AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
952 AM MST FRI NOV 14 2008

.SYNOPSIS...A COOL DRY NORTHERLY FLOW WILL CONTINUE OVER THE AREA
TODAY. A STRONG RIDGE WILL THEN BUILD INTO THE AREA OVER THE WEEKEND
AND REMAIN IN PLACE THROUGH LATE NEXT WEEK.

&&

.DISCUSSION...STRONG WINDS OVER THE HIGHER TERRAIN WILL DIMINISH THROUGH
THE REMAINDER OF THE DAY. GAP WINDS MAY DEVELOP ACROSS FAR
SOUTHWEST UTAH TONIGHT. A STAGNANT PATTERN DEVELOPS THIS WEEKEND
INTO NEXT WEEK...INCREASING HAZE AS VALLEYS FAIL TO MIX FOR AN
EXTENDED PERIOD OF TIME.

WATER VAPOR LOOP SHOWS A RIDGE AMPLIFYING OFF THE CALIFORNIA COAST.
ACARS 400-250MB WIND OBSERVATIONS REVEAL A NORTHERLY 150-200KT JET
OVER THE NORTHERN AND CENTRAL ROCKIES. 12Z 700MB ANALYSIS PLACED A
RIDGE BUILDING IN FROM CALIFORNIA...WITH THE TIGHTEST GRADIENT OVER
THE ROCKIES.

MODELS INDICATE THAT 700MB WINDS WILL WEAKEN THROUGHOUT THE DAY AS
THE SUBSIDENCE INVERSION LOWERS BELOW MOUNTAINTOPS. THUS...HIGH WIND
EVENT IN THE HIGHER TERRAIN SHOULD BE COMING TO AN END. WITH
OBSERVED PRECIPITABLE WATER VALUES NEAR THE 25TH PERCENTILE OF
CLIMATOLOGY TODAY...EXPECT CLEAR SKIES EXCEPT FOR EARLY STRATUS NEAR
EVANSTON AND CIRRUS ACROSS SOUTHERN UTAH.

12Z KSLC RAOB INDICATES ABOUT 5C OF COOLING BETWEEN THE SURFACE AND
650MB DURING THE PAST 24 HOURS...WITH THE COLD FRONTAL PASSAGE WHICH
OCCURRED YESTERDAY AFTERNOON. TEMPERATURES STRUGGLE TO REACH 50F
NORTHERN VALLEYS...NEAR 70F ACROSS FAR SOUTHERN UTAH.

ATTENTION SHIFTS TO FAR SOUTHWEST UTAH WHERE STRONG GAP WINDS COULD
DEVELOP LATE TODAY AND TONIGHT. WHILE THE SURFACE GRADIENT WILL
TIGHTEN THERE OVERNIGHT...700MB WINDS AND COLD ADVECTION SHOULD
DECREASE AT THE SAME TIME...SO THE EVENT MAY END UP BEING MARGINAL
FOR HEADLINES.

EXPECT TEMPERATURES TO PLUMMET TONIGHT UNDER MOSTLY CLEAR SKIES AND
LIGHT WINDS. HOWEVER...WITH INCREASING SUBSIDENCE AHEAD OF THE
BUILDING RIDGE...THIS COLDER AIR WILL BECOME TRAPPED IN SOME OF THE
VALLEY AREAS. SO WHILE HIGHER ELEVATION SITES SHOULD SEE SIGNIFICANT
WARMING INTO THE EARLY PART OF NEXT WEEK AS 700MB TEMPERATURES RISE
TO NEAR 6C...INVERSIONS WILL HOLD VALLEY TEMPERATURES DOWN.

MODEL SPREAD BEGINS TO INCREASE BY THE MIDDLE PART OF NEXT
WEEK...BUT THEY DO AGREE ON ONE THING...THE LACK OF ANY STRONG STORM
SYSTEMS. THE GFS DOES BRINGS A WEAK TROUGH ACROSS MONTANA AND DOWN
THE WESTERN GREAT PLAINS WHICH COULD BRING SLIGHTLY COOLER AIR AND
PERHAPS SOME CLOUDS TO NORTHERN UTAH ON WEDNESDAY.
OTHERWISE...NEITHER THE EC OR GFS HAS ANY SIGNIFICANT STORMS UNTIL
NEXT WEEKEND AT THE EARLIEST. AS A RESULT...EXPECT STAGNANT
CONDITIONS AND INCREASING HAZE AS VALLEYS FAIL TO MIX FOR AN
EXTENDED PERIOD OF TIME.

&&

.AVIATION...VFR CONDITIONS UNDER CLEAR SKIES WILL PERSIST AT KSLC
TERMINAL THROUGH TODAY. NORTHWESTERLY WINDS ARE EXPECTED TO CONTINUE
THROUGH EARLY THIS EVENING. LIGHT SOUTHEAST DRAINGAGE WINDS EXPECTED
TO DEVELOP BETWEEN 03-05Z.

&&

.SLC WATCHES/WARNINGS/ADVISORIES...
UT...HIGH WIND WARNING UNTIL 11 AM FRIDAY FOR UTZ007-UTZ008-UTZ009.

WY...NONE.
