.DISCUSSION...

A RIDGE OF HIGH PRESSURE WILL CONTINUE TO INFLUENCE WEATHER OVER
THE FIRE TODAY WITH DRY CONDITIONS. THE AXIS OF THE RIDGE WILL
HAVE MOVED INTO EASTERN WYOMING BY NOON TODAY WITH SOUTHWEST FLOW
BUILDING OVER THE FIRE. WIND SHIFTS WILL MAINLY IMPACT THE UPPER
LEVEL WIND AROUND THE FIRE BASED ON THE CONTINUED SOUTHEAST WIND
YESTERDAY. AN APPROACHING WAVE OF LOW PRESSURE WILL HELP TO
INCREASE CLOUD COVER OVER THE BURN SITE TONIGHT...AND PRODUCE SOME
ISOLATED TO WIDELY SCATTERED SHOWERS. A MIX OF RAIN AND SNOW IS
POSSIBLE DURING THE LATE EVENING HOURS...WITH SNOW BECOMING
PREVAILING BY THE EARLY MORNING HOURS. ADDITIONALLY...THIS SYSTEM
WILL CONTINUE GUSTY WIND...WITH STRONG GUSTS EXPECTED ACROSS THE
FIRE. THE STRONGEST WIND GUSTS EXPECTED FOR MUCH OF THE FORECAST
PERIOD. THIS WILL RESULT IN MUCH COOLER TEMPERATURES ACROSS THE
FIRE FOR SUNDAY.

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