AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SEATTLE WA
930 AM PST WED NOV 22 2011

.SYNOPSIS...A STRONG FRONTAL SYSTEM WILL BRING RAIN AND SNOW TO THE
MOUNTAINS OF WEATHER TO WESTERN WASHINGTON THROUGH WEDNESDAY
MORNING. THE STRONGEST WINDS HAVE SHIFTED SOUTH OF WESTERN
WASHINGTON THIS MORNING BUT WILL CONTINUE TO BE BREEZY ACROSS THE
AREA TODAY. ANOTHER STRONG FRONT WILL BRING MORE WIND TO TO WESTERN
WASHINGTON...POSSIBLY DAMAGING WINDS ALONG THE COAST AND NORTH
INTERIOR ON THURSDAY. MORE RAIN AND MOUNTAIN SNOW WILL ARRIVE ON
THURSDAY AFTERNOON CAUSING TRAVEL DIFFICULTY ACROSS THE PASSES
THROUGH FRIDAY MORNING.

&&

.SHORT TERM...A VERY WELL DEFINED FRONT PUSHED THROUGH THE N
INTERIOR AROUND 6 AM AND THROUGH PUGET SOUND SHORTLY AFTER 7 AM WITH
ABRUPT WIND SHIFTS FROM THE S TO THE W/SW. DAMAGING WINDS OCCURING
OVERNIGHT ALONG PARTS OF THE COAST AND N INTERIOR WITH GUSTS UP TO
60 MPH REPORTED. WINDS HAVE DIED DOWN DRAMATICALLY ACROSS BASICALLY
ALL OF WRN WA WITH THE STRONGEST WINDS SHIFTING S AND EWD INTO
OREGON. EVEN THE WLY FLOW THROUGH THE STRAIT IS IS SUB ADVISORY
LEVELS AND SW WINDS WE OFTEN SEE COME UP POST FRONTAL IN PUGET SOUND
ARE LIKELY TO JUST BE BREEZY TODAY IN THE 15 TO 25 MPH RANGE
SUSTAINED. WILL LIKELY DROP THE CURRENT WIND WARNING FOR THE FOR THE
N INTERIOR SHORTLY. THE WIND ADVISORY FOR SRN SECTIONS WAS ALREADY
DROPPED EARLIER.

THE OTHER CONCERN TODAY IS THE ONGOING PRECIPITATION WHICH HAS
FALLEN AS HEAVY SNOW IN SOME PLACES AND HEAVY RAIN IN OTHERS. THE
WARM AIR MOVED IN UNEVENLY OVERNIGHT WITH PASSES TRAPPING COLD AIR
AND MOST THE CASCADES STAYING MOSTLY AS SNOW ABOVE 3500 FEET LAST
NIGHT. IT APPEARS WE EASILY HIT WINTER STORM CRITERIA WITH SEVERAL
LOCATIONS REPORTING 12-18 INCHES...AND MOUNT BAKER POSSIBLY THE
WINNER WITH 24 INCHES SO FAR. HEAVY RAIN HAS FALLEN ACROSS LOWER
SLOPES OF THE CASCADES AND ESPECIALLY THE OLYMPICS. THE IMMEDIATE
CONCERN IS FOR BASINS IN THE OLYMPICS...BUT WITH SNOW LEVELS RISING
IN THE CENTRAL CASCADES TODAY THERE ARE OTHER CONCERNS THERE. FOR
HYDRO DETAILS PLEASE SEE THE HYDRO SECTION BELOW.

