SPOT FORECAST FOR ADAMS HEAD
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
147 PM MST THU NOV 19 2009

.DISCUSSION...CONTINUED DRY AND STABLE HIGH PRESSURE OVER THE
BURN SITE TONIGHT...RESULTING IN POOR MIXING UNDER MOSTLY CLEAR
SKIES. POOR MIXING IS DUE TO LIGHT TRANSPORT WINDS UNDER THE
STABLE AIRMASS. THE RIDGE WILL SHIFT EAST TOMORROW AHEAD OF AN
APPROACHING STORM SYSTEM...ALLOWING SOUTHERLY TRANSPORT WINDS TO
RAPIDLY INCREASE AND MIXING TO IMPROVE ACCORDINGLY. WINDS ON THE
EAST SLOPES WILL BE LOWER THAN ON WEST SLOPES...ALTHOUGH A MARKED
INCREASE IS STILL ANTICIPATED. THE NEXT TWO SYSTEMS EXPECTED
SATURDAY AND AGAIN SUNDAY WILL AFFECT MAINLY NORTHERN UTAH. A WEAK
DRY COLD FRONT WILL MOVE THROUGH THROUGH THE BURN SITE LATER
SATURDAY AFTERNOON. PRECIPITATION CHANCES WILL REMAIN EXTREMELY
SMALL OVER THE SOUTH WITH BOTH STORMS.
