   Areas affected...east-central MO and far western IL

   Concerning...Tornado Watch 207...

   Valid 212312Z - 212345Z

   The severe weather threat for Tornado Watch 207 continues.

   SUMMARY...Potential significant tornado entering western portions of
   the St. Louis Metro area.

   DISCUSSION...A linear segment has interacted favorably with a
   warm-frontal zone located west-to-east through parts of the St.
   Louis Metro area.  This storm is moving northeast around 50 knots,
   and experimental guidance suggests continued potential for a
   significant tornado in the region.  This storm should continue
   migrating northeastward through the western and northern portions of
   St. Louis Metro area over the next hour or so.
