   ...DISCUSSION...
   
   ...D4 /SUN JUN 8TH/...
   
   THE ECMWF CONTINUES TO INDICATE A SHORT WAVE TROUGH WILL MOVE FROM
   THE CNTRL ROCKIES INTO NRN AND CNTRL PLAINS...DIFFERENT FROM THAT OF
   THE GFS WHICH DEPICTS A FLATTER SWLY FLOW REGIME FROM THE CNTRL
   ROCKIES INTO UPPER GREAT LAKES.  IN THE LOW LEVELS...THERE IS MORE
   AGREEMENT IN THE ORIENTATION AND LOCATION OF PRIMARY BAROCLINIC ZONE
   WHICH WILL LIKELY EXTEND FROM THE UPPER MIDWEST OR SRN GREAT LAKES
   SWWD INTO THE CNTRL OR SRN HIGH PLAINS.  
   
   THE MORE AMPLIFIED ECMWF SOLUTION INDICATES THAT STRONGER VERTICAL
   SHEAR WILL EXIST SWD INTO WARM SECTOR...WHILE THE GFS SUGGESTS THAT
   THE STRONGER WIND FIELDS WILL REMAIN LARGELY TO THE N OF FRONTAL
   ZONE.  WHILE A FEW SEVERE STORMS WILL BE POSSIBLE ALONG THE FRONTAL
   ZONE...THE OVERALL THREAT REMAINS UNCERTAIN GIVEN THE DIFFERENCES IN
   THE UPPER AIR PATTERN AND DEGREE OF VERTICAL SHEAR ALONG/S OF
   FRONTAL ZONE.  THUS...NO AREA WILL BE HIGHLIGHTED ATTM.
   
   ...D5 /MON JUN 9TH/ THROUGH D8 /THU JUN 12TH/...
   
   LATEST MEDIUM-RANGE GUIDANCE IS RELATIVELY CONSISTENT IN INDICATING
   THAT A LONG WAVE TROUGH WILL PERSIST FROM PORTIONS OF THE WRN INTO
   CNTRL STATES WITH RIDGING IN THE E.  HOWEVER...CONSIDERABLE
   DIFFERENCES EXIST IN THE MOVEMENT OF SHORTER WAVELENGTH FEATURES AND
   THEIR ASSOCIATED SURFACE FRONTAL SYSTEMS.  GIVEN THE LOW
   PREDICTABILITY OF THE PATTERN...NO ADDITIONAL AREAS WILL BE
   DELINEATED.
