AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
232 PM MDT TUE APR 17 2007

.SYNOPSIS...A STRONG COLD FRONT WILL CROSS UTAH LATE TONIGHT AND
WEDNESDAY. THE NEXT IN SERIES OF PACIFIC STORMS WILL AFFECT THE
GREAT BASIN FRIDAY INTO SATURDAY.

&&

.DISCUSSION...VALLEY SNOW EVENT IN THE CARDS WITH INCOMING COLD
FRONT AND CONSOLIDATED UPPER LOW. COLD PACIFIC SYSTEM MOVING INTO
THE PACIFIC NORTHWEST AND IDAHO WITH INCREASING SOUTHWEST FLOW AHEAD
OF IT. RESIDUAL MOISTURE AND WEAK INSTABILITY HAS DEVELOPED
CUMULUS TODAY ACROSS THE NORTHERN HALF UTAH MOUNTAINS WITH ONLY
ISOLATED CONVECTION IN THE EASTERN UINTAS FAVORING WESTERLY FLOW.
SCATTERED CONVECTION WILL DEVELOP THIS EVENING ACROSS NORTHERN
UTAH WITH SOME CELLS ADVECTING FROM NORTHEAST NEVADA AND ACROSS
NORTHWEST UTAH. HAVE ADDED WEATHER DOWN TO ABOUT I-80 AND WASATCH
PLATEAU TO UINTAS THIS EVENING FOR ISOLATED CONVECTION MOVING
ACROSS THE STATE IN THE DESTABILIZATION ALOFT WITH MARGINAL
MOISTURE. HAVE ISSUED WIND ADVISORY FOR DEVELOPING SOUTHERLY
GRADIENT AND 50 KNOTS AT 700 MB MOVING INTO WESTERN UTAH LATER
THIS EVENING. SURFACE FRONT ON TRACK TO CROSS NORTHWEST UTAH JUST
AFTER MIDNIGHT AND THEN SWEEP ACROSS THE GSL THROUGH 12Z
WEDNESDAY. FAST MOVING CELLS WILL CONTINUE AFTER MIDNIGHT FROM THE
NORTHWEST DESERTS ACROSS THE FAR NORTH IN REGION OF GOOD UPWARD
MOTION. MID LEVEL BAROCLINIC ZONE WILL BE JUST BEHIND THIS FRONT WITH
INCREASING PVA AND COLD AIR ADVECTION ALOFT WORKING TO ENHANCE THE
BOUNDARY WEDNESDAY MORNING.

MAIN VORT MAX DIVES INTO SOUTHWEST UTAH WEDNESDAY MORNING AND PUSHES
THE COLD FRONT THROUGH THAT REGION. ENOUGH LIFT ALONG THIS FRONT WILL
TRIGGER A NARROW BAND OF CONVECTION FROM SOUTHWEST UTAH IN THE
MORNING AND THEN REACHING THE EASTERN VALLEYS BY AFTERNOON. HAVE
INCLUDED WIND ADVISORY FOR SOUTHWEST AND EASTERN VALLEYS WHICH
WILL BE IN A WELL MIXED DRY AND PARTLY SUNNY PREFRONTAL
ENVIRONMENT. POST FRONTAL WEST WINDS WILL ALSO AFFECT PARTS OF
NORTHWEST AND NORTH CENTRAL UTAH INTO THE AFTERNOON SPREADING INTO
THE UINTAH BASIN. AN ABRUPT CHANGE ALONG THE MID LEVEL FRONTAL BAND
FROM RAIN TO SNOW IN NORTHERN UTAH DOWN TO THE VALLEY
FLOORS...THEN THE BANDS EXITS BY EARLY AFTERNOON WITH PARTIAL
CLEARING. COLD POOL ALOFT PROGGED TO TAKE A DIRECT PATH ACROSS
NORTHERN UTAH SO AIR MASS WILL DESTABILIZE AGAIN WITH SNOW SHOWERS
DEVELOPING...AND ANOTHER ORGANIZED AREA OF SNOW SHOWERS JUST AHEAD
OF THE COLD CORE. JUST WARM ENOUGH FOR RAIN SNOW MIX DOWN TO
VALLEY FLOOR BEFORE 6 PM. NOT MUCH ACCUMULATION FOR THE VALLEYS ON
WEDNESDAY BUT POSSIBLE A BRIEF BURST FOR THE BENCHES AS -9C 700
MB AIR ARRIVES JUST BEHIND THE FRONTAL PRECIP BAND. UPSLOPE
SOUTHWEST FLOW HOWEVER WILL ENHANCE SNOWFALL AS THE BAND HITS THE
WASATCH RANGE IN THIS COMMON COLD FRONTAL SCENARIO.

