AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SEATTLE WA
900 PM PDT MON MAR 28 2011

.SYNOPSIS...A FRONTAL SYSTEM WILL REACH THE AREA TONIGHT WITH
ANOTHER ROUND OF RAIN FOR THE AREA. THERE WILL BE A VERY BRIEF LULL
IN SHOWER ACTIVITY TUESDAY BEFORE THE NEXT SYSTEM ARRIVES. THIS NEXT
STRONGER FRONTAL SYSTEM WILL STALL OVER THE REGION WEDNESDAY AND
THURSDAY...FOR POTENTIALLY HEAVY RAIN IN THE MOUNTAINS. THE PATTERN
WILL BECOME MORE SHOWERY BY THE END OF THE WEEK.

&&

.SHORT TERM...A COLD FRONT WILL BRING RAIN TONIGHT...CHANGING TO
SHOWERS TUESDAY MORNING. AFTER A BRIEF BREAK...A WARM FRONT WILL
BRING MORE...AND HEAVIER RAINS TUESDAY NIGHT AND WEDNESDAY. MODELS
SUGGEST THERE WILL BE A BIT OF A LULL LATER WEDNESDAY THEN ANOTHER
SURGE OF MOISTURE WILL INCREASE RAINS OVER THE AREA WEDNESDAY NIGHT
AND THURSDAY. ALL IN ALL THE NEXT THREE DAYS LOOK PRETTY WET...MORE
LIKE LATE NOVEMBER THAN LATE MARCH.

SNOW LEVELS WILL BE LOW ENOUGH WITH THE SYSTEM TONIGHT TO BRING SNOW
TO THE PASSES. A WINTER WEATHER ADVISORY IS IN EFFECT FOR THIS. SNOW
LEVELS WILL RISE WELL ABOVE PASS LEVELS TUESDAY NIGHT THROUGH
THURSDAY...ENDING THE MOUNTAIN SNOW THREAT...BUT INCREASING THE
RIVER FLOODING THREAT. SEE THE HYDROLOGY SECTION BELOW FOR MORE
DETAILS. NO UPDATES PLANNED THIS EVENING. SCHNEIDER

.LONG TERM...PREVIOUS DISCUSSION...OUR WET AND ACTIVE PERIOD MAY
STRETCH INTO FRI AS THE FLOW ALOFT REMAINS NEARLY ZONAL. THEN ON
SAT...MODELS SHOW A SHORT WAVE TROUGH PASSING THROUGH...RESULTING IN
MORE SHOWERS. WE MAY SEE A BRIEF RESPITE BY SUNDAY AS THE FLOW ALOFT
BECOMES MORE NWLY...THANKS TO A RIDGE BUILDING OFFSHORE. WILL
PROBABLY STILL SEE A FEW SHOWERS IN THE CASCADES BUT TOTAL QPF
AMOUNTS ARE NOT HEAVY...WITH JUST A FEW SHOWERS IN THE LOWLANDS. THE
RIDGE AXIS MAY SHIFT INLAND ON MON...BUT THERE IS ANOTHER WARM FRONT
RIGHT ON OUR DOORSTEP. THIS SYSTEM MAY SPREAD MORE RAIN TO THE
REGION MON AFTERNOON OR EVENING...DEPENDING ON THE MODEL. DUE TO
TIMING DIFFERENCES IN THE MODELS WILL STICK WITH A PERSISTENCE
FORECAST...NUDGED TOWARD CLIMO. 33

&&

.HYDROLOGY...PREVIOUS DISCUSSION...RAIN TONIGHT AND TUESDAY WILL NOT
CAUSE ANY FLOODING. AMOUNTS ARE LIGHT AND THE SNOW LEVEL WILL BE
RELATIVELY LOW...3000 FEET. HOWEVER THE SATELLITE SHOWS A VERY MOIST
LOOKING SYSTEM EMBEDDED IN A WESTERLY JET HEADED RIGHT FOR THE
PACIFIC NORTHWEST OUT BEYOND 150W. THIS COULD BE A CONCERN LATER IN
THE WEEK.

THE EURO AND GFS STILL DISAGREE. THE EURO BRINGS A SOLID 24 HOURS OF
HEAVY RAIN TO THE OLYMPICS 00Z WEDNESDAY TO 00Z THURSDAY AND HAS
SIGNIFICANT RAINFALL FOR ANOTHER 24 HOURS AFTER THAT. THAT SOLUTION
WOULD CAUSE RIVERS IN THOSE AREAS TO RISE SHARPLY AND THE MOST FLOOD
PRONE RIVERS...SUCH AS THE SKOKOMISH AND SNOQUALMIE...MIGHT EVEN GET
TO FLOOD STAGE. THE GFS BRINGS A FAIR AMOUNT OF RAIN TO THE OLYMPICS
AND NORTH CASCADES TUESDAY NIGHT AND WEDNESDAY BUT AFTER THAT THERE
IS A LONG LULL...12-18 HOURS...WITH LITTLE RAIN. THE GFS BRINGS A
FINAL BURST OF RAIN THURSDAY AFTERNOON AND EVENING. THIS SOLUTION IS
LESS THREATENING AND THE QPF FORECAST HAS LEANED TOWARD IT. HOWEVER
THE UNCERTAINTY IS ENOUGH TO WARRANT A FLOOD POTENTIAL OUTLOOK WHICH
WILL GO OUT THIS AFTERNOON.

