WWW.WEATHER.GOV/SEATTLE

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SEATTLE WA
900 PM PST THU NOV 29 2012

.SYNOPSIS...UNSETTLED CONDITIONS WILL CONTINUE THROUGH THIS WEEKEND
DUE TO A SERIES OF PACIFIC STORMS IMPACTING THE REGION.

&&

.SHORT TERM...A LARGE DEEP UPPER TROUGH REMAINS CENTERED OFFSHORE
ALONG 140W...WITH A 130 KT SOUTHWESTERLY JET EXTENDING FROM THE BASE
OF THE TROUGH INTO NORTHERN CALIFORNIA. THIS EVENING WESTERN
WASHINGTON IS BETWEEN FRONTS THAT ARE ROTATING AROUND THE TROUGH.
THE FRONT THAT MOVED THROUGH THE FORECAST AREA THIS MORNING IS NOW
WELL NORTH AND EAST...WHILE A LARGE AREA OF CONVECTIVE PRECIPITATION
IS OFFSHORE. SHOWERS CONTINUE OVER WESTERN WASHINGTON IN THE MOIST
WEAKLY UNSTABLE SOUTHWEST FLOW ALOFT. WE STILL HAVE MODERATELY
STRONG SOUTHEAST PRESSURE GRADIENTS AT THE SURFACE...WITH LOCALLY
WINDY CONDITIONS MAINLY IN THE NORTH INTERIOR.

A VORTICITY LOBE ROTATING THROUGH THE SOUTHEAST QUADRANT OF THE
UPPER LOW WILL APPROACH THE PACIFIC NORTHWEST COAST LATE TONIGHT AND
MOVE NORTHEAST THROUGH THE FORECAST AREA FRIDAY. THIS FEATURE WILL
LIKELY ENHANCE THE CONVECTIVE REGION CURRENTLY OVER THE OFFSHORE
WATERS. ANOTHER FRONTAL SYSTEM WILL DEVELOP ALONG THE SOUTHWEST SIDE
OF THE UPPER LOW TONIGHT...THEN SWING THROUGH THE BASE OF THE TROUGH
FRIDAY AND ACROSS WESTERN WASHINGTON FRIDAY NIGHT. THIS WILL MEAN
MORE WET WEATHER AND LOCALLY WINDY CONDITIONS. THE SNOW LEVEL WILL
REMAIN NEAR 5000 FT...BUT SPOTTY FREEZING RAIN IS POSSIBLE IN THE
PASSES.

SHOWERY WEATHER WILL CONTINUE SATURDAY...WITH THE SNOW LEVEL FALLING
TO AROUND 3500 FT. ANOTHER ORGANIZED FRONTAL SYSTEM WILL MOVE
THROUGH THE REGION SATURDAY NIGHT AND SUNDAY...AS THE UPPER TROUGH
LIFTS NORTHEAST ACROSS BRITISH COLUMBIA AND A STRONG JET STREAK
MOVES INLAND TO THE SOUTH AND THEN EAST OF WESTERN WASHINGTON.
MCDONNAL

.LONG TERM...HERE IS THE LONG TERM SECTION FROM THE AFTERNOON
ISSUANCE OF THE FORECAST DISCUSSION -- NOT TOO MUCH CHANGE IN WHAT
WE HAVE BEEN SEEING THE PAST FEW DAYS. THE MEDIUM RANGE SOLUTIONS
STILL WERE INCONSISTENT WITH THE POSSIBILITY OF AN ATMOSPHERIC RIVER
OF MOISTURE IMPACTING THE REGION ABOUT THE MIDDLE OF NEXT WEEK. THE
MODELS INDICATED A DISORGANIZED / IN PIECES/ PLUME OF SUBTROPICAL
MOISTURE IMPACTING THE CWA AS WELL AS INDICATED LOWER SNOW
LEVELS...WHICH WOULD MEAN MORE OF A HEAVY SNOW EVENT FOR THE
MOUNTAINS THAN A HEAVY RAIN EVENT.

ESSENTIALLY...DURING THIS PERIOD...THE UPPER JET WILL LIFT BACK
NORTH ACROSS OUR AREA...RESULTING IN CONTINUED UNSETTLED CONDITIONS.

