The episode as NWS OHX wrote it up.
Numerous showers and thunderstorms spread across Middle Tennessee during the afternoon and evening hours on July 6. Several reports of wind damage and one report of flooding were received.
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 Jul 6, 1:58 PM CST, 1 hour 29 minutes earlier.
Area Forecast Discussion National Weather Service Nashville TN 258 PM CDT Thu Jul 6 2017 .DISCUSSION... It's relatively quiet, comparatively speaking, at forecast time for Middle TN. Between yesterday's activity and this morning's batch of showers and thunderstorms across the south, we are really wet -- and this could factor into the forecast this evening. Skies cleared out for everyone late this morning, which has allowed the sun to warm us up quite a bit. Mid to upper 80s are being seen just about everywhere. Combined with dew points in the low 70s, we are having a very muggy day out there. The other result is surface based CAPE values of 3000+ J/Kg. This level of instability is expected to fuel yet another round of showers and thunderstorms late this afternoon and this evening as yet another shortwave brings us more atmospheric energy for convection. We're already seeing pretty decent thunderstorm coverage just north of the TN/KY state line and it's this activity, and more that will form upstream of it, that will keep us busy this evening. Shear values aren't out of control, so that's good news. Bulk values of 25-30 kts should limit organization. Of more importance is the way the boundary layer winds are setting up for this evening. Mean 850mb layer flow would suggest more of a training situation for Middle TN, so while the severity may not be of huge concern, those areas that have seen the bulk of the rain over the last 24-36 hours will need to be extra vigilant as storms begin this evening as localized flash flooding may rear its head. Storms should begin to wane as we near the midnight hour and we lose the heating of the day. After rains come to an end, patchy dense fog could become an issue after midnight, so keep this in mind for the Friday morning commute. Friday should be dry. While this will be a nice break from all of the rain we've had, it's not going to do us any favors in the temperature category. Highs are likely to climb near 90 and dew points will remain in the low 70s. This means Heat Index values in the mid 90s, so prepare for a scorcher. Another shot at some rain returns Friday night as a "front" moves through the region, however, I'm not crazy about high chances of rain. Latest guidance comes in with very little QPF and there isn't any forcing along this boundary, so while there's a small chance, I don't think everyone sees rain Friday night. These small chances will exit Saturday morning and some relief from the high dew points will move into the area, especially Saturday night and Sunday. Low 60s dew points will be a welcomed mid-summer treat. Sunday and Monday should be dry rain-wise. Rain chances will start to creep back into the forecast on Tuesday afternoon and persist each afternoon through the remainder of the week. These will be diurnal thunderstorms, so afternoon and early evening chances each day will return with temperatures right around normal. && .AVIATION... 18Z TAF DISCUSSION. Chances for additional showers and thunderstorms will impact all terminals this afternoon and into the early evening. Timing and coverage are both difficult today with the isolated nature of convection forming early this afternoon. Used consensus mainly of short term models to get the best idea on timing. Mainly looking at the 18Z-00Z timeframe for KCKV, 21Z-03Z for KBNA and KMQY, and similar for KCSV. Models also show some lower cigs moving in overnight into the early morning, with some fog possible as well. Have MVFR cigs/vis for now with the exception on KBNA/KMQY where MVFR cigs are forecasted but not vis. Models also show that even IFR cigs will be possible, especially at KCSV, but kept in low MVFR for now to see if model runs continue to show lower cigs. && .PRELIMINARY POINT TEMPS/POPS...