FLOODING ON THE GREEN RIVER IS UNLIKELY OVER THE NEXT 10 DAYS. BURKE

.AVIATION...A COLD FRONT OVER THE COASTAL WATERS AT 03Z WILL MOVE
ACROSS PUGET SOUND 09Z-12Z. LOW LEVEL WINDS FL050-FL100 WILL BE SSW
40 KT 06Z VEERING TO WSW BY 12Z...THEN EASING. MODERATE W FLOW ALOFT
ABOVE FL100 WILL BECOME NW BEHIND THE FRONT. LOW LEVEL MOISTURE IS
ALREADY INCREASING ACROSS W WA AHEAD OF THE FRONT AS AREAS OF RAIN
SPREAD INLAND. CIGS WILL LOWER TO OVC020-030.

MODEST IMPROVEMENT TO BKN-OVC030-050 IS EXPECTED AFTER 18Z. RAIN
FROM THE NEXT FRONTAL SYSTEM WILL SPREAD INLAND BY 00Z.

KSEA...CIGS BKN-OVC025-035 THROUGH 07Z MAY END UP DROPPING A LITTLE
LOWER TO OVC020-025 AS THE FRONT MOVES OVERHEAD AROUND 12Z. LOW
LEVEL WINDS FL050-FL100 WILL BE SSW 40 KT 06Z VEERING TO WSW BY
12Z...THEN EASING. SURFACE WINDS WILL REMAIN S 5-10 KT...NO WIND
SHIFTS EXPECTED. KAM

&&

.MARINE...COLD FRONT OVER THE COASTAL WATERS AROUND 03Z WILL MOVE
INLAND ACROSS PUGET SOUND 09Z-12Z. NEW 00Z NAM IS A LITTLE FASTER
THAN THE 18Z GFS BUT THE DIFFERENCE IS NOT SIGNIFICANT. SMALL CRAFT
ADVISORIES WILL REMAIN UP FOR MOST AREAS...BUT SO FAR SCA WINDS HAVE
BEEN SPOTTY. STRONGEST WINDS SHOULD BE JUST AHEAD OF THE FRONT LATE
TONIGHT THEN EASING BY 15Z. MOST ADVISORIES EXTEND THROUGH TUESDAY
MORNING SO WILL SEE WHAT THE 00Z GFS/WRF-GFS INDICATE THEN LOOK AT
ADJUSTMENTS ON THE 3 AM FORECAST.

ANOTHER FRONTAL SYSTEM APPROACHES THE AREA TUESDAY NIGHT. MODELS
SHOW SCA S WINDS AHEAD OF THE FRONT...BUT STRONG ONSHORE FLOW
DEVELOPING WEDNESDAY MORNING BEHIND THE FRONT COULD GENERATE GALES
IN THE STRAIT. A GALE WATCH WILL REMAIN IN EFFECT FOR THAT.

A WEAK SURFACE TROUGH MAY CROSS THE AREA THURSDAY MORNING FOLLOWED
BY A SOMEWHAT STRONGER FRONT FRIDAY MORNING. KAM

&&

.AVALANCHE...PREVIOUS DISCUSSION...GRADUALLY INCREASING AMOUNTS OF
RECENT SNOW BECOMING WET AND WEAK WITH DAYTIME WARMING OR
SUNSHINE...BOTH OF WHICH MAY HAVE CONTRIBUTED TO AVALANCHE FATALITY
OF SNOWBOARDER SUNDAY PM WEST OF STEVENS PASS. WHILE SAD AND VERY
SERIOUS...THE UPCOMING WARMING AND HEAVY RAIN OR SNOW ANTICIPATED
LATE TUESDAY AND WEDNESDAY WILL HAVE A BROADER IMPACT. REMEMBER THAT
WE HAVE HAD FROM ABOUT 7 TO 15 FEET OF SNOW IN MARCH...ALL AT LOW
FREEZING LEVELS WITH NO SIGNIFICANT RAIN EVENTS TO STABILIZE. WITH
FORECAST MODELS INDICATING PROLONGED WARMING EVENT AND PERIODS OF
HEAVY PRECIPITATION TUESDAY NIGHT INTO WEDNESDAY AND BEYOND...THE NW
SNOWPACK SHOULD BE STRONGLY AND NEGATIVELY AFFECTED WITH HIGH DANGER
DESCENDING TO LOW ELEVATIONS. HEAVY RAIN OR WET DENSE SNOW SHOULD
LOAD...WET..OR WEAKEN THE LARGE AMOUNTS OF SNOW AND PRODUCE ABUNDANT
NATURAL AVALANCHES ALONG WITH INCREASING POTENTIAL FOR ISOLATED
LARGE EVENTS. BACK COUNTRY TRAVELERS WOULD DO WELL TO PLAN SPRING
ACTIVITIES AT HOME ON WEDNESDAY RATHER THAN VENTURE INTO AVALANCHE
TERRAIN...WITH EVEN RELATIVELY FLAT AVALANCHE PATH RUNOUTS POSSIBLY
IMPACTED BY NEW DEBRIS. MOORE

&&

.SEW WATCHES/WARNINGS/ADVISORIES...

WA...WINTER WEATHER ADVISORY IN EFFECT FROM 11 PM TONIGHT THROUGH
     5PM PDT TUE FOR THE CASCADES.

     AVALANCHE WATCH FOR LATE TUESDAY INTO WEDNESDAY FOR CASCADES
     AND OLYMPICS.

PZ...SMALL CRAFT ADVISORY ALL WATERS EXCEPT CENTRAL STRAIT.
     SMALL CRAFT ADVISORY FOR ROUGH GRAYS HARBOR BAR.
     GALE WATCH CENTRAL STRAIT AND EAST ENTRANCE WEDNESDAY AFTERNOON.
