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.
