   ...SYNOPSIS...
   HIGHLY AMPLIFIED LARGE-SCALE PATTERN IS FORECAST DURING THE DAY 2
   PERIOD WITH A SLOW EWD PROGRESSION OF MID-LEVEL TROUGH THROUGH THE
   GREAT LAKES AND MS/OH VALLEYS. IN THE W...NEXT UPSTREAM TROUGH WILL
   APPROACH THE PACIFIC NW COAST BY TUESDAY MORNING. AT THE SURFACE...
   ELONGATED AND NEARLY STATIONARY RIDGE FROM THE CANADIAN MARITIMES
   SWWD ALONG THE LEE OF THE APPALACHIANS WILL EFFECTIVELY STALL THE
   EWD PROGRESSION OF SYNOPTIC COLD FRONT...ALTHOUGH A SWD PUSH WILL
   CONTINUE INTO THE NRN GULF OF MEXICO.
   
   ...ERN KS/WRN MO...
   ALTHOUGH BOUNDARY-LAYER SHOULD REMAIN QUITE DRY WITH DEWPOINTS IN
   THE 30S AND 40S...PRESENCE OF COLD MID-LEVEL TEMPERATURES /-26 TO
   -30C AT 500 MB/ AND STRONG DIABATIC HEATING SHOULD CONTRIBUTE TO
   STEEP LOW TO MID-LEVEL LAPSE RATES AND WEAK INSTABILITY. APPROACH OF
   VORTICITY MAX TRANSLATING SEWD INTO MEAN TROUGH BASE COUPLED WITH
   ASSOCIATED WEAK SURFACE WIND SHIFT MAY BE SUFFICIENT TO INITIATE A
   FEW LOW-TOPPED STORMS BY AFTERNOON. SOME OF THE MORE VIGOROUS STORMS
   MAY PRODUCE HAIL APPROACHING SEVERE LEVELS OWING TO THE COLD
   THERMODYNAMIC PROFILES. ANY DEVELOPMENT SHOULD WEAKEN BY AFTERNOON
   AS BOUNDARY LAYER COOLS AND STABILIZES.
   
   ...CNTRL/ERN GULF COAST...
   WARM SECTOR BETWEEN SWD MOVING COLD FRONT AND DAMMING BOUNDARY
   ASSOCIATED WITH AFOREMENTIONED SURFACE RIDGE IS EXPECTED TO BE
   FAIRLY SMALL BY AFTERNOON AND GENERALLY CONFINED TO SRN MS AND
   CNTRL/WRN AL/FL PNHDL. HERE...TEMPERATURES IN THE 70S AND DEWPOINTS
   IN THE 50S SHOULD CONTRIBUTE TO WEAK INSTABILITY WITH MLCAPES
   APPROACHING 500 J/KG. HOWEVER...WEAK/VEERED LOW-LEVEL WINDS AND ONLY
   MODEST...ZONAL MID-LEVEL FLOW WILL LIMIT VERTICAL WIND SHEAR AND
   PRECLUDE ANY SEVERE WEATHER THREAT.
