AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
240 PM MST MON DEC 26 2005

.SYNOPSIS...A MOIST PACIFIC STORM WILL IMPACT UTAH TONIGHT THEN MOVE
EAST OF THE AREA TUESDAY MORNING. HIGH PRESSURE WILL BUILD OVER UTAH
ON TUESDAY FOLLOWED BY THE NEXT SERIES OF STORMS EXPECTED TO AFFECT
THE AREA ON WEDNESDAY AND THURSDAY.

&&

.DISCUSSION...SHORT WAVE TROUGH CONTINUES ACROSS THE FORECAST AREA
LATE THIS AFTERNOON AND TONIGHT. A STRONG LINE OF CONVECTION HAS
DEVELOPED ALONG THE COLD FRONT ALONG THE NEVADA-UTAH STATELINE. THIS
WILL ADVANCE EASTWARD ACROSS WESTERN UTAH THROUGH THE LATE AFTERNOON
AND EARLY EVENING. APPEARS THAT SUPPORT FOR THESE STORMS...STRONG
UPPER LEVEL VORT MAX AND JET AND INCREASING SURFACE BASED
INSTABILITY...WILL WEAKEN AROUND SUNSET. WILL NOT BE SURPRISED IF WE
SEE A QUICK BURST OF 1-2 INCHES OF SNOW FROM THIS NARROW BAND OF
THUNDERSTORMS ALONG THE I-15 CORRIDOR FROM CEDAR CITY TO FILLMORE
OVER THE NEXT COUPLE OF HOURS. WILL HANDLE THESE THUNDERSTORMS AND
ASSOCIATED LOCALLY HEAVY RAIN AND SNOW AND WIND GUSTS WITH NOWCASTS
DURING THE REST OF THE AFTERNOON. PRECIPITATION MUCH MORE DIFFUSE
AND DISORGANIZED ALONG THE NORTHERN END OF THE FRONT ACROSS NOW
ACROSS EASTERN ELKO COUNTY WITH MUCH LESS HELP FROM THE JET. STILL
EXPECT PRECIPITATION TO FILL IN SOLIDLY ALONG THE WASATCH FRONT AS
THE COLD FRONT PASSES SLC AROUND 5 PM. TEMPERATURES WILL COOL BEHIND
THE FRONT AND SNOW LEVELS ARE EXPECTED TO DROP TO THE BENCHES
TONIGHT SO SOME LIGHT ACCUMULATION IS POSSIBLE. THE SNOWFALL RATES
IN THE MOUNTAINS HAVE ALREADY BRIEFLY SPIKED UP THIS AFTERNOON...2
INCHES PER HOUR IN THE WASATCH MOUNTAINS...WITH THE PASSING WARM
FRONT. THE SNOW WILL INCREASE AGAIN LATE THIS AFTERNOON AS THE COLD
FRONT GETS CLOSER. THEN EXPECTING A PERIOD OF HEAVY SNOWFALL BEHIND
THE FRONT DURING THE EVENING HOURS. THIS SHOULD HELP BRING MANY
NORTHERN UTAH MOUNTAIN AREAS INTO HEAVY SNOW WARNING LEVELS AND
WARNING WILL REMAIN POSTED AS IS. ONLY CONCERNS ARE FOR MOUNTAIN
AREAS SOUTH OF I-70 WHICH WILL EXPERIENCE STRONG SUBSIDENCE BEHIND
THIS AFTERNOONS CONVECTIVE BAND AND SNOWFALL AMOUNTS WILL GENERALLY
BE MUCH LIGHTER IN THESE AREAS. OTHER CONCERN IS THAT SNOW WILL
TAPER OFF QUICKER THAN PREVIOUSLY THOUGHT IN ALL AREAS TUESDAY
MORNING...BUT WILL LEAVE THIS DETAIL FOR UPCOMING SHIFTS.

SHORT WAVE RIDGING TAKES OVER TUESDAY FOLLOWED BY STRONG WARM AIR
ADVECTION AND PACIFIC MOISTURE STREAM OVER EXTREME NORTHERN UTAH
TUESDAY NIGHT. OVERRUNNING PRECIPITATION SETS UP ACROSS NORTHERN
UTAH ON WEDNESDAY...ALTHOUGH HAVE TEMPERED THE GFS POPS/QPFS FOR
THIS PERIOD AS IT TENDS TO GO OVERBOARD IN THIS PATTERN OVER
NORTHERN UTAH. THE NEXT TROUGH STILL PROGGED TO MOVE ACROSS NORTHERN
UTAH WEDNESDAY NIGHT AND THURSDAY WITH RELATIVELY GOOD MODEL
AGREEMENT. HAVE LEFT HIGH CHANCE AND LIKELY POPS FOR THIS PERIOD
OVER THE NORTH. THIS STORM STILL LOOKS COLD ENOUGH TO DROP SNOW
LEVELS TO THE VALLEY FLOORS BY THURSDAY MORNING. ANOTHER MILD
PACIFIC STORM IS POSSIBLE ON NEW YEARS EVE.

BRENCHLEY

.AVIATION...WIND SHIFT ASSOCIATED WITH A COLD FRONT NOW ENTERING
WESTERN UT...WILL PASS THROUGH SLC IN THE 00-02Z TIMEFRAME. EXPECT
CEILINGS TO REMAIN MVFR...HOWEVER BRIEF PERIODS IF IFR ARE POSSIBLE
WITH RAIN AND MIST THROUGH 06Z.
