ADDITION TO THE LOWLAND SNOW THIS WILL BE A HEAVY SNOW PRODUCER FOR
THE MOUNTAINS WITH ANOTHER 1 TO 2 FEET OF NEW SNOW ON WEDNESDAY
ADDING ON TO THE 1 OR 2 FEET OF NEW SNOW FROM YESTERDAY AND TODAY.
HAVE GONE AHEAD AND UPGRADED THE WINTER STORM WATCH TO A WARNING FOR
MOST OF WESTERN WASHINGTON LATE TONIGHT THROUGH WEDNESDAY EVENING.

THE QUESTION NOW BECOMES WHEN DOES THE WARM AIR ARRIVE TO CHANGE THE
PRECIPITATION TYPE OVER TO RAIN FROM SNOW. ALL OF THE COMPUTER
MODELS AGREE THAT THE PARENT LOW ASSOCIATED WITH THE WARM FRONT WILL
MOVE INLAND SOUTH OF SEATTLE. THIS KEEPS AT LEAST THE NORTHERN
PORTION OF THE CWA IN THE COLDER AIR MASS. WHILE IT LOOKS LIKE THE
SNOW RATES WILL TAPER OFF SIGNIFICANTLY WEDNESDAY NIGHT THE
TRANSITION FROM SNOW TO RAIN HAS NOW BEEN PUSHED BACK INTO THURSDAY
FOR EVERYONE BUT THE SOUTHWEST INTERIOR AND THE CENTRAL COAST. ONCE
AGAIN THE NORTHWEST INTERIOR WILL BE THE LAST TO TRANSITION TO THE
WARMER AIR MASS AND WITH THE LACK OF ONSHORE SURFACE GRADIENTS THE
COLD AIR COULD HANG IN THERE UNTIL FRIDAY.

.LONG TERM...MODEL CONSISTENCY BREAKS DOWN IN THE EXTENDED PERIOD
BUT THE GENERAL IDEA OF A CHANGE BACK TO A WARMER AND WETTER PATTERN
IS STILL INTACT. THE ECMWF IS STILL INDICATING WINDY CONDITIONS ON
SATURDAY BUT THE SURFACE LOW IS 10 MB WEAKER VERSUS LAST NIGHTS RUN.
FOR NOW BROAD BRUSH FORECAST WILL BE MAINTAINED. FELTON

&&

.HYDROLOGY...NO WIDESPREAD RIVER FLOODING IS EXPECTED IN THE NEXT
SEVEN DAYS. SMALLER AND MORE FLOOD PRONE RIVERS MAY SEE SOME
FLOODING AFTER THURSDAY. THE TRANSITION OF PRECIPITATION TYPE FROM
SNOW TO RAIN COULD RESULT IN URBAN AND SMALL STREAM FLOODING
THURSDAY INTO FRIDAY BUT WITH A SLOWER WARM UP PREDICTED THE CHANCES
OF THIS SCENARIO OCCURRING ARE REDUCED. FELTON

&&

.AVIATION...WESTERLY FLOW ALOFT WILL CONTINUE THROUGH TONIGHT...AS
AN UPPER TROUGH MOVES INTO THE AREA FROM THE NORTHWEST AND A
DEVELOPING FRONTAL SYSTEM APPROACHES FROM THE SOUTHWEST. A WEAK
SURFACE LOW WILL REMAIN JUST OFF VANCOUVER ISLAND NEAR PACHENA POINT
THROUGH THIS EVENING WITH A WEAK TROUGH EXTENDING ACROSS WESTERN
WASHINGTON. THE AIR MASS WILL REMAIN MOIST.

SCATTERED SHOWERS -- MOSTLY FALLING AS SNOW -- CONTINUED ACROSS
WESTERN WASHINGTON OVERNIGHT. IFR CONDITIONS WITH CEILINGS IN THE
300-700 FT RANGE WERE FAIRLY COMMON AT 3 AM...WITH LOCAL MVFR
CONDITIONS. IN ADDITIONS SNOW SHOWERS WERE LOCALLY REDUCING
VISIBILITY TO 2-4SM. THESE CONDITIONS WILL CONTINUE...GENERALLY
SPEAKING...THROUGH THIS MORNING. A RELATIVE BREAK IN THE SNOW
SHOWERS WITH MINOR IMPROVEMENT IN CEILINGS IS LIKELY THIS AFTERNOON.
A SIGNIFICANT SNOWFALL EVENT IS EXPECTED LATE TONIGHT THROUGH
WEDNESDAY.

