AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SEATTLE WA
1100 AM PST MON NOV 22 2010
.SYNOPSIS...A COLD UPPER LEVEL LOW WILL MOVE SOUTH OVER WESTERN
WASHINGTON BY THIS EVENING...THEN MOVE EAST OVER EASTERN WASHINGTON
TONIGHT. THIS LOW WILL BRING PERIODS OF SNOW TO MUCH OF THE AREA
THROUGH TONIGHT. COLD DRY NORTH FLOW ALOFT WILL DEVELOP OVER THE
AREA TUESDAY AND WEDNESDAY...BRINGING MOSTLY CLEAR SKIES BUT KEEPING
TEMPERATURES BELOW FREEZING IN MOST AREAS. THE WEATHER IS EXPECTED
TO RETURN TO SEASONABLE TEMPERATURES WITH RAIN AFTER THE MIDDLE OF
THE WEEK.
&&
.SHORT TERM...THE AFD WAS DELAYED THIS MORNING DUE TO HIGHER
PRIORITY WARNINGS AND ADVISORIES. A BIT MORE DEVELOPMENT THAN
PREVIOUSLY EXPECTED THIS MORNING AS THE UPPER LEVEL LOW APPROACHES
THE AREA FROM B.C. FORECASTS WERE IN FAIRLY GOOD SHAPE EXCEPT FOR
THE STRONGER DEVELOPMENT. HAVE UPGRADED TO A WINTER STORM WARNING
FOR THE STRAIT...PUGET SOUND REGION AND THE SW INTERIOR. EXPECT
SNOW ACCUMULATIONS TO BE HIGHLY VARIABLE...BASED ON TERRAIN EFFECTS
AND THE BANDED NATURE OF THE SNOW AS THE LOW MOVES OVER THE REGION.
AT LEAST THE AIR MASS IS COLD ENOUGH TO CONFIDENTLY SAY RAIN WILL
NOT BE A CONSIDERATION. FORECASTS ARE TILTED QUITE A BIT TOWARD THE
NAM12...ESPECIALLY WITH REGARD TO SNOW ACCUMULATIONS. BASED ON THE
MOVEMENT OF THE MAIN LOW THE SNOW WILL START TAPERING OFF THROUGH
THE EVENING...BUT HAVE EXTENDED THE WARNINGS/ADVISORIES UNTIL 06Z TO
PLAY IT SAFE.
GFS SHOWS REALLY STRONG PRESSURE GRADIENTS DEVELOPING ACROSS W WA
STARTING LATE THIS AFTERNOON AND EXTENDING THROUGH TONIGHT. HAVE
UPGRADED TO A HIGH WIND WARNING FOR WESTERN WHATCOM COUNTY AND THE
SAN JUAN ISLANDS. WILL CONTINUE WITH A WIND ADVISORY FOR THE
REMAINDER OF THE NW INTERIOR. SHOULD BE WINDY ALONG THE STRAIT AND
OVER PUGET SOUND BUT EXPECT WINDS TO BE BELOW ADVISORY
CRITERIA...BUT IT COULD BE CLOSE.
AFTER THE UPPER LEVEL LOW MOVES EAST TONIGHT...COLD DRY N FLOW ALOFT
DEVELOPS OVER W WA...BRINGING A COLD AIR MASS OVER THE AREA. THIS
WILL KEEP TEMPERATURES MOSTLY BELOW FREEZING TUESDAY AND WEDNESDAY.
COULD SEE SOME NEAR RECORD LOWS IN SOME AREAS WEDNESDAY MORNING
BASED ON THE LATEST MAV/MET GUIDANCE. KAM
.LONG TERM...PREVIOUS DISCUSSION FROM THE 4 AM AFD...UPPER LEVEL
RIDGE WEAKENING AND MOVING OVER WESTERN WASHINGTON ON THURSDAY.
MODELS IN FAIRLY GOOD AGREEMENT IN BRINGING A WARM FRONT CLOSE
ENOUGH TO THE AREA TO HAVE A CHANCE OF RAIN IN THE FORECAST FOR
THANKSGIVING. TRAILING COLD FRONT MOVING INTO WESTERN WASHINGTON ON
FRIDAY WITH THE PRECIPITATION OUT AHEAD OF THE FRONT SPREADING INTO
THE AREA THURSDAY NIGHT. A COOL UPPER LEVEL TROUGH SETS UP OFF THE
COAST FRIDAY NIGHT AND SATURDAY WITH A LESS ORGANIZED SYSTEM MOVING
INTO THE AREA ON SATURDAY. MODEL SOLUTIONS DISAGREE ON THE TIMING OF
THIS FEATURE WITH THE GFS A LITTLE SLOWER WHILE THE ECMWF BRING THE
SYSTEM THROUGH FAST ENOUGH TO SHOW SOME IMPROVEMENT IN THE WEATHER
FOR SUNDAY. NOT ENOUGH CONFIDENCE IN EITHER SOLUTION TO CHANGE THE
FORECAST AND WILL STAY WITH THE LIKELY POPS THROUGH THE WEEKEND.

998 MB SURFACE LOW OFF THE WA COAST TRACKS SE ACROSS SRN WA
TODAY...THEN DROPS S OF THE AREA OVERNIGHT. STRONG NLY LOW LEVEL
FLOW WILL DEVELOP ACROSS WRN WA TODAY THROUGH TONIGHT. THE FLOW
ALOFT WILL BE SWLY...SWITCHING NLY LATER TODAY AND TONIGHT. MOIST
AND UNSTABLE CONDITIONS.
UPDATE TO SNOW FOR TODAY AND TONIGHT...IT NOW APPEARS EVERYTHING IS

AND TONIGHT. LIGHT SLY WIND 4-8 KT...WILL SWITCH THIS
AFTERNOON...TIMING IS DIFFICULT. BEST GUESS IS A SWITCH TO N WIND
15-25 KT WITH GUSTS 35 KT AROUND 22Z. THIS WILL CAUSE BLOWING AND
DRIFTING SNOW. WIND WILL EASE OUT OF THE N AFTER 09Z TONIGHT.
&&
.MARINE...STRONG NLY GRADIENTS TODAY WILL RESULT IN WIDESPREAD GALES
FOR MOST WATERS. THE N INLAND WATERS COULD PUSH STORM
