Areas affected...western Tennessee

Concerning...Tornado Watch 97...

Valid 010252Z - 010445Z

The severe weather threat for Tornado Watch 97 continues.

SUMMARY...Severe threat continues. Potential for large hail and a
few tornadoes.

DISCUSSION...A line of storms across western Tennessee has shown
better organization in the last hour. Embedded supercell structures
have been observed on radar. Storms are advancing eastward into an
increasingly favorable low-level shear. The VAD profile at KNQA has
becoming elongated and linear in the lower 1 km while still
maintaining some curvature. Further east, low level shear profiles
remain large with curvature in the low levels. The VAD profile at
KOHX (Nashville, TN) is observing 0-1km shear around 700 m2/s2,
though instability does wane with eastward extent into Middle
Tennessee. Large hail will be the main threat with the line across
western Tennessee, with increasing risk for tornadoes as it
continues to track eastward. The tornado risk will continue with any
discrete cells (such as those near Memphis west of Waynesboro
Tennessee.)
