   Areas affected...southern NY into southern New England

   Concerning...Severe Thunderstorm Watch 489...

   Valid 301759Z - 301930Z

   The severe weather threat for Severe Thunderstorm Watch 489

   SUMMARY...A line of intense storms will shift east across southern
   New England and Southern New York/portions of Long Island the next
   couple of hours. Swaths of wind damage will accompany this activity.

   DISCUSSION...A well organized bowing segment over CT will continue
   to shift east at around 35-40 kt the next couple of hours. This
   activity has a long history of producing wind damage, and this trend
   is expected to continue as the bow moves across CT into RI and
   southern MA through 4pm EDT.

   An area of convection to the southwest of the bow continues to
   become better organized from southern NY into western CT. This
   activity should also continue generally eastward over the next
   couple of hours and may impact portions of Long Island. Damaging
   gusts may also accompany this activity.
