Areas affected...Portions of Eastern Tennessee and Northwest Georgia

Concerning...Severe potential...Watch possible 

Valid 141900Z - 142100Z

Probability of Watch Issuance...60 percent

SUMMARY...Storms have begun to initiate along a confluence zone in
eastern Tennessee. Further development southward into northwest
Georgia is possible. Strong wind fields will support organized
storms capable of all severe hazards. A tornado watch is possible
within the next hour.

DISCUSSION...In the wake of early morning convection, modest
boundary layer recovery has occurred across eastern Tennessee. An
area of agitated cumulus has developed along a confluence zone just
east of Crossville, TN. Surface observations from the last hour have
indicated that boundary layer moisture has mixed out to a degree.
Nonetheless, dewpoints in the upper-50s to low 60s have contributed
to MLCAPE values around 1000 J/kg. As storms are now beginning to
develop on the north end of the confluence band, the expectation is
for continued development southward, as supported by some CAMs.
Given the strong wind fields -- effective bulk shear of 60-75 kts
per objective mesoanalysis -- organized convection capable of all
hazards is expected. A tornado watch is possible within the next
hour.
