AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
1046 AM MDT TUE SEP 29 2009

.SYNOPSIS...A STRONG SOUTHWEST FLOW WILL BE OVER THE AREA TODAY
AHEAD OF AN APPROACHING PACIFIC STORM. THE COLD FRONT WILL MOVE
INTO NORTHWEST UTAH THIS EVENING AND ACROSS THE STATE BY WEDNESDAY
AFTERNOON. WEAK HIGH PRESSURE WILL BUILD BACK IN LATER THURSDAY
THROUGH FRIDAY.

&&

.DISCUSSION...THE COLD TROF ALONG THE WEST COAST IS ADVANCING
EAST AND SOUTHWEST FLOW OVER OUR CWA IS INCREASING THIS MORNING.
SYSTEM LOOKS ON TRACK TO CROSS THE FORECAST AREA TONIGHT AND WED.
MORNING MODELS ARE IN FAIR AGREEMENT WITH THE NAM NOW CLOSER TO
THE GFS ON FRONTAL TIMING.

WINDS HAVE BEEN INCREASING THE LAST COUPLE OF HOURS ACROSS THE
WEST DESERTS AND SHOULD BECOME STRONG BY NOON AS THE INCREASING
SOUTHWEST FLOW ALOFT MIXES DOWN. ADDED A WIND ADVISORY HIGHLIGHT
TO THE CENTRAL AND SRN MTNS AS SPEEDS THERE WILL BE SIMILAR TO THE
WEST DESERTS BUT CRITERIA IS HIGHER. ALSO ADDED AN ADVISORY FOR THE
SANPETE/SEVIER VALLEYS AS SPEEDS WILL NOT BE QUITE TO WARNING
LEVELS BUT SHOULD REACH ADVISORY LEVELS.

STILL LOOKS LIKE A GOOD PRECIP EVENT FOR THE NORTH AS SOME
TROPICAL MOISTURE WORKS INTO THE SYSTEM TODAY AND GETS INVOLVED
WITH THE FRONT. SNOW LEVELS WILL BE LOWERING WED MORNING AND THERE
MAY EVEN BE SOME FLAKES MIXED IN ON THE BENCHES BUT ANY
ACCUMULATION SHOULD STAY ABV 6000 FT.

LOOKS LIKE A WINDOW FOR POTENTIAL LAKE EFFECT EXISTS BETWEEN ABOUT
00-06Z THU BEFORE STRONG WARMING ALOFT REDUCES THE DEPTH OF THE
INSTABILITY...AS THE LAKE IS QUITE WARM.

THERE IS ALSO A THREAT OF A FREEZE THU MORNING FOR THE WASATCH
FRONT DEPENDING ON HOW FAST THE CLOUDS CLEAR OUT.

CURRENT PACKAGE IN REASONABLE SHAPE AND ONLY CHANGES WILL BE TO
ADD ABOVE MENTIONED HIGHLIGHTS.

&&

.AVIATION...THE SURFACE COLD FRONT APPROACHING NW UTAH WILL GENERATE
INCREASINGLY STRONG SOUTHERLY WINDS THROUGH THIS EVENING. CURRENT
TIMING OF THE FRONTAL PASSAGE AT THE KSLC TERMINAL WILL FALL BETWEEN
05-07Z. SHOWERS/THUNDERSTORMS ASSOCIATED WITH THE FRONT WOULD AFFECT
THE TERMINAL BEGINNING AROUND 04Z. MVFR CEILINGS WILL SETTLE IN
BEHIND THE FRONT AFTER 08Z...WITH STEADY RAIN AND OCCASIONAL MVFR
VSBYS IN HEAVY PRECIP.

&&

.FIRE WEATHER...THE APPROACHING COLD PACIFIC TROUGH WILL PUSH A
SURFACE COLD FRONT INTO EXTREME NW UTAH LATE THIS AFTERNOON..THEN
SWEEP IT ACROSS ALL FIRE DISTRICTS BY EARLY WEDNESDAY AFTERNOON.
INCREASINGLY STRONG SOUTHERLY WINDS COMBINED WITH ALREADY LOW RH
VALUES IN THE VALLEYS WILL LEAD TO SEVERE FIRE WEATHER CONDITIONS
THIS AFTERNOON THROUGH AT LEAST MID-EVENING. MUCH COLDER TEMPS AND
HIGHER RH VALUES DUE TO WIDESPREAD PRECIP WILL FOLLOW THE FRONT FOR
WEDNESDAY. COLD TEMPERATURES WILL LINGER INTO THURSDAY...WITH SOME
DRYING OVER THE SRN FIRE DISTRICTS EXPECTED. FRIDAY/SATURDAY WILL
SEE WARMER/DRIER CONDITIONS...WITH A NEW PACIFIC TROUGH DROPPING
INTO THE WRN GREAT BASIN LATE IN THE WEEKEND.

&&

.SLC WATCHES/WARNINGS/ADVISORIES...
UT...WINTER STORM WARNING FROM 9 PM TUESDAY TO NOON THURSDAY FOR
     UTZ007>009.
