   Mesoscale Discussion 1096
   NWS Storm Prediction Center Norman OK
   0158 PM CDT Mon Jun 19 2017

   Areas affected...Interior southern New England...New Hampshire and
   western/northern Maine

   Concerning...Severe Thunderstorm Watch 354...355...

   Valid 191858Z - 192100Z

   The severe weather threat for Severe Thunderstorm Watch 354, 355

   SUMMARY...Thunderstorms accompanied by locally heavy rain, frequent
   lightning and potentially damaging wind gusts will overspread the
   region through 4-6 PM EDT.

   DISCUSSION...Insolation has warmed surface temperatures through the
   lower/middle 80s within a narrow pre-frontal corridor across
   interior southern New England through the higher terrain of
   western/northern Maine.  This appears to be contributing to mixed
   layer CAPE on the order of 1000-2000 J/kg, and likely will provide
   the focus for the most vigorous thunderstorm development through
   20-22Z.  This will be accompanied by the risk for potentially
   damaging surface gusts, particularly from near/northwest of
   Worcester through areas near/west and north of Manchester/Concord
   NH, where it appears that ambient southerly 850 mb flow has
   increased in excess of 40 kt.
