AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
900 PM MDT THU SEP 14 2006

.SYNOPSIS...A MOIST AND UNSTABLE AIRMASS WILL REMAIN ACROSS THE
REGION THROUGH TONIGHT. A COLD AND ENERGETIC PACIFIC STORM SYSTEM
WILL APPROACH THE AREA BY FRIDAY AFTERNOON. THE ASSOCIATED COLD
FRONT WILL MOVE INTO NORTHWEST UTAH FRIDAY NIGHT...THEN SWEEP
SOUTHEAST AS THE CORE OF THE STORM MOVES EAST ACROSS THE NORTHERN
ROCKIES AND NORTHERN GREAT BASIN.

&&

.DISCUSSION...LONGWAVE TROUGH ENCOMPASSES MUCH OF THE WESTERN
CONUS...ANCHORED AROUND CLOSED LOW OVER THE PACIFIC NORTHWEST.
EVENING WATER VAPOR IMAGERY AND OBJECTIVE ANALYSIS DEPICT SHORTWAVE
LIFTING ACROSS INTERMOUNTAIN REGION...WHILE UPSTREAM STRONG JET
DIGGING DOWN BACKSIDE OF TROUGH JUST OFF WA/OR COASTLINE. REGION OF
BROAD LARGE SCALE ASCENT ASSOCIATED WITH COMBINATION OF PASSING
SHORTWAVE AND UPPER LEVEL DIFFLUENCE RESIDES ACROSS THE FORECAST
AREA THIS EVENING. ROUND OF CONVECTION WHICH EARLIER IMPACTED
NORTHERN UT HAS LIFTED NORTHEAST...HOWEVER NEXT ROUND OF
PRECIPITATION CURRENTLY SPREADING ACROSS THE WEST DESERT...AND
SHOULD REACH THE WASATCH FRONT ROUND 10 PM OR SO. FURTHER
SOUTH...CONVECTION CONTINUES TO FIRE ACROSS SOUTHERN NV INTO
SOUTHWEST UT. DEEP LAYER SHEAR IS STRONGER ACROSS THIS AREA...AND
STORMS HAVE EXHIBITED PERSISTENT MID-LEVEL ROTATION. THIS CONVECTION
SHOULD CONTINUE TO SLOWLY SAG SOUTHWARD THROUGH THE OVERNIGHT HOURS.
UPDATED FORECAST EARLIER TO RAISE POPS INTO CATEGORICAL RANGE ACROSS
NORTHERN UT...WITH SCATTERED WORDING ACROSS SOUTHERN UT. LARGE SCALE
LIFT PROGGED TO REMAIN ACROSS NORTHERN UT INTO THE DAYTIME
FRIDAY...WHILE DRIER AIR SPREADS ACROSS SOUTHERN UT. THUS SHOULD SEE
CONTINUED PRECIPITATION ACROSS THE NORTH...WHILE A DRYING TREND
ENSUES ACROSS THE SOUTH.

UPSTREAM SHORTWAVE OFF WA COASTLINE PROGGED TO TRANSLATE INLAND
FRIDAY AS JET ENERGY SPREADS ONSHORE. ASSOCIATED SURFACE FRONT LOOKS
TO REACH THE WASATCH FRONT DURING THE MID AFTERNOON HOURS...THEN
SURGE SOUTH ACROSS THE REMAINDER OF THE FORECAST AREA FRIDAY
NIGHT/EARLY SATURDAY MORNING. 700MB TEMPS PROGGED TO FALL NEAR -6C
BY MIDDAY SATURDAY...WHICH WILL SUPPORT FIRST SNOWFALL OF THE SEASON
ACROSS HIGHER TERRAIN. HWO/SPS COVER THIS POTENTIAL WELL.

&&

.AVIATION...WIDESPREAD STRATIFORM RAIN IS FALLING OVER THE WEST
DESERTS AND WILL MOVE INTO THE KSLC AREA AFTER 04Z. 7000 FOOT
CEILINGS WILL DEVELOP ONCE AGAIN WITHIN 30 MINUTES AFTER RAIN BEGINS
TO FALL. THERE IS A 20 PERCENT CHANCE THAT MVFR CONDITIONS COULD
DEVELOP BETWEEN 06Z AND 08Z. AN ISOLATED LIGHTNING STRIKE IS STILL
POSSIBLE WITH THIS BAND OF SHOWERS. SOUTH WINDS WILL DEVELOP AGAIN
FRIDAY AFTER SUNRISE AS THE WINDS ALOFT MIX DOWN TO THE SURFACE.
FRONTAL BOUNDARY SHOULD MOVE OVER THE AREA AFTER 22Z FRIDAY.

&&

.FIRE WEATHER...WIDESPREAD PRECIPITATION ACROSS WESTERN UT ALLOWED
RH VALUES TO RECOVER EARLY THIS EVENING...THUS CANCELLED RED FLAG
WARNING. WINDS SHOULD BE EVEN STRONGER ON FRIDAY AHEAD OF THE
FRONT.  CONCERNED ABOUT THE POTENTIAL FOR RED FLAG CONDITIONS ACROSS
PORTIONS OF WEST CENTRAL AND SOUTHWEST UTAH ON FRIDAY AFTERNOON.
WINDS WILL CERTAINLY MEET CRITERIA BUT FEEL THAT MINIMUM RELATIVE
HUMIDITY VALUES ARE MARGINAL FOR A WARNING. WITH DECENT COVERAGE OF
SHOWERS ACROSS THE WEST CENTRAL AND SOUTHWEST TONIGHT DO NOT BELIEVE
THAT THE DRYING AHEAD OF THE FRONT ON FRIDAY WILL BE SUFFICIENT TO
CREATE WIDESPREAD RED FLAG CONDITIONS ALTHOUGH ISOLATED LOCATIONS
MAY REACH CRITERIA.

&&

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