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.
