   ...THERE IS A SLGT RISK OF SVR TSTMS ACROSS PORTIONS OF THE NRN
   ROCKIES AND NRN PLAINS...
   
   ...NRN ROCKIES/NRN PLAINS...
   
   ONGOING CONVECTION ACROSS ERN MT APPEARS TO BE ASSOCIATED WITH A
   SHORTWAVE TROUGH THAT SHOULD MOVE INTO THE DAKOTAS BY 18Z.  THIS
   FEATURE SHOULD SLOWLY WEAKEN AS IT ENCOUNTERS SIGNIFICANT RIDGING
   BEFORE TURING SEWD INTO THE MIDDLE MO VALLEY BY EARLY EVENING. IN
   THE WAKE OF THIS FEATURE IT APPEARS WEAK RIDGING OVER ERN MT WILL
   TEMPORARILY SUPPRESS CONVECTION...BUT AID BOUNDARY LAYER HEATING
   ACROSS THE PLAINS.  IN SPITE OF WEAK SUBSIDENCE...IT APPEARS NEAR
   DRY ADIABATIC LAPSE RATES AND FORCING OVER THE HIGHER TERRAIN SHOULD
   AID AT LEAST ISOLATED THUNDERSTORM DEVELOPMENT WITHIN SUFFICIENT
   DEEP LAYER SHEAR TO SUPPORT STORM ROTATION AND POSSIBLE SUPERCELLS.
   
   OF MORE CONCERN IS THE STRONG SHORTWAVE TROUGH THAT WILL MOVE ACROSS
   WA/ORE EARLY IN THE PERIOD AND APPROACH WRN MT AROUND 00Z.  LARGE
   SCALE ASCENT AND MASS FIELDS SUGGEST THIS UPSTREAM FEATURE WILL AID
   CONVECTIVE DEVELOPMENT ACROSS THE NRN ROCKIES WITH EWD
   MOVEMENT/ORGANIZATION POSSIBLE INTO WRN MT DURING THE EVENING HOURS.
    GIVEN THE VERTICAL SHEAR AND MOIST ELY BOUNDARY LAYER COMPONENT
   ACROSS MT...IT APPEARS THIS ACTIVITY MAY VERY WELL PROPAGATE ACROSS
   MUCH OF WRN/CNTRL MT BY 12Z.  ALTHOUGH 00Z MODELS DO NOT DEPICT
   SIGNIFICANT INSTABILITY ACROSS THIS REGION...VERY COOL MID LEVEL
   THERMAL TROUGH...H5 TEMPS FROM MINUS 14-18 WILL SPREAD ACROSS SFC
   DEW POINTS IN THE UPPER 40S-LOWER 50S...YIELDING SUFFICIENT CAPE FOR
   ROBUST CONVECTION.  LARGE HAIL MAY ACCOMPANY EARLY ACTIVITY WHILE
   DAMAGING WINDS COULD EVOLVE OVER THE PLAINS WITH ANY ORGANIZED
   MCS-TYPE EPISODE DURING THE NIGHT.  OTHERWISE...ISOLATED STORMS
   ACROSS THE ERN PLAINS MAY PRODUCE GUSTY WINDS OR PERHAPS LARGE HAIL
   DURING THE LATE AFTERNOON/EVENING HOURS.
