NATIONAL WEATHER SERVICE SALT LAKE CITY UT
623 PM MST SUN NOV 18 2012

.DISCUSSION...HIGH PRESSURE ALOFT WILL STRENGTHEN ACROSS THE
DESERT SOUTHWEST THROUGH THE FIRST HALF OF THE WEEK. THIS WILL
ALLOW FOR A LIGHT SOUTHWESTERLY FLOW ALOFT ACROSS THE BURN
AREA THROUGH AT LEAST TUESDAY. HOWEVER...AN INVERSION JUST
ABOVE THE RIDGETOPS WILL GREATLY LIMIT MIXING AND TRANSPORT
WINDS KEEPING CLEARING INDICES BELOW 500.

THE FLOW ALOFT IS EXPECTED TO INCREASE WEDNESDAY...AND ALTHOUGH
THE INVERSION WILL LIKELY REMAIN IN PLACE...ITS POSSIBLE
TRANSPORT WINDS WILL BECOME SUFFICIENTLY STRONG TO PUSH CLEARING
INDICES ABOVE 500 FOR THE AFTERNOON HOURS.

A DRY COLD FRONT IS FORECAST TO CROSS THE AREA WEDNESDAY NIGHT
WITH STABLE HIGH PRESSURE FOLLOWING FOR THE LATTER HALF OF THE
WEEK.
