Areas affected...northern middle Tennessee into southeast Kentucky

Concerning...Tornado Watch 36...

Valid 030702Z - 030900Z

The severe weather threat for Tornado Watch 36 continues.

SUMMARY...A tornado threat may persist for a few more counties east
and northeast of the Nashville area. Damaging wind gusts are also
possible, possibly extending into southern Kentucky.

DISCUSSION...A long-lived supercell, now with a confirmed,
potentially intense tornado, continues to move east across the
Nashville area. This southern-most supercell is on the southern
fringe of the larger-scale area of ascent, and firmly within the
local effective SRH maximum where values over 500 m2/s2 exist.

Surface observations indicate a plume of mid 50s F dewpoints extends
east/northeast of this storm, and while instability weakens with
eastern extent, strong shear may allow these storms to persist for
at least an hour.