THE FRONTAL BAND AND HEAVIEST PRECIP HAS SHIFTED SWD...MAINLY
AFFECTING THE CENTRAL CASCADES AND FAR SRN PORTIONS OF THE FORECAST
AREA THIS MORNING. THIS WILL ALLOW COLDER AIR AND LOWER SNOW LEVELS
TO HANG IN ACROSS THE N CASCADES BUT SNOW LEVELS ACROSS THE CENTRAL
CASCADES BUT MORE PROBLEMATIC. MODELS SHOW THE MAIN MOISTURE BAND TO
LIFT BAND NWD LATER TODAY AND THIS EVENING AS A WAVE FORMS ALONG THE
BAROCLINIC BAND OFF THE OREGON COAST. LOW PRESSURE RIPPLES NWD AND
EVENTUALLY MOVES MOVES JUST N OF THE CENTRAL CASCADES WHICH WILL
CAUSE SNOW LEVELS TO RISE TO ABOVE 5500 FEET THERE LATER TODAY AND
TONIGHT. PASSES WILL BE SLOW TO MIX OUT WITH A WINTRY MIX OF
SNOW/SLEET/AND POSSIBLY FREEZING RAIN BEFORE GOING TO RAIN IN MANY
PLACES. WILL KEEP THE SNOW ADVISORY FOR THE CENTRAL CASCADES AND
OLYMPICS IN PLACE UNTIL 6 PM BUT INDICATE THE MIXED PRECIP POTENTIAL
IN THE PASSES AND THE MAIN SNOW LEVELS RISING. FOR THE N CASCADES IT
APPEARS COLDER AIR WILL HANG IN THERE WITH MOUNT BAKER LIKELY TO
REALLY PILE UP ADDITIONAL SNOW. WILL EXTEND THE WARNING THERE TROUGH
10 AM WEDNESDAY AS THE REST OF THE PRECIP SHOULD FALL AS SNOW
POSSIBLY MIXED WITH SLEET AT TIMES.

THIS FIRST EVENT SLOWLY UNWINDS AS FAR AS SNOW IS CONCERNED
WEDNESDAY MORNING. THERE WILL BE A SHORT BREAK BETWEEN WEATHER
SYSTEMS WEDNESDAY AFTERNOON WEDNESDAY NIGHT.

ANOTHER VERY STRONG FRONTAL SYSTEM SIMILAR TO THE ONE THAT IS
CURRENTLY AFFECTING WRN WA WILL MOVE INTO THE AREA THANKSGIVING DAY.
HIGH WINDS WILL AGAIN BE A BIG CONCERN IN THE SAME SPOTS THAT GOT
HIGH WINDS OVERNIGHT. WILL HOIST A HIGH WIND WARNING FOR THE
N/CENTRAL COAST...AND FOR THE ADMIRALTY INLET AREA NWD FROM EARLY
THURSDAY MORNING THROUGH THE AFTERNOON. WINDS AGAIN COULD GUSTS TO
55-60 MPH IN THOSE SPOTS. PRECIP WILL BE A LITTLE SLOWER TO REACH
THE CASCADES...BY AFTERNOON. WILL DECIDED ON A WINTER STORM WATCH
FOR THE MOUNTAINS BEFORE THE AFTERNOON FORECAST PACKAGE. THE INITIAL
MODEL RUNS THIS MORNING SUGGEST THAT SNOW LEVELS WILL BE LOWER AND A
FOOT OR MORE OF SNOW COULD BE POSSIBLE IN OLYMPICS AND CASCADES
THROUGH FRIDAY MORNING...AFFECTING HOLIDAY TRAVEL THROUGH THE
PASSES.  MERCER

.LONG TERM...PREVIOUS DISCUSSION FOLLOWS...AN UPPER RIDGE WILL MOVE
OVER THE AREA FRIDAY FOR A FAIRLY TRANQUIL WEATHER DAY. LONG RANGE
MODELS ARE IN FAIR AGREEMENT WITH A QUASI-PINEAPPLE EXPRESS TYPE
PATTERN SETTING UP OVER THE WEEKEND...MAINLY POINTED AT VANCOUVER
ISLAND SATURDAY THEN SAGGING SOUTH THROUGH WESTERN WASHINGTON
SUNDAY. DRIER WEATHER IS EXPECTED MONDAY AS AN UPPER RIDGE REBUILDS
OVER THE REGION. SCHNEIDER

