AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SEATTLE WA
1113 AM PST SAT NOV 21 2009

.SYNOPSIS...A WEAK UPPER LEVEL RIDGE WILL MOVE OVER WESTERN
WASHINGTON THROUGH MIDDAY TODAY...FOLLOWED QUICKLY BY A VIGOROUS
FRONTAL SYSTEM THIS AFTERNOON AND EVENING BRINGING RAIN AND WINDY
CONDITIONS TO THE AREA INTO SUNDAY. HEAVY SNOW WILL FALL IN THE
MOUNTAINS WITH THE SNOW LEVEL REMAINING AT OR BELOW 3000 FEET. A
WEAKER FRONT WILL MOVE THROUGH THE AREA MONDAY AND MONDAY
NIGHT...AND ANOTHER WEAK FRONT WILL ARRIVE LATER IN THE WEEK.

&&

.SHORT TERM...NORTHWEST FLOW ALOFT OVER WESTERN WASHINGTON AND
LINGERING SCATTERED SHOWERS ACROSS THE AREA THIS MORNING. THE
FREEZING LEVEL HAS FALLEN TO AROUND 3000 FT. THE WEAK OFFSHORE RIDGE
WILL CONTINUE TO MOVE QUICKLY ACROSS WESTERN WASHINGTON THIS
MORNING...FOLLOWED BY THE SOUTH END OF AN OCCLUDED FRONT SWINGING
INTO BRITISH COLUMBIA BRINGING SIGNIFICANT PRECIPITATION TO THE THE
COAST AND OLYMPICS THIS AFTERNOON. A FRONTAL WAVE AND STRONG JET
WILL 45N/145W WILL DEEPEN AND MOVE THROUGH THE FORECAST AREA
TONIGHT.

HEAVY SNOW FOR THE MOUNTAINS REMAINS ON TRACK WITH IMPRESSIVE
PRECIPITATION AMOUNTS OVER THE OLYMPICS IN THE 3 TO 4 INCH RANGE AND
THE CASCADES IN THE 1 TO 3 INCH NEIGHBORHOOD THROUGH SUNDAY MORNING.
SNOW LEVELS RISE TO AROUND 3000 FT AS THIS FEATURE MOVES THROUGH...
WITH ROUGHLY TO 30 TO 40 INCHES OF SNOW EXPECTED FOR THE OLYMPICS
AND 10 TO 30 INCHES FOR THE CASCADES. EVEN THE RELATIVELY DRIER
HURRICANE RIDGE AREA SHOULD RECEIVE WINTER STORM WARNING
AMOUNTS...IE 12 INCHES IN 12 HOURS OR 18 INCHES IN 24 HOURS.

THE TRACK OF THE SURFACE LOW REMAINS ONE OF THE FORECAST CHALANGES
FOR THE DAY. THE MOST LIKELY SCENARIO REMAINS THAT IT WILL REACH THE
CENTRAL WASHINGTON COAST AROUND MIDNIGHT TONIGHT...MOVE NORTHEAST
ACROSS THE OLYMPIC PENINSULA AND INTO THE NORTH PART OF THE PUGET
SOUND REGION TO AROUND MT BAKER AT 4 AM AND THEN HEAD INTO BRITISH
COLUMBIA. IT WILL PRODUCE BREEZY TO WINDY CONDITIONS ACROSS THE
AREA. STONGEST WINDS WILL LIKELY BE WITH THE SOUTHERLIES AHEAD OF
THE LOW TONIGHT ESPECIALLY ALONG THE COAST AND NORTHWEST
INTERIOR...AND AGAIN WITH THE WESTERLIES SUNDAY MORNING THROUGH THE
EAST STRAIT INTO WHIDBEY ISLAND. FOR NOW HAVE ISSUED A HIGH WIND
WATCH FOR THE CENTRAL WASHINGTON COAST THROUGH THE CHEHALIS GAP AND
INTO THE SOUTHWEST INTERIOR FOR THE STRONG WESTERLIES WITH THE LOW
SUNDAY MORNING. IN ADDITION HAVE ISSUED A WIND ADVISORY FOR THE
NORTH INTERIOR...ADMIRALTY INLET...SAN JUANS AND EAST STRAIT FOR THE
SOUTHERLIES THIS AFTERNOON AND TONGITH FOLLOWED BY THE  WESTERLIES
WITH AND BEHIND THE LOW. WILL BE WATCHING EVOLUTION AND TRACK OF THE
LOW AS IT APPROACHES THE COAST THIS AFTERNOON. WINDS SHOULD BEGIN TO
COME DOWN BY LATE SUNDAY MORNING ALL AREAS.

