   Mesoscale Discussion 1764
   NWS Storm Prediction Center Norman OK
   0846 PM CST Sun Nov 05 2017

   Areas affected...southern Indiana...southwest Ohio and northern
   Kentucky

   Concerning...Severe Thunderstorm Watch 515...

   Valid 060246Z - 060445Z

   The severe weather threat for Severe Thunderstorm Watch 515
   continues.

   SUMMARY...Threat for mainly a few strong to damaging wind gusts will
   persist through 04Z over a portion of the Ohio Valley, but overall
   threat is expected to become more marginal with time. Per
   coordination with Wilmington and Indianapolis, most of the remainder
   of WW 515 will be cancelled at 03Z with a small part remaining over
   extreme southern Indiana and northern Kentucky.

   DISCUSSION...Broken line of storms extending from southern OH into
   southern IN continues moving southward while individual elements
   within the line move more rapidly east-southeast. The thermodyamic
   environment is becoming increasingly marginal with MLCAPE generally
   at or below 500 J/kg. General trend has been for storms to become
   less organized. This is expected to continue as the boundary layer
   stabilizes and the low-level jet veers with time. However, given the
   very strong kinematic environment, occasional organized structures
   remain possible next hour or so.
