TDWhat 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 Morristown, TN wrote its last area forecast discussion before this severe thunderstorm warning went out at Aug 16, 2:43 PM EDT, 3 hours 20 minutes earlier.
Area forecast discussion, Aug 16, 2:43 PM EDT, 3 hours 20 minutes before
Area Forecast Discussion National Weather Service Morristown TN 243 PM EDT TUE AUG 16 2016 .SHORT TERM (Today and tomorrow)... Showers and thunderstorms have developed in the West Tennessee Valley, and east of the Southern Appalachian Mountains. Expect storms to continue through the afternoon and into the evening. There is a bit more CAPE to work with today, but the current trend is to have less coverage than we saw yesterday. Similar to yesterday also, we could see a few strong to marginally severe storms in the area, but again, widespread severe weather is not expected today. Also, we could see some patchy fog overnight, particularly where showers occur today. Tomorrow we will have a bit more moisture over us as the front fizzles out and moisture flakes off south and closer to our region. This will likely bring an increase in cloud coverage leading to cooler temperatures across the area. In addition another round of widespread showers and thunderstorms will again be possible tomorrow. .LONG TERM...(Wednesday night through Tuesday)...Models continue to be in decent agreement for the most part...and run to run consistency is fair. Forecast confidence is about average for this time of year. Models still depict the remnants of a dissipating frontal boundary sagging into the area in the Wed night/Thursday time frame...then a stronger cold front pushing through sometime Sunday night or Monday. With considerable moisture lingering through the weekend...expect to see at least scattered convection each day. By Tuesday drier air is forecast to be over the area behind the cold front...so should be less humid and precip free. && .PRELIMINARY POINT TEMPS/POPS... Chattanooga Airport, TN 73 88 71 88 / 30 60 40 40 Knoxville McGhee Tyson Airport, TN 72 87 69 85 / 30 60 40 50 Oak Ridge, TN 72 86 70 85 / 30 60 40 50 Tri Cities Airport, TN 69 87 69 82 / 30 60 40 50 && .MRX WATCHES/WARNINGS/ADVISORIES...
