AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SEATTLE WA
951 AM PST TUE FEB 21 2012

.SYNOPSIS...STRONG AND MOIST WESTERLY FLOW ALOFT WILL RESULT IN
LOCALLY HEAVY RAIN AT TIMES THROUGH WEDNESDAY MORNING. EXPECT A COLD
FRONT TO SWEEP ACROSS THE AREA LATE TONIGHT OR EARLY WEDNESDAY.
TEMPERATURES. HIGH PRESSURE ALOFT WILL MOVE OVER THE AREA WEDNESDAY
NIGHT AND CONTINUE THROUGH THURSDAY FOR DRIER WEATHER.

&&

.NEAR TERM...THE SNOW HAS BEEN A LITTLE SLOWER TO TRANSITION TO RAIN
IN THE MOUNTAINS...PROMPTING THE ISSUANCE OF A WINTER WEATHER
ADVISORY FOR THE CASCADES ABOVE 4000 FEET. PLACES SUCH AS PARADISE
AND MOUNT BAKER CAN EXPECTED ANOTHER 4-8 INCHES ON TOP OF WHAT HAS
ALREADY FALLEN BY THE END OF THE DAY TODAY. THE SNOW LEVEL IS
EXPECTED TO ABOVE 5500 FEET BY EARLY THIS EVENING.

MEANWHILE...LOCALLY HEAVY RAIN HAS BEEN FALLING IN THE CASCADES TO
STRONG OROGRAPHIC ENHANCEMENT. SOME PLACES LIKE SPADA LAKE HAVE
RECEIVED 1.5 TO 2.5 INCHES OF RAIN IN THE 12-HR PERIOD ENDING AT 9
AM PST THIS MORNING. THIS HAS OF COURSE CAUSED RIVERS SUCH AS THE
TOLT TO RISE SHARPLY. FLOOD WARNINGS HAVE BEEN ISSUED FOR THE
TOLT...SNOQUALMIE...AND PUYALLUP RIVERS.

THE MAIN CHANGES TO THE FORECAST IN THE NEAR TERM WERE TO ADJUST THE
SNOW LEVELS AND THE SNOW AMOUNTS IN THE CASCADES.

.SHORT TERM FROM THE PREV DISCUSSION...
SATELLITE IMAGERY SHOWS A LARGE FETCH OF MOISTURE FROM WEST OF THE
DATELINE NEAR 30N ALL THE WAY TO WESTERN WASHINGTON THIS MORNING.
STRONG WARM ADVECTION WILL GET STARTED TODAY AND CONTINUE THROUGH
WEDNESDAY MORNING...WITH RAIN HEAVY AT TIMES ALONG THE COAST AND
OVER THE MOUNTAINS. THE SNOW LEVELS THIS MORNING WILL START OUT
AROUND 4000 FEET BUT QUICKLY RISE TO 6000 TO 7000 FEET BY LATER THIS
MORNING. AMSU TOTAL PRECIPITABLE WATER IMAGERY NOT THAT IMPRESSIVE
WITH THE TPW VALUES IN THE CORE OF THE MOISTURE FETCH NEAR 1.5
INCHES. WHAT IS IMPRESSIVE IS THE STRENGTH OF THE 850-700 MB WINDS.
MODELS SHOW THE WINDS IN THE LAYER INCREASING TO 50-70 KNOTS THIS
MORNING. THE WESTPORT PROFILES CONFIRMS THIS TRANSITION IS ALREADY
IN PROGRESS WITH THE WINDS AS LOW AS 3000 FEET ALREADY UP TO 50
KNOTS. WITH THE STRONG OROGRAPHIC FLOW EXPECT HEAVY PRECIPITATION
AMOUNTS IN THE CASCADES...ESPECIALLY THE CENTRAL CASCADES WITH THE
WEST TO NORTHWESTERLY FLOW ALOFT...AND TO A LESSER EXTENT THE WEST
SLOPES OF THE OLYMPICS. SEE HYDRO SECTION FOR A MORE DETAILS. ON THE
FLIP SIDE...WITH THE WEST NORTHWESTERLY FLOW ALOFT THE CENTRAL PUGET
SOUND WILL BE SOMEWHAT RAIN-SHADOWED DURING THIS EVENT. AT THIS
POINT IT LOOKS LIKE THE SEATTLE AREA WILL HAVE THE LOWEST TOTAL RAIN
EVENT TOTALS IN THE AREA BY WEDNESDAY AFTERNOON. STILL HAVE HIGH
POPS FOR THE SEATTLE AREA BUT EXPECTING NOT MUCH QPF.

