.DISCUSSION...
A LINE OF THUNDERSTORMS IS EXPECTED TO DEVELOP OVER THE BIG HORN
MOUNTAINS THIS AFTERNOON AND MOVE OUT THROUGH THE FIRE AREA EARLY
THIS EVENING. ISOLATED WETTING RAINS ARE POSSIBLE WITH THESE STORMS
BUT WITH SLIGHTLY DRIER AIR MOVING IN FROM THE SOUTHWEST AND THE
FAST MOVEMENT EXPECTED WITH THE STORMS...WETTING RAIN ON THE FIRE
IS NOT LIKELY. THE DRY AIR FROM THE SOUTHWEST WILL DECREASE THE
CHANCES FOR THUNDERSTORM COVERAGE WEDNESDAY AFTERNOON. A SLIGHT
CHANCE FOR HIGH BASED THUNDERSTORMS IS EXPECTED WEDNESDAY
AFTERNOON.
