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 May 6, 6:23 PM CDT, 35 minutes earlier.
Area forecast discussion, May 6, 6:23 PM CDT, 35 minutes before
Area Forecast Discussion National Weather Service Nashville TN 623 PM CDT Thu May 6 2021 .UPDATE... FOR 00Z AVIATION DISCUSSION. && .DISCUSSION... Convection beginning to take place upstream across the Mo bootheel northeastward along the Ohio River. Latest Hrrr data has the activity reaching our far northwestern corner around 3-4 pm. A svr tstm watch is now in effect to our west. Severe wx parameters do indeed look better across that area and not as favorable here. Therefore, it looks as though the severe weather potential in our western areas will largely be momentum dependent. That said, recent storm history upstream will be key. So far, no reports of wind or hail but a few warnings have been issued across the bootheel. For our area, wind and hail are the primary threats for primarily those areas west of i-65. The weakening convection will end across our Plateau by 10pm - midnight. Moving on, Friday is looking partly cloudy and nice with highs 65 to 70. Conditions will begin to change on Saturday as a warm front begins to work northward. Low shower chances will return early Saturday and continue into Saturday night. On Sunday, the warm front will be north of the mid state and destabilization will be on the increase. A cold frontal passage is expected Sunday evening. Prior to this, frontal and pre frontal forcing will attempt to tap into the instability and increasing shear. Another round of severe storms will be possible. Note however that at this time we are not outlooked. That will likely change to at least a marginal as we approach Sunday. For our near term temps, below normal values are expected. However, we will be close to the normal, upper 70s highs, on Sunday, in advance of that boundary. In the ext fcst, after the fropa on Sunday evening, temperatures will cool down to 7-10 degrees below normal for the entire week. The subtropical jet will become active and send an inverted sfc trough our way by Wednesday. So the week as a whole will be on the unsettled side with low shower chances, except somewhat higher chances for Wednesday. Qpf amounts are not looking too bad. Looks like 1 to 1 1/2 inches over the next 7 days. && .AVIATION... 00Z TAF DISCUSSION. Line of showers and a few thunderstorms are working their way through the area, currently impacting KBNA/KMQY with near MVFR cigs and IFR/MVFR vis. Strong northwest winds around 20 to 30 knots will be possible for another half hour to around 00Z, then expect 5 to 10 knot winds out of the west/northwest overnight. Showers should impact KCSV from around 01Z through 03Z. Rest of the overnight will be VFR for all terminals except for KCSV which may see MVFR cigs from 06Z through sunrise. VFR conditions area wide during the day Friday with northwesterly winds around 10 knots. && .OHX WATCHES/WARNINGS/ADVISORIES... NONE. && DISCUSSION......21 AVIATION........Barnwell