&&

.HYDROLOGY...TWO FRONTAL SYSTEMS WILL PRESENT A THREAT OF FLOODING
ON WESTERN WASHINGTON RIVERS IN THE SHORT TERM. THE FIRST OF THESE
WAVES MOVED INTO THE AREA LAST NIGHT...BRINGING 2 TO 6 INCHES OF
PRECIPITATION TO THE OLYMPIC MOUNTAINS AND DRIVING THE SNOW LEVEL TO
AROUND 5500 FT. LESS PRECIPITATION HAS FALLEN ELSEWHERE...GENERALLY
1 TO 4 INCHES OVER THE CASCADES AND SOUTHWEST WASHINGTON. THAT
FEATURE IS SHIFTING SOUTHEAST...WITH THE FOCUS OF THE HEAVIEST RAIN
OVER THE SOUTH OLYMPICS...SOUTHWEST WASHINGTON...AND THE CENTRAL AND
SOUTH WASHINGTON CASCADES FOR THE REST OF TODAY.

THE SECOND FRONTAL WAVE WILL SHIFT THE HEAVY PRECIPITATION A BIT
FURTHER NORTH AGAIN TONIGHT AND WEDNESDAY...BEFORE IT EVENTUALLY
PROGRESSES EASTWARD. IN TOTAL THOUGH...THE HEAVIEST PRECIPITATION
WILL STILL BE CONCENTRATED ACROSS THE SOUTHERN TWO-THIRDS OF THE
FORECAST AREA. PRECIPITATION AMOUNTS OF 2 TO 4 INCHES ARE LIKELY
OVER THE HIGHER TERRAIN WITH 1 TO 2.5 INCHES OVER THE LOWLANDS. THE
SNOW LEVEL WILL BE AROUND 3000 TO 4000 FT.

A FLOOD WARNING IS IN EFFECT FOR THE SKOKOMISH RIVER...AND IT WILL
REACH FLOOD STAGE WITHIN THE NEXT COUPLE HOURS.

A FLOOD WATCH CONTINUES FOR THE OLYMPIC PENINSULA. THE RIVER OF
PRIMARY CONCERN THERE IS THE ELWHA...IN PART DUE TO UNCERTAINTY IN
ITS BEHAVIOR SINCE THE DAMS THERE WERE RECENTLY REMOVED.

A FLOOD WATCH CONTINUES ALSO FOR THE INTERIOR COUNTIES FROM
SNOHOMISH COUNTY SOUTHWARD. MINOR FLOODING IS POSSIBLE ON THE
NEWAUKUM...CHEHALIS...PUYALLUP RIVER NEAR ORTING...AND THE
SNOQUALMIE AND STILLAGUAMISH RIVERS.

IT STILL APPEARS THAT THE THREAT OF FLOODING IS LIMITED TO THE MOST
FLOOD-PRONE RIVERS WITHIN THE WATCH AREA. HOWEVER THE LATEST RUN OF
THE HYDROLOGIC MODELS AT THE NWS NORTHWEST RIVER FORECAST CENTER IS
FORECASTING SOMEWHAT HIGHER LEVELS IN THE CHEHALIS BASIN...WITH
MINOR TO MODERATE FLOODING A GOOD POSSIBILITY THERE. ELSEWHERE THE
FLOODING THAT DOES OCCUR SHOULD BE RELATIVELY MINOR.