MAIN SNOW EVENT FORECAST TO UNFOLD WEDNESDAY EVENING WITH
THE COLD POOL CROSSING NORTHERN UTAH AND AN UNSTABLE AIR MASS
FORCED INTO THE WASATCH FRONT. 18Z NAM-WRF CONTINUES THE HIGHER
QPF TRENDS SINCE 00Z RUNS...CLOSE TO NMM-WRF...TARGETING FARMINGTON
PEAK AND NORTHERN WASATCH RANGE THROUGH 00Z...SHIFTING SOUTH INTO
COTTTONWOODS AND I-80 FOR WED EVENING. IN ADDITION LAKE ENHANCEMENT
EXPECTED AS -12C 700 MB AIR AND DEEP STEEP LAPSE RATES CROSS THE
50 TO 55F WATER. WESTERLY FLOW PROGGED BY NAM- WRF...NMM- WRF AND
GFS FOR WEDNESDAY NIGHT WITH A SLIGHT SHIFT TO NORTHWEST. THIS
TARGETS AREAS BETWEEN OGDEN AND SLC. WE MAY NEED HEADLINES FOR
THIS SNOWFALL AT LEAST FOR BENCHES AND MOUNTAIN VALLEYS. UPSLOPE
FLOW SHOULD KEEP HEAVY SNOW SHOWERS ACROSS THE WASATCH RANGE AND
WESTERN UINTAS THROUGH WEDNESDAY NIGHT. UPPER LOW EXITS WITH
DECREASING INSTABILITY DEPTH THURSDAY MORNING TO END SNOW SHOWERS.
FLOW BACKS AND WARM AIR ADVECTION DEVELOPS QUICKLY BY THURSDAY
AFTERNOON.

NEXT SYSTEM DUE FOR FRIDAY AND INTO SATURDAY BUT FORECAST TREND
TAKES THE BRUNT OF THIS ELONGATED UPPER TROUGH TOWARD SOUTHERN
UTAH AGAIN. GOOD GFS ENSEMBLE MEMBER AGREEMENT OF THIS SPLIT FLOW.
THIS WOULD BRING A FEW SHOWERS TO NORTHERN UTAH WITH THE UPPER
TROUGH AXIS ON SATURDAY BUT A BREAK SATURDAY NIGHT INTO SUNDAY.
HAVE ADJUSTED GRIDS FOR HIGHER CHANCES IN SOUTHERN UTAH PER LATEST
MODELS INCLUDING ECMWF AND LOWER IN THE FAR NORTHERN VALLEYS TO
BREAK OUT THE WEEKEND WEATHER. YET ANOTHER SYSTEM DIGGING INTO THE
GREAT BASIN RETURNS SOUTHWEST FLOW ON SUNDAY AND REDEVELOPS
SHOWERS LATER IN THE DAY. THIS SYSTEM FORECAST BY 12Z GFS...UKMET AND
ECMWF TO CLOSE OFF OVER FAR SOUTHERN UTAH BY EARLY MONDAY. THIS
SIMILAR TO THE GFS ENSEMBLE MEAN. HAVE ALSO ADJUSTED THIS IN THE
GRIDS.

&&

.AVIATION...THERE IS STILL A 20 PERCENT CHANCE THAT A NORTHWESTERLY
LAKE BREEZE COULD DEVELOP AT THE SLC TERMINAL THROUGH 00Z.
OTHERWISE...EXPECT SOUTH WINDS TO INCREASE TONIGHT AHEAD OF AN
APPROACHING STORM SYSTEM. THERE IS A 20 PERCENT CHANCE OF SHOWERS
AND THUNDERSTORMS IMPACTING THE SLC TERMINAL THIS EVENING AND
OVERNIGHT. ANY SHOWERS THAT DEVELOP WILL BRING CEILINGS TO 6000FT
AGL OR LOWER.

&&
