AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
930 PM MST THU DEC 18 2008

.SYNOPSIS...A COLD UPPER LOW WILL PUSH A COLD FRONT THROUGH THE
REGION FRIDAY AFTERNOON THROUGH FRIDAY NIGHT. HIGH PRESSURE WILL
BRIEFLY BUILD ACROSS THE REGION SATURDAY BEFORE THE NEXT SYSTEM
IMPACTS THE REGION EARLY NEXT WEEK.

&&

.DISCUSSION...STORM SYSTEM CURRENTLY OVER THE PACIFIC NORTHWEST WILL
DIVE SOUTH INTO UTAH TOMORROW. WEST-SOUTHWEST FLOW ALOFT WILL
INCREASE OVERNIGHT AHEAD OF THE APPROACHING STORM. IN
ADDITION...PRESSURE RISES ACROSS SOUTHEAST UTAH COUPLED WITH
PRESSURE FALLS OVER SOUTHERN IDAHO WILL SERVE TO TIGHTEN THE
PRESSURE GRADIENT ACROSS UTAH. GUSTY SOUTH WINDS HAVE ALREADY BEGUN
ACROSS THE MOUNTAINS AND WESTERN VALLEYS THIS EVENING...AND THESE
WINDS SHOULD INCREASE AS THE STORM SYSTEM APPROACHES.

OTHERWISE...CLOUDS HAVE BEEN SLOW TO MOVE INTO NORTHERN UTAH BUT
THEY WILL FILL IN OVERNIGHT. HOWEVER...TEMPERATURES HAVE ALREADY
PLUMMETED OVER SOME NORTHERN VALLEYS WHERE THE WINDS HAVE BEEN
LIGHT. TEMPERATURES IN THE CACHE VALLEY AND UINTA BASIN HAVE ALREADY
DROPPED BELOW FORECAST MINS. MEANWHILE...A PERSISTENT LAYER OF
STRATUS CLOUDS HAS DEVELOPED ACROSS SOUTHWEST UTAH AS WELL AS NEAR
PRICE. THESE CLOUDS ARE EXPECTED TO HOLD TEMPERATURES UP A BIT
TONIGHT. ALTHOUGH MOST OF THE LOWER-LEVEL MOISTURE LOOKS TO BE IN
THE FORM OF LOW STRATUS...PATCHY FOG REMAINS POSSIBLE OVER SOME
VALLEY AREAS TONIGHT.

PRECIPITATION IS EXPECTED TO DEVELOP ACROSS FAR NORTHERN UTAH
OVERNIGHT AS A JET STREAK MOVES ACROSS THE AREA. THE COLD FRONT
ASSOCIATED WITH THE STORM WILL THEN ENTER NORTHERN UTAH TOMORROW
AFTERNOON AND MOVE INTO SOUTHERN UTAH DURING THE EVENING HOURS. A
PERIOD OF INTENSE SNOWFALL WILL ACCOMPANY THE FRONT OVER NORTHERN
UTAH. WINTER WEATHER HIGHLIGHTS HAVE BEEN ISSUED FOR THE WASATCH
FRONT AND WASATCH MOUNTAINS AND SEEM FINE FOR NOW...BUT NEXT SHIFT
MAY NEED TO EVALUATE WHETHER ADVISORIES ARE NEEDED FOR AREAS SUCH AS
THE CACHE VALLEY...UINTA MOUNTAINS AND SOUTHWEST WYOMING. CONCERN
FOR THE VALLEYS IS THAT SNOW COULD IMPACT TRAVEL DURING THE EVENING
COMMUTE. AS THE FRONT PROGRESSES SOUTH...IT WILL LOSE SOME
UPPER-LEVEL SUPPORT SO SNOWFALL IS EXPECTED TO BE SUB-ADVISORY
ACROSS SOUTHERN UTAH.

VERY COLD AIR WILL SETTLE ACROSS THE AREA TOMORROW NIGHT AND
SATURDAY. STILL EXPECTING 700MB TEMPERATURES DOWN TO -20C OR LOWER
ACROSS EXTREME NORTHERN UTAH. WITH STEEP LAPSE RATES BETWEEN THE GSL
AND 700MB...EXPECT LAKE-EFFECT SNOW TO DEVELOP TOMORROW NIGHT.
HOWEVER...BUFR WIND PROFILE WOULD INDICATE ANY LAKE BANDS THAT
DEVELOP WILL IMPACT AREAS TO THE EAST OF THE GSL.

STRONG WARM ADVECTION IS PROGGED TO DEVELOP BY SUNDAY MORNING.
HOWEVER...COLD AIR WILL LIKELY BE TRAPPED IN THE LOWER VALLEYS.
PROGRESSIVE PATTERN CONTINUES AS ANOTHER STORM SYSTEM WILL IMPACT
THE AREA MONDAY AND TUESDAY.

WILL UPDATE TO TWEAK MIN TEMPERATURES...TO INCREASE SKY COVER FOR
AREAS IMPACTED BY STRATUS AND TO INCREASE WINDS FOR A FEW ZONES.

&&

.AVIATION...SOUTH WINDS ARE EXPECTED TO HOLD THROUGH COLD FRONTAL
PASSAGE FRI AFTERNOON AT THE SALT LAKE TERMINAL. SOUTH WINDS WILL
TURN GUSTY LATE NIGHT TONIGHT THROUGH FRI MORNING WITH GUSTS GREATER
THAN 25MPH EXPECTED TO DEVELOP AROUND SUNRISE FRI. INCREASING CLOUDS
ARE EXPECTED OVERNIGHT WITH CIGS BELOW 6000FT AGL EXPECTED BY
08-10Z. COLD FRONTAL PASSAGE FRI IS EXPECTED BETWEEN 20-23Z...WITH
ONSET OF IFR SNOW ACCOMPANYING THE FRONT. RUNWAY ACCUMULATIONS ARE
EXPECTED.

.SLC WATCHES/WARNINGS/ADVISORIES...

     UTZ007-UTZ008.

     WINTER STORM WATCH FROM 9 AM FRIDAY TO NOON SATURDAY FOR UTZ002-
