   Areas affected...Portions of South Carolina and Tennessee Valley

   Concerning...Severe potential...Watch possible 

   Valid 062153Z - 062330Z

   Probability of Watch Issuance...40 percent

   SUMMARY...Large hail and damaging winds are possible with modestly
   organized, pulse-severe storms in parts of the Tennessee Valley into
   South Carolina. Brief tornadoes are also possible for the next 1-2
   hours in Middle/Eastern Tennessee with more discrete storms near the
   MCV.

   DISCUSSION...Large hail (with one 2 in. report) has occurred in
   Middle Tennessee this afternoon. At least two TDS were also evident
   on local radars. As this MCV continues east, strong to severe storms
   are possible for the next 1-3 hours. Should cold pool organization
   occur, some of this activity could reach parts of South Carolina
   this evening.

   Heating of a moist airmass along with some modest influence from an
   MCV in the Tennessee Valley has promoted the development of widely
   scattered storms across parts of South Carolina and nearby vicinity.
   Deep layer shear is quite modest and outflow from storm has become
   apparent on local radars. Some cold pool organization has occurred
   in Upstate South Carolina which would locally enhanced the potential
   for wind damage. Large hail has also been observed early in the
   storm life cycle.
