NATIONAL WEATHER SERVICE SALT LAKE CITY UT
724 AM MDT SUN MAY 6 2012

.DISCUSSION...RIDGE OF HIGH PRESSURE BUILDING IN OVER THE NORTHERN
GREAT BASIN WILL KEEP A DRY COOL FLOW OVER THE REGION TODAY. THE
TRANSPORT WINDS ARE VERY LIGHT AND COMBINE THAT WITH A SUBSIDENCE
INVERSION BELOW 12000 FEET MSL AND THE NET RESULT IS POOR MIXING
TODAY AND THEREFORE A LOW CLEARING INDEX. A DEVELOPING LOW
PRESSURE SYSTEM OVER ARIZONA ON MONDAY IS EXPECTED TO INCREASE THE
TRANSPORT WINDS AS WELL AS DESTABILIZE THE AIR MASS TO SOME DEGREE...
BUT THIS WILL NOT OCCUR UNTIL AFTER 1200-1400 MDT MONDAY AFTERNOON.
