AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE SEATTLE WA
1017 AM PST SUN DEC 14 2008

UPDATED THE AVIATION AND MARINE SEGMENTS.

.SYNOPSIS...STRONG HIGH PRESSURE OVER BRITISH COLUMBIA WILL PUSH
COLD ARCTIC AIR INTO WESTERN WASHINGTON THROUGH EARLY NEXT WEEK.
SNOW SHOWERS WILL PRODUCE ANOTHER INCH OR TWO OF SNOW TODAY.
WINDY CONDITIONS...ESPECIALLY IN THE NORTH INTERIOR...WILL ACCOMPANY
THE COLD AIR. BITTERLY COLD WEATHER WILL CONTINUE NEXT WEEK WITH
ANOTHER CHANCE OF SNOW ON WEDNESDAY.

&&

.SHORT TERM...THE BIG STORY FOR THE NEXT WEEK OR MORE WILL BE WELL
BELOW TEMPERATURES WITH MODIFIED ARCTIC AIR MAKING IT INTO WESTERN
WASHINGTON TONIGHT THROUGH TUESDAY...THEN AGAIN THURSDAY THROUGH
NEXT WEEKEND.

FORECASTING DETAILS OVER THE PAST FEW DAYS HAS BEEN DIFFICULT TO
NEAR IMPOSSIBLE. LOOKS TO BE MUCH OF THE SAME TODAY.

SNOW FELL EVERYWHERE OVERNIGHT WITH WHAT APPEARS TO BE 1-2 INCHES
SEATTLE SOUTHWARD AND ALONG THE CENTRAL COAST...AND 2-5 INCHES
EVERETT NORTHWARD TO NEAR BELLINGHAM THEN WEST TO AROUND FORKS.
WHILE ARCTIC OUTFLOW CONTINUES OVER THE FAR NORTH INTERIOR
TODAY...AN UPPER LEVEL LOW AND HAS DEVELOPED OFF VANCOUVER ISLAND
AND A 1000 MB SURFACE REFLECTION IS SITTING OFF THE N WA COAST. THIS
FEATURE IS DROPPING ONLY VERY SLOWLY SOUTH PER SATELLITE IMAGERY.
EASTERLY FLOW INDUCED BY OFFSHORE DEVELOPMENTS HAS FORMED A
MESOSCALE LOW NEAR WHIDBEY ISLAND THAT HAS PULLED SELY WINDS THROUGH
THE ADMIRALTY INLET AREA AND HAS PRODUCED LOCALLY GUSTY EAST WINDS
20 MPH GUST 35 MPH IN THE EAST PUGET SOUND LOWLANDS. SNOW SHOWERS
ARE PIVOTING AROUND THE N AND W SIDE OF THE NORTH INTERIOR MESOLOW.
THE 12Z NAM KEEPS SNOW SHOWER ACTIVITY MAINLY WEST OF THE SEATTLE
EVERETT AREA IN AN AREA FROM VICTORIA BC-WHIDBEY ISLAND SW INTO THE
OLYMPICS THIS MORNING. HOWEVER SATELLITE AND RADAR SHOWS A BLOB OF
MOISTURE AND SNOW MOVING NE AROUND THE SLOWER MOVING UPPER LOW
TOWARD THE SW INTERIOR AND PUGET SOUND AREA. NO GOOD RADAR DATA ON
THE COAST...BUT IT APPEARS THAT THIS SNOW WILL WORK ITS WAY UP THERE
AS WELL. WE WILL EXTEND THE WINTER WEATHER ADVISORY TO INCLUDE ALL
LOWLAND ZONES FOR AN ADDITIONAL INCH OR TWO...AND WILL KEEP IT GOING
THRU THE DAY TODAY.

WILL MAINTAIN THE MARGINAL WIND ADVISORY FOR EAST WINDS THROUGH
TONIGHT FOR THE EAST PUGET SOUND LOWLANDS. A WIND ADVISORY WILL
CONTINUE THROUGH 4 AM MON FOR WESTERN WHATCOM COUNTY AND THE SAN
JUAN ISLANDS AS WELL AS ARCTIC OUTFLOW CONTINUES.

ONCE THE OFFSHORE LOW DROPS SOUTH TO THE CENTRAL AND SOUTH
WASHINGTON COASTS LATE TODAY...EXPECT PRES GRADIENTS TO RESUME A
MORE NELY DIRECTION. CONDITIONS WILL ALSO GRADUALLY DRY AND SKIES
WILL SCATTER OUT FROM THE NORTH. TEMPERATURES SHOULD IN MOST AREAS
REMAIN BELOW FREEZING TODAY...THEN IT WILL GET QUITE COLD EVERYWHERE
TONIGHT THROUGH TUESDAY NIGHT AS A CHUNK OF ARCTIC HIGH PRES
GRADUALLY SAGES SE INTO EASTERN WA.

