ShamburgerWhat 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 Jul 21, 12:09 AM CDT, 18 minutes earlier.
Area forecast discussion, Jul 21, 12:09 AM CDT, 18 minutes before
Area Forecast Discussion National Weather Service Nashville TN 1209 AM CDT Sat Jul 21 2018 .UPDATE... FOR 06Z AVIATION DISCUSSION. && .DISCUSSION... Per current radar trends and consensus of short term models, will curtail any potential of rounds of shwrs/tstms to generally the Upper Cumberland Region overnight. Most of the rest of the mid state will have a chance of showers and thunderstorms thru the early morning hours. Although not a lot of upstream convection noted, especially to our northwest presently, it is still just so unstable with copious moisture, that if a weak upper level disturbance can provide at least some marginal lift as it approaches and moves across the mid state region, sct shwrs and tstms could still develop to our northwest and move thru the mid state region overnight. So, even though there is little if any activity at this point upstream and skies across a good portion of the mid state are fair to clear presently, will continue to mention the possibility of a chance of showers and thunderstorms across most of the mid state region. Tweaked hrly temp, dewpoint, and wind speed/direction grids. Adjusted toward sunrise the morning hours the coverage of shwrs/tstms decreasing their coverage as sunrise approaches. Current temperature trends without the expected rainfall this evening are much warmer than previously expected, and thus will raise overnight lows by several degrees. As of this time, remainder of forecast continues to be on track. Will thus be updating the suite of forecast products shortly. && .AVIATION... 06Z TAF DISCUSSION. CKV/BNA/MQY/CSV...It looks like CSV will have the best chance of experiencing a round of shwrs/tstms, and will break out a tempo group to address this possibility. Will mention MVFR ceilings and IFR vsbys with this TEMPO group. Otherwise, even with clr skies and not much of activity noted to our northwest, still can not rule out at least in the vcnty shwrs/tstms at the other terminals at least thru 21/10Z. It still appears that another round of shwrs/tstms could develop 21/18Z-22/02Z. However, uncertainty still exist for actual location development at terminals, but can not rule out in vcnty, and thus mentioned. && .OHX WATCHES/WARNINGS/ADVISORIES... NONE. && DISCUSSION......31 AVIATION........31
