Areas affected...portions of middle Tennessee

Concerning...Tornado Watch 107...

Valid 032307Z - 040000Z

The severe weather threat for Tornado Watch 107 continues.

SUMMARY...Enhanced tornado potential over the next 1-2 hours across
portions of middle Tennessee.

DISCUSSION...A pair of supercells is ongoing across portions of
middle Tennessee, and both of these cells are along a synoptic
stationary boundary draped generally east-northeast to
west-southwest across the area. These storms are likely
surface-based with air ahead of the boundary sufficiently unstable
(1000 J/kg MLCAPE per mesoanalysis) and with strong low-level shear
(20 kts of 0-1 km shear per regional VWPs). Additionally, the
southern of these storms has a history of producing tornadoes and
significant (2"+) hail. Thus, these storms have enhanced tornado
potential over the next 1-2 hours. Surface moisture decreases to the
east, and this may limit the eastward extent of the tornado risk
with these storms.
