   Concerning...Tornado Watch 320...323...324...

   Valid 270121Z - 270245Z

   The severe weather threat for Tornado Watch 320, 323, 324 continues.

   SUMMARY...Threat for significant-severe gusts is increasing within
   the ongoing convective line from southeast Illinois and southern
   Indiana into western Kentucky and far southeast Missouri/Missouri
   Bootheel.

   DISCUSSION...Well-organized convective line continues to push
   quickly southeastward across southern IL and southeast MO/MO
   Bootheel. Recent storm motion with this line was estimated around 50
   kt, which would bring the line into central KY and southern IN
   between 0230 and 0300Z. Several severe gusts have been noted within
   the line, including recently at KSLO at 56 kt. 

   This northeast-to-southwest orientated line is about to intersect a
   west-to-east line of supercells across far southern IL into far
   southwest KY. This interaction is expected to result in
   intensification of the line, with some potential for this area to to
   surge eastward, becoming the apex of the bow. Significant-severe
   gusts (i.e. 75-90 mph) are likely within this vicinity over the next
   few hours. Northern portion of the bow remains well-organized, with
   some interaction with the newly strengthening warm-air advection
   cells across southern IN. Significant-severe gusts appear possible
   here as well.

   An embedded supercell persists at the southern end of the line, with
   another supercell in its wake to the west over Carter County MO.
   Both of these cells will continue to pose a risk for all severe
   hazards for the next hour or two.
