NATIONAL WEATHER SERVICE SALT LAKE CITY UT
1054 AM MST SUN NOV 25 2012

.DISCUSSION...A WEAK TROUGH MOVING ACROSS NORTHERN UTAH TODAY WILL
ACTUALLY BRUSH ACROSS SOUTHERN UTAH CAUSING THE TRANSPORT WINDS TO
SHIFT FROM WEST TO NORTHWEST BY TONIGHT. A SUBSIDENCE INVERSION
WILL FORM NEAR 11,000 FEET MSL FOR MONDAY CAUSING THE CLEARING
INDEX TO BE POOR. BY TUESDAY THE RIDGE IS DIRECTLY OVERHEAD IN THE
MORNING BUT WILL BE SHIFTING EAST BY AFTERNOON. ALTHOUGH THE
TRANSPORT WINDS WILL PICK UP TO 15 TO 20 MPH BY AFTERNOON...THE
SUBSIDENCE INVERSION WILL STILL BE PRESENT AT ABOUT 11,500 FEET
PREVENTING GOOD VERTICAL MIXING FROM OCCURRING. AGAIN...THE
HORIZONTAL DISPERSION WILL BE GOOD TUESDAY BUT THE CLEARING INDEX
WILL NOT BE GOOD. THE WINDS INCREASE WEDNESDAY TO 25 TO 30 MPH
AHEAD OF A COLD FRONT AND THIS WILL PUSH THE CLEARING INDEX ABOVE
500. CLEARING INDEX LIKELY TO BECOME POOR BY THURSDAY.
