AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
844 PM MST FRI JAN 22 2010

.SYNOPSIS...A LARGE AND POTENT PACIFIC STORM WILL CONTINUE TO
IMPACT THE REGION THROUGH SUNDAY. HIGH PRESSURE WILL BRIEFLY
RETURN MONDAY...BEFORE A SPLITTING STORM SYSTEM MOVES THROUGH THE
REGION TUESDAY.

&&

.DISCUSSION...LONGWAVE TROUGH ENCOMPASSES MUCH OF THE WESTERN
CONUS THIS EVENING BASED ON EVENING WV IMAGERY AND OBJECTIVE
ANALYSIS. MAJORITY OF SYNOPTIC SCALE FORCING HAS LIFTED NORTHEAST
INTO THE HIGH PLAINS OF EASTERN MT...WHILE BROAD MID LEVEL COLD
POOL RESIDES ACROSS THE INTERMOUNTAIN WEST. SUBTLE 700MB WAVE
CURRENTLY MOVING THROUGH NORTHERN UT THIS EVENING...BUT WITH
UNSTABLE PROFILES IS YIELDING A NICE RESPONSE WITH FAIRLY
WIDESPREAD SNOW SHOWERS ACROSS MUCH OF THE WASATCH FRONT. OF
PARTICULAR CONCERN IS ORGANIZED MESOSCALE BAND WHICH HAS DEVELOPED
ACROSS THE SOUTHERN WASATCH FRONT. 00Z NAM PICKS UP ON THIS
FEATURE FAIRLY WELL AND MAINTAINS IT THROUGH THE EVENING HOURS
BEFORE DISSIPATING IT AFTER 06Z. GIVEN ORGANIZED APPEARANCE ON
88-D IMAGERY AND WEB-CAMS SHOWING FAIRLY QUICK ACCUMULATIONS
ACROSS UTAH COUNTY...HAVE GONE AHEAD AND ISSUED A WINTER WX
ADVISORY THROUGH 4AM. MAY NEED TO EXTEND GOING WINTER STORM
WARNING FOR WASATCH MOUNTAIN VALLEYS THROUGH THE NIGHT AS WELL AS
THIS BAND CONTINUES TO SPREAD ACROSS THE HEBER VALLEY.

THE OTHER IMMEDIATE CONCERN TONIGHT IS 700MB TROUGH LIFTING INTO
SOUTHWEST UT INDUCING BANDED SNOWFALL ACROSS THIS AREA. THUS FAR
THIS BAND HAS BEEN FAIRLY TRANSITORY AND THUS AM NOT ANTICIPATING
HEAVY ACCUMULATIONS...HOWEVER IF THIS BAND DOES BECOME STATIONARY
WILL LIKELY NEED TO ISSUE AN ADVISORY FOR ZONE 16 AS WELL AS
EXTEND THE GOING WARNING FOR THE SOUTHERN MOUNTAINS. OTHERWISE
ANTICIPATE BEING ABLE TO LET WARNINGS FOR THE CENTRAL
MOUNTAINS/BOOK CLIFFS EXPIRE AS SCHEDULED AT 11PM.

FLOW ALOFT FORECAST TO GRADUALLY BECOME NORTHWEST LATE TONIGHT
THROUGH SATURDAY AS UPPER LOW BECOMES SOLIDIFIED ACROSS THE
NORTHERN PLAINS AND MID LEVEL RIDGE AMPLIFIES ALONG THE PACIFIC
COAST. 500MB TEMPS FORECAST TO REMAIN AROUND -28C THROUGHOUT THE
DAY RESULTING IN FAIRLY STEEP LAPSE RATES ACROSS THE FORECAST
AREA. HOWEVER BOTH THE 00Z GFS AND NAM SPREAD DRIER AIR INTO
NORTHERN UT WHILE MOISTURE AND ASSOCIATED ISENTROPIC ASCENT
WRAPPING AROUND NORTHERN PLAINS LOW REMAIN NORTH AND EAST OF THE
AREA. ALTHOUGH ANTICIPATE CONVECTION TO DEVELOP ACROSS THE HIGHER
TERRAIN OF NORTHERN UT DURING THE DAY GIVEN FAIRLY STEEP LAPSE
RATES...AM QUITE CONCERNED DRIER AIR AND SHORTER DURATION OF
CONVECTIVE SNOWFALL MAY GREATLY LIMIT ADDITIONAL SNOWFALL TOTALS
ACROSS THE HIGHER TERRAIN. WILL LIKELY TRIM BACK SNOWFALL AMOUNTS
SATURDAY ACROSS THE COTTONWOODS WITH WSW UPDATE LATER ON.

&&

.AVIATION...THE MAIN OPERATIONAL CONCERN AT THE SLC TERMINAL THROUGH
MIDNIGHT WILL BE THE TIMING OF PASSING SNOW SHOWERS. AS THESE SNOW
SHOWERS PASS THE TERMINAL...BRIEF PERIODS OF MVFR OR HIGH END IFR
CONDITIONS ARE POSSIBLE. OTHERWISE...EXPECT VFR CONDITIONS TO
PREVAIL FOR THE REMAINDER OF THE OVERNIGHT HOURS.

&&

.SLC WATCHES/WARNINGS/ADVISORIES...
