Areas affected...Central/southern IN into southern IL

Concerning...Severe potential...Watch unlikely=20

Valid 271836Z - 272030Z

Probability of Watch Issuance...20 percent

SUMMARY...Isolated strong/damaging gusts are possible this
afternoon.

DISCUSSION...A band of convection is moving eastward across parts of
west-central IN into southern IL. While this convection is not
particularly organized, a wind gust to 54 kt and some wind damage
was recently observed in Mattoon, IL. Additional downstream heating
and steep low-level lapse rates will continue to support a threat
for strong to localized severe gusts as these storms move eastward
this afternoon. Modest unidirectional southwesterly low-level flow
could support some loosely organized clustering with time, but weak
vertical shear is currently expected to limit the overall coverage
and magnitude of the severe threat. Trends will be monitored for any
uptick in storm organization this afternoon.
