   Areas affected...southeastern Missouri...southern Illinois...and
   western Kentucky

   Concerning...Tornado Watch 212...

   Valid 090334Z - 090500Z

   The severe weather threat for Tornado Watch 212 continues.

   SUMMARY...Risk for damaging winds and hail, and a couple of
   tornadoes, continues across the discussion area (within Tornado
   Watch 212).

   DISCUSSION...A bowing band of storms is moving out of southeastern
   Missouri into southern Illinois at this time, while more
   isolated/rotating cells continue to gradually increase in coverage
   from the Missouri Bootheel into western Kentucky.  With this area on
   the northern fringe of a moderately unstable airmass, storms will
   likely maintain intensity over the next couple of hours.  Aided by
   veering low-level flow that increase to 50-plus kt above 4km AGL,
   shear will support updraft rotation.  Resulting, all-hazards severe
   risk will therefore likely continue through midnight, spreading
   gradually eastward with time, toward eastern portions of the watch.
