840 AM MDT FRI MAY 28 2010

.DISCUSSION...STRONG UPPER LEVEL WINDS ARE MUCH LIKE
YESTERDAY...ALTHOUGH A BIT STRONGER. AS A RESULT...EXPECT THAT SOUTH
WINDS AT THE BURN SITE WILL BE STRONGER THAN YESTERDAY...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.

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.
