Areas affected...Ohio Valley
Concerning...Severe potential...Watch possible
Valid 072336Z - 080030Z
Probability of Watch Issuance...60 percent
SUMMARY...Severe threat appears to be increasing across the southern
Ohio Valley this evening. New watch appears warranted and may be
issued by soon.
DISCUSSION...Persistent corridor of low-level confluence extends
along the confluence of the MS/OH River into southern IN. Agitated
cu field is gradually deepening across southern IL/IN into western
KY where MLCAPE values are in excess of 3000 J/kg. Given the strong,
deep-layer shear across this region, robust updrafts may evolve over
the next few hours. Supercell risk is increasing and a new ww
appears warranted.
