   Concerning...Tornado Watch 183...

   Valid 290055Z - 290230Z

   The severe weather threat for Tornado Watch 183 continues.

   SUMMARY...Scattered supercells will continue this evening,
   especially across the southern half of ww183.

   DISCUSSION...Scattered supercells have developed and oriented
   themselves along a corridor from near SLN-STJ. This activity has
   matured within a strongly sheared environment (0-6km), but only
   modest 0-3km SRH. 00z sounding from TOP suggests weak capping
   persists just above 850mb, but very steep lapse rates exist and
   large hail will continue to be generated within the more robust
   updrafts. Some increase in 850mb flow is expected over the next few
   hours, but the primary LLJ should focus across northern IL into the
   eastern U.P. of MI. This activity should spread northeast into
   northwest MO over the next several hours, just ahead of the surging
   cold front. While some additional convection may be generated along
   the synoptic boundary, the primary concern should be with the
   ongoing supercells.
