The episode as NWS MRX wrote it up.

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 Morristown, TN wrote its last area forecast discussion before the first event at Jun 3, 1:47 PM EST, 1 hour 53 minutes earlier.
Area Forecast Discussion National Weather Service Morristown TN 247 PM EDT Sun Jun 3 2018 .SHORT TERM...(Tonight and Monday)... The focus of the short-term forecast will be on the cold front approaching from the west. Current radar imagery indicates a line of showers and storms developing along this boundary across the Cumberland Plateau. Temperatures are in the the low to mid 80s with dewpoints in the upper 60s and low 70s, producing SBCAPE values of 1500-2500 J/Kg across the region. The main upper level trough is well to the north across the Great Lakes but 0-6 bulk shear values are around 20-30 kts. Seeing a minor increase in PW values ahead of the boundary with some low-level convergence. PW values range from around 1.4-1.6 inches, which is around the 50th-75th percentile for early June. Forecast thinking has not really changed from previous, expect there will be a few strong to marginally severe storms this afternoon through about 6pm. Damaging winds, hail up to quarter size, and localized flash flooding from heavy rainfall will be the main impacts. Models all indicate that the front will move through rather quickly this afternoon and evening with dry air moving in overnight. Dewpoints are currently in the upper 50s to low 60s across W TN. Temperatures will be noticeably cooler tonight with lows in the mid 50s to low 60s. The drier air and winds around 5-10 mph should prevent any widespread fog formation tonight. A beautiful day is forecast on Monday with dewpoints in the 50s highs in the upper 70s and low 80s with no rain chances. .LONG TERM...(Monday night through Saturday)... Dry northwesterly flow will continue over the Southern Appalachian Region Monday night into Tuesday for continued dry conditions and normal to slightly below normal seasonal temperatures. Tuesday night...a broad...weakening boundary will settle south and into our northern areas. There may be enough moisture and lift associated with the boundary to generate a few isolated showers...possibly with a stray rumble of thunder. By Wendesday...the boundary should weaken just enough to minimize the chance of convection but should still generate a few bands of clouds...so expect a mainly dry day. Model and run consistency becomes rather poor through the rest of the extended and confidence is low. The current tend is towards a dry Thursday. Friday is shaping up to be a transition day with the next system moving into the region for the weekend. && .PRELIMINARY POINT TEMPS/POPS...
