   ...SYNOPSIS...
   PATTERN WILL REMAIN PROGRESSIVE THIS PERIOD...WITH NRN STREAM
   TROUGH NOW OVER THE DAKOTAS MOVING TO THE UPR GRT LKS AS SRN BRANCH
   IMPULSE NOW OVER NM CONTINUES E/ENE INTO MO/AR.   FARTHER S...GULF
   CST CLOSED LOW SHOULD SETTLE S INTO THE NRN GULF AS HEIGHTS RISE
   OVER THE APPALACHIANS.
   
   AT LOWER LEVELS...COLD FRONT ASSOCIATED WITH NRN PLNS SYSTEM WILL
   CONTINUE S AND E...REACHING AN ORD/LIT/ACT LINE BY 12Z TUESDAY. 
   THERMAL LOW/PREFRONTAL TROUGH NOW OVER WRN OK/NW TX SHOULD SETTLE
   S/E AHEAD OF THE FRONT LATER TODAY. 
   
   ...SRN PLNS...
   STRONG SURFACE HEATING SHOULD OCCUR TODAY AHEAD OF COLD FRONT OVER
   THE SRN PLNS...WHERE MODERATE BOUNDARY LAYER MOISTURE WILL PERSIST.
   RESULTING DESTABILIZATION AND CONVERGENCE ALONG FRONT/PREFRONTAL
   TROUGH SHOULD LEAD TO STORM DEVELOPMENT ALONG THESE FEATURES LATE
   THIS AFTERNOON.
   
   PRESENCE OF UPPER LOW OVER THE GULF CST WILL LIMIT STRENGTH OF LOW
   LEVEL INFLOW/DEEP SHEAR OVER THE SRN PLNS.  BUT THE LOW WILL ALSO
   ENHANCE DEGREE OF UPPER DIFFLUENCE OVER THE REGION.  IN ADDITION...
   SOME INCREASE IN MID LEVEL WLY FLOW WILL OCCUR AS NM IMPULSE
   CONTINUES EWD.  THUS...SETUP SHOULD BECOME SUPPORTIVE OF STRONG
   ORGANIZED STORMS...INCLUDING A FEW SUPERCELLS...FROM SRN KS SWD
   INTO N TX.  SUPERCELL THREAT SHOULD BE HIGHEST FROM S CNTRL OK INTO
   NW TX...WHERE GREATEST DEGREE OF DIRECTIONAL SHEAR/INSTABILITY
   SHOULD COEXIST. 
   
   GIVEN LINEAR FORCING AND PRESENCE OF DRY AIR/MODERATE TO STRONG
   CONVECTIVE DOWNDRAFT POTENTIAL...ACTIVITY SHOULD FAIRLY QUICKLY
   MERGE INTO QUASI-LINEAR MCS...WITH HAIL/LOCALLY DAMAGING WIND
   POSSIBLE...MAINLY DURING EARLY STAGES OF STORM DEVELOPMENT.  SOME
   THREAT FOR HAIL MAY...HOWEVER...PERSIST EVEN AFTER STORMS ARE
   UNDERCUT BY ADVANCING WEDGE OF POST-FRONTAL AIR.  THE CONVECTIVE
   SYSTEM SHOULD BACK-BUILD SWWD LATER THIS EVENING...PERHAPS AS FAR
   S AS CNTRL TX.  THE SEVERE THREAT SHOULD DIMINISH WITH DIURNAL
   COOLING AND CONTINUED UNDERCUTTING BY ADVANCING COLD AIR MASS LATER
   TONIGHT.
   
   ...UPR MS VLY/UPR GRT LKS...
   A SEPARATE AREA OF MODERATE TO STRONG SYNOPTIC SCALE FORCING/
   FRONTOGENESIS WILL AFFECT SE MN/THE NWRN HALF OF WI AND UPR MI
   LATER TODAY AS NRN STREAM IMPULSE NOW OVER ERN NEB/SD TRACKS NEWD.
   WHILE CLOUDS WILL LIMIT HEATING OVER THE REGION THROUGHOUT THE
   DAY...STRONG FRONTAL ASCENT OF WEAKLY UNSTABLE AIR MASS MAY SUPPORT
   A NARROW LINE OF FORCED CONVECTION/THUNDER.  GIVEN 40+ KT
   UNIDIRECTIONAL DEEP SHEAR...THE ACTIVITY MAY POSE A THREAT FOR
   DAMAGING WIND/SMALL HAIL THIS AFTERNOON THROUGH EARLY TONIGHT...AND
   MAY REQUIRE AN UPGRADE TO SLIGHT RISK IN THE 20Z OUTLOOK.
   
   ...FL...
   ENVIRONMENT OF MODERATE TO STRONG INSTABILITY AND VERY WEAK SHEAR 
   LIKELY TO SUPPORT A FEW SEVERE PULSE STORMS OVER THE FL PENINSULA
   LATER TODAY.  THREAT FARTHER N INTO GA APPEARS LIMITED GIVEN
   EXTENSIVE DEGREE OF OVERTURNING WHICH OCCURRED THERE YESTERDAY.
