The episode as NWS OHX wrote it up.
Thunderstorms developed ahead of a cold front that moved eastward through Middle Tennessee on September 24, 2024. With plenty of instability and wind shear, these thunderstorms strengthened and became severe through the afternoon and evening. Damaging winds were the primary threat with numerous reports of downed trees and powerlines received. The most significant damage was reported in Ethridge where severe winds caused a tent to collapse, injuring three people. Some hail reports were received as well, but these were mostly less than one inch in diameter.
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 Nashville, TN wrote its last area forecast discussion before the first event at Sep 24, 12:12 AM CST, 4 hours 4 minutes earlier.
Area Forecast Discussion National Weather Service Nashville TN 112 AM CDT Tue Sep 24 2024 ...New SHORT TERM, LONG TERM... .SHORT TERM... (Today through Tonight) Issued at 109 AM CDT Tue Sep 24 2024 Water vapor imagery this morning shows an upper-level trough digging into the Great Plains while surface obs reveal a cold front to our west over Missouri & Arkansas. As this front pushes into the area today, storm coverage will increase across Middle TN. With SBCAPE of 1500 to 2000 J/kg and bulk shear increasing to 30 to 40 knots, a few of these storms may become strong to severe this afternoon. Main risk will be gusty to damaging winds. Hail looks to be unlikely as lapse rates will be poor at less than 6 C/km. Main time frame for severe thunderstorm potential is between 1pm and 8pm. Meanwhile, temperatures will start to cool thanks to increased cloud cover and the rain. A few showers may linger overnight, especially across the Plateau where the cold front looks to stall. && .LONG TERM... (Wednesday through next Tuesday) Issued at 109 AM CDT Tue Sep 24 2024 A more active week is still on tap. Starting Wednesday, another upper-level low dives southward into northern Arkansas and stalls in this area through the weekend. Meanwhile, eyes are also on the tropics as PTC9 is forecast to strengthen over the eastern Gulf this week, eventually becoming Hurricane Helene. It's expected to make landfall on the Florida Panhandle Thursday, and then gradually weaken as it tracks northward into eastern TN Friday. Once the remnants of the tropical system move out the area, the low over AR will finally eject towards the northeast, clearing Middle TN by Monday or Tuesday. These two systems will bring rounds of rain to Middle TN through the remainder of this forecast period. Best chance for heaviest rainfall will be on Thursday & Friday thanks to the tropical moisture moving into the area, and with the track of future Helene to our east, it'll be eastern Middle TN that will be favored for the highest rainfall amounts this time. The latest rainfall forecast is still showing a general 2 to 4 inches through this upcoming weekend with higher amounts possible across the Plateau. Minor flooding could be a concern by week's end, but widespread flooding is currently not expected as the current drought status means that our rivers and creeks will have room for the welcome rain. But of course this forecast will continue to be refined as the future tropical system takes shape over the next few days so stay tuned. && .AVIATION... (06Z TAFS) Issued at 1241 AM CDT Tue Sep 24 2024 The 06Z TAFs are starting off VFR, but there is the possibility of some radiation fog at our eastern terminals (CSV, SRB) overnight. Meanwhile, an upper trough has set up west of Mississippi Valley, and a surface low pressure system is now developing near STL that is providing the focus for some ongoing convection in that proximity. The HRRR does show at least some scattered cells developing across Middle Tennessee toward morning, with more widespread convection expected this afternoon. && .PRELIMINARY POINT TEMPS/POPS...
