   VALID 121200Z - 131200Z
   
   ...THERE IS A SLGT RISK OF SVR TSTMS FOR PARTS OF THE CNTRL HIGH AND
   SRN PLAINS...
   
   ...SYNOPSIS...
   A DAMPENING UPPER-LEVEL TROUGH WILL PROGRESS FROM ONTARIO/LK
   SUPERIOR TOWARDS HUDSON BAY/QUEBEC. QUASI-ZONAL FLOW REGIME IN THE
   MID-LEVELS WILL ENVELOP THE LEE OF THE ROCKIES...WITH A WEAK IMPULSE
   PROGGED TO CROSS WY TOWARDS THE BLACK HILLS/NEB PANHANDLE BY WED
   EVENING. QUASI-STATIONARY FRONT SHOULD REMAIN ACROSS THE SRN
   PLAINS...WITH AIR MASS MODIFICATION NW OF THE BOUNDARY OCCURRING AS
   LOW-LEVEL RETURN FLOW INCREASES IN THE LEE OF THE ROCKIES. 
   
   ...CNTRL HIGH AND SRN PLAINS...
   AN ACTIVE CONVECTIVE DAY APPEARS LIKELY TO UNFOLD WITH FAIRLY
   CONSISTENT SIGNALS IN MODEL GUIDANCE. A FEW TSTM CLUSTERS MAY BE
   ONGOING AT 12Z/TUE...ALONG AND N OF THE QUASI-STATIONARY FRONT
   EXPECTED TO BE DRAPED ACROSS N TX. ROBUST HEATING S OF THE FRONT
   ALONG WITH PERSISTENT LOW-LEVEL UPSLOPE N OF THE BOUNDARY SHOULD
   RESULT IN DIURNAL INVIGORATION OF TSTMS OVER MUCH OF THE SRN PLAINS
   AND ADJACENT TERRAIN. WITH MODERATE HIGH-LEVEL WLYS /GENERALLY N OF
   THE FRONT/...ORGANIZED CLUSTERS AND SOME EMBEDDED SUPERCELL
   STRUCTURES APPEAR PROBABLE WITH ASSOCIATED PRIMARY RISKS OF SEVERE
   HAIL/WIND. 
   
   FARTHER N...A RIBBON OF MIDDLE 40S TO LOWER 50S SURFACE DEW POINTS
   SHOULD BE DRAWN NWD TOWARDS THE BLACK HILLS. ALTHOUGH BUOYANCY MAY
   REMAIN MODEST...A BELT OF ENHANCED MID-LEVEL WLYS AND ASCENT
   ASSOCIATED WITH THE WEAK IMPULSE SHOULD COMPENSATE...YIELDING AT
   LEAST ISOLATED TSTM DEVELOPMENT BY LATE AFTERNOON/EARLY EVENING. THE
   DEEP-LAYER WIND PROFILE WILL BE FAVORABLE FOR SUPERCELLS WITH ALL
   SEVERE TYPES POSSIBLE.
