AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
951 PM MDT SAT MAY 22 2010

.SYNOPSIS...THE UPPER LEVEL TROUGH OVER NEVADA TONIGHT THROUGH
EARLY SUNDAY WILL LIFT NORTHEAST ACROSS UTAH SUNDAY NIGHT THROUGH
MONDAY MORNING. A SOMEWHAT DRIER SOUTHWESTERLY FLOW WILL DEVELOP ON
TUESDAY AND REMAINS IN PLACE THROUGH MIDWEEK.

&&

.DISCUSSION...THE UPPER TROUGH EXTENDING FROM THE NRN ROCKIES SW
THROUGH NRN CA WILL STRETCH APART LATE TONIGHT/EARLY SUNDAY...WITH
THE SRN PORTION FORMING A CLOSED LOW OVER SRN NV/SRN CA SUNDAY
MORNING. THIS CLOSED FEATURE SHOULD OPEN UP AS IT EJECTS NE
THROUGH UTAH SUNDAY NIGHT/EARLY MONDAY.

THE BEST THREAT FOR HEAVY PRECIP AHEAD OF THE TROUGH SHOULD COME
BY LATE SUNDAY EVENING DURING THE PERIOD OF STRONG DEEP LAYER COLD
ADVECTION AND GOOD DYNAMIC LIFT. THE BEST LIFT WEAKENS CONSIDERABLY
LATE SUNDAY NIGHT/EARLY MONDAY MORNING AS THE DECAYING TROUGH WORKS
INTO ERN UT/WRN COLORADO. THE 00Z NAM DOES HINT AT A SECOND WEAK
SHORTWAVE ASSOCIATED WITH A TRAILING MID-LEVEL COLD POOL ACROSS
NRN UTAH MONDAY AFTERNOON. COULD SEE ADDITIONAL CONVECTIVE PRECIP
UP NORTH THROUGH EARLY EVENING...THEN RAPID STABILIZATION OF THE
AIRMASS MONDAY NIGHT.

A SOMEWHAT DRIER SOUTHWESTERLY FLOW ALOFT WILL DEVELOP TUESDAY
AHEAD OF THE NEXT DEEP TROUGH APPROACHING THE WEST COAST. MEDIUM
RANGE GUIDANCE BY AND LARGE HOLDS THE CORE OF THIS FEATURE OFF THE
COAST THROUGH THE END OF THE WEEK. EXPECTING A SERIES OF
SHORTWAVES TO EJECT OUT OF THE PARENT TROUGH AND ACROSS THE GREAT
BASIN BEGINNING WEDNESDAY. THE THREAT OF CONVECTION WILL EXIST
WITH EACH OF THESE FEATURES...THOUGH THE MORE ACTIVE CONVECTION
WILL LIKELY HOLD OFF UNTIL THE MAIN LOW FINALLY REACHES THE WEST
COAST STATES LATE IN THE WEEK.

AT THIS TIME THE MEMORIAL DAY WEEKEND LOOKS TO HAVE AT LEAST A
WET/COOL START AS THE UPPER TROUGH MOVES INTO THE GREAT BASIN.
BOTH THE GFS AND ECMWF BRING A SUBSTANTIAL FEATURE THROUGH UTAH
DURING THE WEEKEND...WITH THE GFS A BIT FASTER EJECTING THIS
FEATURE OUT OF THE AREA LATE IN THE WEEKEND. MEMORIAL DAY WOULD BE
DRIEST OF THE DAYS...THOUGH SPOTTY LINGERING SHOWERS AND COOL
TEMPS MORE THAN LIKELY IN THIS SITUATION.

&&

.AVIATION...LIGHT NORTHWEST WINDS WILL TURN TO THE DRAINAGE SOUTHEAST
BETWEEN 04-05Z. OCCASIONAL CEILINGS BETWEEN 10-12KFT WILL SPREAD
NORTH INTO THE TERMINAL AREAS AFTER 08Z.

&&

.SLC WATCHES/WARNINGS/ADVISORIES...
UT...NONE.
WY...NONE.
