   MESOSCALE DISCUSSION 0660
   NWS STORM PREDICTION CENTER NORMAN OK
   0308 PM CDT THU MAY 22 2014

   AREAS AFFECTED...ERN NY TO ERN VA

   CONCERNING...SEVERE THUNDERSTORM WATCH 172...174...

   VALID 222008Z - 222145Z

   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH
   172...174...CONTINUES.

   SUMMARY...SCATTERED STORMS WITH SEVERE HAIL AS THE PRIMARY HAZARD
   SHOULD PERSIST FROM THE HUDSON VALLEY SWD TOWARDS THE VA TIDEWATER
   INTO THE EVENING. A SUBSTANTIALLY MORE STABLE AIR MASS TO THE EAST
   IN SRN NEW ENGLAND WILL PRECLUDE ADDITIONAL WW ISSUANCES.

   DISCUSSION...SCATTERED STORMS WITH A HISTORY OF SEVERE HAIL ARE
   ONGOING ACROSS BOTH OF THE WW/S. THE MOST INTENSE SUPERCELL W/NW OF
   ALB HAS PRODUCED SIGNIFICANT-SIZED LARGE HAIL AND STRONG ROTATIONAL
   SIGNATURES SUGGESTIVE OF A TORNADO. ALTHOUGH LOW-LEVEL WINDS ARE
   WEAK IN ALB VWP DATA...SUBSTANTIAL VEERING WITH HEIGHT AND AN ALMOST
   DUE SOUTH STORM MOTION YIELDS 0-1 KM SRH AROUND 100 M2/S2. WITH THIS
   STORM RIDING ALONG A N/S-ORIENTED WARM FRONT...LOCALIZED TORNADO
   POTENTIAL MAY CONTINUE THROUGH ABOUT 22Z.

   E OF THE HUDSON VALLEY...SURFACE TEMPERATURES ARE QUITE COOLER /IN
   THE 50S/ ACROSS SRN NEW ENGLAND. THIS SUGGESTS SEVERE THREAT SHOULD
   REMAINED CONFINED FROM NY WEST AND SOUTH.
