Areas affected...Middle/Eastern TN

Concerning...Severe Thunderstorm Watch 388...

Valid 260554Z - 260730Z

The severe weather threat for Severe Thunderstorm Watch 388
continues.

SUMMARY...Local extension of Severe Thunderstorm Watch 388 as the
threat for damaging gusts expands into more of eastern TN.

DISCUSSION...An organized convective line continues to push
southeastward across northern middle and eastern TN, with recent
storm motion estimated at 37 kt. Strong to severe gusts have been
reported within this line over the past hour, including a 51 kt gust
at EKQ. The downstream air mass is characterized by ample low-level
moisture, steep mid-level lapse rates, and 40 to 50 kt of 0-6 km
bulk shear. Bulk shear vector is also north-northwesterly, which is
orientated favorably for downstream propagation of the east-west
line. This factors suggest some severe potential will continue with
this line for at least the next hour or two. Current storm motion
takes the ongoing line to the edge of the watch around 0630Z, and
local extension may be warranted to cover the anticipated severe
threat into more of eastern TN.
