.DISCUSSION...

THE AIRMASS HAS BECOME UNSTABLE AND THUNDERSTORM DEVELOPMENT OVER
THE CANADIAN ROCKIES IS EXPECTED TO MOVE SOUTH TOWARDS THE FIRE
SITE BY EARLY EVENING. A SLIGHT CHANCE EXISTS THAT THESE WILL
DEVELOP FAR ENOUGH SOUTH TO AFFECT THE LOCAL AREA. A SECOND AREA
OF THUNDERSTORMS COULD ALSO APPROACH FROM THE SOUTH THIS EVENING
AS A WEAK DISTURBANCE MOVES THROUGH THE AREA. THESE WOULD DEVELOP
LATER IN THE EVENING BUT DIMINISH SOON AFTER MIDNIGHT. ANY
THUNDERSTORMS THAT DEVELOP WOULD BE SLOW MOVING...WET...AND
LOCALLY HEAVY RAIN WOULD BE POSSIBLE.
