A SURGE OF MOISTURE ACROSS NORTHWESTERN WYOMING WILL KEEP CLOUD
COVER OVER THE BURN SITE THROUGH THE DAY. WHILE THE MAIN AREAS OF
SHOWER ACTIVITY ARE EXPECTED TO BE NORTH AND WEST OF THE BURN
SITE... THE POTENTIAL FOR A COUPLE SHOWERS DOES EXIST. WHILE SHOWERS
WILL BE PREDOMINATELY SNOWFALL THIS MORNING...EXPECT THE POTENTIAL
FOR MIXED PRECIPITATION DURING THE AFTERNOON HOURS BEFORE
CONVERTING BACK TO SNOW OVERNIGHT. WIND OVER THE AREA SHOULD BE
RELATIVELY LIGHT...THOUGH WITH THE ONGOING PRECIPITATION THE BURN
SITE MAY EXPERIENCE PERIODS OF GUSTY NORTHWEST WIND THIS
AFTERNOON. SHOWER ACTIVITY SHOULD THEN END LATE THIS EVENING WITH
DRY CONDITIONS EXPECTED THROUGH THE MIDDLE PORTION OF THE WEEK.
