...THERE IS A SLGT RISK OF SVR TSTMS ACROSS PORTIONS OF MT...

...MT...

BOUNDARY LAYER INSTABILITY HAS YET TO BE OVERTURNED ACROSS THE
PLAINS OF MT DESPITE THE WIDESPREAD ONGOING CONVECTION.  00Z
SOUNDING FROM GGW SUPPORTS THIS WITH VERY STEEP LAPSE RATES THROUGH
500MB...ROUGHLY 9C/KM. STRENGTH OF UPPER TROUGH AND ASSOCIATED
SPEED MAX WILL CONTINUE TO ENHANCE LARGE SCALE ASCENT ACROSS MT THIS
EVENING.  THIS WILL UNDOUBTEDLY CONTRIBUTE TO THE ONGOING CONVECTIVE
THREAT...AT LEAST UNTIL THE INSTABILITY IS DEPLETED BY ONGOING
ACTIVITY.  GIVEN THE VERY DEEP BOUNDARY LAYER AND SIGNIFICANT DEEP
LAYER SHEAR...STRONG WINDS SHOULD BE THE PRIMARY SEVERE
THREAT...ESPECIALLY WITH ANY BOW SHAPED STRUCTURES THAT ORIENT
THEMSELVES PERPENDICULAR...NW-SE...TO THE MEAN WIND.
