Areas affected...Northeast MS into northern AL and southern middle
TN

Concerning...Severe potential...Watch unlikely=20

Valid 181644Z - 181845Z

Probability of Watch Issuance...20 percent

SUMMARY...Isolated hail and damaging gusts may accompany storms this
afternoon.

DISCUSSION...Convection associated with a compact midlevel low
(which is centered near the TN/AR/MS border) is gradually
intensifying late this morning from northeast MS into northern AL
and southern middle TN. Some continued increase in storm coverage
and intensity may continue into this afternoon, within a moist and
uncapped environment (with MLCAPE increasing to near/above 1000
J/kg). This region is on the northern periphery of stronger flow
aloft, but effective shear of 25-35 kt could occasionally support
some modestly organized storm structures through the afternoon.
Isolated hail could accompany any storms that remain semi-discrete,
while a bowing segment or two could evolve with a threat of isolated
damaging gusts as storms spread eastward across northern AL and
southern middle TN.
