What forecasters said that day
The local office's own words before this severe thunderstorm warning went out, 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 this severe thunderstorm warning went out at Jun 28, 11:58 AM CDT, 1 hour 11 minutes earlier.
Area forecast discussion, Jun 28, 11:58 AM CDT, 1 hour 11 minutes before
Area Forecast Discussion National Weather Service Nashville TN 1158 AM CDT Thu Jun 28 2018 .DISCUSSION... A Severe Thunderstorm Watch remains in effect for much of western and southern Middle Tennessee through 700 pm this evening. Even though convection, along and east of I-65, has shown a sustained progression to the south, a new wave of thunderstorms, pushing into our northwestern counties, from Kentucky, could spread additional thunderstorms and heavy rainfall back across northern parts of the severe thunderstorm watch area later this afternoon. As a result, because of this second shot of potential heavy rainfall, will probably issue a short-fused FFA to coincide precisely with the Severe Thunderstorm Watch area, and let it also run through 7 pm. KOHX shows that 1 to 2 inches of rain has been common along the band of storms over the past 3 hrs, and an additional 1 to 2 inches is likely over some of those same areas this afternoon. && .AVIATION... 12Z TAF DISCUSSION. One more active day expected today as a weak boundary passes. Convection already occurring CSV vcnty expected to spread west in the mid/late morning. Storms could affect all sites by 18z. CIGs/VSBYs behind the precip will improve rapidly but MVFR/IFR level fog likely to develop late night. && .PRELIMINARY POINT TEMPS/POPS...
