AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
946 AM MST SAT NOV 20 2010

.SYNOPSIS...A STRONG MOIST SOUTHWEST FLOW IS OVER THE AREA TODAY
AS THE FIRST IN A SERIES OF INCREASINGLY COLD STORM SYSTEMS MOVES
INTO THE REGION. THIS FIRST SYSTEM WILL MOVE EAST TONIGHT WITH
ADDITIONAL STORMS CROSSING THE AREA THROUGH TUESDAY.

&&

.DISCUSSION...WATER VAPOR LOOP SHOWS A SHORTWAVE TRAVERSING NEVADA
WITH A COLD UPPER LOW SINKING SOUTH ALONG THE PACIFIC NORTHWEST
COAST. ACARS 400-250MB WIND OBSERVATIONS INDICATE A 110-145KT
SOUTHWESTERLY JET FROM CENTRAL CALIFORNIA INTO SOUTHWEST IDAHO. JET
COUPLING WAS TAKING PLACE ACROSS SOUTHERN IDAHO WITH A SECOND JET
FROM CENTRAL IDAHO INTO THE UPPER MIDWEST. 12Z 700MB ANALYSIS PLACES
A CYCLONE OFF THE PACIFIC NORTHWEST COAST. -3C WAS REPORTED AT SLC.
12Z KSLC RAOB SHOWS 5C OF COOLING IN THE LOWER LEVELS DURING THE
PAST 24 HOURS...WITH LITTLE THERMAL CHANGE IN THE MID LEVELS.
SATURATION WAS OCCURRING ABOVE 650MB. STRONG WARM ADVECTION
SIGNATURE WITH THE WINDS VEERING WITH HEIGHT.

GOES SOUNDER/RUC AND GPS PRECIPITABLE WATER SENSORS INDICATE VALUES
RANGE FROM A QUARTER TO THIRD OF AN INCH ACROSS EASTERN UTAH...TO
OVER A HALF INCH ACROSS WESTERN AND NORTHERN UTAH.

UPDATING TO INCREASE WINDS ACROSS THE CENTRAL AND SOUTHERN VALLEYS.
HAVE OPTED TO INCLUDE A WIND ADVISORY FOR THESE AREAS...AS FAR NORTH
AS OGDEN. CURRENT OBSERVATIONS INDICATE WINDS IN THESE AREAS
CONTINUE TO INCREASE THIS MORNING WITH 700 MB FLOW INCREASING TOWARD
50KTS BY EVENING. WINDS WILL DIMINISH FROM NORTH TO SOUTH THIS
AFTERNOON AND EVENING WITH THE FRONTAL PASSAGE...AND SOUTHWEST TO
NORTHEAST AS PRECIPITATION DEVELOPS ACROSS SOUTHERN UTAH.
ANTICIPATE ONLY MARGINAL WIND ADVISORY CONDITIONS ALONG THE
ARIZONA BORDER.

OTHERWISE...PRECIPITATION ON TRACK TO INCREASE THIS AFTERNOON ACROSS
NORTHERN AND WESTERN UTAH WITH THE APPROACH OF THE SHORTWAVE FROM
NEVADA. MOUNTAIN AREAS FAVORED IN SOUTHWESTERLY FLOW WILL CONTINUE
TO SEE BEST SNOW RATES TODAY. RIDGETOP WINDS ARE ALSO QUITE A
CONCERN WITH OBSERVED WINDS OF 70-80 MPH COMMON THIS MORNING.

FOCUS OF AFTERNOON PACKAGE WILL BE POST FRONTAL THIS EVENING THROUGH
THE PASSAGE OF THE ARCTIC BOUNDARY TUESDAY.

WILL CONTINUE TO POST GRAPHICAL NOWCASTS WITHIN HEADLINE SECTION
ATOP OUR WEBPAGE.

PREVIOUS DISCUSSION FOLLOWS...
THE FIRST SHORT WAVE IS EJECTING OUT OF THE LARGE ERN PAC TROF THIS
MORNING WITH SUFFICIENT MOISTURE AND LIFT OUT AHEAD OF IT FOR PRECIP
TO HAVE ALREADY DEVELOPED ACROSS NRN UT.

EXPECT THIS TO BECOME WIDESPREAD DURING THE DAY AS THE WAVE LIFTS
ACROSS THE GREAT BASIN AND THE FRONTAL BOUNDARY WORKS SLOWLY EAST.
THIS SHOULD PUSH THRU THE NORTH LATE TODAY WITH ENOUGH COOLING FOR
PRECIP TO CHANGE OVER TO SNOW IN THE VALLEYS FROM ABOUT PROVO
NORTH. DONT EXPECT PRECIP TO LAST MUCH PAST THAT SO ANY SNOW
ACCUMULATION SHOULD REMAIN MINOR...AT LEAST ON THE VALLEY FLOORS.

