   Mesoscale Discussion 0726
   NWS Storm Prediction Center Norman OK
   0612 PM CDT Wed Jun 13 2018

   Areas affected...Western and central New York and far northern
   Pennsylvania

   Concerning...Severe Thunderstorm Watch 175...

   Valid 132312Z - 140045Z

   The severe weather threat for Severe Thunderstorm Watch 175
   continues.

   SUMMARY...The severe weather threat continues for areas along and
   ahead of the front this evening. Severe weather intensity will wane
   after sunset.

   DISCUSSION...There are two primary areas of severe weather concern
   this evening near the eastern shore of Lake Ontario and in south
   central New York. While the northern area has been the most
   organized through the afternoon and early evening, expect this line
   to become increasingly disorganized as it interacts with an
   increasingly stable airmass to the east this evening. Additional
   cells are starting to develop in the more unstable airmass south of
   this activity. These cells may organize into a few strong to severe
   storms this evening given effective shear of 50 to 55 knots and
   MLCAPE around 1000 J/kg. Expect severe threat to wane across watch
   175 after sunset as the boundary layer stabilizes.