POST-FRONTAL SHOWERS WILL TAPER OFF SUNDAY AFTERNOON EVENING AS  AN
UPPER RIDGE WILL MOVE OVERHEAD SUNDAY EVENING. THE RIDGE KICKS EAST
QUICKLY MONDAY AHEAD OF ANOTHER FRONTAL SYSTEM. THIS SYSTEM COULD
STILL BRING DECENT PRECIPITATION AMOUNTS TO THE COAST AND OLYMPIC
PENINSULA MONDAY AFTERNOON...BUT WEAKENS AS IT MOVES INLAND MONDAY
NIGHT. COMPARED TO LAST SEVERAL SYSTEMS THIS WILL BE AN UNEVENTFUL
SYSTEM...MARKING THE BEGINNING OF A PERIOD OF QUIETER WEATHER. COOK

.LONG TERM...FROM PREVIOUS DISCUSSION...A WEAK UPPER RIDGE WILL
FOLLOW THE FRONT THAT MOVES THROUGH MONDAY AND MONDAY NIGHT. THERE
IS JUST A CHANCE OF RAIN IN THE FORECAST FOR TUESDAY AND
WEDNESDAY...WITH A FAIRLY GOOD CHANCE FOR SOME DRY WEATHER OVER
THOSE TWO DAYS. A WEAK FRONT WILL SLOWLY MOVE ACROSS WESTERN
WASHINGTON WEDNESDAY NIGHT AND THURSDAY. ANOTHER FRONTAL WAVE WILL
PROBABLY KEEP THE AREA WET THURSDAY NIGHT AND FRIDAY...THOUGH
DISAGREEMENT BETWEEN MODELS DROPS OFF CONSIDERABLY BY LATE IN THE
WEEK. MCDONNAL

&&

.HYDROLOGY...TODAYS SYSTEM WILL BRING IMPRESSIVE AMOUNTS OF
PRECIPITATION TO THE CASCADES AND OLYMPICS...BUT RELATIVELY LOW SNOW
LEVELS WILL MITIGATE THE IMPACT ON RIVERS EXCEPT THE TWO RIVERS THAT
ARE ALREADY CLOSE TO OR ABOVE FLOOD STAGE -- THE SKOKOMISH AND THE
LOWER REACH OF THE CHEHALIS IN GRAYS HARBOR COUNTY. THE SNOW LEVEL
WILL ONLY RISING TO AROUND 3000 FT...MAKING THIS MOSTLY A MOUNTAIN
SNOW EVENT AND NOT A RAIN EVENT.

THE SKOKOMISH RIVER HAS FALLEN TO NEAR OR JUST BELOW FLOOD STAGE AT
THIS TIME...NEW FORECAST GUIDANCE SHOWS THE RIVER RISING AGAIN TO
JUST BELOW 17 FEET BY EARLY SUNDAY MORNING. IN ADDITION...THERE WILL
BE A PLANNED RELEASE OF 3000 CFS FROM CUSHMAN DAM #2 INTO THE NORTH
FORK SKOKOMISH RIVER THIS AFTERNOON. ACCORDINGLY WILL EXTEND THE
WARNING FOR THE SKOKOMISH INTO MONDAY.

A FLOOD WATCH REMAINS IN EFFECT FOR THE LOWER REACH OF THE CHEHALIS
RIVER IN GRAYS HARBOR COUNTY...WHICH HAS BEEN WITHIN A FOOT OF FLOOD
STAGE FOR THE PAST TWO DAYS. IT REMAINS CONCEIVABLE THAT THE
PRECIPITATION FROM THE INCOMING SYSTEM COULD HELP FINALLY NUDGE THE
LOWER CHEHALIS ABOVE FLOOD STAGE. IF FLOODING DOES OCCUR IT WILL BE
MINOR.

