   Concerning...Tornado Watch 187...

   Valid 160109Z - 160215Z

   The severe weather threat for Tornado Watch 187 continues.

   SUMMARY...Although damaging winds remain possible in the near term,
   a gradual weakening trend is expected over the next hour as a line
   of storm moves towards the Atlantic coast.

   DISCUSSION...Radar trends from KONX and KENX show a gradual
   weakening trend in the squall line that is progressing across
   southern NY, and into MA and CT, including areas south of WW 187.
   This trend is expected to continue as this line of storms moves into
   an environment characterized by more maritime influences with
   temperatures in the 60s and dewpoints in the 50s along the Atlantic
   coast and as diurnal cooling continues to help stabilize the inland
   boundary layer. However, recent GOES IR imagery has shown some
   individual storms and segments of the line cooling aloft in
   conjunction with an uptake in lightning activity, suggesting
   periodic and transient intensification, and thus a damaging wind
   threat, remains possible in the near term.
