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

   Concerning...Severe potential...Watch unlikely 

   Valid 181644Z - 181845Z

   Probability of Watch Issuance...20 percent

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

   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.
