SPOT FORECAST FOR RESERVATION RIDGE
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
830 AM MST MON JAN 9 2012

.DISCUSSION...HIGH PRESSURE WILL BUILD OVERHEAD TODAY...RESULTING IN
POOR MIXING AND LOW CLEARING INDICES. WINDS WILL BE MAINLY TERRAIN
DRIVEN TODAY. TRANSPORT WINDS WILL INCREASE TOMORROW AHEAD OF AN
APPROACHING DRY COLD FRONT EXPECTED TO CROSS THE AREA WEDNESDAY
MORNING. ALTHOUGH CLEARING INDEX FORECASTED FOR TOMORROW IS 400...IT
IS POSSIBLE THAT MIXING TOMORROW WILL BE SUFFICIENT TO WARRANT A
CLEARING INDEX ABOVE 500. MIXING WILL IMPROVE WEDNESDAY BEHIND THE
COLD FRONT. BEYOND WEDNESDAY...THERE IS DISAGREEMENT BETWEEN THE
WEATHER MODELS WHETHER HIGH PRESSURE WILL RETURN...SO IT IS HARD TO
SAY WITH ANY CERTAINTY WHAT WILL HAPPEN WITH MIXING BEYOND
WEDNESDAY.
