AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
348 PM MST SAT DEC 20 2008

.SYNOPSIS...A SERIES OF PACIFIC STORMS WILL IMPACT THE AREA DURING THE
NEXT SEVEN DAYS.

&&

.DISCUSSION...WATER VAPOR LOOP SHOWS AN UPPER LOW TRAVERSING THE
UPPER MIDWEST. THE NEXT SYSTEM OF INTEREST IS AN UPPER LOW NEAR
150W/50N WHICH HAS TELECONNECTIONS WELL TO ITS SOUTHWEST INTO A
TROPICAL AIRMASS. ACARS 400-250MB WIND OBSERVATIONS SHOWS A
POSITIVELY TILTED UPPER LEVEL TROUGH OVERHEAD...WITH 100-140KT OF
NORTHWESTERLY FLOW FROM THE PACIFIC NORTHWEST TOWARD THE GREAT
BASIN. 12Z 700MB ANALYSIS PLACED THE CYCLONE NEAR NORTH
DAKOTA...WITH THE CORE OF THE -27C AIR OVER MONTANA. LOCALLY...WARM
ADVECTION WAS INITIATING WITH -19C AT SLC AND -17C UPSTREAM AT KLKN.

12Z KSLC RAOB INDICATES ABOUT 10C OF COLD ADVECTION DURING THE PAST
24 HOURS BETWEEN 575-750MB. 3 TO 5C OF WARM ADVECTION WAS NOTED
BETWEEN 400-500MB. WESTERLY FLOW WAS OBSERVED IN THE LOWER
LEVELS...WITH STRONG NORTHWESTERLY FLOW ALOFT.

WESTERLY FLOW OVER THE 3-4C LAKE IS PROVIDING LAKE ENHANCED SNOWFALL
ALONG THE NORTHERN WASATCH FRONT AND WESTERN WASATCH MOUNTAINS NORTH
OF INTERSTATE 80. AS THE FLOW ALOFT VEERS AND WARMS...THE BAND HAS
BECOME BETTER ORGANIZED DURING THE EARLY AFTERNOON AND IS DRIFTING
BACK SOUTH. 12Z NAM BUFKIT PROFILES SUGGEST WARMING ALOFT WILL
DIMINISH THE LAKE INDUCED EQUILIBRIUM LEVELS LATE THIS AFTERNOON AND
EVENING...EFFECTIVELY SHUTTING OFF THE LAKE ENHANCEMENT PROCESS.
HAVE THEREFORE CANCELLED THE WARNINGS ACROSS THE NORTH WITH THE
STORM WINDING DOWN.

NEXT SYSTEM IS CURRENTLY NEAR THE GULF OF ALASKA. BLENDED TOTAL
PRECIPITABLE WATER PRODUCT INDICATES THIS SYSTEM HAS TELECONNECTIONS
INTO A TROPICAL AIRMASS NEAR HAWAII WITH PRECIPITABLE WATER VALUES
NEAR 2 INCHES. GIVEN THE MOISTURE AVAILABILITY AND AMOUNT OF WARM
ADVECTION THAT OCCURS INTO THE EARLY WORK WEEK...NEXT SYSTEM SHOULD
BRING PLENTY OF QPF TO THE REGION. WITH TEMPERATURES AHEAD OF THE
SYSTEM WARMING HOWEVER...MANY VALLEYS WILL MIX WITH RAIN FOR MUCH OF
THE EVENT. NAM BUFKIT PROFILES INDICATE LOGAN AND OGDEN MAY REMAIN
COLD ENOUGH FOR ALMOST ALL SNOW DURING THE EVENT. SOUTHWEST FACING
MOUNTAINS WILL INITIALLY HAVE THE BEST SNOW EARLY ON DURING THE
EVENT...WITH NORTHWESTERLY FLOW DEVELOPING MONDAY NIGHT AND TUESDAY.
LIGHT SNOW SHOULD BEGIN SUNDAY AFTERNOON IN THE HIGHER
TERRAIN...WITH ACCUMULATIONS BECOMING MORE LIKELY SUNDAY NIGHT.

WITH WARMING TEMPERATURES AND APPROACHING DYNAMICS...HAVE TO
CONSIDER POTENTIAL FOR SNOWMELT AND ADDITIONAL RAIN ACROSS SOUTHWEST
UTAH. ST GEORGE WEB CAM SHOWS MUCH IF NOT ALL OF THE RECENT SNOWS
HAVE ALREADY MELTED. VISIBLE SATELLITE LOOP ALSO SUGGESTS A SLOW
MELT OCCURRING TODAY ACROSS LOWER ELEVATIONS OF SOUTHWEST UTAH. WILL
HAVE TO CONTINUE TO MONITOR SNOWMELT AND APPROACHING LOW ELEVATION
RAINFALL...CONSIDERING AMOUNT OF SNOW WATER EQUIVALENT BELOW 7KFT
(ABOUT 3 INCHES).

EXPECT A BRIEF BREAK DURING MIDWEEK...BEFORE THE NEXT SYSTEM DEEPENS
A WEST COAST TROUGH LATE DURING THE WORK WEEK.

&&

.AVIATION...VFR CONDITIONS WITH CLOUDS BELOW 6000 FT AGL ARE
EXPECTED TO PREVAIL THIS EVENING AT THE SLC TERMINAL. THERE IS A 30
PERCENT CHANCE OF OCCASIONAL CEILINGS AROUND 4000 TO 5000 FT AGL AND
SNOW SHOWERS AFFECTING THE TERMINAL BETWEEN 00Z AND 03Z...WHICH
WOULD BRING CONDITIONS DOWN TO HIGH-END IFR OR LOW-END MVFR.
SOUTHEAST WINDS SHOULD REMAIN AT THE TERMINAL WITH A 30 PERCENT
CHANCE OF NORTHWEST WINDS BETWEEN 23Z AND 03Z AS SHOWERS DRIFT BY TO
THE NORTH OF THE AIRFIELD.

&&

.SLC WATCHES/WARNINGS/ADVISORIES...
UT...WINTER STORM WATCH FROM 10 PM SUNDAY TO 4 PM TUESDAY FOR UTZ006-
     UTZ007-UTZ008-UTZ009.

     WINTER STORM WATCH FROM 10 PM SUNDAY TO 10 PM MONDAY FOR UTZ001-
