   Areas affected...much of Long Island NY

   Concerning...Severe Thunderstorm Watch 538...

   Valid 222303Z - 230000Z

   The severe weather threat for Severe Thunderstorm Watch 538
   continues.

   SUMMARY...Strong, damaging winds will be possible across much of
   Long Island over the next hour.

   DISCUSSION...A bowing segment that moved across, and produced
   widespread measured severe/wind damage, the Philadelphia metro
   vicinity is now moving toward Long Island at around 50 kts and will
   impact much of the Long Island vicinity over the next hour. Radar
   trends continue to indicate strong velocity signatures of around
   60-70 kt around 3 kft. Additionally, the VWP data from KDIX 88-D
   showed 55 kt westerly winds just a few hundred feet ARL. As such,
   severe wind gusts capable of producing damage will be possible
   across much of Long Island over the next hour.
