Deaths and injuries are direct and indirect together, as the offices filed them. Damage is property and crops in the dollars of the year, not adjusted for inflation, and only where an office estimated it.
A shortwave trough pushing a weak cold front through the area served as the forcing for this event. The only severe weather observed was a brief EF-0 tornado accompanied by severe rear-flank downdraft winds that injured several residents. This event was unusual: while effective shear was strong at 40 to 50 knots, CAPE was very limited at less than 500J total, and lapse rates were really weak below 6C from the surface upwards. The parent thunderstorm was only broadly and very weakly rotating at time of tornadogenesis.

...New AVIATION...
.SHORT TERM...
(Tonight through Saturday)
Issued at 1225 AM EDT Fri May 30 2025
Key Messages:
1. Showers and thunderstorms expected overnight and into the
daytime hours today.
2. Decrease in storms and cloud coverage behind the front in the
afternoon/evening.
Discussion:
Currently a few isolated showers are moving through the eastern
Tennessee Valley during the overnight ours. These storms are being
aided by an incoming shortwave and front moving into the region.
Expect the front that is currently closer to the Mississippi river
to move towards the southern Appalachians for much of the night.
Shortly after sunrise we should see the front moving near the
southern Appalachians and this will also be the time frame when we
should experience the greatest coverage of showers and
thunderstorms. There will be enough instability that we could see
a few stray strong thunderstorms capable of producing strong wind
gusts and small hail. However the threat for widespread severe
weather appears low on the western side of the Appalachians
Mountains today.
As we move into the evening hours on the back side of the front we
should see a dramatic decrease in shower and storm coverage, but
cannot completely rule out a few rogue showers associated with
the wrap around moisture and instability as the trough/low moves
up into the the New England Region.

.LONG TERM...
(Saturday night through next Friday)
Issued at 1225 AM EDT Fri May 30 2025
Key Messages:
1. Scattered afternoon and early evening showers Saturday and
Sunday.
2. Drier and warmer conditions return for early next week.
Discussion:
An upper trough will remain across eastern United States with
cyclonic flow over the southern Appalachians. Probabilistic
models retain area of greatest instability over the northern half
of the area Saturday and southern half Sunday. The cyclonic flow
and cool air aloft will produce scattered mainly afternoon and
early evening convection. Thunderstorms, some strong, are possible
with the main concern hail up to one-half inch and strong and
gusty winds. For early next week, upper trough moves slowly east
allowing for upper and surface ridging to build into the area.
Drier airmass and eventually rising heights will allow for warmer
temperatures.

.AVIATION...
(12Z TAFS)
Issued at 725 AM EDT Fri May 30 2025
A surface trough will move across the TAF sites this morning
associated with upper jet forcing to produce widespread showers
and possibly a thunderstorm. Besides the convection, plenty of
surface/boundary layer moisture is producing areas of low clouds
and fog.
The surface trough will move across CHA/TYS around 14-15Z and TRI
16-17Z with winds becoming more westerly. The tightening pressure
gradient and better mixing of boundary layer jet will increase
winds by mid to late-morning. Gusts of 25-28 knots are possible in
the afternoon.
Wrap-around moisture into TRI/TYS will redevelop scattered showers
over TYS/TRI by late afternoon.

An EF0 tornado touched down in southern Loudon County in the early morning hours with max winds of 85 mph. Tornado was in Loudon County for roughly 1 mile before exiting into northern Monroe County east of Holt Road. Several injuries occurred when either the tornado itself or the rear flank downdraft winds rolled a camper RV several times up and over a wooden service post. In addition to the RV on the south side of the damage swath, several trees suffered damage, there was roof damage to small structures and a barn, and the tornado left cycloidal markings in the field beyond the RV and houses. When the tornado reached the tree line at the edge of Loudon, several trees had large branches broken off.