HIGH WINDS SHOULD STILL DEVELOP THIS MORNING ACROSS THE WRN
VALLEYS ALTHO HAVE SOME CONCERNS THAT THEY WILL NOT GET ALL THAT
STRONG IN AREAS WHERE PRECIP HAS ALREADY STARTED...AND PRECIP
COULD BECOME WIDESPREAD ACROSS THE WEST BY LATE MORNING. HAVE
HELD OFF ON ISSUING A WIND ADVISORY FOR OTHER AREAS OUTSIDE OF
THE WARNING FOR THIS SAME REASON.

THE NEXT WAVE TO BRING PRECIP BACK TO UT WILL BE ASSOCIATED WITH
THE LOW ITSELF EJECTING ACROSS THE GREAT BASIN ON SUN. ADDITIONAL
AIRMASS COOLING OVERNIGHT TONIGHT BEHIND THE INITIAL WAVE SHOULD
RESULT IN PRECIP FALLING AS SNOW IN ALL BUT THE LOWEST SOUTHERN
VALLEYS RIGHT AT THE ONSET. THIS WAVE MOVES PAST LATE SUN THRU SUN
EVE WITH ANOTHER COLD FRONT CROSSING THE CWA. EXPECT A PERIOD OF
HEAVY PRECIP WITH THIS FRONT AND HAVE ADJUSTED TIMING OF THE
WINTER STORM WATCH FOR THE WASATCH FRONT VALLEYS TO BETTER ALIGN
WITH THIS FEATURE.

COLD MOIST WESTERLIES FOLLOW THIS TROF FOR MON WITH AN ADDITIONAL
SHORT WAVE ENHANCING PRECIP DURING THE DAY.

MODELS CONTINUE TO DIFFER ON HOW FAR WEST THE ARCTIC AIR WILL GET
AND HOW COLD IT WILL BE ONCE IT ARRIVES IN THE CWA WITH THE FINAL
SHORT WAVE FOR TUE. THE GFS CONTINUES TO MODIFY THIS AIRMASS AS IT
SPILLS WEST OF THE NRN ROCKIES. THIS RESULTS IN THE COLD CORE
REMAINING MAINLY EAST OF THE DIVIDE AS THIS WAVE DIVES SEWD. THE
00Z EC CONTINUES TO INDICATE AN UNMODIFIED OR LESS MODIFIED AIRMASS
PERSISTS WEST OF THE DIVIDE AND DEPICTS A MUCH SHARPER...DEEPER
AND SLOWER SHORT WAVE FOR TUE INTO TUE NIGHT.

THE LATEST 06Z NAM ALSO HAS A SHARPER SLOWER WAVE FARTHER W BUT
IT DOES MODIFY THE AIRMASS. AS THIS IS THE FIRST REAL COLD PUSH OF
THE WINTER...AND IT IS EARLY IN THE WINTER SEASON...SUSPECT THAT
THE ARCTIC AIR WILL INDEED MODIFY SOMEWHAT ONCE IT CROSSES WEST
OF THE DIVIDE SO HAVE LEANED TOWARDS THE GFS SOLUTION FOR TUE THRU
FRI...WITH SOME ADJUSTMENT TOWARDS THE EC/NAM TIMING.

&&

.AVIATION...NEAR TERM CONCERNS FOR THE KSLC TERMINAL WILL REVOLVE
AROUND INCREASINGLY GUSTY SOUTH WINDS AND LOWERING CEILINGS. FIRST
WINDS...GUSTS OF GREATER THAN 30MPH WILL INCREASE TO GUSTS RANGING
FROM 40-50MPH BETWEEN 18Z-22Z THIS AFTERNOON. NOW CEILINGS...CIGS
WILL BEGIN TO FALL RAPIDLY AFTER 18Z...WITH SUB 6000FT AGL CIGS
DEVELOPING FOR THE AFTERNOON HOURS. RAIN SHOWERS TO INCREASE THIS
AFTERNOON.

FURTHER OUT...A STRONG COLD FRONT WILL SURGE THROUGH THE TERMINAL
BETWEEN 23-01Z THIS EVENING SWITCHING WINDS TO NORTHWEST. STEADY
RAIN AND MVRF CIGS/VIS LIKELY...WITH A SWITCH TO IFR WET SNOW
EXPECTED BETWEEN 01-03Z. BRIEF SLUSH ON THE RUNWAYS POSSIBLE LATE
EVENING.
