What happened

The episode as NWS MRX wrote it up.

A long lived bowing line of convection moved into the Southern Appalachian region late in the evening and made rapid progress across the region into the early morning hours of the next day. The strong winds associated with the line of storms produced widespread wind damage. While damage was reported in a few spots across Northeast Tennessee, most of the event impacted Central East and Southeast Tennessee and Southwest North Carolina.

What forecasters said that day

The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

.DISCUSSION...
Large bowing MCS continues to work east across Middle TN and
southcentral/southeast KY this evening. Out ahead, a warm front
and consequent swly moisture advection continue to move into the
TN Valley at this time. Thus, am expecting continued elevated CAPE
levels regionwide, with the most unstable regions along/west of
the I75 corridor tonight. The primary threat tonight will be
damaging winds along/ahead of the passing MCS, some gusts as high
as 60-70mph are expected. Also, backed flow out ahead of the
front could enhance localized llv helicity, therefore a few
embedded tornadoes cannot be ruled out. All said, looking at a
stormy night across east TN and southwest VA/NC with timing as
follows. Latest HRRR runs favor intrusion of the bowing line
across the Plateau by 11PM, then moving east/southeast approaching
the I75 corridor by around midnight, before moving further east
across the I81 corridor into the foothills/mountains closer to the
2AM timeframe. Severe Thunderstorm Watch 419 continues through
2AM.

As for the fcst, tweaked pops to align with current coverage
westward, as well as latest CAMPOP trends over the next 3-4 hours.
No other sig changes needed/made with this update.
