Areas affected...Portions of eastern Tennessee...Kentucky...and far
western Virginia

Concerning...Severe Thunderstorm Watch 4...

Valid 070228Z - 070330Z

The severe weather threat for Severe Thunderstorm Watch 4 continues.

SUMMARY...Scattered severe thunderstorms will continue to progress
eastward across portions of eastern TN over the next hour. Hail up
to the size of golf balls, damaging wind gusts exceeding 60 mph, and
a tornado or two remain possible.

DISCUSSION...Latest radar imagery shows two dominant supercells
moving ESE near Rutledge and Knoxville, TN. These right moving
storms have exhibited rotation in the lowest levels over the past
30-60 minutes, and are located within a buoyancy axis extending
southwest to northeast. This is also where stronger southwest flow
just above the surface (40-50 kt) continues to be observed via the
MRX VWP, yielding 0-1 km SRH of 300-350 m2/s2. This area of both
enhanced instability and low level shear should continue to favor
supercells for at least another hour, with a threat of damaging
winds, hail, and perhaps a tornado.