MODELS HAVE BEEN FAIRLY CONSISTENT OVER THE LAST FEW RUNS SHOWING
THE COLD FRONT DROPPING SOUTH THROUGH WESTERN WASHINGTON WEDNESDAY
MORNING. THIS WILL END THE HEAVY PRECIPITATION IN THE MOUNTAINS AS
WELL AS CAUSE THE SNOW LEVEL TO DROP BACK DOWN TO NEAR 3000 FEET.
NOT MUCH IN THE WAY OF SHOWER ACTIVITY BEHIND THE THE FRONT. THERE
IS THE POSSIBILITY OF A PUGET SOUND CONVERGENCE ZONE BUT WITH THE
WINDS ALOFT THE CONVERGENCE ZONE WILL PROBABLY END UP GETTING PUSHED
INTO THE CASCADES. THIS WILL KEEP SOME PRECIPITATION GOING BETWEEN
STEVENS AND SNOQUALMIE PASS BUT WITH THE LOWERING SNOW LEVELS DO NOT
EXPECT THIS PRECIPITATION TO HYDROLOGICALLY SIGNIFICANT.

SHOWERS WILL COME TO AN WEDNESDAY NIGHT WITH A LITTLE BREAK IN THE
ACTION FOR THE LOWLANDS ON THURSDAY AS A WEAK UPPER LEVEL RIDGE
BUILDS INTO THE AREA AS WELL AS HIGH PRESSURE AT THE SURFACE.
TEMPERATURES ON THURSDAY WILL ACTUALLY BE COOLER EVEN WITH MORE
SUNSHINE THEN THE TEMPERATURES TODAY AND WEDNESDAY. FELTON

AVALANCHE INFO FROM THE PREV DISCUSSION...
ABOUT 2-3 FEET OF SNOWFALL WAS SEEN AT MOST SITES ON FRIDAY AND
SATURDAY. THIS NEW SNOW ACCUMULATED A VARIETY OF LAYERS INCLUDING
CRUSTS AND LOCAL HOAR FROST LAYERS FROM EARLIER IN FEBRUARY.
FATALITY ACCIDENTS OCCURRED AT STEVENS AND SNOQUALMIE ALONG WITH
OTHER CLOSE CALLS ON SATURDAY AND SUNDAY.

VERY STRONG WEST FLOW OVER THE FLAT OFFSHORE RIDGE SHOULD CARRY
MAJOR WARM FRONT MOISTURE TO THE OLYMPICS AND CASCADES ON TUESDAY
AND TUESDAY NIGHT. SEVERAL INCHES OF RAIN SHOULD BE SEEN AT MOST
SITES NEAR AND WEST OF THE CREST WITH SNOW LEVELS RISING TO THE
6-7000 FOOT RANGE FROM NORTH TO SOUTH IN THE CASCADES. THIS SHOULD
CAUSE AVALANCHES AT LEAST INVOLVING MOST OR ALL THE RECENT SNOW WITH
POTENTIAL WEAK LAYERS AND BED SURFACES PROVIDED BY THE HOAR FROST
AND CRUSTS. IN ANY CASE AVALANCHES COULD EASILY ENTRAIN MORE SNOW
RESULTING IN WIDESPREAD POTENTIAL LARGE AVALANCHES.