&&

.HYDROLOGY...THE WET WEATHER THAT WILL CONTINUE THROUGH SUNDAY --
WHILE NOT VERY SIMILAR TO THE CLASSIC FLOOD-PRODUCING WEATHER
PATTERN FOR WESTERN WASHINGTON -- COULD EVENTUALLY DRIVE THE
EXCEPTIONALLY FLOOD-PRONE SKOKOMISH RIVER ABOVE FLOOD STAGE.

THE SKOKOMISH RIVER NEAR POTLATCH WAS AT A STAGE OF 15.0 FT AT 845
PM AND RISING SLOWLY. FLOOD STAGE IS 16.5 FT. IT WILL CREST BELOW
FLOOD STAGE IN THE NEXT FEW HOURS. HOWEVER ANOTHER 3 TO 4 INCHES OF
RAIN WILL FALL OVER THE BASIN FRIDAY THROUGH SATURDAY NIGHT...AND
THE CUMULATIVE EFFECT OF THESE SUCCESSIVE STORMS COULD EVENTUALLY
PUSH IT ABOVE FLOOD STAGE. IF IT DOES FLOOD IT WOULD MOST LIKELY
OCCUR SATURDAY OR SATURDAY NIGHT.

AS EARLIER DISCUSSIONS MENTIONED...PREVIOUS RUNS OF ESPECIALLY THE
EUROPEAN MODEL SHOWED A MORE CLASSICALLY FLOOD THREATENING PATTERN
DEVELOPING AROUND TUESDAY OF NEXT WEEK. MORE RECENT RUNS LOOK LESS
THREATENING BUT WE STILL NEED TO REMAIN IN A MODE OF WATCHFUL
WAITING.   MCDONNAL

&&

.AVIATION...A DEEP LOW PRESSURE CENTER OFFSHORE WILL SHIFT TO NEAR
HAIDA GWAII THROUGH SATURDAY NIGHT. SEVERAL DISTURBANCES ASSOCIATED
WITH THE LOW WILL MOVE THROUGH THE AREA TONIGHT THROUGH SATURDAY
NIGHT FOR SHOWERS OR RAIN AT TIMES. THE WIND ALOFT WILL REMAIN
FAIRLY STRONG...RISING TO AROUND 40KT AT TIMES ABOVE ABOUT 3000FT.
THE MOUNTAINS WILL REMAIN OBSCURED. 19

KSEA...SHOWERS OR RAIN AT TIMES...CONDITIONS WILL AVERAGE ABOUT
OVC040 WITH A SELY BREEZE TONIGHT THROUGH FRIDAY. THE TIME HEIGHT
CROSS SECTION FOR SEATTLE SHOWS VERY LITTLE CHANGE THROUGH FRIDAY
NIGHT. 19

&&

.MARINE...A DEEP LOW PRESSURE CENTER OFFSHORE WILL SHIFT TO NEAR
HAIDA GWAII THROUGH SATURDAY NIGHT. SEVERAL DISTURBANCES ASSOCIATED
WITH THE LOW WILL MOVE THROUGH THE AREA TONIGHT THROUGH SATURDAY
NIGHT. AS EACH DISTURBANCE ROTATES THROUGH THE AREA THE PRESSURE
GRADIENTS OUGHT TO TIGHTEN UP ENOUGH TO OCCASIONALLY HIT 35KT GALES
OVER THE COASTAL WATERS...THE FORECAST WILL SAY 25-35. FOR THE EAST
ENTRANCE TO THE STRAIT AND NORTHERN WATERS WILL FORECAST 20-30KT
WITH SMALL CRAFT ADVISORY MOST INLAND WATERS. 19

COASTAL FLOOD ADVISORIES REMAIN IN EFFECT FROM PUGET SOUND NORTH TO
THE CANADIAN BORDER AND A COASTAL FLOOD WATCH FOR LA PUSH AND THE
QUILEUTE TRIBE LOWER VILLAGE...AS THE RISK FOR MINOR TIDAL OVERFLOW
WILL STILL BE PRESENT TOMORROW AND SATURDAY.

SMR

&&

.SEW WATCHES/WARNINGS/ADVISORIES...
WA...COASTAL FLOOD ADVISORY FOR MINOR TIDAL OVERFLOW AT HIGH TIDE
     FROM PUGET SOUND NORTH TO THE CANADIAN BORDER.
     COASTAL FLOOD WATCH FOR MINOR TIDAL OVERFLOW AT HIGH TIDE FOR
