   ...THERE IS A SLGT RISK OF SVR TSTMS OVER PARTS OF THE MID ATLANTIC
   REGION FROM NERN NC TO SRN NJ...
   
   ...SYNOPSIS...
   POTENT EARLY SPRING CYCLONE WILL TRACK FROM THE SRN/CNTRL
   APPALACHIANS ACROSS THE MID ATLANTIC REGION AND THEN NEWD TO THE NEW
   ENGLAND COASTAL WATERS DURING MONDAY AND MONDAY NIGHT. AS THIS
   SYSTEM MOVES OUT OVER THE ATLANTIC...RISING MID LEVEL HEIGHTS WILL
   DEVELOP IN THE WAKE OF THE DISTURBANCE...FROM THE MIDWEST THROUGH
   THE GREAT LAKES AREAS BY EARLY TUESDAY. THE MID/UPPER LEVEL PATTERN
   WILL ALSO REMAIN PROGRESSIVE ACROSS THE WEST WHERE A STRONG AND
   EXTENSIVE UPPER WAVE WILL DEVELOP INLAND OVER THE PACIFIC
   NORTHWEST...AND THEN EWD ACROSS THE ROCKIES.
   
   DEEP LAYER CYCLONE IN THE EAST WILL BE THE PRIMARY SYSTEM DRIVING
   STRONG TO POTENTIALLY SEVERE TSTMS THIS PERIOD AS INTENSE DYNAMICS
   AND KINEMATICS AID LOW LEVEL MOISTURE TRANSPORT NWD INTO THE MID
   ATLANTIC COASTAL PLAIN. WRN TROUGH WILL ALSO PROVIDE SUFFICIENT
   INSTABILITY AND LIFT FOR WIDELY SCATTERED AFTERNOON AND EVENING
   TSTMS ACROSS THE INTERMOUNTAIN WEST AND NRN PLAINS. HOWEVER...WRN
   ACTIVITY IS EXPECTED TO REMAIN BELOW SEVERE LEVELS.
   
   ...NERN NC TO DELMARVA AND SRN NJ...
   AS DEEPENING/REDEVELOPING SFC LOW TRACKS ACROSS VA TO DELMARVA
   PENINSULA EARLY IN THE PERIOD...SWATH OF LOW 60S SFC DEWPOINTS ARE
   FCST TO SPREAD NWD FROM ERN NC TO CHESAPEAKE AND DELAWARE BAYS. THIS
   LOW LEVEL MOISTURE FLUX WILL OCCUR COINCIDENT WITH PRONOUNCED
   MID/UPPER LEVEL DRY SLOT WHICH MAY ALLOW FOR SOME BOUNDARY LAYER
   HEATING. LATEST MODELS CONTINUE EARLIER TRENDS INDICATING AT LEAST
   MODEST INSTABILITY DEVELOPING ACROSS THE REGION BY AFTERNOON. VERY
   STRONG FORCING FOR UPWARD MOTION WILL EXIST ACROSS THE INSTABILITY
   AXIS BENEATH LEFT FRONT QUADRANT OF MID/UPPER JET. TIGHT ISOTACH
   GRADIENT ACROSS THE NOSE OF THE JET CORE...AND APPROACH OF WEAKER
   MID LEVEL WINDS ASSOCIATED WITH MID/UPPER LOW...WILL RESULT IN
   STRONGEST DEEP LAYER SHEAR REMAINING CONFINED TO THE IMMEDIATE
   COASTAL AREAS. HOWEVER...MAGNITUDE OF ASCENT ACROSS THE REGION...
   AND POTENTIAL MESOSCALE FORCING ASSOCIATED WITH THE SFC LOW...SHOULD
   PROMOTE THE DEVELOPMENT OF SCATTERED ORGANIZED STORMS THROUGH THE
   DAY. GREATEST POTENTIAL FOR SUPERCELLS WILL BE NEAR THE COAST...AND
   NEAR THE SFC LOW/WARM FRONT WHERE WIND DAMAGE... HAIL...AND TORNADO
   THREATS WILL EXIST OVER A RELATIVELY SMALL GEOGRAPHIC AREA. OTHER
   CLUSTERS OF LESS ORGANIZED LOW-TOPPED CONVECTION...POSSIBLY
   PRODUCING HAIL...MAY OCCUR WITHIN/BENEATH THE COLD CORE LOW AS IT
   CROSSES THE REGION DURING PERIOD OF MAXIMUM DIURNAL HEATING.
