The local office's own words before this special weather statement 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 special weather statement went out at Aug 4, 2:40 PM CDT, 2 hours 30 minutes earlier.
Area forecast discussion, Aug 4, 2:40 PM CDT, 2 hours 30 minutes before
Area Forecast Discussion National Weather Service Nashville TN 240 PM CDT Sun Aug 4 2019 .DISCUSSION... The advertised showers and thunderstorms are finally filling in as of 19Z...about an hour or so after originally expected. Still expect storms area wide this afternoon and evening. Coverage should be confined to south of I-40 and east of I-65 after midnight. With the slow nature of these storms heavy rainfall and some isolated flooding is still a threat. There could also be some strong gusty winds as the storms collapse and outflow boundaries move through. The upper level shortwave that is responsible for the increased storms this afternoon and evening will move through tonight. Have left a low end chance for storms during the afternoon for southeast Middle TN tomorrow. With light wind and a moist ground expect patchy ground fog in the morning. It looks like this upper level shortwave should move past the area by Tuesday leaving us dry for the most part. Did include some slight chance afternoon showers. Northwest flow will dominate the forecast from Wednesday through the weekend. This will allow for a couple of additional shortwaves for the end of next week. If the long range models can agree on a solution it is possible that around Sunday will be dry. Temperatures will continue to be around normal for August. && .AVIATION... 18Z TAF DISCUSSION. Widespread showers and storms are expected this afternoon and into the early evening hours. All terminals should see vicinity storms throughout this time frame with occasional storms directly impacting terminals. Some storms could have strong winds as they collapse and decreased visibility due to heavy rainfall. Storms should diminish by 03z and leave calm conditions with clearing skies, which will encourage fog development and reduced visibilities at all terminals through the early morning hours on Monday. && .PRELIMINARY POINT TEMPS/POPS... Nashville 68 91 69 91 71 / 30 10 10 20 40 Clarksville 66 89 67 89 70 / 10 10 10 20 30 Crossville 63 84 63 85 67 / 60 20 10 20 30 Columbia 66 89 67 90 70 / 30 20 10 20 30 Lawrenceburg 66 88 67 89 70 / 50 20 10 20 30 Waverly 67 89 67 90 70 / 20 10 10 20 40 && .OHX WATCHES/WARNINGS/ADVISORIES...
