AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
211 PM MST FRI MAR 24 2006

.SYNOPSIS...SOUTHERLY FLOW WILL INCREASE TONIGHT...AND BECOME
STRONG ON SATURDAY...AHEAD OF AN APPROACHING STORM SYSTEM. THIS
SYSTEM AND ASSOCIATED COLD FRONT WILL MOVE THROUGH THE AREA
SATURDAY NIGHT. HIGH PRESSURE WILL BUILD ACROSS THE AREA FOR EARLY
NEXT WEEK...BEFORE ANOTHER STORM SYSTEM IMPACTS THE REGION BY
MIDWEEK.

&&

.DISCUSSION...EARLY AFTERNOON WATER VAPOR IMAGERY AND UPPER AIR
ANALYSIS CONTINUE TO DEPICT BROAD LONGWAVE TROUGH ENCOMPASSING THE
GULF OF AK. LEAD SHORTWAVE TROUGH CONTINUES TO ROTATE NORTH ACROSS
THE PACIFIC NORTHWEST...WHILE SECONDARY SHORTWAVE NOTED
NEAR 40N/140W. THIS WAVE IS FORECAST BY MODELS TO EJECT FROM MEAN
LONGWAVE POSITION AND TRANSLATE THROUGH THE GREAT
BASIN/INTERMOUNTAIN WEST SATURDAY INTO SATURDAY NIGHT.
SOUTHWESTERLY FLOW ALOFT WILL BEGIN TO INCREASE TONIGHT...THEN
BECOME STRONG DURING THE DAY SATURDAY AS PRESSURE GRADIENT
TIGHTENS DOWNSTREAM FROM INCREASING HEIGHT/PRESSURE FALLS ACROSS
NV. GFS/NAM CONTINUE TO SHOW STRONG 850-700MB FRONTOGENESIS ACROSS
CENTRAL NV DURING THE DAY SATURDAY AS THERMAL GRADIENT TIGHTENS.
DOWNSTREAM 700MB FLOW ACROSS WESTERN UT PROGGED TO INCREASE INTO
THE 40-50KT RANGE. THIS SHOULD SUPPORT WIND GUSTS IN EXCESS OF
SEVERE LIMITS ACROSS MUCH OF WESTERN UT...AS WELL AS THE WASATCH
FRONT SATURDAY AFTERNOON. GIVEN STRENGTH OF AMBIENT WIND
FIELDS...THERMAL PACKING...AND STRONG UPPER LEVEL SUPPORT...SEVERE
GUSTS ALSO LIKELY TO ACCOMPANY COLD FRONT AS IT PUSHES THROUGH
NORTHERN AND CENTRAL UTAH SATURDAY EVENING. STRONG PRESSURE RISES
BEHIND FRONT WILL ALSO CONSIDERABLE POST-FRONTAL WINDS AS WELL
INTO THE OVERNIGHT HOURS. WILL GO AHEAD AND ISSUE HIGH WIND WATCH
FOR WESTERN UT INCLUDING THE WASATCH FRONT FOR SATURDAY AFTERNOON
AND EVENING.

IN ADDITION TO THE WIND THREAT...EXPECT A BAND OF HEAVY
PRECIPITATION INCLUDING EMBEDDED THUNDERSTORMS TO ACCOMPANY THE
FRONT. SNOW LEVELS MAY FALL TO THE VALLEY FLOOR FOR A TIME WITHIN
HEAVIER PRECIPITATION ASSOCIATED WITH FRONTAL ZONE. WILL LIKELY
SEE A BREAK IN PRECIPITATION BEHIND THE INITIAL FRONTAL
BAND...BEFORE MID LEVEL COLD POOL SPREADS ACROSS NORTHERN UT. THIS
SHOULD RESULT IN A SECONDARY AREA OF LIGHT TO MODERATE
PRECIPITATION...WITH SNOW LEVELS DOWN TO THE VALLEY FLOORS. EXPECT
SNOW TOTALS IN THE 6-12 INCH RANGE ACROSS THE WASATCH
RANGE...HOWEVER THIS COMBINED WITH WINDS REACHING/EXCEEDING SEVERE
CRITERIA AHEAD OF AND WITHIN FRONTAL ZONE WARRANTS ISSUANCE OF
WINTER STORM WATCH. WILL HIGHLIGHT WIND POTENTIAL AS WELL AS
WHITE-OUT CONDITIONS WITHIN FRONTAL BAND AS PRIMARY THREATS. MOST
VALLEY LOCATIONS CAN EXPECT UP TO A SLUSHY INCH OF ACCUMULATION BY
SUNDAY MORNING...WITH PERHAPS UP TO 3 INCHES ALONG THE UPPER BENCHES.
MID LEVEL COLD POOL PROGGED TO RESIDE ACROSS NORTHERN UT INTO
SUNDAY...HOWEVER MEAN MID LEVEL SUBSIDENCE MAY HINDER RESIDUAL
SHOWER ACTIVITY.

MEAN MID LEVEL RIDGE EXPECTED TO BUILD ACROSS THE REGION FOR LATE
SUNDAY THROUGH MONDAY. THIS RIDGE EXPECTED TO SHIFT EAST MONDAY
NIGHT...ALLOWING FOR STRENGTHENING SOUTHERLY FLOW ACROSS THE
FORECAST AREA TUESDAY. MEDIUM RANGE MODELS ALL INDICATE A MEAN
TROUGH ACROSS THE WESTERN CONUS FOR MIDWEEK...HOWEVER DIFFER WITH
RESPECT TO TIMING AND TRACK OF THIS FEATURE. FOR HOW HAVE RETAINED
CHANCE POPS FOR TUESDAY NIGHT INTO WEDNESDAY...WITH A DRYING TREND
FOR THURSDAY AND FRIDAY.
