Mesoscale Discussion 1372
   NWS Storm Prediction Center Norman OK
   0119 PM CDT Sat Aug 01 2020

   Areas affected...eastern Kentucky...much of Ohio...much of West
   Virginia...and far southwestern Pennsylvania

   Concerning...Severe potential...Watch possible 

   Valid 011819Z - 011915Z

   Probability of Watch Issuance...40 percent

   SUMMARY...Deepening convection will pose a risk for damaging winds
   and perhaps a tornado or two through the afternoon.  A WW issuance
   is being considered.

   DISCUSSION...Convection across eastern Kentucky has gradually
   deepened and intensified over the past hour, partially in response
   to lift/ascent associated with a mid-level low over Illinois.  These
   storms are in a moderately buoyant airmass (1500-2500 J/kg MUCAPE),
   with deep shear of around 25-35 knots marginally favoring loose
   organization.  Weak low-level flow also favors outflow dominant
   storms, though some turning/veering with height may support
   occasional updraft rotation in persistent, cellular convection.  An
   east-to-west oriented warm front located from near DAY to near MRB
   may also aid in updraft rotation with cells that can favorably
   interact.  The overall scenario suggests potential for occasional
   wind damage and perhaps a tornado or two with stronger convection. 
   The nature of the threat may become substantial enough to require a
   WW issuance over the next couple of hours.  Convective trends are
   being monitored.
