The episode as NWS HUN wrote it up.
Clusters of strong to severe thunderstorms developed during the afternoon hours in western and middle Tennessee and dropped south into north Alabama.
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 7, 2:34 PM CST, 43 minutes earlier.
Area Forecast Discussion National Weather Service Huntsville AL 334 PM CDT Wed Aug 7 2019 .NEAR TERM...(Tonight) Issued at 334 PM CDT Wed Aug 7 2019 For the remainder of the afternoon, we anticipate clusters of convection extending from the TN Valley northwestward into the Ozarks region to continue tracking southeastward across the local area. Although this activity will remain most concentrated in the vicinity of a subtle low-level convergence boundary (likely a remnant outflow boundary from last night's MCS), we have indicated likely POPs for all forecast zones during the late afternoon hours. Environmental conditions are favorable for strong-marginally severe storms, based on deep-layer bulk shear of 30-35 knots and MLCAPE in the 3000-4000 J/kg range in areas that continue to experience strong insolation. Based on simple extrapolation, we will maintain likely POPs for the southeastern portion of the forecast area immediately after sunset, with current activity expected to largely dissipate by 02-03Z. However, latest near term guidance continues to suggest renewed development of convection across the MO Valley region late this afternoon/early this evening, likely initiated by outflow from storms in that region earlier today. This cluster of showers and thunderstorms is predicted to organize into another MCS, which will track rapidly southeastward -- potentially impacting the northwestern portion of the CWFA before sunrise tomorrow morning. In the interim period, patchy fog may develop late this evening, especially in areas that experience heavy rainfall later today. Lows will be quite mild and in the l-m 70s. .SHORT TERM...(Thursday through Saturday) Issued at 334 PM CDT Wed Aug 7 2019 Overall, we anticipate little change in the synoptic flow pattern during the period from Thursday-Friday, as the region will remain beneath moderately strong northwest flow along the northeastern edge of a 500-mb anticyclone centered across the southern Plains. Similar to today, it appears as it we may see a temporary lull in the coverage of showers and thunderstorms late Thursday morning/early Thursday afternoon, before scattered convection redevelops in the vicinity of a subtle low-level streamline confluence axis draped across the CWFA. Although morning cloud cover will likely limit instability compared to today (MLCAPE progged to be in the 1500-2500 J/kg range), bulk shear will still be supportive of storm organization and perhaps some brief strong wind gusts/small hail with the most intense cores. A consensus of short term NWP guidance continues to suggest that a pronounced mid-level shortwave disturbance will dig southeastward from the MO Valley into the mid- South region Thursday night, before crossing our region Friday morning. Stronger synoptic scale forcing for lift associated with this wave will contribute to a fairly widespread coverage of showers and thunderstorms during this period, with instability/shear parameters suggesting the threat for a few strong but sub-severe storms. Deep-layer flow will veer to the north-northwest and diminish considerably from Friday afternoon-Saturday, as the mid- level disturbance shifts southeastward off the Atlantic coast. This will allow for drying of the vertical column as confirmed by trends in precipitable water values, and we have lowered POPs into the low chance range both periods. Due to little fluctuation in the thermal properties of the boundary layer, max temps will be dictated by clouds/precipitation, with Friday expected to be the coolest period featuring highs in the m-u 80s. Lows will remain in the l-m 70s each morning. .LONG TERM...(Saturday night through Tuesday) Issued at 334 PM CDT Wed Aug 7 2019 Models dissipate the afternoon activity on Saturday night very early in the evening. As a surface high and a very warm upper ridge builds into the area on Saturday precipitation should be well south and east of northern Alabama and southern middle TN. Very warm 925 mb temperatures between 25 and 27 degree are shown in most guidance. This along with abundant sunshine should allow highs to climb into the mid 90s at the very least. The airmass advecting into the region on the east side of this upper level ridge should keep very humid conditions in the forecast. Heat index values should climb back into the 100 to 104 degree range again. This pattern doesn't change much through Wednesday night, as the upper ridge edges closer to the Tennessee Valley, but never really builds over it. This will keep northern Alabama and southern middle Tennessee in northwest flow aloft, keeping on and off chances of showers and thunderstorms in the forecast. A moist and very unstable airmass will remain in place, so additional strong thunderstorm activity will remain possible. Heavy rainfall and some flooding may become an even more widespread concern Tuesday into Wednesday, as a decent front for this time of year pushes into the area via NW flow. && .AVIATION...(For the 18Z TAFS through 18Z Thursday afternoon) Issued at 1255 PM CDT Wed Aug 7 2019 Latest visible satellite imagery and sfc observations confirm VFR conditions at the MSL/HSV terminals early this aftn, with sct layers of cu/ac slowly developing beneath a bkn deck of cirrus. However, we expect fairly rapid development of convection to occur btwn 18-21Z, in the vicinity of a NW-to-SE oriented low-level convergence boundary bisecting the region. Storms should track southeastward and could become quite numerous and strong, due to a favorable combination of instability and wind shear. Thus, we have included TEMPO groups for TSRA and MVFR cigs/vsbys at both airports btwn 21-24Z. Although lingering SHRA may continue invof the terminals early this evening, we have removed TSRA from the TAFs after 00Z, but this may need further evaluation based on radar trends. Patchy BR/FG may also develop in portions of the area btwn 04-13Z, but with expected coverage of bkn-ovc mid and high-lvl clouds, we will not include in the forecast at this point. Sct cu field should redevelop by the end of the TAF period, with WSW flow increasing to 5-10 knots once again. && .HUN WATCHES/WARNINGS/ADVISORIES... AL...NONE.