THE NEXT SYSTEM ON MONDAY LOOKS TO BE PROGRESSIVE ENOUGH AND WEAK
ENOUGH TO BE OF LITTLE CONCERN WITH RESPECT TO FLOODING. THE AIR
MASS OVER THE NORTHWEST FOR THE REMAINDER OF THE WEEK WILL BE WARMER
WITH HIGHER SNOW LEVELS...HOWEVER THE SYSTEMS THAT ARE EXPECTED TO
AFFECT THE AREA WILL BE FAIRLY WEAK AND ARE NOT EXPECTED TO CAUSE
ANY ADDITIONAL FLOODING CONCERNS.

NO FLOODING IS EXPECTED AT ANY TIME ON THE GREEN RIVER. COOK

&&

.AVIATION...A WARM FRONT WILL SPREAD RAIN INTO WRN WA THIS AFTERNOON
THROUGH TONIGHT. SW FLOW ALOFT WILL INCREASE THROUGH THE DAY AND
BECOME STRONG SLY FLOW BY THIS EVENING. THE ATMOSPHERE WILL REMAIN
MOIST AND STABLE.

A STRONG SURFACE LOW WILL DEVELOP OFFSHORE TODAY AND
TONIGHT...REACHING THE S OR CENTRAL WA COAST BY 12Z SUN MORNING AS A
POTENTIAL 985 MB LOW. THIS WILL BRING STRONG SLY FLOW ALOFT AND AT
THE SURFACE...SHIFTING WLY AFTER 12Z AS THE LOW TRACKS INLAND NEAR
KHQM...PROBABLY TRACKING JUST SOUTH OF KOLM. HOWEVER...THE TRACK IS
UNCERTAIN AT THIS TIME WITH SOME MODELS SHOWING A MORE NORTHERN
SOLUTION.

KSEA...SLY WINDS 8-15 KT TODAY...BECOMING MORE ELY TONIGHT. THERE
WILL BE A POTENTIAL FOR LLWS BETWEEN 03Z AND 12Z SUN DUE TO ELY
WINDS AT THE SFC AND STRONG SLY WINDS NEAR 2K FT. CONFIDENCE IS
STILL LOW BUT MAY WILL MONITOR AND IF NEEDED UPDATE THE TAF PRIOR TO
THE 00Z ISSUANCE. LATEST 12Z MODEL SOLUTIONS CONTINUE TO VARY
CONSIDERABLE REGARDING THE TRACK AND DEPTH OF A SURFACE LOW NOW
EXPECTED TO AFFECT THE AREA. WINDS WILL INCREASE DRAMATICALLY FROM
THE SW SOMETIME BETWEEN 12Z AND 15Z. CONCERNING CIGS...ANTICIPATE
CIGS TO GRADUALLY LOWER DURING THE DAY...ALTHOUGH THERE WILL BE
OCCASIONAL CIGS NEAR 2500 FT THIS MORNING. BY LATE THIS
EVENING...CIGS SHOULD BE NEAR 2K FT...WITH RAIN AND FOG REDUCING
VSBYS INTO THE 3-5SM RANGE. DTM

.MARINE...WINDS WILL PICK UP ALONG THE COAST BY MIDDAY AND ACROSS
THE INLAND WATERS DURING THE AFTERNOON AS A WARM FRONT REACHES
WESTERN WASHINGTON. LATEST MODELS SHOW GALES TO DEVELOP WITH THIS
INITIAL FRONT FROM AROUND THE E ENTRANCE/ADMIRALTY INLET NWD AND
ALSO THE COASTAL WATERS. WIND ADVISORY FOR THE SOUND STILL LOOKS
GOOD.

A POTENTIALLY STRONG 985 MB SURFACE LOW WILL ENTER THE COASTAL
WATERS AFTER 09Z TONIGHT AND TRACK INTO THE CENTRAL/S WA COAST
AROUND 12Z. WINDS BEHIND THE FRONT WILL RISE DRASTICALLY SO I UPPED
THE WINDS TO HIGH END GALE AND EXTENDED THE WARNING THROUGH SUN
MORNING. DEPENDING ON THE EXACT TRACK...STORM FORCE WINDS COULD BE
POSSIBLE ACROSS THE CENTRAL/S WA COASTAL WATERS. WILL EVALUATE THIS
POSSIBILITY BEFORE THE AFTERNOON COASTAL FORECAST ISSUANCE. DTM
