SPOT FORECAST FOR DUCK CREEK
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
653 AM MST SAT NOV 21 2009

.DISCUSSION...A COLD FRONT CURRENTLY MOVING THROUGH NORTHERN UTAH WILL
CONTINUE TO APPROACH THE DUCK CREEK SITE THIS MORNING. AS A
RESUL...SOUTHWEST WINDS ARE EXPECTED TO RAPIDLY INCREASE BETWEEN 8
AM AND 10 AM AND REMAIN GUSTY THROUGH MIDDAY. LOOK FOR WINDS TO
TURN WESTERLY WITH FRONTAL PASSAGE IN THE 11 AM TO 1 PM
WINDOW...WITH WEST TO NORTHWEST WINDS REMAINING GUSTY IN NATURE
THROUGH MID AFTERNOON BEFORE TAPERING. THE WIND SHIFT AND A
SLIGHT INCREASE IN MID LEVEL CLOUDS SHOULD BE THE ONLY
SIGNIFICANT FIRE WEATHER CONCERNS WITH FRONTAL PASSAGE...AS
MOISTURE REMAINS EXTREMELY LIMITED. NO ISSUES WITH CLEARING
INDICES THROUGH SUNDAY...LOOKS LIKE GOOD ENOUGH MIXING POTENTIAL
FOR ELEVATED CLEARING INDICES THROUGH THAT TIME.
