SPOT FORECAST FOR UPPER SANTA CLARA PILES
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
245 PM MST MON JAN 14 2013

.DISCUSSION...STRONG UPPER LEVEL RIDGE WILL BUILD INTO THE GREAT
BASIN FOR THE REMAINDER OF THE WEEK.  THIS WILL RESULT IN STRONG
INVERSIONS SETTING UP NEARLY ALL WESTERN VALLEY LOCATIONS WHICH WILL
YIELD LIMITED MIXING DEPTHS. THIS WILL RESULT IN LOW CLEARING
INDICES IN MANY LOCATIONS...INCLUDING THE UPPER SANTA CLARA PILES.
THE BREEZY NORTH WINDS ON TUESDAY WILL PROVIDE DECENT TRANSPORT
WINDS BUT IT IS ANTICIPATED THAT MIXING WILL BE TOO SHALLOW TO
ACHIEVE A HIGH CLEARING INDEX. AS WARMER AIR MOVES IN ALOFT...HIGHER
ELEVATIONS MAY BEGIN TO MIX TO GREATER DEPTHS DURING THE MIDDLE AND
LATTER PORTION OF THE WEEK. THEREFORE...THE BURN LOCATION MAY BEGIN
TO SEE BETTER MIXING LATER THIS WEEK.