AN AVALANCHE WARNING HAS BEEN ISSUED FOR EXTREME AVALANCHE DANGER ON
TUESDAY NEAR AND WEST OF THE CREST AND A HIGH DANGER ELSEWHERE. THE
NWAC RECOMMENDS AVOIDING ALL AVALANCHE TERRAIN ON TUESDAY IN THE
OLYMPICS AND NEAR AND WEST OF THE CREST WITH TRAVEL IN AVALANCHE
TERRAIN NOT RECOMMENDED ELSEWHERE. PLEASE VISIT NWAC.US FOR DETAILS.
FERBER

.LONG TERM FROM THE PREV DISCUSSION...EXTENDED MODELS IN GOOD
AGREEMENT WITH ANOTHER FRONT MOVING INTO WESTERN WASHINGTON ON
FRIDAY BRINGING MORE RAIN TO THE AREA. COOL UPPER LEVEL TROUGH
SETTLING INTO THE PACIFIC NORTHWEST BEHIND THE FRONT LATER FRIDAY
NIGHT INTO SATURDAY. MODELS AGREE THE COLDEST AIR WILL REMAIN
BOTTLED UP OVER BRITISH COLUMBIA WITH THE JET WELL SOUTH OF THE
AREA. STILL...THE GFS HAS THE 1000-850 MB THICKNESS VALUES DROPPING
BELOW 1300 METERS SATURDAY WITH THE ECMWF VALUES JUST A TOUCH
HIGHER. WILL STAY WITH THE LOW SNOW LEVEL IDEA SATURDAY INTO
SATURDAY NIGHT. AIR MASS CONTINUES TO COOL ON SUNDAY WITH 1000-850
MB THICKNESS VALUES WELL BELOW 1300 METERS. CURRENT FORECAST HAS THE
SNOW LEVEL NEAR 500 FEET AND WILL STAY WITH THIS FORECAST GIVEN THE
CURRENT MODEL RUNS. AIR MASS STARTS TO MODERATE A LITTLE ON MONDAY
WITH DRIER NORTHERLY FLOW ALOFT AS THE UPPER LEVEL RIDGE WELL
OFFSHORE EARLY IN THE WEEKEND APPROACHES THE COAST. FELTON

&&

.HYDROLOGY FROM THE PREV DISCUSSION...
WITH THE WEST NORTHWESTERLY FLOW ALOFT THE CENTRAL CASCADES LOOK TO
BE THE PRECIPITATION BULLSEYE FOR THIS EVENT. SNOW LEVELS ARE STILL
AROUND 4000 FEET EARLY THIS MORNING BUT WITH THE WESTPORT PROFILER
SHOWING THE INCREASE IN THE WINDS ALOFT THE WARM ADVECTION SHOULD
START KICKING IN SOON WITH THE SNOW LEVELS RISING INTO THE 6000-7000
FOOT RANGE. PRECIPITATION RATES OVER THE MOUNTAINS WILL INCREASE
DRASTICALLY THIS MORNING. THERE ARE SOME SMALL DIFFERENCES IN THE
MODELS WITH THE NAM MOVING THE PRECIPITATION BULLSEYE OVER THE NORTH
CASCADES LATER TONIGHT WHILE THE GFS KEEPS THE HEAVIEST
PRECIPITATION FOCUSED ON THE CENTRAL CASCADES. THE MODELS ARE IN
GOOD AGREEMENT THAT THE COLD FRONT WILL MOVE THROUGH WEDNESDAY
MORNING BRINGING ABOUT AN END TO THE HEAVIER PRECIPITATION. HAVE
GONE WITH THE GFS SOLUTION IN THE QPF GRIDS THIS MORNING WITH STORM
TOTAL PRECIPITATION...FROM 12Z TODAY TO 18Z WEDNESDAY...BETWEEN
STEVENS AND SNOQUALMIE PASS IN THE 4 TO 6 INCH RANGE WITH HIGHER
AMOUNTS POSSIBLE. LESSER AMOUNTS TO THE NORTH AND SOUTH OF THIS AREA
WITH THE EXCEPT OF AROUND MOUNT RAINIER. EVEN OUTSIDE THE BULLSEYE 2
TO 4 INCHES OF RAIN IS FORECASTED.

