Mesoscale Discussion 0308
   NWS Storm Prediction Center Norman OK
   1139 AM CDT Wed Apr 08 2020

   Areas affected...portions of northern and eastern KY...far southern
   OH...southern WV into western VA

   Concerning...Severe potential...Watch possible 

   Valid 081639Z - 081815Z

   Probability of Watch Issuance...60 percent

   SUMMARY...Widely scattered thunderstorms will continue to increase
   in intensity through this afternoon. Large hail and isolated
   damaging wind gusts will be the main threat associated with these
   storms.

   DISCUSSION...Isolated to widely scattered thunderstorms are
   developing ahead of a southward-advancing cold front from northern
   KY/IN into far southern OH and western WV. Strong heating ahead of
   the boundary has allowed temperatures to climb into the mid 60s to
   mid 70s with lwo 60s dewpoints across the region, resulting in
   MLCAPE from 500-1500 J/kg. Modestly steep midlevel lapse rates
   around 7-7.5 C/km and strong vertical shear, resulting in long,
   straight hodographs, will favor supercells capable of large hail.
   Furthermore, steepening low level lapse rates could increase
   potential for damaging wind gusts. This convection will track
   east/southeast through broad northwesterly flow regime, and may
   spread into western VA by late afternoon/early evening.
