Areas affected...portions of northeast TN into extreme southeast KY

Concerning...Severe Thunderstorm Watch 265...268...

Valid 112248Z - 112345Z

The severe weather threat for Severe Thunderstorm Watch 265, 268
continues.

SUMMARY...A narrow corridor of tornado potential may persist another
1-2 hours across parts of northeast Tennessee into extreme southeast
Kentucky.

DISCUSSION...Tornado potential is expected to continue the next 1-2
hours across parts of northeast TN into extreme southeast KY. STP
values near 1 coinciding with 0-1 km SRH of 150 m2/s2 are evident in
objective analysis data. Meanwhile, VWP data from MRX indicated an
enlarged low-level hodograph supporting low-level rotation an
environment with surface dewpoints in the mid 60s F and MLCAPE
values of 1000-1500 J/kg. As a result, discrete supercells with an
attendant risk for a tornado or two may persist for another 1-2
hours.
