...THERE IS A SLGT RISK OF SVR TSTMS ACROSS PORTIONS OF THE HIGH
PLAINS...

...HIGH PLAINS...

STRONG/ISOLATED SEVERE CONVECTION HAS FOR THE MOST PART MOVED OFF
THE HIGHER TERRAIN AS WARM ADVECTION REGIME SLOWLY INTENSIFIES FROM
ERN CO...INTO CENTRAL SD.  00Z SOUNDINGS FROM THIS REGION SUGGEST
THUNDERSTORM ACTIVITY SHOULD MOVE SHARPLY SWD ALONG NARROW
INSTABILITY AXIS WHERE SBCAPE VALUES ARE ROUGHLY 1000 J/KG.  OVER
THE LAST FEW HOURS...AN EXPANDING CLUSTER OF THUNDERSTORMS FROM
ECNTRL WY...SWRN SD...WRN NEB APPEARS TO BE AIDING SWD SURGE TO SFC
BOUNDARY THAT SHOULD MOVE INTO NERN CO BY 04Z. ADDITIONAL
CONVECTION MAY DEVELOP ALONG THIS BOUNDARY AS IT PROGRESSES INTO YET
TO BE OVERTURNED AIRMASS.  HOWEVER...WITH LOSS OF DAYTIME
HEATING...WEAKENING LAPSE RATES AND MARGINAL INSTABILITY SHOULD
RESULT IN A LESS THAN FAVORABLE ENVIRONMENT FOR ORGANIZED SEVERE
THUNDERSTORMS. UNTIL THEN...ISOLATED LARGE HAIL OR PERHAPS A SEVERE
WIND GUST WILL ACCOMPANY THE STRONGEST STORMS AS THEY PROPAGATE SWD.
