AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SEATTLE WA
945 AM PST TUE NOV 15 2011

.SYNOPSIS...MOIST NORTHWEST FLOW ALOFT WILL KEEP SCATTERED SHOWERS
GOING ACROSS THE CASCADES AND THE CONVERGENCE ZONE IN WESTERN
WASHINGTON THROUGH THE DAY.  A VIGOROUS FRONTAL SYSTEM WILL ARRIVE
WEDNESDAY BRINGING RAIN...SNOW CASCADES AND WIND TO THE REGION.  A
COLD UPPER TROUGH WILL SETTLE OVER THE PACIFIC NORTHWEST THURSDAY
AND FRIDAY WITH SHOWERS AND SNOW LEVELS DOWN TO 500 FEET.  THE NEXT
FRONTAL SYSTEM WILL BRUSH WASHINGTON OR POSSIBLY BYPASS THE AREA
OVER THE WEEKEND.  BY EARLY NEXT WEEK...THE WEATHER PATTERN WILL
BECOME UNSETTLED ONCE AGAIN.

&&

.SHORT TERM...SKIES HAVE CLEARED ACROSS A SIGNIFICANT PORTION OF THE
WESTERN WASHINGTON LOWLANDS IN RESPONSE TO SOME DRIER AIR MOVING
INTO THE REGION.  THE NORTHWESTERLY FLOW IS STRONG AND MOIST ENOUGH
HOWEVER THAT THE MOUNTAINS ARE ENVELOPED IN CLOUDS WITH SOME SHOWERS
AND THERE IS STILL RESIDUAL CONVERGENCE ZONES OVER THE EASTERN
PORTIONS OF THE SOUND.  THERE WILL BE SOME CUMULUS DEVELOPMENT
TODAY...BUT OVERALL THE DRYING TREND WILL CONTINUE THROUGH THE DAY
FOR A NICE DAY...BEFORE THE STORM.

A STRONG FRONTAL SYSTEM IS EXPECTED TO MOVE ACROSS THE LATER
WEDNESDAY.  RAIN AHEAD OF THE WARM FRONT WILL LIKELY REACH THE COAST
AROUND DAWN WEDNESDAY THEN SPREAD INLAND THROUGH THE MORNING.  THE
FRONT WILL SET-UP A RATHER STRONG EAST-SOUTHEAST GRADIENT DURING THE
DAY FOR AN INCREASE IN WIND IN CERTAIN AREAS OF WESTERN WASHINGTON.
STRONG WINDS WILL DEVELOP ALONG THE COAST FIRST EARLY WEDNESDAY
MORNING AND THEN INCREASE ALONG THE STRAIT OF JUAN DE FUCA AND FROM
THE ADMIRALTY INLET AREA NWD DURING THE MID-LATE MORNING HOURS. THE
NAM AND MM5 SUGGEST WIND ADVISORY CRITERIA IS LIKELY FOR THESE AREAS
WITH SE WINDS 25-35 MPH AND GUSTS TO 50 MPH.  WILL HAVE TO WATCH THE
LAKE LAWRENCE AREA IN EASTERN THURSTON COUNTY AS THAT LOCATION CAN
BE PRONE TO LOCALLY HIGH WINDS IN THESE SOUTHEAST WARM FRONTAL WIND
SCENARIOS.  WINDS WILL BE SLOWER TO PICK UP ACROSS THE GREATER PUGET
SOUND REGION AND THE SW INTERIOR...JUST AHEAD OF AND BEHIND THE COLD
FRONT WEDNESDAY NIGHT AND EARLY THURSDAY.  WINDS HERE COULD STILL
REACH THE 20 TO 30 MPH RANGE WITH HIGHER GUSTS.

THE OTHER CONCERN IS SNOW IN THE MOUNTAINS AND A POSSIBLE SLOPPY MIX
OF PRECIPITATION IN THE PASSES.  FOR THE OLYMPICS THE SNOW LEVEL
WILL RISE QUICKLY THROUGH THE DAY WHICH WILL GREATLY LIMIT THE
AMOUNT OF SNOW ACCUMULATION...GENERALLY BELOW ADVISORY CRITERIA FOR
THE AREA OF CONCERN...HURRICANE RIDGE.

