.DISCUSSION...

A WEAK DISTURBANCE AND ASSOCIATED COLD FRONT WILL PUSH SOUTHEAST
ACROSS THE AREA TODAY. THE FRONT IS EXPECTED TO MOVE ACROSS THE BIG
HORN BASIN AND THE BURN AREA IN THE EARLY AFTERNOON. ALTHOUGH WINDS
ARE EXPECTED TO BE BREEZY IN THE BASIN...THE BURN AREA IS SOMEWHAT
PROTECTED FROM THE BREEZY NORTHWEST AND NORTH WINDS. WIDELY
SCATTERED RAIN AND SNOW SHOWERS WILL REMAIN POSSIBLE...BUT WETTING
PRECIPITATION IS NOT EXPECTED. TEMPERATURES SHOULD BE A BIT
COOLER AND RELATIVE HUMIDITY A TAD HIGHER TODAY THAN WHAT OCCURRED
ON THE BURN SITE YESTERDAY.

VERY WARM AND DRY CONDITIONS...WITH MAINLY LIGHT TERRAIN DRIVEN
WINDS ARE EXPECTED FOR THE WEEKEND.

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