   ...SYNOPSIS...
   LARGE SCALE TROUGH OVER NWRN QUARTER OF CONUS DELIVERS A STRONG
   MID/UPPER LEVEL WIND MAX EWD ACROSS NRN PLAINS AS UPSTREAM S/WV
   DIGS SEWD INTO PAC NW THIS FORECAST PERIOD.  THE DEEP/VERTICALLY
   STACKED LOW OVER SASKATCHEWAN MOVES SLOWLY NEWD AS THE ASSOCIATED
   COLD FRONT PUSHING EWD ALONG NRN MN/CANADA BORDER THEN TRAILS SWWD 
   AND BECOMES QUASISTATIONARY INTO CENTRAL SD AND THEN WSWWD INTO NRN
   UT.  SECONDARY SURFACE LOW DEVELOPS OVER SD NEAR INTERSECTION OF
   FRONTAL BOUNDARY  AND DRY LINE WHICH EXTENDS SWD THRU CENTRAL
   NEB/KS INTO SWRN TX.
   
   ....ERN SD/NE AND WRN IA/MN...
   STRONG 40-50KT SLY LOW LEVEL JET FROM CENTRAL KS INTO WRN MN
   COUPLED WITH 50-60 KT 500MB WIND MAX ROTATING EWD ACROSS DAKOTAS
   DURING AFTERNOON WILL PROVIDE POTENT KINEMATICS FOR SEVERE
   THUNDERSTORMS ACROSS THIS AREA BY LATE AFTERNOON/EVENING.  VERY
   MOIST AND EXTREMELY UNSTABLE AIRMASS WITH MLCAPES AOA 4000 J/KG TO
   EAST OF DRY LINE COINCIDENT WITH LAPSE RATES OF AROUND 8C/KM ABOVE
   THE CAPPING INVERSION WILL PROVIDE POTENTIAL FOR EXPLOSIVE SEVERE
   THUNDERSTORM DEVELOPMENT BY MID/LATE AFTERNOON WHEN CAP WILL WEAKEN
   SUFFICIENTLY.  INITIATION MOST LIKELY VICINITY OF DRY LINE WHERE
   TEMPERATURES EXPECTED TO RISE WELL INTO THE 90S AND IN THE
   CONVERGENCE E/NE OF SURFACE LOW OVER CENTRAL SD AND ALONG
   QUASISTATIONARY FRONTAL BOUNDARY NEWD INTO MN.
   
   VEERING LOW LEVEL SHEAR PROFILES WITH HELICITIES 200-300 MS/S2 ON
   ETA MODEL SOUNDINGS ACROSS MUCH OF MDT RISK AREA BY MID AFTERNOON
   VICINITY LOW LEVEL JET...INDICATE SUPERCELL DEVELOPMENT LIKELY.  IN
   ADDITION TO POTENTIAL FOR LARGE HAIL...SHEAR SUPPORTS TORNADIC
   SUPERCELLS. STORMS WILL LIKELY EVOLVE INTO ONE OR MORE SEVERE MCS'S
   DURING EVENING AS ACTIVITY MOVES E/NEWD ACROSS SRN MN/IA WITH
   INCREASING WIND DAMAGE THREAT AS CONVECTION DEVELOPS BOWS/SHORT
   LINES.
   
   ...CENTRAL PLAINS...
   CAPPING WILL GRADUALLY BECOME MORE OF A FACTOR ACROSS DRY LINE FROM
   SRN NEB SWD. HOWEVER STRONG HEATING AND VERY UNSTABLE AIRMASS DOES
   SUPPORT AT LEAST ISOLATED SEVERE THUNDERSTORM THREAT VICINITY OF
   DRY LINE BY LATE/AFTERNOON AND EVENING.  VEERING LOW LEVEL SHEAR
   PROFILES DO SUPPORT SUPERCELL POTENTIAL,  ALTHOUGH THE
   HIGHER CLOUD BASES SHOULD CONFINE THREAT TO PRIMARILY LARGE HAIL
   AND DOWNBURST WINDS.
