   The severe weather threat for Tornado Watch 194 continues.

   SUMMARY...A wind damage and isolated tornado threat may continue for
   several more hours, affecting parts of eastern Missouri into central
   and southern Illinois. A new watch may need to be considered to the
   east of WW 194.

   DISCUSSION...The latest hi-resolution radar imagery from St. Louis,
   MO shows a linear MCS moving eastward across eastern Missouri. An
   unstable airmass is situated from the line east-southeastward across
   south-central Illinois and into western Kentucky. In addition, the
   St. Louis WSR-88D VWP has 0-6 km shear around 45 knots with 0-3 km
   storm-relative helicity near 350 m2/s2. This may continue to support
   a severe threat over the next few hours, as the line crosses the
   Mississippi River. The severe threat may tend to develop
   southeastward toward far western Kentucky, where more instability is
   located. However, the threat is expected to become more isolated
   with time.
