What happened

The episode as NWS OHX wrote it up.

A late Spring storm system brought several waves of strong to severe thunderstorms to Middle Tennessee during the afternoon and evening hours on May 27. One supercell thunderstorm developed during the afternoon across Wilson County, then moved east-southeast across Smith, Putnam, White, and Cumberland Counties, producing very photogenic and at times rotating wall clouds along with several reports of hail. Later in the day, two lines of severe thunderstorms called Mesoscale Convective Systems (MCS) moved southeast out of western Kentucky across the region, producing widespread wind damage and several reports of large hail. The worst damage occurred across Putnam, Jackson, Overton, Fentress, White, and Cumberland Counties, where straight-line winds up to 95 mph caused major wind damage. In fact, the Putnam County Emergency Manager and Cookeville Mayor both stated this was likely the worst severe thunderstorm damage ever in that area. The second line of severe thunderstorms caused less severe but still widespread wind damage across Humphreys, Hickman, Maury, and Perry Counties. The Storm Prediction Center in Norman, Oklahoma stated that each of these two damaging lines of thunderstorms meet their newly updated definition of derecho, or long lived, widespread damaging wind storms that travel hundreds of miles. Due to the widespread wind damage, a Presidential Disaster Declaration was made for Putnam, Cumberland, and Smith Counties in June 2017.

.DISCUSSION...

Surface high is centered just off the Florida Gulf Coast this hour
as a warm front becomes established along the Ohio Valley. This
leaves Middle Tennessee in a warm, moist & unstable environment
that is primed for thunderstorms today & tomorrow. Earlier
activity has completely dissipated, but a second round of storms
is now developing north of the TN/KY line, with weaker cells
popping up across Middle Tennessee. Skies have partially cleared
after the earlier storms, so this is allowing temperatures to warm
considerably and should help destabilization.

The morning sounding from OHX shows a strong capping inversion
situated around 750 mb, with steep mid-level lapse rates and
surface-based lifted index of -3. MUCAPE was just shy of 2,000
J/kg. GFS forecast soundings do show some erosion of the cap by
18Z tomorrow with the mid-level lapse rates contributing to higher
CAPE's and impressive LI values. Forecast SRH's indicate very
weak shear, so straight-line winds and large hail appear to be the
primary threats with the anticipated severe weather tonight and
tomorrow.

It appears as though isolated/scattered storms will persist
throughout the day and early evening until more organized
convection enters the mid state maybe 02Z or later. There is some
discrepancy between the NAM and GFS regarding timing of later
(tomorrow) storms, so on Sunday we'll just stick with likely
POP's most areas to go along with SPC's slight risk for day 2.

We likely won't see fropa here in Middle Tennessee until after
12Z Monday, so we won't see POP's drop off until then. Look for
slightly cooler temperatures (near normal or slightly above) to
start off next week and lasting at least until next weekend. A wet
pattern will slip back in rather quickly, with isolated or
scattered POP's most areas from Tuesday through the end of the
forecast period.

likely to go below 3kft overnight.

36.212, -85.609

A NWS storm survey found a severe 15 mile long by 1 to 2 mile wide downburst caused major damage across Cookeville and surrounding areas of central Putnam County. Damage was first reported east of Bloomington Springs where trees and power lines were blown down. Scattered tree and power line damage contined to the southeast to near the Nashville Highway, including a tree falling and blocking Peach Orchard Road at Flatt Road, and a tree blown down onto a vehicle with the occupant trapped inside at County Farm Road and Gainesboro Grade. More significant and widespread damage occurred across the center of Cookeville, where the roof was blown off a business on Oak Avenue and the canopy was blown off another business on Whitney Street. Dozens of very large trees were also snapped and uprooted with several falling on homes and vehicles and the majority of roads in the city blocked. One tree fell through and destroyed much of a home on Briargate Way. Another tree fell onto a moving vehicle on East Spring Street crushing the car and narrowly missing the driver. Numerous power lines were also blown down with power poles snapped and power knocked out to up to 60 percent of the city of Cookeville and surrounding Putnam County. Farther to the east, numerous trees and power lines continued to be blown down on Mountain Top Lane on Buck Mountain with the roadway blocked, as well as in the Poplar Grove area and around City Lake. Wind speeds were estimated to range from 75 mph up to 95 mph. In June 2017, a Presidential Disaster Declaration was made for Putnam County due to the widespread wind damage.
