   ...SYNOPSIS...
   BROAD CYCLONIC UPPER FLOW REGIME IS EXPECTED TO CONTINUE ACROSS THE
   NATION TODAY AND TONIGHT.  A COUPLE OF LOW AMPLITUDE SUBTROPICAL
   JETLETS EMBEDDED IN THE SWLY FLOW ALONG THE SRN PERIPHERY OF THE
   LONGWAVE TROUGH WILL TRANSLATE NEWD.  THE FIRST IMPULSE WILL TRAVEL
   FROM THE LOWER OH VLY THIS MORNING INTO THE MIDDLE ATLANTIC REGION
   BY AFTERNOON.  UPSTREAM...ANOTHER IMPULSE WILL MOVE FROM BAJA CA
   REGION INTO THE SRN HIGH PLAINS BY LATE TONIGHT.  IN THE LOWER
   LEVELS...A COLD FRONT WILL MOVE ACROSS THE NERN STATES AND MIDDLE
   ATLANTIC COAST THROUGH TONIGHT WHILE TAIL END OF THE SAME FRONT
   REMAINS QUASI-STATIONARY ACROSS THE SRN PLAINS.
   
   ...LOWER DELMARVA AND ERN NC...
   AIR MASS REMAINS VERY MOIST ACROSS THE REGION THIS MORNING AHEAD OF
   LEE TROUGH/BROKEN BAND OF TSTMS.  LOW CLOUDS/FOG SHOULD BEGIN TO
   THIN THIS MORNING...ALLOWING POCKETS OF HEATING.  MODIFYING 12Z GSO
   SOUNDING SUGGEST POTENTIAL FOR AROUND 2000 J/KG CAPE AND LITTLE
   CINH.  AS TAIL END OF UPSTREAM VORT MAX MOVES ACROSS THE REGION
   EARLY-MID AFTERNOON...ADDITIONAL TSTMS COULD DEVELOP...OR INTENSIFY
   WITHIN CURRENT BAND ACROSS SERN/EC VA/LOWER ERN MD SHORE AND ERN NC.
    VERTICAL SHEAR WILL BE JUST ENOUGH TO SUPPORT ORGANIZED CONVECTION
   WITH THE POTENTIAL FOR ISOLD DAMAGING WINDS AND PERHAPS A BRIEF
   TORNADO.  LARGE SCALE ASCENT WILL LIKELY DECREASE RAPIDLY BY EVENING
   AND THE STRONGER TSTMS SHOULD DIMINISH AND MOVE OFF THE COAST. 
   
   ...SRN HIGH PLAINS...
   ELEVATED CONVECTION WILL INCREASE THIS EVENING INTO THE OVERNIGHT
   HOURS AS LARGE SCALE ASCENT SPREADS DOWNSTREAM FROM APPROACHING
   SUBTROPICAL IMPULSE.  MUCAPES WILL GENERALLY BE UNDER 750 J/KG AND 
   TSTMS ARE EXPECTED TO BE SUB-SEVERE...THOUGH SMALL HAIL CANNOT BE
   RULED OUT IN THE STRONGER CELLS.  TSTMS SHOULD SPREAD RAPIDLY NEWD
   INTO PARTS OF THE SRN PLAINS LATER TONIGHT.
