...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS FOR PORTIONS OF
THE TENNESSEE VALLEY INTO THE SOUTHERN AND CENTRAL APPALACHIANS...

...SUMMARY...
Isolated severe gusts may accompany the stronger storms over parts
of the southern and central Appalachians on Monday.

...Synopsis...
Mainly zonal mid-level flow, with embedded impulses, will
characterize the upper air pattern east of the Rockies, with a
mid-level trough slowly progressing across the Southwest on Monday.
Eastern portions of a diffuse cold front will linger over portions
of the eastern TN Valley into the central Appalachians Monday
afternoon, supporting scattered thunderstorm development. Given
upper 60s F dewpoints contributing to 1500+ J/kg of tall and thin
MLCAPE, a few wet downbursts capable of producing damaging gusts may
occur with the stronger storms.
