AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
950 AM MST WED DEC 28 2005

.SYNOPSIS...A RIDGE OVER THE AREA WILL MOVE EAST TODAY. MOISTURE FROM
THE NEXT PACIFIC STORM WILL SPREAD ACROSS EXTREME NORTHERN UTAH
TODAY. THIS NEXT STORM WILL SEND A COLD FRONT THROUGH THE AREA
TONIGHT WITH A COLD MOIST NORTHWEST FLOW CONTINUING THURSDAY.

&&

.DISCUSSION...PACIFIC TROUGH NOW WALLOPING THE CALIFORNIA COAST WITH
SHORT WAVE RIDGING ACROSS THE GREAT BASIN THIS MORNING. WEAK WARM
AIR ADVECTION CONTINUES ACROSS EXTREME NORTHERN UTAH WITH THE REST
OF THE FORECAST AREA IN THE WARM SECTOR. SOME WEAK LIFT ASSOCIATED
WITH WARM AIR ADVECTION WILL GENERATE LIGHT PRECIP ALONG THE
UTAH-IDAHO BORDER TODAY OTHERWISE DRY AND MILD CONDITIONS WILL
PREVAIL TODAY. SOUTHERLY BREEZES WILL DEVELOP IN MOST AREAS TODAY
RESULTING IN A WELL MIXED AIRMASS AND AFTER A MILD MORNING THE
AFTERNOON TEMPERATURES SHOULD RESPOND NICELY EVEN WITH EXTENSIVE
CLOUD COVER. NO UPDATES PLANNED FOR THE SHORT TERM.

THE 12Z NAM BRINGS MUCH COLDER AIR ALOFT...-28 AT 500 MB...ACROSS
THE FORECAST AREA TONIGHT WITH THE INCOMING TROUGH. THIS IN LINE
WITH THE LATEST UKMET RUN WITH THE LATEST EC LEANING THERE AS WELL.
THIS SOLUTION WOULD GIVE MOST OF THE FORECAST AREA AT LEAST SOME
SHOT OF PRECIPITATION WITH SOME GENEROUS AMOUNTS OVER THE NORTHERN
HALF OF UTAH. THE LATEST NAM IS AT ODDS WITH THE 00Z AND 06Z GFS
WHICH MOVED THE COLD AIR ALOFT ACROSS IDAHO...JUST GRAZING NORTHERN
UTAH. CONSIDERING CURRENT SATELLITE DATA AND ANALYSIS...THINK THAT
THE LATEST NAM/UKMET HAVE THE BETTER IDEA. WILL LOOK CLOSELY AT THE
12Z GFS...BUT PROBABLY WILL NEED TO BEEF UP POPS OVER SOUTHERN AND
CENTRAL UTAH TONIGHT AS WELL AS HIGHER QPF AND INCREASED SNOW
AMOUNTS FOR THE MOUNTAINS.

BRENCHLEY

&&

.AVIATION...EXPECT CEILINGS TO REMAIN ABOVE 7 KFT THROUGH AT LEAST
23Z. WINDS WILL REMAIN SOUTHERLY AND INCREASE DURING THE AFTERNOON
HOURS...POSSIBLY GUSTING ABOVE 20 KTS AT TIMES AFTER 22Z. SURFACE
FRONT/WIND SHIFT EXPECTED TO REACH KSLC AROUND 03-04Z. BEHIND THIS
FRONT...EXPECT CEILINGS TO FALL INTO MVFR RANGE WITH PERIODS OF
LIGHT RAIN THROUGH 09Z. PREDOMINANT VFR CONDITIONS EXPECTED AFTER
09Z.
