The episode as NWS OHX wrote it up.
An abnormally dry August led to worsening drought conditions, especially across southwest Middle Tennessee. Precipitation totals were below average across the area with Middle Tennessee's climate stations reporting rainfall deficits of around 1.50 inches to nearly 3 inches for the month. For the Nashville area, August 2024 was the 11th driest August on record, and the summer of 2024 was the 17th driest summer on record. By the end of the month, about 40 percent of Middle Tennessee was in at least moderate drought conditions. Of this, about 18 percent was in at least severe drought status with about 8 percent in extreme drought.

Area Forecast Discussion National Weather Service Nashville TN 1221 AM CDT Tue Aug 27 2024 ...New AVIATION... .UPDATE... Issued at 751 PM CDT Mon Aug 26 2024 The forecast remains on track as temperatures cool for the night back into the 60s. Tuesday is still on track to be a hot one as temperatures approach 100 degrees, especially W of the Upper Cumberland. On the plus side, RHs will be below 40% making it a little more bearable. && .SHORT TERM... (Rest of today through Wednesday) Issued at 1130 AM CDT Mon Aug 26 2024 The hot pattern continues with very little change from our previous forecast. A very strong ridge centered over the Mid Ms Valley will move eastward through the next couple of days pushing temps upward a little each day. Widespread upper 90s will be reached west of the Plateau this afternoon. Many areas will reach 100+ Tuesday, and especially Wednesday which looks like the hottest day of the week. Strong subsidence under the ridge will keep the area rain-free and mostly cloud-free. Unfortunately, the hot and dry conditions will worsen drought levels across the area. Some good news is sinking air and diurnal mixing will keep dew points in check, so afternoon heat index values will not climb much above actual temps. At this time, we are not planning to issue any heat headlines for the next couple of days with heat index values staying below 105 degrees. If humidity trends increase or surrounding areas reach criteria, we could end up with an advisory for parts of our by midweek. && .LONG TERM... (Wednesday Night through next Monday) Issued at 1130 AM CDT Mon Aug 26 2024 The big ridge will start to break down after Wednesday, but at the same time, humidity levels will climb. This could give us some of the highest heat index values on Thursday with borderline heat advisory values. A stray shower or storm could bubble up Thursday afternoon, but better chances for scattered thunderstorms will come Friday as moisture begins to pool ahead of an approaching front. Scattered storm chances will continue into the weekend as the weakening surface oozes across the area. Sadly, only meager rainfall amounts are expected. Temperatures this weekend will not be as hot with highs dropping back into the mid 80s to lower 90s. The longer range outlook for next week shows temps settling to normal August levels with better rain chances than this week, but no "drought busters". && .AVIATION...
