Mesoscale Discussion 1667
   NWS Storm Prediction Center Norman OK
   1154 PM CDT Tue Sep 01 2020

   Areas affected...Western/central Kentucky and far southern Indiana

   Concerning...Severe potential...Watch unlikely 

   Valid 020454Z - 020630Z

   Probability of Watch Issuance...20 percent

   SUMMARY...A low risk for locally damaging winds and/or a brief
   tornado may exist across western into central Kentucky into far
   southern Indiana into the overnight.

   DISCUSSION...A linearly organized band of convection, albeit with a
   general recent diminishing trend in lightning flashes, may persist
   east-northeastward across western into central Kentucky overnight.
   Latest WSR-88D VWP data from KHPX/Fort Campbell, KY supports as much
   as 200 m2/s2 of 0-1 km SRH. This degree of low-level shear will
   support the possibility of evolving bows and a possibly a few
   embedded mesovortices. Nocturnal influences on the boundary layer
   with increasing CINH and weak parcel accelerations should limit the
   overall severe potential, but locally strong wind gusts and/or a
   brief tornado cannot be ruled out early in the overnight.
