   ...SYNOPSIS...
   BROAD TROUGH OVER NORTHWEST QUARTER OF CONUS WITH UPPER LOW CENTER
   INITIALLY SRN ALBERTA WILL SHIFT EWD DURING FORECAST PERIOD AS LOW
   CENTER MOVES NEWD INTO CENTRAL SASKATCHEWAN. A RATHER DEEP SURFACE
   LOW ACROSS SRN SASKATCHEWAN SHIFTS EWD AS TRAILING COLD FRONT SAT
   AM OVER ERN MT SWWD INTO UT  MOVES ACROSS NRN PLAINS SWWD INTO
   CENTRAL ROCKIES BY SAT NIGHT. LEE TROUGH SHIFTS EWD AHEAD OF COLD
   FRONT EXTENDING FROM CENTRAL SD TO WRN KS BY SAT AFTERNOON. STRONG
   30-40 KT SLY FLOW E OF LEE TROUGH WILL TRANSPORT A VERY MOIST AND
   UNSTABLE AIRMASS NWD THRU ERN DAKOTAS AHEAD OF THE COLD FRONT.
   
   ..DAKOTAS/NWRN MN...
   AN ELEVATED MIX LAYER WITH LAPSE RATES IN EXCESS OF 8C/KM WILL
   OVERSPREAD MUCH OF PLAINS TO E OF COLD FRONT SATURDAY AS STRONGER
   SWLY FLOW ASSOCIATED WITH APPROACHING UPPER TROUGH DEVELOPS INTO
   NRN PLAINS.  EFFECT WILL BE TO INITIALLY PROVIDE A LID TO SURFACE
   BASED CONVECTIVE DEVELOPMENT ALONG WITH ENHANCING INSTABILITY.  BY
   MID AFTERNOON WITH DEWPOINTS WELL INTO THE 60S AND TEMPERATURES IN
   THE 80S/LOW 90S...MLCAPES ABOVE 2500 J/KG WILL BE COMMON E OF DRY
   LINE ACROSS  DAKOTAS INTO NEB. CAP SHOULD WEAKEN SUFFICIENTLY BY
   MID/LATE AFTERNOON AIDED BY SURFACE CONVERGENCE ASSOCIATED WITH
   COLD FRONT/DRY LINE...FOR SURFACE BASED SEVERE THUNDERSTORMS TO
   FORM DAKOTAS. 
   
   DEEP LAYER SHEAR...SFC-6KM...FROM 30-40KT WILL BE SUFFICIENT FOR
   ORGANIZED THUNDERSTORM DEVELOPMENT...POSSIBLY EVOLVING INTO SHORT
   LINE/BOWS AS ACTIVITY MOVES INTO NWRN MN BY EVENING.  SUPERCELLS
   ARE LIKELY EARLY ON IN CONVECTIVE DEVELOPMENT...WITH ISOLATED
   TORNADOES POSSIBLE ALONG WITH ENHANCED THREAT OF LARGE HAIL AND
   DAMAGING DOWNBURST WINDS GIVEN THE EXPECTED VERY UNSTABLE AIRMASS.
   
   ...CENTRAL PLAINS...
   
   CAP WILL BE SOMEWHAT MORE EFFECTIVE IN SUPPRESSING SURFACE BASED
   STORMS FURTHER S ALONG DRY LINE.  HOWEVER WITH AFTERNOON
   TEMPERATURES LIKELY TO RISE  WELL INTO THE 90S VICINITY  DRY
   LINE...AT LEAST ISOLATED SEVERE STORMS SHOULD DEVELOP BY LATE
   AFTERNOON.  THE VERY UNSTABLE AIRMASS COUPLED WITH WEAKER MID/UPPER
   LEVEL FLOW...SUGGEST SEVERE THREAT WILL BE MORE ISOLATED WITH
   PULSE DOWNBURST WINDS AND LARGE HAIL.
