   Mesoscale Discussion 1326
   NWS Storm Prediction Center Norman OK
   0543 PM CDT Sun Jul 16 2017

   Areas affected...northern and central Ohio

   Concerning...Severe potential...Watch unlikely 

   Valid 162243Z - 170015Z

   Probability of Watch Issuance...5 percent

   SUMMARY...A few instances of downburst winds and hail will remain
   possible over northern and central Ohio through early evening. Any
   severe events are expected to remain too sparse and overall threat
   too marginal for a WW issuance.

   DISCUSSION...Isolated storms continue developing along a slow-moving
   cold front and in association with lake breeze across northern OH.
   Atmosphere is moderately unstable with around 1500 J/kg MLCAPE and
   6.5 C/km mid-level lapse rates. The storms are embedded within
   modest west-northwesterly deep-layer winds with weak effective shear
   supportive of multicells. Activity is diurnally driven, and will
   pose a modest risk for hail and downbursts winds as cells develop
   southeast next few hours. A gradual diminishing trend should occur
   by 02Z with onset of nocturnal cooling.
