822 AM MDT FRI MAY 28 2010

.DISCUSSION...STRONG UPPER LEVEL WINDS ARE MUCH LIKE
YESTERDAY...ALTHOUGH A BIT STRONGER. AS A RESULT...EXPECT THAT THE
BURN SITE WILL SEE GUSTY SOUTH WINDS...ESPECIALLY AS MIXING IMPROVES
THIS AFTERNOON AND THE STRONG UPPER LEVEL WINDS ARE ABLE TO MIX DOWN
TO LOWER ELEVATIONS. GUST IN EXCESS OF 50 MPH ARE POSSIBLE THIS
AFTERNOON...ESPECIALLY ACROSS THE HIGHER TERRAIN. HOWEVER...IT
APPEARS AS THOUGH THE BURN SITE IS A BIT SHELTERED FROM THE
SOUTHWEST...WHICH WILL PROTECT THE AREA A BIT FROM THESE STRONG
WINDS. HOWEVER...WITH SUCH STRONG WINDS ALOFT...BE PREPARED FOR
STRONG GUSTS.

A COLD FRONT WILL CROSS THE BURN AREA OVERNIGHT...RELAXING AND
SHIFTING THE WINDS TO THE NORTHWEST AROUND MIDNIGHT. WINDS WILL BE
SIGNIFICANTLY LIGHTER TOMORROW...BUT SUFFICIENT FOR GOOD CLEARING
INDICES.
