   The severe weather threat for Severe Thunderstorm Watch 218
   continues.

   SUMMARY...A strong to isolated severe threat, mainly in the form of
   damaging winds, should persist for a few more hours. These threats
   will diminish by early evening.

   DISCUSSION...Earlier discrete to semi-discrete cells have largely
   congealed into an emerging linear cluster from western CT into far
   southern NH. The linear segment will offer the best potential for
   damaging winds over the next couple hours across northern CT and MA,
   where surface temperatures in the low to mid 80s are prevalent.
   Marine-layer influence from Long Island Sound will curtail the
   southern extent of the severe potential, as well as earlier
   convection/marine influence near the coastal NH/ME portion of the
   watch. This suggests the severe-storm threat will diminish in the
   early evening.
