.DISCUSSION...

INCREASING CLOUDINESS THIS MORNING WITH CONSIDERABLE MID AND HIGH
LEVEL CLOUDINESS THIS AFTERNOON. DESPITE THE INCREASE IN
CLOUDINESS...NO PRECIPITATION IS EXPECTED. ENOUGH WIND AND MIXING
WILL OCCUR FOR SMOKE DISPERSAL TO REACH THE FAIR CATEGORY THIS
AFTERNOON.

A STRONG STORM SYSTEM WILL IMPACT THE COWBOY STATE FRIDAY NIGHT
AND SATURDAY. THE MAIN IMPACT AT THE FIRE SITE WILL BE THE VERY
STRONG SOUTHWEST TO WEST WINDS. ALTHOUGH THE FIRE SITE COULD
RECEIVE SOME SNOWFALL SATURDAY AFTERNOON AND SATURDAY NIGHT...THE
BULK OF THE SNOWFALL WILL OCCUR FARTHER WEST IMPACTING THE WESTERN
PORTIONS OF THE ABSAROKA RANGE.

...THUNDERSTORMS IMPLY STRONG GUSTY AND ERRATIC WINDS...
...HAINES INDEX IS HIGH LEVEL HAINES BOTH DAY AND NIGHT...
