AREAS AFFECTED...SERN MT INTO N-CNTRL WY

CONCERNING...SEVERE THUNDERSTORM POTENTIAL 

VALID 102145Z - 102315Z

STRONGEST STORMS WILL BE CAPABLE OF LARGE HAIL AND ISOLATED
TORNADOES. WW MAY BE REQUIRED.

TSTMS HAVE INCREASED IN COVERAGE AND INTENSITY OVER THE PAST HALF
HOUR FROM SHERIDAN COUNTY WY NEWD INTO CUSTER/ROSEBUD COUNTIES IN
SERN MT. COMBINATION OF STRONGLY DIVERGENT UPPER-LEVEL FLOW AND
ENHANCED LOW-LEVEL CONVERGENCE N/NE OF SURFACE LOW LOCATED NEAR SHR
AS OF 21Z ARE LIKELY PROMOTING STRONG...DEEP-LAYER ASCENT ACROSS THE
REGION.

1000-1500 J/KG MLCAPES COUPLED WITH 40-50KTS OF 0-6KM SHEAR WILL
SUPPORT ORGANIZED TSTMS...INCLUDING SUPERCELLS. THOUGH LARGE HAIL
WILL LIKELY BE THE PRIMARY SEVERE WEATHER THREAT /GIVEN THE
FAVORABLY LOW WBZ HEIGHTS OF 5-7KFT/...BACKED NATURE OF LOW-LEVEL
WINDS WILL ENHANCE LOW-LEVEL SHEAR/ISOLATED TORNADO POTENTIAL.