FOR THE CASCADES SNOW LEVELS WILL START OFF LOW WEDNESDAY...PROBABLY
BELOW 2000 FEET.  THE PRECIPITATION IS EXPECTED TO BECOME RATHER
HEAVY THROUGH THE AFTERNOON HOURS WHILE THE SNOW LEVEL WILL BE SLOW
TO RISE DUE TO THE STRONG EASTERLY FLOW ACROSS THE CASCADES.  THIS
SHOULD DELAY THE CHANGE TO RAIN IN THE CENTRAL CASCADES PASSES LONG
ENOUGH TO GET A DECENT AMOUNT OF SNOW ACCUMULATION.  FOR SNOQUALMIE
PASS...THE SNOW SHOULD CHANGE TO RAIN BY/DURING THE EARLY EVENING
LEAVING THE PASS IN ADVISORY AMOUNTS.  STEVENS PASS WILL LIKELY HOLD
OUT LONGER POSSIBLY HITTING WARNING AMOUNTS.  DEPENDING ON WHERE THE
TRIPLE POINT OF THE SYSTEM PASSES ACROSS THE MOUNTAINS...STEVENS HAS
THE POTENTIAL TO STAY SNOW OR AT LEAST A MIX.  THE VOLCANOES ARE
EXPECTED TO GET SIGNIFICANTLY MORE SNOW AND THE NORTH CASCADES WILL
LIKELY STAY SNOW BELOW ABOUT 4000 FEET THROUGH THE EVENT.  SNOW
LEVELS WILL FALL AGAIN AFTER THE COLD FRONT PASSES ACROSS THE REGION
LATER WEDNESDAY NIGHT AND SHOULD BE BELOW 3000 FEET BY THURSDAY
MORNING.  WITH THE UNCERTAINTY AND POTENTIAL FOR SOME SIGNIFICANT
SNOWS...DECIDED ON ISSUING A WINTER STORM WATCH FOR THE CASCADES.

FOR THURSDAY...A DEEP UPPER LOW WILL START MOVING SOUTHEAST OUT OF
THE GULF OF ALASKA WITH PLENTY OF SHOWER ACTIVITY ACROSS THE AREA AS
A RESULT.  THIS WILL PRIMARILY IMPACT THE MOUNTAINS BUT EVERY
LOCATION IN WESTERN WASHINGTON IS UNDER THE GUN.  SNOW LEVELS WILL
BE LOW...DOWN AROUND 1500 FEET SO THE SHOWERS WILL BE SNOW ACROSS
THE PASSES WITH SEVERAL INCHES EXPECTED.  CERNIGLIA

.LONG TERM...FROM PREVIOUS DISCUSSION...A DEEP COLD TROUGH WILL
DEVELOP OVER THE SRN B.C. COAST ON THURSDAY NIGHT AND DRIVE SWD
THROUGH THE AREA ON FRIDAY. THIS WILL USHER IN EVEN COLDER AIR FROM
CANADA CAUSING SNOW LEVELS TO FALL TO AT LEAST 1000 FEET DURING THE
DAY...AND POSSIBLY DOWN TO 500 FEET OR LOCALLY TO SEA-LEVEL WITH
HEAVIER SHOWERS OR ANY CONVERGENCE ZONES. IT IS STILL TOO FAR OUT TO
BE TALKING ABOUT ANY LOWLAND SNOW ACCUMULATIONS. HOWEVER...CURRENT
MODELS SUGGEST ANY ACCUMULATIONS WOULD LIKELY BE HIGHLY LOCALIZED.
THE BIGGER STORY WILL BE THE COLDER TEMPERATURES ACROSS THE AREA.
HIGH TEMPS FRIDAY AND OVER THE WEEKEND WILL STRUGGLE TO GET OUT OF
THE 30S IN SOME COLDER AREAS ESPECIALLY UP NORTH. THE COLDEST LOW
TEMPERATURES SO FAR THIS SEASON ARE ALSO POSSIBLE SATURDAY AND
SUNDAY MORNINGS.

