AREAS AFFECTED...N-CNTRL INTO NERN MT

CONCERNING...SEVERE THUNDERSTORM POTENTIAL 

VALID 062037Z - 062200Z

POTENTIAL FOR A FEW SEVERE STORMS APPEARS TO BE INCREASING AND AREA
IS BEING MONITORED FOR A POSSIBLE WW ISSUANCE.

VISIBLE SATELLITE IMAGERY SHOWS A DEEPENING CUMULUS FIELD FROM
AROUND GTF EWD THROUGH LWT WITHIN A DEEPLY-MIXED BOUNDARY LAYER.
INSPECTION OF WATER VAPOR IMAGERY SUGGESTS THAT THIS AREA IS ON THE
LEADING EDGE OF HEIGHT FALLS ASSOCIATED WITH SHORTWAVE TROUGH AND
MID-LEVEL SPEED MAX SHIFTING EWD THROUGH WA AND BRITISH COLUMBIA.
WHILE LOCAL AIR MASS IS NOT PARTICULARLY UNSTABLE...PRESENCE OF
STEEP LOW/MID-LEVEL LAPSE RATES AND INCREASING VERTICAL SHEAR DO
SUGGEST THE POTENTIAL FOR A FEW SEVERE STORMS LATER THIS AFTERNOON
INTO THIS EVENING. 

ANY STORMS THAT DO DEVELOP SHOULD BE HIGH-BASED WITH THE POTENTIAL
FOR LARGE HAIL AND DAMAGING DOWNBURSTS.