FINALLY IT SHOULD BE NOTED THAT A SCENARIO LIKE THIS...WITH
PRECIPITATION ARRIVING IN MULTIPLE SYNOPTIC WAVES...DOES LEAVE A
HIGHER DEGREE OF UNCERTAINTY. THE BOTTOM LINE THEN IS STAY TUNED FOR
UPDATES AND REVISIONS TO THE FORECAST.  FELTON/MCDONNAL

&&

.AVIATION...THE STRONG FRONTAL SYSTEM THAT BROUGHT HEAVY RAIN AND
WINDY CONDITIONS TO NORTHWEST WASHINGTON OVERNIGHT HAS SHIFTED SOUTH
INTO CENTRAL AND NORTHWESTERN OREGON. THE MOISTURE PLUME ASSOCIATED
WITH THIS FRONT...ALONG WITH STRONG SOUTHWEST WINDS ALOFT...HAS
SHIFTED SOUTHEAST TO A LONE FROM ABOUT THE NORTHERN CASCADES TO
ASTORIA OREGON. THIS AREA OF MOISTURE AND STRONG WINDS ALOFT WILL
SHIFT BACK TO THE NORTH LATER TODAY THROUGH TONIGHT...THEN WILL SAG
SOUTHEAST OF THE AREA BY MIDDAY WEDNESDAY. THE COMBINATION OF
LIGHTER LOW LEVEL FLOW BELOW 2000 FEET AND RAINFALL WILL RESULT IN
LOWERING CEILINGS AND VISIBILITIES INTO THE LOWER END OF MVFR FROM
SOUTH TO NORTH DURING THE AFTERNOON AND EVENING HOURS HOURS. MVFR TO
LOCAL IFR CEILINGS AND VISIBILITIES ARE EXPECTED TONIGHT THROUGH WED
MORNING AS PRECIPITATION FALLS INTO A STABLE BOUNDARY LAYER. WINDS
HAVE EASED TO SW 20-35KT AT 850 MB THIS MORNING. S-SW WINDS 60-75 KT
AT 5000 FT WILL DEVELOP THIS AFTERNOON AND CONTINUE THROUGH TONIGHT.

KSEA...RAIN WILL INCREASE AGAIN THIS AFTERNOON AND CONTINUE THROUGH
TONIGHT. SCT-BKN018 OVC040 WITH OCNL -RA WILL BECOME 4SM RA OVC015
AFTER 22Z AND CONTINUE THROUGH 15Z WED. CONDITIONS GRADUALLY
IMPROVING WED MORNING. WIND S10 KT SHIFTING BECOMING LIGHT THIS
AFTERNOON AND TONIGHT...BUT WIND AT 050 INCREASING TO S45 KT
00Z...SW 70KT AT 06Z. WIND AT 020 INCREASING TO S 45 KT 02Z-05Z AND
CONTINUING THROUGH ABOUT 15Z WED GIVING LLWS. ALBRECHT

&&

.MARINE...THE STRONG FRONT THAT MOVED THROUGH THE WATERS HAS SHIFTED
SOUTH INTO THE CENTRAL OREGON WATERS. THE FRONT WILL LIFT BACK TO
THE NORTH TONIGHT AND MAY RESULT IN A SMALL AREA OF S WIND 30 KT
NEAR GRAYS HARBOR BAR. THE FRONT WILL SHIFT BACK TO THE SE OF THE
AREA WED MORNING. LOCAL SMALL CRAFT ADVISORY WINDS ARE EXPECTED
ALONG THE COAST...THROUGH THE STRAIT...AND OVER THE NORTHERN INLAND
WATERS AS CONTINUE STRONG WINDS ALOFT INTERACT WITH THE TERRAIN.
SMALL CRAFT ADVISORY CONDITIONS FOR HAZARDOUS SEAS WILL CONTINUE
ALONG THE COAST AND AT THE WEST ENTRANCE TO THE STRAIT AS A 15-17 FT
SWELL MOVES IN FROM THE WEST.

ANOTHER STRONG FRONT WILL APPROACH THE WATERS FROM THE WEST WED
NIGHT AND WILL SWEEP THROUGH THE WATERS THU. EXPECT STORM FORCE
WINDS TO DEVELOP ON THE COAST...AT THE EAST ENTRANCE TO THE
STRAIT...AND IN THE NORTHERN INLAND WATERS AHEAD OF THIS FRONT WITH
GALES IN OTHER WATERS EXCEPT PUGET SOUND AND HOOD CANAL. GALE AND
