AREAS AFFECTED...NE WY...WRN SD...FAR SE MT...FAR SW ND

CONCERNING...SEVERE THUNDERSTORM POTENTIAL 

VALID 272353Z - 280200Z

A THREAT FOR LARGE HAIL AND WIND DAMAGE WILL BE LIKELY WITH
SUPERCELLS THAT INITIATE AND TRACK NEWD ACROSS THE REGION OVER THE
NEXT FEW HOURS. AN ISOLATED TORNADO THREAT MAY ALSO DEVELOP. A WW
MAY BE CONSIDERED FOR WRN SD AND NE WY IF STORMS CONTINUE TO
INCREASE IN COVERAGE.

SFC ANALYSIS CURRENTLY SHOWS A SFC LOW ACROSS CNTRL WY WITH A
FRONTAL BOUNDARY EXTENDING NEWD ACROSS NRN WY AND WRN SD. SFC
DEWPOINTS ALONG THE BOUNDARY RANGE FROM THE MID 40S F IN NCNTRL WY
TO THE UPPER 50S F ACROSS WRN SD. AS A RESULT...MODERATE INSTABILITY
IS IN PLACE WHICH SHOULD SUSTAIN THE DEVELOPING STORMS THIS EVENING.
OBJECTIVE ANALYSIS CURRENTLY SHOWS 0-6 KM SHEAR VALUES ALONG THE
BOUNDARY IN THE 45 TO 55 KT RANGE WITH VERY STEEP LAPSE RATES
SUGGESTING SUPERCELLS WITH LARGE HAIL WILL BE LIKELY. ALTHOUGH LCL
HEIGHTS ARE RELATIVELY HIGH ACROSS THE REGION...STRONG DIRECTIONAL
SHEAR PROFILES ALSO SUGGEST AN ISOLATED TORNADO/WIND DAMAGE THREAT
MAY EXIST WITH THE STRONGEST SUPERCELLS EARLY THIS EVENING.
