   Areas affected...Southern IL...Southeast MO

   Concerning...Tornado Watch 320...

   Valid 270001Z - 270130Z

   The severe weather threat for Tornado Watch 320 continues.

   SUMMARY...Well-organized convective line continues to surge
   southeastward from southern Illinois into southern Missouri. A
   corridor of significant wind gusts (i.e. 75+ mph) appears probable
   across south-central into southeast Illinois.

   DISCUSSION...Ongoing convective line has shown an increase in
   forward propagation over the last hour or so, particularly with the
   portion of the line that moved through the LSX area. Velocity data
   from KLSX continues to show strong outbound velocities within the
   portion of the line moving through west-central IL. Significant
   severe gusts (i.e. greater than 75 mph) are possible within this
   portion of the line as it moves through more of southern IL.

   Southern portion of the line has allow surged forward, though not
   with quite the same speed as farther north. However, the
   southernmost cell within the line now has a more outflow-dominant
   signature, and cell interactions with the ongoing supercells across
   south-central MO are probable. Strong gusts are expected to become
   more prominent within this portion of the line once these
   interactions are complete.
