SPOT FORECAST FOR WILSON PEAK
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
826 AM MST MON NOV 30 2009

.DISCUSSION...THE COMBINATION OF A RIDGE OF HIGH PRESSURE OVER THE
NORTHERN GREAT BASIN AND A LOW OVER NORTHERN MEXICO WILL CAUSE
WINDS ALOFT TO BE EASTERLY TODAY. A SUBSIDENCE INVERSION HAS
FORMED OVER THE PAST 24 HRS WHICH IS LOCATED NEAR 10000 FT MSL. THIS
WILL BE THE TOP OF THE MIXING LAYER AND WHILE THE TRANSPORT WINDS
UNDER THIS INVERSION WILL BE EAST AT 10-15 KT FOR GOOD HORIZONTAL
DISPERSION THERE WILL BE A CAP FOR VERTICAL DISPERSION CAUSING
POOR CLEARING INDICES FOR TODAY. THE RIDGE ALOFT WILL BACK OFF THE
COAST TUESDAY ALLOWING A COLD FRONT TO SLIP DOWN FROM THE NORTH
ACROSS YOUR AREA TUESDAY AFTERNOON FOR MUCH BETTER CLEARING INDICES.
