AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
1015 PM MDT TUE SEP 18 2007

.SYNOPSIS...STRONG SOUTHWEST FLOW WILL DEVELOP AHEAD OF A POTENT
PACIFIC SYSTEM WEDNESDAY AND THURSDAY. DEEP MOISTURE SPREADS INTO
THE AREA FRIDAY NIGHT THROUGH SATURDAY.

&&

.DISCUSSION...FLOW IS BACKING TO SOUTHWEST ACROSS NORTHERN UTAH AS
FLAT RIDGING MOVES EAST OUT OF THE STATE. WARM ADVECTION CLOUDS ARE
SET UP ACROSS THE NORTHERN THIRD OF THE STATE. IT IS UNLIKELY THAT
ANY MEASURABLE PRECIP WILL FALL...BUT SKIES ARE LOOKING TO BE MORE
CLOUDY THAN FORECAST. WILL PROBABLY DO A QUICK UPDATE TO ADDRESS
THIS. TEMPS MAY ALSO END UP A FEW DEGREES HIGHER SO MAY BUMP THOSE
UP AS WELL.

LITTLE CHANGE IN THE SYNOPTIC SCALE PATTERN FOR THE NEXT FEW DAYS.
THE DIGGING PACIFIC CUTOFF DROPPING SOUTHWARD ALONG THE COAST IS
RATHER IMPRESSIVE ON WV IMAGERY. THE MODEL TRENDS HAVE STABILIZED
AND HAVE THE LOW SPINNING OFF THE CA COAST THROUGH FRIDAY
AFTERNOON...THEN LIFTING EASTWARD ACROSS UTAH ON SATURDAY. THE DEVIL
REMAINS IN THE DETAILS OS WHAT SENSIBLE WEATHER RESULTS.

WINDS AHEAD OF THE LOW WILL BE STRONG FOR THE NEXT FEW DAYS. EXPECT
WEDNESDAY TO BE THE WORST AS FAR AS WINDS WITH 40-50KT SUSTAINED AT
700MB. WILL LIKELY BE A HIGH END ADVISORY RATHER THAN A WIND
WARNING. HEAVILY WORDED HWO WAS ISSUED ALONG WITH MUCH OF THE
WESTERN PART OF THE STATE UNDER A RED FLAG WARNING. WILL LIKELY
ISSUE A WIND ADVISORY WITH THE AM PACKAGE. WINDS WILL REMAIN  NEAR
ADVISORY LEVEL THURSDAY AND FRIDAY SO THIS MAY BE A EXTENDED EVENT.

THE NEXT BIG ISSUE IS HEAVY RAINFALL. A DEEP MOISTURE SURGE IS DRAWN
INTO THE STATE. THE OVERALL PATTERN LOOKS GOOD FROM A CONCEPTUAL
MODEL POINT OF VIEW...WITH THE BEST ASCENT ON THE NORTHEAST SIDE OF
THE CUTOFF TAPPING THE SUBTROPICAL JET AND FEEDING IT INTO UTAH
SATURDAY MORNING. BASINWIDE MODEL QPF APPROACHES AND EXCEEDS 1 INCH
FOR MUCH OF WESTERN UTAH. THIS MAY BE A SIGNIFICANT FLASH FLOOD
EVENT IN SOUTHERN UTAH SATURDAY.

THE EVENT WILL BE OVER FOR THE MOST PART BY...BUT THE GFS HINTS AT
SOME WRAPAROUND MOISTURE LINGERING INTO SUNDAY NIGHT ACROSS NORTHERN
UTAH. COOLER TEMPS INTO EARLY NEXT WEEK WITH A FREEZE POSSIBLE IN
SOME OF THE NORTHERN VALLEYS.

&&

.AVIATION...DRAINAGE WILL SET UP AT SLC WITHIN THE NEST FEW HOURS
AND GRADUALLY STRENGTHEN OVERNIGHT. GUSTY SOUTHERLY WINDS WEDNESDAY
WITH NO LAKE BREEZE ANTICIPATED.

&&

.FIRE WEATHER...RED FLAG WARNING UNCHANGED SINCE ITS ISSUANCE. RH
VALUES MAY NOT DROP BELOW 15 PERCENT...BUT IN RESPONSE TO LOCAL
COORDINATION WITH FIRE AGENCIES...20 PERCENT IS THE CUTOFF FOR THIS
EVENT DUE TO RECENT DRY SPELL.

&&

.SLC WATCHES/WARNINGS/ADVISORIES...
UT...RED FLAG WARNING FROM NOON TO 9 PM WEDNESDAY FOR
     FIRE WEATHER ZONES UTZ420-423-434-435-437-439-440.
WY...NONE.
