...THERE IS A SLGT RISK OF SVR TSTMS OVER PARTS OF THE NORTHERN AND
CENTRAL PLAINS STATES ON TUESDAY...

...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.
