   Areas affected...south-central Mississippi into southwest Alabama

   Concerning...Tornado Watch 106...107...110...

   Valid 122154Z - 122300Z

   The severe weather threat for Tornado Watch 106, 107, 110 continues.

   SUMMARY...Two tornadic supercells are likely to track northeast
   across south-central and southeast Mississippi in the next couple of
   hours. Significant, long-track tornadoes are likely.

   DISCUSSION...A tornadic supercell currently moving over northwest
   Jones County Mississippi has exhibited extremely strong rotation
   with rotational velocity values around 100 knots on multiple scans.
   Additionally, multiple scans of TDS have been observed over the last
   hour. Given the very favorable storm/tornado environment,
   characterized by STP of 7+, MLCAPE of 2000+ J/kg, and 0-1 km SRH of
   400+ m2/s2, this tornadic supercell is likely to continue tracking
   northeastward for at least the next hour and likely longer. 

   Back to the southwest, another tornadic supercell is moving over
   southern Jefferson Davis County that has exhibited strong rotation
   with rotational velocity values of 60+ knots. This is following a
   very similar track to the previous tornadic supercell with the
   potential for communities to be affected twice in a relatively short
   amount of time. With no other convection degrading the warm sector
   south and downstream of these storms, they are likely to continue
   across Mississippi and into west/southwest Alabama.
