   --- SYNOPSIS ---
   IN MID/UPPER LEVELS...LARGE SCALE PATTERN WILL REMAIN DOMINATED BY
   HIGH-AMPLITUDE AND POSITIVELY TILTED TROUGH FROM HUDSON BAY REGION
   SWWD TO NRN MEX.  AS SERIES OF LOW-AMPLITUDE SHORTWAVES MOVE
   THROUGH ASSOCIATED CYCLONIC JET BELT...MEAN TROUGH WILL DRIFT EWD
   ...REACHING FROM NERN ONT ACROSS LS AND SRN PLAINS TO COAHUILA BY
   END OF PERIOD.  
   
   AT SURFACE...STRONG CYCLONE NOW ANALYZED OVER SERN WI IS FORECAST
   TO EJECT NEWD ACROSS LM/LOWER MI/LH...TO WRN QUE BY 29/12Z. 
   TRAILING COLD FRONT WILL SWEEP EWD ACROSS MS VALLEY AND NWRN
   GULF...REACHING WRN PA...SRN APPALACHIANS AND BAY OF CAMPECHE BY
   SATURDAY MORNING.  
    
   --- MI/OH TO LOWER MS VALLEY ---
   WITHIN BROAD BAND OF NEAR-FRONTAL PRECIP FROM AR TO MI...WIDELY
   SCATTERED TSTMS SHOULD DEVELOP EPISODICALLY AND IN LINES OR
   CLUSTERS.  GREATEST CONVECTIVE COVERAGE SHOULD BE DIURNAL. 
   AVAILABLE RAOBS AND ETA-KF/RUC FORECAST SOUNDINGS INDICATE
   COMBINATION OF MARGINAL BOUNDARY LAYER MOISTURE...SMALL MIDLEVEL
   LAPSE RATES AND CINH WILL SIGNIFICANTLY LIMIT POTENTIAL FOR LONG-
   LIVED TSTMS ACROSS MUCH OF AREA.  HOWEVER...POCKETS OF SBCAPE OR
   VERY NEARLY SBCAPE IN 500-1000 J/KG RANGE MAY FORM WITH DIURNAL
   HEATING ACROSS CATEGORICAL SLGT RISK AREA.  DEEPEST CONVECTION WILL
   HAVE POTENTIAL TO PRODUCE DAMAGING WIND AND MARGINALLY SEVERE HAIL.
   
   GIVEN STRENGTH OF ENVIRONMENTAL FLOW JUST OFF SURFACE -- E.G. 40-50
   KT AT 850 MB FROM WRN TN NNEWD -- STRONGEST DOWNDRAFTS SHOULD BE
   ABLE TO TRANSPORT CONSIDERABLE MOMENTUM TO SURFACE.  DESPITE NEARLY
   UNIDIRECTIONAL VERTICAL WIND PROFILES ACROSS REGION...STRONG DEEP-
   LAYER SPEED SHEAR STILL IS EXPECTED AND A FEW ISOLATED SUPERCELLS
   MAY DEVELOP WITHIN CONVECTIVE BAND.
