AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
255 PM MST SUN JAN 22 2006

.SYNOPSIS...HIGH PRESSURE WILL BUILD ACROSS THE AREA THROUGH
TUESDAY. THIS HIGH IS EXPECTED TO WEAKEN DURING THE MIDDLE OF THE
WEEK...ALLOWING A SERIES OF PACIFIC STORM SYSTEMS TO IMPACT THE AREA
FRIDAY THROUGH THE UPCOMING WEEKEND.

&&

.DISCUSSION...SURFACE HIGH IS SITUATED OVER THE WEST DESERTS AND
INTO IDAHO. LOW LEVEL CLOUDS HAVE ERODED MOST AREAS AND SKIES ARE
CLEAR BUT SHALLOW MOISTURE HAS DEVELOPED SMALL AREAS OF CUMULUS IN
THE WEST CENTRAL DESERTS. SHALLOW MOISTURE AND INSTABILITY UNDER THE
INVERSION NEAR 700 MB HAVE POPPED WEAK ISOLATED SNOW SHOWERS AND
CUMULUS ALONG THE SALT LAKE UPPER BENCHES THIS AFTERNOON WHERE
SURFACE TO LOW LEVEL NORTHWEST FLOW IS AIDING CONVERGENCE. BANDS OF
HIGH CLOUDS WILL SPILL OVER THE MEAN RIDGE TO OUR WEST AND AFFECT
NORTHERN UTAH TONIGHT BUT OVERALL GOOD RADIATIONAL COOLING WILL
DOMINATE. AREAS OF FOG AND STRATUS SHOULD FORM AGAIN IN THE DESERTS
AND VALLEYS WHERE DEEPER SNOW AND MODERATE DEW POINT DEPRESSIONS
WILL RESULT IN VERY COLD TEMPERATURES. IN FAR SOUTHWEST UTAH EARLIER
WINDS WERE LOCALLY STRONG AND WITH A TIGHT SURFACE GRADIENT PUSHING
SOUTH BUT REMAINING BETWEEN LAS VEGAS AND ST. GEORGE THERE WILL BE
LOCALLY STRONG NORTHEAST WINDS AGAIN TONIGHT. WILL ISSUE WIND
ADVISORY FOR THESE FAVORED GAP AREAS OF SOUTHWEST UTAH THOUGH COLD
AIR ADVECTION IS CONFINED TO A SMALL AREA AND SUBSIDENCE INVERSION
LOWERS WITH TIME.

WARMING ALOFT WILL OCCUR MONDAY AND TUESDAY. THIS WILL AGGRAVATE
VALLEYS AREAS WITH INCREASING HAZE AND FOG. INVERSION LOWERS TO NEAR
6000 FT MSL BY TUESDAY. UPPER LOW THAT WILL FORM OVER THE SOUTHWEST
STATES...DUE TO ENERGY NOW DIVING INTO SOUTHERN CALIFORNIA...IS
PROGGED TO LIFT ACROSS THE 4-CORNERS REGION. BOTH GFS AND NAM RUNS
SUPPORTED BY UKMET AND ECMWF WHICH WOULD BRING SYNOPTIC LIFT ON THE
NORTHEAST SIDE OF THE SYSTEM. THIS WOULD SPREAD CLOUDS INTO SOUTHERN
UTAH AND PRECIPITATION ON WEDNESDAY. SNOW LEVELS COULD BE QUITE LOW
WITH THIS SYSTEM GIVEN TIMING AND COOLING AIR MASS. PRECIPITATION
WOULD LINGER INTO THE EVENING AND THEN END AS THE SYSTEM EJECTS
THROUGH COLORADO. SOUTHWEST FLOW IN ITS WAKE WILL BRING GRADUALLY
COOLING ALOFT OVER NORTHERN UTAH THURSDAY WITH INCREASING CLOUDS
THURSDAY NIGHT.

NEXT PACIFIC SYSTEM STILL ON TRACK FOR FRIDAY. COLD ENOUGH FOR SNOW
IN THE VALLEYS WITH ONLY BRIEF INCREASED MIXING AHEAD OF IT. THE
UPPER TROUGH AXIS IS PROGGED SPLIT SOMEWHAT AND DIP ACROSS
SOUTHERN UTAH ON SATURDAY. THIS WILL KEEP SNOW SHOWERS THROUGH THE
DAY AND INTO EARLY EVENING...SUCH AS I-15 CORRIDOR. 12Z MODEL SUITE
DEPICTING A STRONGER UPPER TROUGH DUE TO ARRIVE BY SUNDAY. THESE
SYSTEMS WOULD BRING SIGNIFICANT MOUNTAIN SNOW FOR WESTERLY FACING
AREAS AND A COUPLE PERIODS OF VALLEY SNOWFALL.
