.DISCUSSION...

WARM AND MAINLY DRY CONDITIONS WILL PERSIST OVER THE NEXT COUPLE DAYS
ACROSS THE WILDFIRE AREA. SLIGHTLY HIGHER RH...COOLER TEMPERATURES...ALONG
WITH WEAKER WINDS ARE EXPECTED TODAY. HOWEVER...LOCAL RED FLAG CONDITIONS
COULD STILL OCCUR ACROSS PORTIONS OF THE SOUTHERN ABSAROKA MOUNTAINS
INCLUDING AREAS AFFECTED BY THE NORTON POINT WILDFIRE. A DISTURBANCE MOVING
ACROSS THE AREA SUNDAY AND SUNDAY NIGHT WILL GIVE THE AREA THE BEST
CHANCE OF SEEING SOME RAIN THROUGH NEXT THURSDAY. HOWEVER...THIS CHANCE
OF RAIN...ESPECIALLY SEEING A WETTING RAIN REMAINS VERY SLIM.

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