AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
423 PM MDT SAT APR 19 2008

.SYNOPSIS...THE NEXT COLD PACIFIC TROUGH WILL MOVE INTO THE NORTHERN
GREAT BASIN EARLY SUNDAY. THE ASSOCIATED COLD FRONT WILL SWEEP
ACROSS THE REGION SUNDAY. COOL AND UNSETTLED WEATHER WILL REMAIN
OVER MUCH OF THE STATE THROUGH THE COMING WEEK.

&&

.DISCUSSION...ABOVE NORMAL TEMPERATURES AND WINDY CONDITIONS ARE
OCCURRING ACROSS MUCH OF THE FORECAST AREA TODAY AHEAD OF THE
APPROACHING TROUGH. WINDS HAVE BEEN PRIMARILY ADVISORY LEVEL IN
WESTERN UTAH. LOCATIONS OUTSIDE THE ADVISORY AREA HAVE BEEN GUSTY
BUT BELOW ADVISORY CRITERIA...SO THE WIND ADVISORY HAS NOT BEEN
EXPANDED. IN ADDITION...THE RED FLAG WARNING WAS EXTENDED THROUGH
TOMORROW...AS GUSTY WINDS WITH A DRY AIRMASS IN SOUTHERN UTAH ARE
EXPECTED TO CONTINUE.

THE COLD PACIFIC TROUGH IS CURRENTLY CENTERED OVER WESTERN OREGON
AND WASHINGTON...AND IS EXPECTED TO DIG FURTHER INLAND THIS
EVENING. COLD AIR BEGINS TO MOVE INTO NORTHWEST UTAH
OVERNIGHT...BUT THE COLDEST AIR DOES NOT ENTER THE AREA UNTIL
AROUND 12Z SUNDAY...WITH THE 700 MB BAROCLINIC ZONE SITTING
DIRECTLY ON TOP OF NORTHERN UTAH AND SOUTHWEST WYOMING THROUGH
MUCH OF THE DAYLIGHT HOURS ON SUNDAY. THE LATEST RUNS OF THE GFS
AND NAM HAVE TRENDED TOWARD THE EC SOLUTION...ALLOWING THE 700 MB
COLD AIR TO MOVE FURTHER SOUTHWARD INTO MUCH OF THE STATE OF UTAH.
ALL MODELS HAVE ALSO STARTED PRODUCING AT LEAST SOME QPF OVER
NORTHERN UTAH...SO POPS AND QPF HAVE BEEN KEPT ABOUT THE SAME
ACROSS THE CWA. AS FAR AS PRECIPITATION TYPE IS CONCERNED...WHILE
SURFACE TEMPERATURES IN THE NORTHERN VALLEYS MAY BE AS HIGH AS THE
UPPER 40S ON SUNDAY MORNING...A DRY SUB-CLOUD LAYER BRINGS WET
BULB ZEROS TO 4500 FT MSL OR BELOW. WHILE PRECIP MAY BEGIN VERY
BRIEFLY AS RAIN...LOCAL STUDIES INDICATE THAT PRECIP TYPE WILL BE
PRIMARILY SNOW WITH WET BULB ZEROS THIS LOW.

IN THE EXTENDED...BOTH THE GFS AND EC KEEP AN ACTIVE WESTERLY FLOW
THROUGH AT LEAST THURSDAY MORNING. ENSEMBLE FORECASTS INDICATE
THAT THE EC WAS TOO COLD IN DAYS 3 THROUGH 6...SO TEMPS WERE BASED
PRIMARILY ON GFS AND ENSEMBLE SOLUTIONS. BEYOND DAY 6 THE GFS
PRODUCES A HIGH AMPLITUDE RIDGE THAT IS NOT SUPPORTED BY ANY OTHER
MODELS OR ENSEMBLES...SO THE UNSEASONABLY WARM TEMPERATURES IT WAS
PRODUCING FOR FRIDAY WERE IGNORED AND NUDGED CLOSER TO
CLIMATOLOGY. HOWEVER...THE LATEST EC RUN DOES PRODUCE A RIDGE ON
SATURDAY...SO A RIDGE FOR NEXT WEEKEND MAY NOT BE OUT OF THE
QUESTION.

&&

.AVIATION...STRONG AND GUSTY SOUTH WINDS AT THE SLC TERMINAL WILL
CONTINUE INTO THE EVENING HOURS AHEAD OF A COLD FRONT ARRIVING
OVERNIGHT. THERE IS A 20 PERCENT CHANCE OF BRIEF HIGH-END MVFR
CONDITIONS IN BLOWING DUST THROUGH THIS EVENING. OTHERWISE...VFR
CONDITIONS WILL PREVAIL THROUGH EVENING WITH INCREASING MID AND HIGH
LEVEL CLOUDS.

&&

.FIRE WEATHER...STRONG WINDS AND A VERY DRY AIRMASS HAVE COMBINED TO
PRODUCE WIDESPREAD CRITICAL FIRE WEATHER CONDITIONS ACROSS EXTREME
SOUTHWEST AND SOUTH CENTRAL UTAH WHERE FUELS ARE DRY. WINDS WILL
DECREASE SOME OVERNIGHT AS RELATIVE HUMIDITY VALUES RECOVER...BUT
STRONG AND GUSTY WINDS ARE EXPECTED TO REDEVELOP SUNDAY AS A COLD
FRONT MOVES TOWARD THE AREA. THE AIRMASS WILL BE CRITICALLY DRY ONCE
AGAIN...SO THE RED FLAG WARNING HAS BEEN EXTENDED UNTIL SUNDAY
EVENING.

&&

.SLC WATCHES/WARNINGS/ADVISORIES...
UT...RED FLAG WARNING UNTIL 9 PM SUNDAY FOR UTZ019-UTZ020.

     WIND ADVISORY UNTIL MIDNIGHT SUNDAY FOR UTZ003-UTZ005-UTZ007-
     UTZ008-UTZ015-UTZ016.

WY...NONE.
