VALID 030207Z - 030300Z

WW MAY BE REQUIRED FOR PORTIONS OF SERN MT/EXTREME NERN WY INTO NWRN
SD AND EXTREME SWRN ND BY 03Z.

REGIONAL RADARS SHOW A CLUSTER OF STORMS EXTENDING FROM PETROLEUM
COUNTY SEWD TO BIG HORN COUNTY.  THE SRN EXTENT OF THESE STORMS HAS
BEGUN TO TURN MORE EWD AS THIS ACTIVITY TOPS THE UPPER RIDGE. 
INCREASING ELY LOW-LEVEL WINDS DOWNSTREAM OF THIS ACTIVITY SHOULD
MAINTAIN A MOIST AIR MASS AND COMBINED WITH STEEP LAPSE RATES WILL
RESULT IN MODERATE INSTABILITY.  STRONG DEEP LAYER SHEAR WILL
CONTINUE TO FAVOR STORM ORGANIZATION WITH THE POTENTIAL FOR A
FORWARD PROPAGATING LINEAR MCS TOWARD NWRN SD/SWRN ND.

ONGOING THUNDERSTORMS WILL BE MONITORED OVER THE NEXT HOUR TO
DIAGNOSE SEVERE POTENTIAL.