THEREFORE THE RIVERS OF GREATEST RISK OF MAJOR FLOODING ARE THE ONES
FLOWING OUT OF KING AND SNOHOMISH COUNTIES...THE STILLAGUAMISH...
THE SKYKOMISH...THE TOLT...THE SNOHOMISH...AND THE SNOQUALMIE. OTHER
RIVERS WITH AT LEAST PART OF THEIR DRAINAGE IN KING AND SNOHOMISH
COUNTIES INCLUDE THE SKAGIT AND CEDAR RIVERS...AND THESE ALSO HAVE A
HIGH RISK OF FLOODING.

THERE STILL IS ENOUGH UNCERTAINTY THAT ALL RIVERS IN WESTERN
WASHINGTON HAVE SOME RISK OF FLOODING. A FLOOD WATCH HAS BEEN ISSUED
THAT COVERS ALL MAIN STEM RIVERS...INCLUDING THOSE ON THE OLYMPIC
PENINSULA AND ALSO THE ENTIRE CHEHALIS RIVER DRAINAGE AND IT WILL BE
CONTINUED WITH THIS FORECAST PACKAGE. EXPERIENCE HAS SHOWN THAT
DURING HEAVY RAINFALL EVENTS THE CONVEYOR BELT OF WARM MOIST AIR CAN
MOVE AROUND IN UNEXPECTED WAYS. STRONG WEST NORTHWESTERLY FLOW INTO
THE OLYMPICS FAVORS BIG RISES ON THE BOGACHIEL AND SATSOP
RIVERS...AS WELL AS ALL RIVERS ON THE WESTERN SLOPES OF THE OLYMPICS.

ONE FEATURE WORTH NOTING IS THAT STRONG FLOW ALOFT WILL ALSO INHIBIT
HEAVY RAIN DOWNSTREAM OF THE OLYMPICS...OVER THE LOWLANDS AROUND
PUGET SOUND INCLUDING SEATTLE AND TACOMA.

ANOTHER MODERATELY WET WEATHER SYSTEM IS EXPECTED TO MOVE THROUGH
THE AREA FRIDAY. HOWEVER...THIS WILL BE A MUCH COLDER SYSTEM
AND LIKELY MORE OF A MOUNTAIN SNOW PRODUCER VERSUS A RIVER FLOOD
THREAT. FELTON

&&

.AVIATION...WARM FRONTAL PRECIP WILL CONTINUE ACROSS WESTERN WA
TODAY. EXPECT RAIN AT TIMES WITH MVFR TO IFR CIGS...THE MOUNTAINS
WILL BE OBSCURED. THE CENTRAL SOUND MAY STAY RAIN SHADOWED WITH
WESTERLY FLOW OFF THE OLYMPICS. EXPECT GUSTY S/SW FLOW AT THE
SURFACE WITH GUSTS TO 30 KT POSSIBLE. LITTLE CHANGE IN THE
CONDITIONS TONIGHT. 33

KSEA...THE CENTRAL SOUND IS IN THE RAIN SHADOW THIS MORNING WITH
WESTERLY DOWNSLOPE FLOW OFF THE OLYMPICS. HOWEVER CIGS ARE STILL IN
MVFR RANGE WITH SHOWERS IN THE VICINITY. EXPECT SOUTH WINDS
21015G25KT TODAY. 33

&&

.MARINE...STRONG ONSHORE FLOW WILL CONTINUE ACROSS WESTERN WA TODAY.
THE STRONGEST WINDS WILL BE FOUND THROUGH THE STRAIT OF JUAN DE FUCA
WITH WEST WINDS INCREASING TO 30-40 KT. STRONG WEST TO NW WINDS MAY
ALSO SURGE INTO ADMIRALTY INLET TONIGHT. ELSEWHERE...SMALL CRAFT
ADVISORIES REMAIN IN EFFECT. HIGH PRES OVER THE OFFSHORE WATERS WILL
MAINTAIN ONSHORE FLOW ON WED...WITH GALES CONTINUING THROUGH THE
STRAIT. WINDS WILL WEAKEN ON THU AS HIGH PRES SHIFTS INLAND. ANOTHER
PAC SYSTEM WILL IMPACT WESTERN WA THU NIGHT INTO FRI. 33

&&
