   ...THERE IS A SLGT RISK OF SVR TSTMS OVER PARTS OF THE NORTHERN AND
   CENTRAL PLAINS STATES ON TUESDAY...
   
   CORRECTED FOR GRAPHICS ERROR
   
   ...NORTHERN PLAINS...
   LARGE UPPER TROUGH WILL CONTINUE TO DIG INTO THE ROCKIES ON
   TUESDAY...WITH BAND OF STRONG MID LEVEL WINDS EXTENDING FROM CO INTO
   MN.  MAIN SURFACE BAROCLINIC ZONE WILL ALSO LIE IN THIS
   AXIS...PROVIDING A FOCUS FOR SEVERE THUNDERSTORM DEVELOPMENT. 
   AIRMASS ALONG AND SOUTH OF FRONT WILL BE MOIST AND VERY UNSTABLE
   WITH STEEP LAPSE RATES AND AFTERNOON MLCAPE VALUES OVER 2500 J/KG. 
   PRESENT INDICATIONS ARE THAT SCATTERED THUNDERSTORMS WILL DEVELOP BY
   LATE AFTERNOON FROM NORTHWEST NEB INTO EASTERN ND AND NORTHWEST MN. 
   THIS ACTIVITY WILL BECOME MORE NUMEROUS THROUGH THE EVENING AS
   SECONDARY COLD FRONT SURGES INTO AREA FROM THE NORTHWEST.  FORECAST
   SOUNDINGS IN THIS REGION SHOW SUFFICIENT VERTICAL SHEAR PROFILES FOR
   SUPERCELLS CAPABLE OF VERY LARGE HAIL AND DAMAGING WINDS.  STORMS
   WILL LIKELY ORGANIZE INTO ONE OR MORE MCSS AND TRACK NORTHEASTWARD
   ACROSS PARTS OF NEB/SD/MN OVERNIGHT.
   
   ...CENTRAL HIGH PLAINS...
   STRONG SOUTHERLY LOW LEVEL WINDS WILL PERSIST OVER THE
   CENTRAL/SOUTHERN HIGH PLAINS ON TUESDAY...HELPING TO MAINTAIN AT
   LEAST LOW 60S DEWPOINTS OVER THE EASTERN TX PANHANDLE INTO WESTERN
   KS.  FULL SUNSHINE AND STEEP LAPSE RATES WILL CONTRIBUTE TO THE
   DEVELOPMENT OF A VERY UNSTABLE AIRMASS ALONG THE DRYLINE WITH
   AFTERNOON MLCAPE VALUES OF 2500+ J/KG. SCATTERED THUNDERSTORMS WILL
   LIKELY DEVELOP ALONG DRYLINE FROM THE TX PANHANDLE NORTHWARD ACROSS
   WESTERN KS INTO SOUTHWEST NEB. COMBINATION OF HIGH INSTABILITY AND
   SUFFICIENT VERTICAL SHEAR WILL RESULT IN ISOLATED SUPERCELLS CAPABLE
   OF LARGE HAIL.