KSEA...SOUTH WIND 8 TO 14 KT AND GUSTING 24 KT...PROBABLY SHIFTING
TO NORTHERLY LATE THIS AFTERNOON OR EVENING. OCCASIONAL SNOW SHOWERS
WILL CONTINUE THIS MORNING...LIKELY FOLLOWED BY A RELATIVE BREAK IN
PRECIPITATION THIS AFTERNOON AND EVENING. ADDITIONAL ACCUMULATION
DURING THE NEXT 24 HOURS SHOULD BE AROUND 1 INCH...AND MOST OF THAT
WILL FALL THIS MORNING. THE TEMPERATURE WILL CHANGE LITTLE...
POSSIBLY DIPPING TO 32 DEGREES EARLY THIS MORNING AND THEN PEAKING
AROUND 35 THIS AFTERNOON. THEN IT WILL FALL TO FREEZING THIS EVENING
AND REMAIN AT OR JUST BELOW FREEZING THROUGH WEDNESDAY NIGHT. A MUCH
MORE SIGNIFICANT SNOWFALL EVENT IS EXPECTED LATE TONIGHT...BEGINNING
AROUND 4 AM...AND CONTINUING THROUGH WEDNESDAY WITH ACCUMULATIONS
AROUND 8 INCHES LIKELY.   MCDONNAL

&&

.MARINE...A 1011 MB SURFACE LOW WILL REMAIN JUST OFF VANCOUVER
ISLAND NEAR PACHENA POINT TODAY...WITH HIGH PRESSURE OVER BRITISH
COLUMBIA AND NORTHERN CALIFORNIA. SMALL CRAFT ADVISORY WESTERLIES
WILL CONTINUE THIS MORNING IN THE CENTRAL STRAIT OF JUAN DE FUCA
WITH SMALL CRAFT ADVISORY SOUTHERLIES IN THE PUGET SOUND REGION.

A VIGOROUS DEVELOPING FRONTAL SYSTEM WILL MOVE INTO THE REGION FROM
THE WEST TONIGHT AND WEDNESDAY...WHILE THE SURFACE HIGH REMAINS OVER
BRITISH COLUMBIA. THIS WILL PRODUCE STRONG NORTHEAST PRESSURE
GRADIENTS ACROSS THE REGION...WITH GALE FORCE WINDS EXPECTED OVER
THE COASTAL WATERS...WEST ENTRANCE STRAIT OF JUAN DE FUCA...CENTRAL
STRAIT...AND NORTHERN INLAND WATERS. THE GALE WATCH THAT WAS POSTED
MONDAY EVENING IS BEING UPGRADED TO A GALE WARNING. SMALL CRAFT
ADVISORY WINDS ARE LIKELY OVER THE EAST ENTRANCE STRAIT...ADMIRALTY
INLET...AND PUGET SOUND AND HOOD CANAL.

ANOTHER WEAKER SURFACE LOW WILL MOVE INTO THE COASTAL WATERS...MOST
LIKELY THE OREGON COASTAL WATERS...ON THURSDAY. THEN ANOTHER FAIRLY
VIGOROUS FRONTAL SYSTEM WILL MOVE THROUGH THE AREA FRIDAY THROUGH
SATURDAY.   MCDONNAL

&&

.AVALANCHE...SNOWFALL AND WINDS INCREASING ACROSS THE NW MOUNTAINS
EARLY THIS MORNING WITH LOTS MORE TO COME DURING NEXT 36-48
HOURS...ALONG WITH STRENGTHENING WINDS AND OVERALL VERY SLOW WARMING
TREND. COMBINED WITH HARD CRUSTS AND POOR BOND TO SOME VERY LOW
DENSITY SNOW THAT FELL LAST WEEKEND INTO EARLY MONDAY...THIS SHOULD
PRODUCE AN INCREASINGLY SENSITIVE AND UNSTABLE SNOWPACK THROUGHOUT
THE REGION TUESDAY AND WEDNESDAY. AVALANCHE WARNINGS ALREADY IN
EFFECT FOR DEVELOPING HIGH DANGER...AND WITH WARMING AND ADDITIONAL
HEAVY TO VERY HEAVY SNOW...SOME QUITE DENSE...AVALANCHE ACTIVITY
SHOULD BECOME LARGE AND FREQUENT...PROBABLY LEADING TO EXTREME
DANGER ON WEDNESDAY. DUE TO VERY DANGEROUS CONDITIONS GETTING
WORSE...BACK COUNTRY TRAVEL NOT RECOMMENDED TUESDAY AND IT SHOULD BE
AVOIDED WEDNESDAY. SEE NWAC.US FOR MORE INFO. MOORE
