The episode as NWS OHX wrote it up.
An isolated thunderstorm moved across far northwest Middle Tennessee during the late afternoon of April 8, 2024. With abundant instability, this thunderstorm became severe in west Tennessee before crossing the Tennessee River. Reports of large hail up to 1.5 inches were received along with damage due to strong winds across portions of Houston and Stewart counties.

Area Forecast Discussion National Weather Service Nashville TN 1225 PM CDT Mon Apr 8 2024 ...New AVIATION... .SHORT TERM... (Rest of today through Tuesday) Issued at 1100 AM CDT Mon Apr 8 2024 Showers and a few thunderstorms this morning continue for areas along and near the Cumberland Plateau. This activity should be exiting the area by noon, and while most will remain dry through the remainder of the day, we are still expecting some pop-up hit- and-miss thunderstorms. While CAPE values are expected to rise to around 500-1000 J/kg this afternoon with a destabilizing atmosphere - especially across west TN - CAMs aren't really latching onto much happening this afternoon. Shear isn't great at less than 50 knots. So while I won't rule out a stray strong storm this afternoon that manages to produce small hail or gusty winds, do think that these will be more pulse-like storms that will struggle to sustain themselves. Organized severe weather is not expected. As for the main event today, satellite imagery does show some breaks in the clouds across western Middle TN! Trying to stay cautiously optimistic that we'll still get a glimpse of the eclipse this afternoon. Fingers crossed. Next round of rain moves into from the southwest after midnight and will spread northward through early Tuesday morning with widespread showers and a few thunderstorms expected. Atmospheric profiles become saturated with PWATs rising to 1.25 to 1.35 inches which is above the 90th percentile for the date. Due to this, CAPE values fall with probabilistic guidance showing a very low chance (10 percent at best) of seeing CAPE values above 100 J/kg. So no severe weather expected, but may have to keep an eye on any flood- prone locations or low-lying areas for minor flooding. && .LONG TERM... (Tuesday Night through next Monday) Issued at 1100 AM CDT Mon Apr 8 2024 By Tuesday night and into Wednesday, a deep upper-level low digs into the Red River area while the surface low deepens over Arkansas. This keeps our unsettled pattern continuing with additional rounds of rain on Wednesday. With this upper-level and surface low, dynamics are better for thunderstorm development, however, all model guidance continues to show the better instability and shear to our south. Our far southern counties may need to be watched for a stray strong storm Wednesday where the current SPC Day 3 Outlook has a marginal risk in place. However, the threat for severe weather is low. Wednesday night and into Thursday, the upper-level and surface low eject towards the northeast, and this rain will gradually come to an end by late Thursday. By the end of this rainy stretch, about 2 to 4 inches of rain is expected with the higher amounts expected for locations nearest the Tennessee River. As the week progresses and these amounts add up, there may be minor flooding issues, especially along our area creeks and rivers. Upper-level ridging builds in this weekend, resulting in a beautiful weekend! Conditions will be dry and sunny with highs getting close to 80 by Sunday. && .AVIATION... (18Z TAFS) Issued at 1216 PM CDT Mon Apr 8 2024 Although most of the earlier showers have departed Middle Tennessee, there will still be a few echoes left over for the afternoon. Also look for TEMPO MVFR clouds the next couple of hours, although ceilings overall have improved. A warm front will lift northward across the mid state late tonight and early tomorrow, so look for showers to redevelop before sunrise, with ceilings dropping to MVFR and even IFR at times. Surface winds will be gusty again tomorrow. && .PRELIMINARY POINT TEMPS/POPS...
