.DISCUSSION...

A WEAK DISTURBANCE MOVING ACROSS NORTHERN WYOMING WILL RESULT IN
CONSIDERABLE MID AND HIGH LEVEL CLOUDINESS FROM ABOUT 9 AM TO 3
PM...BUT DECREASING CLOUDINESS IS EXPECTED MID TO LATE THIS
AFTERNOON. OTHERWISE...A DRY AND COOLER DAY WILL OCCUR WITH MAINLY
LIGHT AND TERRAIN DRIVEN WINDS.

ON FRIDAY...EXPECT WARMER AND MUCH LOWER HUMIDITY WITH BREEZY
SOUTH TO SOUTHWEST WINDS.

ON SATURDAY...A COLD FRONT WILL PUSH ACROSS THE FIRE SITE EARLY
SATURDAY WITH WINDS SWITCHING TO THE NORTH. THERE IS A GOOD CHANCE
FOR A WETTING PRECIPITATION EVENT IN THE SATURDAY AFTERNOON AND
SATURDAY NIGHT TIME FRAME. RAIN IS EXPECTED TO CHANGE TO SNOW SATURDAY
AFTERNOON...WITH SOME SNOW ACCUMULATION POSSIBLE AT THE FIRE SITE.
THE SNOW IS EXPECTED TO COME TO AN END SUNDAY...BUT A COOL AND
MOIST DAY WILL BE OBSERVED.
