Areas affected...southern Indiana into southwest Ohio

Concerning...Severe potential...Watch likely 

Valid 020037Z - 020200Z

Probability of Watch Issuance...95 percent

SUMMARY...Thunderstorm coverage and intensity is expected to
increase this evening and overnight with a primary threat for large
hail and damaging wind gusts.

DISCUSSION...Thunderstorm coverage is increasing across central
Illinois with these storms eventually moving into Indiana later this
evening. Additional development is likely farther east into Indiana
and Ohio. Most of these storms will likely remain north of the warm
front where storms will predominantly be elevated with a threat for
large hail and isolated wind gusts. The 00Z ILN RAOB shows shear
which will support supercells and a threat for large hail and
potentially some very large hail. 

Initially the tornado threat should remain limited given the
majority of storms should be north of the warm front. However, after
midnight, storms are expected to develop/move into areas south of
the warm front where the tornado threat will be greater. A severe
thunderstorm watch will be issued for the initial threat and trends
will be monitored if a tornado watch is needed for the activity
later tonight.
