   MESOSCALE DISCUSSION 0072
   NWS STORM PREDICTION CENTER NORMAN OK
   1144 PM CST TUE FEB 04 2014

   AREAS AFFECTED...SERN PA...NJ...NYC/WRN LONG ISLAND

   CONCERNING...FREEZING RAIN 

   VALID 050544Z - 051045Z

   SUMMARY...MODERATE FREEZING RAIN WILL SPREAD ACROSS SOUTHEASTERN PA
   TOWARD WRN LONG ISLAND OVER THE NEXT FEW HOURS.  RAIN RATES WILL
   EXCEED 0.10 INCHES PER HOUR.  SIGNIFICANT ICING IS EXPECTED.

   DISCUSSION...STRONG LOW LEVEL WARM ADVECTION AHEAD OF TRANSITORY
   WARM CONVEYOR IS FOCUSING ASCENT ACROSS THE DELMARVA INTO THE NRN
   MIDDLE ATLANTIC REGION EARLY THIS MORNING.  PRECIPITATION IS RAPIDLY
   DEVELOPING/SPREADING NEWD ACROSS THIS REGION AND THERE IS INCREASING
   CONFIDENCE THAT A NARROW CORRIDOR OF MODERATE FREEZING RAIN WILL
   EVOLVE SOON ALONG THE I-95 CORRIDOR FROM PHL-JFK AND PORTIONS OF WRN
   LONG ISLAND.  IT APPEARS IMMEDIATE COASTAL MONMOUTH COUNTY NJ SOUTH
   MAY STRUGGLE TO MAINTAIN SUB-FREEZING TEMPERATURES.  THEREFORE THE
   GREATEST RISK FOR SIGNIFICANT ICING SHOULD BE NOTED JUST INLAND AND
   ACROSS LONG ISLAND.  SLEET WILL BE MORE COMMON ACROSS NRN NJ AND
   COASTAL SRN NEW ENGLAND WHERE BOUNDARY LAYER IS CONSIDERABLY COLDER
   ATTM.
