AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
455 AM MDT WED APR 5 2006

.SYNOPSIS...UPPER LEVEL TROUGH OVER THE WEST COAST STATES EARLY THIS
MORNING WILL MOVES THROUGH UTAH LATER TODAY. THE TROUGH WILL EXIT
UTAH EARLY THURSDAY...AND WILL BE FOLLOWED BY HIGH PRESSURE ALOFT
FOR THE END OF THE WEEK.

&&

.DISCUSSION...THE COLD CORE UPPER TROUGH HAS MOVED INTO CA OVERNIGHT.
DEEP LAYER MOISTURE HAS SPREAD NORTH AHEAD OF THIS TROUGH THROUGH
NV/WRN ID...WITH SOME OF THIS MOISTURE SPILLING OVER INTO WRN UT.
HEAVY PRECIP A BIT SLOW TO START OVER SW UT...BUT SHOULD DEVELOP
RAPIDLY THIS MORNING AS THE TROUGH CONTINUES TO MOVE STEADILY TO THE
EAST. CONVECTION A GOOD BET ALONG THE SURFACE FRONT...WHICH WILL MOVE
INTO WRN UT SHORTLY. THE STRONGEST CONVECTION LIKELY TO REMAIN ALONG
THE FRONT OVER SRN UT IN VICINITY OF THE BEST JET SUPPORT.

THE REMAINDER OF THE STATE WILL GET INTO THE ACTION LATER TODAY AS
THE FRONT PRESSES EAST-NE ACROSS THE STATE. HEAVY PRECIP WILL
DEVELOP OVER THE NRN MOUNTAINS LATE TODAY/TONIGHT AS THE CORE OF THE
UPPER TROUGH SETTLES OVER THE STATE. A MOIST/UNSTABLE AIRMASS OVER
THE NORTH COMBINED WITH FAVORABLE OROGRAPHICS SHOULD GENERATE HEAVY
PRECIP ALONG THE WASATCH RANGE AND THE ADJACENT VALLEYS TO THE WEST.
HEAVY SNOWFALL A GOOD BET ALONG THE WEST FACING SLOPES INTO AT LEAST
EARLY THURSDAY.

INSTABILITY SHOWERS LIKELY TO CONTINUE INTO THURSDAY AFTERNOON...THEN
STRONG RIDGING SHOULD BRING AN END TO PRECIP EARLY THURSDAY NIGHT.
THE RIDGE WILL CENTER OVER UTAH FRIDAY...THEN GET NUDGED OFF TO THE
EAST AS THE NEXT PACIFIC TROUGH SETTLES IN ALONG 130W. THIS NEXT
TROUGH LOOKS TO REMAIN ALONG OR JUST OFF THE COAST THROUGH AT LEAST
SUNDAY. THE ECMWF MODEL AS BEEN CONSISTENT IN HOLDING THIS FEATURE
NEAR 130W...WITH A SERIES OF WEAK DISTURBANCES EJECTING OUT OF THE
TROUGH THROUGH THE NRN GREAT BASIN/NRN ROCKIES. THE GFS MODEL
BOUNCES BETWEEN THE ECMWF SOLUTION...AND A SOLUTION WHERE A
SPLITTING AND WEAKENING TROUGH MOVES INLAND LATE IN THE WEEKEND. FOR
NOW WILL GO WITH THE MORE CONSISTENT ECMWF MODEL WHICH WOULD BRING
AT BEST A CHANCE OF SHOWERS TO THE NORTH WITH EACH PASSING SHORTWAVE.

&&

.HYDRO...HEAVY PRECIP DEVELOPING THIS MORNING OVER THE EXTREME SW
ZONES MAY NOT PRODUCE THE LONG DURATION PRECIP EARLIER ANTICIPATED...
BUT INSTEAD COULD PRODUCE HEAVY SHORT-DURATION PRECIP TODAY. STILL
LOOKING FOR SIGNIFICANT RISES IN THE RIVERS/STREAMS FROM THIS
PRECIP...WITH ANY RESULTANT FLOODING MINOR AT BEST. THE SANTA CLARA
RIVER NEAR GUNLOCK STILL LOOKS TO BE THE AREA OF MOST CONCERN TODAY.

&&

.AVIATION...A 30 PERCENT CHANCE OF RAIN SHOWERS THIS MORNING WILL
INCREASE TO 80 PERCENT BY MIDDAY AS A COLD FRONT APPROACHES KSLC.
THIS COLD FRONT WILL MOVE IN FROM SOUTHWEST TO NORTHEAST AND WILL
RESULT IN VERY GUSTY SOUTH TO SOUTHWEST WINDS WITH SPEEDS REACHING 35
KNOTS OR MORE AS IT PASSES AROUND MIDDAY. THERE IS A THREAT OF
LIGHTNING AND LOCALLY HEAVY RAIN SHOWERS LATE THIS MORNING THROUGH
THIS AFTERNOON.
