AREAS AFFECTED...WRN MT/ERN ID

CONCERNING...SEVERE THUNDERSTORM POTENTIAL 

VALID 052028Z - 052200Z

TRENDS ARE BEING MONITORED FOR INCREASING SEVERE THREAT AND
POSSIBILITY OF A WW.

DESTABILIZATION IS ONGOING ALONG/AHEAD OF COLD FRONT ADVANCING
ACROSS THE NORTHERN INTERMOUNTAIN REGION INTO THE NORTHERN ROCKIES. 
CONVECTION ALREADY APPEARS TO BE INCREASING FROM THE MOUNTAINS OF
WESTERN MONTANA THROUGH EASTERN IDAHO...WHERE FORCING FOR UPWARD
VERTICAL MOTION WILL STRENGTHEN AHEAD OF APPROACHING VIGOROUS UPPER
TROUGH BETWEEN NOW AND 23Z.  WITH SHEAR ALSO STRENGTHENING LATE THIS
AFTERNOON AS EXIT REGION OF MID/HIGH-LEVEL JET OVERSPREADS
REGION...STEEP LAPSE RATES WITH CAPE LOCALLY AS HIGH AS 1000 J/KG
MAY SUPPORT ISOLATED SEVERE STORMS WITH HAIL/DAMAGING WIND GUSTS.

BEST SEVERE POTENTIAL APPEARS TO EXIST IN THE IMMEDIATE LEE OF THE
MONTANA ROCKIES...NEAR/WEST OF GREAT FALLS...WHERE LOW-LEVEL
MOISTURE IS A BIT BETTER...AND EASTERLY UPSLOPE FLOW WILL ENHANCE
SHEAR PROFILES AND POTENTIAL FOR SUPERCELLS.
