Areas affected...Parts of southern IN...southwest
OH...northern/western KY...far southern IL/southeast MO

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

Valid 122029Z - 122200Z

Probability of Watch Issuance...20 percent

SUMMARY...Locally damaging wind will remain possible through late
afternoon.

DISCUSSION...A compact storm cluster is moving quickly eastward
across southern IN and adjacent western KY late this afternoon.
While convection associated with this cluster is not particularly well-organized, it has a history of producing localized near-severe
gusts, and also has a relatively strong cold pool. Strong downstream
heating has resulted in MLCAPE increasing above 2500 J/kg and
steepening low-level lapse rates. Deep-layer shear is weak, but
given the favorable buoyancy and presence of a propagating cold
pool, some threat for isolated damaging wind may accompany this
storm cluster as it continues to move eastward.=20

Other strong storms are ongoing across parts of western/central OH,
and also along the trailing outflow into far western KY into
southern IL and southeast MO. These storms will be capable of
producing localized damaging downburst winds, given favorable
buoyancy and large PW.
