   Areas affected...west-central IL into far northeast and east-central

   Concerning...Severe Thunderstorm Watch 168...

   Valid 102130Z - 102300Z

   The severe weather threat for Severe Thunderstorm Watch 168

   SUMMARY...Isolated storms have developed across parts of
   west-central IL near the western edge of WW 168. Should convective
   trends warrant, a westward expansion of WW 168 may be needed.

   DISCUSSION...An outflow boundary is draped across the MCD area, left
   behind by early MCD/bow echo now tracking across east-central IL and
   IN. Storms have begun to develop in the vicinity of this boundary
   across parts of western IL from Adams County to SPI. Furthermore, a
   healthy CU field is present in visible satellite imagery across
   parts of northeast MO and west-central IL along axis of great
   instability and on the southern periphery of modest deep layer
   shear. Should convection intensify and become better organized 
   along the outflow boundary and/or develop in the warm sector ahead
   of the boundary, WW 168 may need to be expanded westward to address
   this threat. Convective trends will be monitored.
