NATIONAL WEATHER SERVICE SALT LAKE CITY UT
930 PM MST SAT FEB 4 2012

.SYNOPSIS...A WEAK UPPER LOW WILL REMAIN OVER UTAH THROUGH THE
WEEKEND THEN SHIFT EAST MONDAY. HIGH PRESSURE WILL RETURN FOR
TUESDAY.

&&

.DISCUSSION...THE LARGE-SCALE PATTERN ACROSS THE INTERIOR WEST FOR
TONIGHT THROUGH TOMORROW CONSISTS OF A BLOCKING PATTERN WITH A LARGE
CUTOFF LOW CENTERED OVER UTAH UNDERNEATH A DOME OF HIGH PRESSURE TO
THE NORTH. THE LOW OVER UTAH WILL KEEP OCCASIONAL CLOUDS OVER THE
AREA BUT OTHERWISE MOISTURE AND LIFT REMAINS RATHER LOW TO PRODUCE
MUCH OF ANYTHING IN THE WAY OF PRECIPITATION.

A MEAN EASTERLY FLOW COULD CONTINUE TO BRING SOME ENHANCED CANYON
WINDS TO PORTIONS OF THE WASATCH FRONT OVERNIGHT AND INTO THE
MORNING HOURS...BUT THESE WINDS WILL NOT BE AS STRONG AS THE
PREVIOUS TWO DAYS.

RELATIVELY BENIGN WEATHER CAN BE EXPECTED THROUGH THE END OF THE
WEEK. THE CUTOFF LOW IS PROGGED TO BECOME ABSORBED INTO THE MEAN
WESTERLIES ON MONDAY AS A TROUGH SLIDES ACROSS MONTANA AND CONTINUES
INTO THE GREAT PLAINS. MEANWHILE...A TROUGH APPROACHING FROM THE
PACIFIC WILL SPLIT OVER THE WEST COAST ON TUESDAY AS IT TRIES TO
BREAK THROUGH THE MEAN RIDGE. HIGH PRESSURE IS EXPECTED TO THEN
RE-BUILD OVER THE WEST COAST BEHIND IT...GRADUALLY SHIFTING EAST
INTO THE GREAT BASIN TOWARDS THE END OF THE WEEK.

WILL UPDATE TO REMOVE POPS AND ADJUST SKY COVER FOR THE REMAINDER OF
THE NIGHT...AND TO LOWER TEMPERATURES AT A FEW SITES MAINLY ACROSS
THE HIGH TERRAIN.

&&

.AVIATION...SURFACE WINDS AT THE SLC TERMINAL WILL BE LIGHT
SOUTHEAST THROUGH ABOUT 18Z SUNDAY THEN SWITCH TO THE NORTHWEST. VFR
CONDITIONS WILL PREVAIL UNDER MOSTLY CLEAR SKIES.