CURRENT FORECASTS GENERALLY LOOK GOOD BUT WILL MAKE UPDATES FOR
FIRST PERIOD MESOSCALE FEATURE STRENGTH AND MOVEMENT AND FOR
HEADLINE ADJUSTMENTS. ALBRECHT

.LONG TERM...PREVIOUS LONG RANGE DISCUSSION FOLLOWS...INTERESTING
PATTERN SETTING UP FOR THE MIDDLE OF THE WEEK. EXTENDED MODELS HAVE
BEEN FAIRLY CONSISTENT IN DEVELOPING A SHORTWAVE IN THE NORTHERLY
FLOW ON WEDNESDAY. THE 00Z RUNS ARE NO EXCEPTION. EARLIER EURO RUNS
WERE A LITTLE FURTHER OFFSHORE WITH THE SHORTWAVE DEVELOPMENT BUT
BOTH THE EURO AND GFS 00Z RUNS HAVE THE SHORTWAVE MOVING THROUGH
WESTERN WASHINGTON ON WEDNESDAY. THIS HAS THE POTENTIAL TO BRING A
FEW INCHES OF SNOW TO WESTERN WASHINGTON WEDNESDAY AND WEDNESDAY
NIGHT. SOME DIFFERENCES IN HOW FAST THE SYSTEM WILL KICK OUT OF
WESTERN WASHINGTON ON THURSDAY WITH THE GFS DRYING THINGS OUT FASTER
THAN THE EURO. NOT ENOUGH CONFIDENCE AT THIS POINT TO TAKE THE POPS
OUT OF THURSDAY. MORE COLD AIR SPILLING OUT OF SOUTH BRITISH
COLUMBIA BEHIND THE SHORTWAVE CONTINUING THE COLD SNAP INTO NEXT
WEEKEND. ANOTHER ROUND OF STRONG OUTFLOW WINDS IS POSSIBLE FOR THE
NORTH INTERIOR LATE IN THE WEEK. FELTON

&&

.AVIATION...A COLD...UPPER LOW W OF VANCOUVER ISLAND WILL CONTINUE
MOVING S. BY EARLY MON...THIS FEATURE WILL BE OFF THE SRN OREGON
COAST. SLY FLOW ALOFT BECMG MORE ELY WITH TIME. ELY LOW LEVEL FLOW
WILL BECOME MORE NLY LATER TODAY AND TONIGHT. MEANWHILE...SNOW
SHOWERS WILL CONTINUE TO PLAGUE THE AREA TODAY BEFORE WINDING DOWN
THIS EVENING. ANTICIPATE CIGS TO BE MAINLY IN THE 4-6K FT RANGE
EXCEPT NEAR 1K FT WITH THE SNOW SHOWERS. THE CLOUDS ARE ANTICIPATED
TO BECOME SCATTERED OVERNIGHT.

KSEA...THE FORECAST WILL CONTINUE TO BE A CHALLENGE DUE TO THE
COMPLICATED PATTERN THAT WE ARE PRESENTLY UNDER. PREVIOUS THINKING
WAS THAT THE THREAT OF SNOW SHOWERS WOULD END THIS AFTERNOON BUT
NOW IT DOES NOT APPEAR THAT WAY. THE UPPER LOW TO OUR NW WILL
CONTINUE TO BRING MOISTURE UP FROM THE S. THUS EXPECT LIGHT SNOW TO
REDEVELOP BY 20Z. THE CURRENT TAF HAS VISIBILITIES DROPPING TO 3SM
IN LIGHT SNOW...HOWEVER THERE IS A POSSIBILITY THAT THE VISIBILITY
COULD OCCASIONALLY DROP A LOW AS 3/4SM. THE POTENTIAL ALSO EXISTS
FOR ANOTHER INCH OF SNOW BY EARLY THIS EVENING. EXPECT CLEARING TO
OCCUR TONIGHT. MEANWHILE...GUSTY E WINDS WILL BECOME MORE NLY THIS
AFTERNOON.

THIS PORTION OF THE FORECAST DISCUSSION WILL BE UPDATED AS
NEEDED.

&&

.MARINE...A 1050 MB HIGH OVER FAR NORTHERN BRITISH COLUMBIA AND A
1002 MB LOW OFF THE WASHINGTON COAST WAS RESULTING IN EASTERLY FLOW
ACROSS THE AREA THIS MORNING. THE FLOW WILL BECOME NE LATER TODAY
AND TONIGHT AS THE SURFACE LOW MOVES OVER THE OREGON WATERS...AND THE
HIGH OVER FAR NORTHERN BRITISH COLUMBIA DROPS S. EXPECT STRONG AND
COLD NORTHERLY FLOW TO PERSIST OVER THE AREA THROUGH MON.

&&

.SEW WATCHES/WARNINGS/ADVISORIES...
WA...WINTER WEATHER ADVISORY FOR ALL WESTERN WASHINGTON LOWLAND
     ZONES TODAY.

     WIND ADVISORY FOR WESTERN WHATCOM COUNTY...THE SAN JUANS...AND
     THE EAST PUGET SOUND LOWLANDS THROUGH TONIGHT.

PZ...GALE WARNING IN EFFECT FOR THE COASTAL WATERS FROM CAPE
     FLATTERY TO JAMES ISLAND OUT TO 60 NM...WESTERN AND
     CENTRAL STRAIT OF JUAN DE FUCA...AND THE NORTHERN INLAND WATERS.

     SMALL CRAFT ADVISORY IN EFFECT FOR THE REMAINING WATERS.
