   Areas affected...Northeast and east central Mississippi

   Concerning...Tornado Watch 36...38...

   Valid 150549Z - 150715Z

   The severe weather threat for Tornado Watch 36, 38 continues.

   SUMMARY...Potential for strong-intense (EF2-EF3+) tornadoes will
   persist with a supercell cluster moving into northeast Mississippi,
   while new supercell development is possible into east central
   Mississippi.

   DISCUSSION...An intense supercell is approaching the southern tier
   of counties in PDS tornado watch #36 across northeast MS.  This
   storm is located in the open warm sector in a zone of low-level
   moisture advection and strong low-level shear with large, curved
   hodographs per regional VWP time series.  The potential for
   strong-intense tornadoes will persist with this cluster for the next
   1-2 hours.  Farther south, thunderstorms are developing in the warm
   advection zone along the east edge of the richer moisture into east
   central MS.  One or two supercells could emerge from this developing
   convection and pose a tornado threat in the next few hours.  For
   this reason, a local eastward extension of tornado watch #38 will
   need to be considered by 06-07z.
