Areas affected...Portions of western Tennessee/vicintiy

Concerning...Severe potential...Watch unlikely 

Valid 010004Z - 010200Z

Probability of Watch Issuance...20 percent

SUMMARY...Storm intensification/development is possible across
portions of western Tennessee/vicinity in the next two hours. A
brief tornado is possible.

DISCUSSION...Storms are developing/intensifying ahead of the cold
front within the warm sector across portions of northern
Mississippi/western Tennessee. Low-level shear and SRH will locally
increase as surface winds back to the southeast across the area per
recent observations. Better hodograph curvature and storm motion
demonstrate potential for brief/weak tornado development with the
strongest storm(s). Buoyancy is marginal in the area (MLCAPE of
300-600 J/kg), but there is sufficient shear (effective bulk shear
of 40-50 knots) for strong/severe storm development. Storms may
become elevated as the boundary-layer cools, which would decrease
tornado potential. Given the current observations/recent trends, a
watch is unlikely in the near term.
