   Areas affected...southeast Mississippi into central Alabama

   Concerning...Tornado Watch 45...46...

   Valid 152029Z - 152230Z

   The severe weather threat for Tornado Watch 45, 46 continues.

   SUMMARY...Multiple supercells capable of intense to potentially
   violent tornadoes to persist into the evening.

   DISCUSSION...A line of supercells continues from east-central
   Alabama to south-central Mississippi. Most of these supercells have
   a history of tornadoes including a few intense to potentially
   violent tornadoes. The environment ahead of these supercells remains
   very favorable for tornadoes with 1500 to 2000 J/kg MLCAPE per SPC
   mesoanalysis and 0-1km SRH in excess of 300 m2/s2 per GWX VWP. This
   yields a STP value around 5 which is forecast to shift east with
   these storms through the evening. Convective trends have shown rapid
   strong to intense tornado development in supercells with unimpeded
   inflow and circulation disruption when surrounding
   showers/thunderstorms impede this inflow. Expect this pattern to
   continue into the early evening with the greatest concern being
   supercells with clear inflow of at least mid 60s dewpoints. 

   The threat for intense to potentially violent tornadoes will persist
   from these supercells as long as they can remain ahead of the
   developing line of storms across central Mississippi. Based on
   current storm motions, they should remain ahead of this line of
   storms into the early evening.
