AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
437 PM MST FRI DEC 12 2008

.SYNOPSIS...A STRONG AND COLD PACIFIC STORM WILL CROSS THE AREA
ON SATURDAY. A COLD AND UNSETTLED PATTERN WILL THEN PERSIST
THROUGH MUCH OF NEXT WEEK.

&&

.DISCUSSION...CLOUDS FROM THE THE WEAK SYSTEM THIS MORNING WILL
CONTINUE TO SHIFT EAST AND WILL BE MOVING OUT THIS EVENING AS HIGH
CLOUDS AHEAD OF THE NEXT WAVE SPREAD IN FROM THE NORTHWEST.

THIS NEXT SHORT WAVE MOVING INTO THE PACNW STATES REMAINS ON
TRACK TO BRING A SIGNIFICANT SNOW EVENT TO OUR FORECAST AREA
STARTING LATE TONIGHT AND LASTING INTO SUN.

THIS REMAINS QUITE AN IMPRESSIVE WAVE WITH THE ASSOCIATED SURFACE
LOW BOMBING 25 MB SINCE 12Z. IT WILL BE ACCOMPANIED A SHARP
VIGOROUS COLD FRONT AS IT MOVES THRU UT ON SAT.

AHEAD OF THIS FRONT...SOUTH WINDS SHOULD INCREASE OVERNIGHT AND
PRE-FRONTAL VALLEY RAIN AND SNOW AND MOUNTAIN SNOW IS POSSIBLE
ACROSS THE NRN MTNS AND VALLEYS N OF SLC LATE TONIGHT.

THE AIRMASS WITH THIS FRONT WILL BE COLD ENOUGH FOR SNOW TO THE
VALLEY FLOORS RIGHT WITH THE FRONT. INTENSE SNOWFALL AND STRONG
NORTH WINDS ARE EXPECTED THAT WILL RAPIDLY PLASTER ALL SURFACES
WITH SNOW AND MAKE ROADWAYS HAZARDOUS. THE FRONT WILL REACH THE
SALT LAKE AREA ABOUT MID MORNING AND MOVE THRU SOUTHWESTERN UT BY
EARLY EVENING. THE INTENSE SNOWFALL RATES WILL LIKELY LET UP A
COUPLE OF HOURS AFTER THE FRONT PASSES BUT SNOW WILL LIKELY
CONTINUE IN THE MTNS AND LOCALLY IN THE WESTERN VALLEYS THRU THE
NIGHT.

THERE IS THE POTENTIAL OF SIGNIFICANT ADDITIONAL ACCUMULATION IN THE
WASATCH MOUNTAINS OVERNIGHT IN THE POST FRONTAL NORTHWEST FLOW.
ALSO...THE GREAT SALT LAKE COULD GET INVOLVED FOR A TIME SAT EVE.

HAVE ISSUED WINTER STORM WARNINGS FOR THIS EVENT FOR ALL AREAS
THAT WERE UNDER THE WATCH...AS PRECIP WILL START TONIGHT IN THE
NORTH AND CONFIDENCE IS HIGH THAT THE SYSTEM WILL CONTINUE TO HOLD
TOGETHER AS IT MOVES THRU THE REST OF THE CWA TOMORROW. FEEL
THAT WARNINGS ARE JUSTIFIED IN THIS SITUATION EVEN IF SOME
LOCATIONS DONT QUITE REACH WARNING AMOUNTS...DUE TO THE NATURE OF
THIS STRONG FRONT AND THE EXPECTED IMPACT ON TRAVEL.

AS THIS INITIAL WAVE MOVES EAST SUN...A NEW LOW IS FORECAST TO
DEVELOP ALONG THE WA COAST THEN SWING THRU THE NRN GREAT BASIN LATER
MON THRU TUE. THIS WOULD BRING ANOTHER ROUND OF SNOW TO MUCH OF THE
FORECAST AREA...EVEN THE FAR SOUTH.

THE GFS AND EC DIVERGE AFTER MON ON WHERE THE SHORT WAVES ROTATING
THRU THE WESTERN US LONG WAVE WILL BE SO WITH THIS LOW
CONFIDENCE...HAVE NOT MADE MANY CHANGES TO THE GRIDS AFTER DAY 3.

&&

.AVIATION...NORTHERLY WINDS ARE EXPECTED TO SHIFT TO THE SOUTH
BETWEEN 00Z AND 01Z. THESE WINDS WILL GRADUALLY RAMP UP BETWEEN
02Z AND 04Z...FURTHER INCREASING OVERNIGHT AHEAD OF THE STRONG SAT
MORNING COLD FRONT APPROACHING FROM THE NW.

FOCUSING ON THE SAT MORNING COLD FRONT...FRONTAL STRUCTURE LOOKS
IDEAL FOR SIGNIFICANT IMPACT TO THE SALT LAKE TERMINAL LATE MORNING
THROUGH EARLY AFTERNOON SAT. HEAVY SNOWFALL...STRONG NW
WINDS...AND RAPID RNWY ACCUMULATIONS ARE EXPECTED WITH AND BEHIND
THE FRONT. AT THIS TIME...THINKING FRONTAL TIMING WILL BE BETWEEN
15-17Z.
