existing surface trough/remnant cold front extending from northern AR into the central Appalachians, will spread southeastward with time as this boundary is overtaken by a stronger cold front extending southwestward from a deepening low over Quebec. Present indications are that this activity will impact our CWFA during the afternoon hours before exiting early this evening. As alluded to earlier, storm intensity will be dictated by the amount of insolation realized prior to the arrival of convection, but at this point forecast soundings depict weaker low-level lapse rates and CAPE (1000-1500 J/kg) compared to previous days, as high temps may only reach the m-u 80s. If this is indeed the case, the risk for microbursts will be lower, but frequent lightning and locally heavy rainfall may still occur in the most intense cells. && .SHORT TERM... (Tonight through Wednesday) Issued at 147 AM CDT Sun Sep 1 2024 After the aforementioned cold front moves through, dry air is forecast to move in behind it as sfc high pressure filters in from the north. This will be short-lived as low to medium chances (20-40%) of shower/storms return Tuesday and Wednesday due to a series of upper level shortwaves forecast to move across the TN Valley. During this time, highs are forecast to begin a cooling trend for the remainder of the week as the effects of the cold front are felt with highs reaching the mid 80s to low 90s Tuesday then peaking in the low 80s Wednesday. A low chance of fog exists at the end of the TAF period, however, confidence is too low to include it in the TAF at this time. && .LONG TERM... (Wednesday night through Saturday) Issued at 147 AM CDT Sun Sep 1 2024 The medium range models differ late next week, mainly due to timing and the corresponding rain chances. The ECMWF is forecasting a shortwave in the Ozarks through TX to shift slowly east. This produces widespread precipitation (both warm and cool sector) as moist southerly low level flow develops in advance of the trough. The GFS is slower, and also keeps a deeper low level ridge and dry/stable airmass more locked into the southeast U.S. This would delay the onset of precipitation until Day 5. In any event, there is a bit more agreement on the 00Z GFS run with the previous ECWMF. The NBM keeps a wetter trend going and will not divert at this point. Temperatures will be near or slightly below normals, with highs in the lower to middle 80s and lows mainly in the 60s. && .AVIATION... (18Z TAFS) Issued at 1138 AM CDT Sun Sep 1 2024 Prevailing conditions will remain VFR at the HSV/MSL terminals this aftn, with gradual development of few-sct stratocu and high- based Cu anticipated beneath a broken layer of As. However, SHRA/TSRA occurring along a prefrontal sfc trough will spread southeastward with time (from western/Middle TN), and may impact the terminals btwn 19-23Z. TEMPO groups for MVFR cig/vsby reductions have been included during this timeframe, and AWWs for lightning may be required as well. Lingering precipitation will spread southeastward and diminish btwn 0-3Z, with a notable clearing trend expected by 2Z, followed by SKC conds around 9Z. This, coupled with abundant boundary layer moisture and generally light winds will set the stage for early development of BR/FG (some of which could become locally dense and result in IFR vsby reductions btwn 9-14Z). Fog will lift/scatter by 14Z as NE flow strengthens, with a few fair-weather Cu possible toward the end of the TAF period. && .HUN WATCHES/WARNINGS/ADVISORIES... AL...None.