THE NEXT SYSTEM TO APPROACH THE AREA OVER THE WEEKEND IS LIKELY TO
JUST BRUSH WRN WA OR POSSIBLY BYPASS THE AREA ALL TOGETHER.
CONFIDENCE IS TOO LOW TO REMOVE POPS GIVEN THAT A SYSTEM WILL BE
NEAR THE WA COAST DROPPING SWD. ANY SUBTLE SHIFT EWD COULD LEAD TO
SOME LIGHT RAIN ACROSS THE AREA...ESPECIALLY W OF PUGET SOUND.

LONG RANGE MODELS ARE SHOWING A RETURN TO AN ACTIVE WEATHER PATTERN
BY EARLY NEXT WEEK. EXPECT MORE RAIN AND WINDY CONDITIONS.

.HYDROLOGY...FLOODING IS UNLIKELY OVER THE NEXT 7 DAYS.

.AVIATION...STRONG NORTHWEST FLOW ALOFT WILL WEAKEN TODAY WITH THE
FLOW ALOFT BECOMING WESTERLY TONIGHT. LIGHT GRADIENTS AT THE SURFACE
WITH WEAK HIGH PRESSURE OVER THE AREA WILL BECOME LIGHT EAST TO
SOUTHEAST TONIGHT AS THE HIGH SHIFTS EAST OF THE CASCADES.

SCATTERED SHOWERS CONTINUE TO FALL OVER THE SOUTHERN COASTAL WATERS
AND SOUTH OF A HOQUIAM TO OLYMPIA LINE. IN THE INTERIOR A VERY WEAK
CONVERGENCE ZONE CONTINUES FROM SOUTHEAST OF EVERETT TO AROUND
STAMPEDE PASS. THE SHOWERS AND CONVERGENCE ZONE SHOULD BE COMPLETELY
GONE BY ABOUT NOON LEAVING JUST SOME HIGH CLOUDS. HIGH CLOUDS WILL
INCREASE AND THICKEN TONIGHT WITH LIGHT PRECIPITATION DEVELOPING
LATE THIS EVENING ON THE COAST AND A FEW HOURS AFTER MIDNIGHT INLAND.

KSEA...JUST SCATTERED LOW CLOUDS THIS MORNING WITH SOME CIRRUS THIS
AFTERNOON AND THIS EVENING. A MID LEVEL DECK WILL DEVELOP AFTER
MIDNIGHT WITH LIGHT PRECIPITATION BEGINNING ABOUT 10Z. LIGHT EAST TO
NORTHEAST WINDS WILL DOMINATE THROUGH EARLY WEDNESDAY MORNING.
ALBRECHT

.MARINE...HIGH PRES OVER THE WATERS TODAY WILL SHIFT EAST OF THE
CASCADES TONIGHT.

A STRONG FRONTAL SYSTEM WILL MOVE THROUGH THE WATERS WEDNESDAY.
SOUTHEAST WINDS WILL INCREASE OVER THE COASTAL WATERS LATER TONIGHT
THEN SPREAD RAPIDLY INLAND WED MORNING. FULL GALES ARE LIKELY OVER
WATERS SUSCEPTIBLE TO STRONG SOUTHEAST WINDS STARTING WEDNESDAY
MORNING AND CONTINUING INTO THE AFTERNOON. THE FRONT IS EXPECTED TO
PASS THROUGH THE WATERS BY EARLY EVENING. STRONG POST FRONTAL
ONSHORE FLOW WILL FOLLOW THE FRONT AND WILL LIKELY RESULT IN GALES
OVER ALL OF THE WATERS.

A WEAK LOW WILL MOVE SOUTHEAST ACROSS THE WATERS FRIDAY. YET ANOTHER
LOW WILL PASS BY TO THE WEST OVER THE OFFSHORE WATERS ON SATURDAY.
