.DISCUSSION...DRY AND STABLE HIGH PRESSURE WILL REMAIN OVER THE
BURN SITE THE REST OF TODAY...RESULTING IN POOR MIXING UNDER SUNNY
SKIES. THE POOR MIXING IS DUE TO LIGHT TRANSPORT WINDS AND
INCREASING VALLEY INVERSIONS. THE RIDGE WILL SHIFT EAST TOMORROW
AHEAD OF AN APPROACHING STORM SYSTEM...ALLOWING SOUTHERLY
TRANSPORT WINDS TO RAPIDLY INCREASE AND MIXING TO IMPROVE
ACCORDINGLY. THE SYSTEM WILL AFFECT MAINLY NORTHERN UTAH ON
SATURDAY...BUT WILL BRING A COLD FRONT THROUGH THE BURN SITE LATER
SATURDAY AFTERNOON. ANOTHER STORM SYSTEM WILL BRUSH MANLY FAR
