   THE LARGE/NEGATIVELY TILTED UPPER TROUGH OVER THE ERN U.S. EARLY IN
   THE PERIOD WILL CONTINUE LIFTING NEWD WITH TIME...WHILE THE OVERALL
   FLOW PATTERN OVER THE REMAINDER OF THE COUNTRY DEAMPLIFIES IN THE
   WAKE OF THIS FEATURE.
   
   AT THE SURFACE...A BROAD/WEAK LOW OVER THE GREAT LAKES REGION IS
   EXPECTED TO SHIFT NWD ACROSS ERN ONTARIO/WRN QUEBEC AND
   CONSOLIDATE/DEEPEN RAPIDLY -- BECOMING INCREASINGLY OCCLUDED WITH
   TIME.  ATTM...IT APPEARS THAT THE TRIPLE POINT SHOULD REMAIN NEAR OR
   JUST OFF THE MID-ATLANTIC COAST.  WITH THE WARM SECTOR THUS
   REMAINING PREDOMINANTLY OFFSHORE...AND ONLY WEAK INSTABILITY PROGGED
   AHEAD/NE OF THE OCCLUSION...THREAT FOR SEVERE WEATHER APPEARS LOW. 
   WHILE SOME PORTION OF NJ/SERN NY/SRN NEW ENGLAND MAY EVENTUALLY
   COMMAND LOW SEVERE PROBABILITY...THREAT APPEARS LOW/UNCERTAIN ENOUGH
   AT THIS POINT TO PRECLUDE INTRODUCTION OF A PROBABILITY AREA ATTM.
