AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
920 PM MST SUN DEC 23 2007

.SYNOPSIS...ANOTHER PACIFIC STORM SYSTEM WILL SWEEP ACROSS UTAH
MONDAY AND MONDAY NIGHT.  THIS STORM WILL BRING A STRONG COLD FRONT
THROUGH THE STATE WITH LOCALLY HEAVY SNOW POSSIBLE ACROSS THE
NORTHERN PORTION OF THE STATE. A POTENTIALLY STRONGER STORM IS
EXPECTED TO IMPACT THE STATE WEDNESDAY AND WEDNESDAY NIGHT.  COLD
TEMPERATURES ARE EXPECTED TO REMAIN IN PLACE THROUGH THE WEEK.

&&

.DISCUSSION...INTERESTING EVENT BEGINNING TO UNFOLD FOR NORTHERN
UTAH.  SURFACE HIGH PRESSURE REMAINS IN PLACE ACROSS UTAH THIS
EVENING AS A COLD FRONT MOVES THROUGH THE PACIFIC NORTHWEST. MID
LEVEL WARM ADVECTION UNDERWAY THIS EVENING SPREADING MID LEVEL
CLOUDS AND VIRGA INTO THE NORTHWEST PORTION OF THE STATE. DECENT
ISENTROPIC UPGLIDE PROGGED ACROSS SOUTHERN IDAHO AND FAR NORTHERN
UTAH THROUGH THE NIGHT ON THE 295K SURFACE. ALREADY SOME LIGHT SNOW
FALLING IN THIS WARM ADVECTION AREA ACROSS SOUTHERN IDAHO.  WITH THE
CONTINUED WARM ADVECTION OVERNIGHT WILL INCREASE POPS JUST A BIT FAR
NORTHERN ZONE 5...THE CACHE VALLEY...AND NORTHERN ZONE 7.  WILL ALSO
GO WITH MOSTLY CLOUDY WORDING ACROSS NORTHERN UTAH OVERNIGHT AS
CLOUD COVER SHOULD BE PRETTY WIDESPREAD.

ACROSS SOUTHERN UTAH TEMPERATURES ARE HOLDING UP MUCH BETTER AT
CEDAR CITY AND BRYCE CANYON COMPARED TO THE RAPID DROP OFF YESTERDAY
EVENING. WITH TIGHTENING SURFACE PRESSURE GRADIENT BELIEVE THAT
WINDS WILL HELP KEEP TEMPERATURES UP A BIT TONIGHT AND THIS IS WELL
HANDLED IN CURRENT GRIDS.

00Z NAM APPEARED TO INITIALIZE QUITE WELL THIS EVENING. IT CONTINUES
TO SHOW A STRONG COLD FRONT MOVING THROUGH THE CENTRAL WASATCH FRONT
AROUND MIDDAY ON MONDAY.  THERE SHOULD BE A PRETTY VIGOROUS BAND OF
PRECIPITATION ASSOCIATED WITH THE FRONT AS IT MOVES THROUGH NORTHERN
UTAH MONDAY MORNING AND AFTERNOON.  HOWEVER...THE NAM REMAINS THE
OUTLIER WITH RESPECT TO HOW FAR SOUTH THE 500 MB COLD POOL DIPS INTO
NORTHERN UTAH. THIS COULD HAVE A SIGNIFICANT IMPACT ON HOW THE EVENT
UNFOLDS.  THE NAM KEEPS THE COLD POOL FURTHER NORTH THAN THE GFS AND
ECMWF WHICH LIMITS THE DEPTH OF THE POST-FRONTAL INSTABILITY. AT
THIS TIME IT LOOKS LIKE THERE WILL BE A SOLID BAND OF PRECIPITATION
WITH THE FRONT BUT THE BAND WILL LIKELY BE FAIRLY NARROW LIMITING
THE AMOUNT OF SNOW THAT WE WILL SEE...PARTICULARLY IN VALLEY
LOCATIONS. DEEP UNIDIRECTIONAL NORTHWEST FLOW SETS UP IN THE
POST-FRONTAL ENVIRONMENT WHICH SHOULD KEEP THE SNOW GOING IN THE
WASATCH MOUNTAINS. THIS ALSO SETS THE STAGE FOR A POSSIBLE LAKE
EFFECT SNOW BAND INTO SALT LAKE COUNTY. THE GFS INDICATES THAT THERE
WILL BE DEEPER INSTABILITY AND ULTIMATELY A GREATER THREAT THAN
WOULD THE NAM.  GIVEN THAT THE NAM IS AN OUTLIER WITH THE COLD AIR
ALOFT WOULD LEAN TOWARD THE GFS SOLUTION AT THIS TIME.

&&

.AVIATION...CLOUDS WILL CONTINUE TO SPREAD ACROSS THE SLC TERMINAL
THIS EVENING WITH CEILINGS NEAR 6000FT AGL OR LOWER THROUGH THE
OVERNIGHT HOURS. EXPECT VFR CONDITIONS TO PREVAIL THROUGH THE NIGHT
BUT THERE IS A 10 PERCENT CHANCE OF BRIEF MVFR TO VFR CONDITIONS IN
FLURRIES/LIGHT SNOW AFTER 06Z.
