AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE SEATTLE WA
930 AM PST SUN DEC 25 2011

.SYNOPSIS...A COLD FRONT MOVING ONSHORE THIS MORNING WILL BRING RAIN
TO THE AREA AND BREEZY CONDITIONS MAINLY TO THE COAST AND NORTH
INTERIOR.  SHOWERS WILL TAPER OFF THIS EVENING AS A WEAK RIDGE OF
HIGH PRES BUILDS INTO THE AREA. ANOTHER FRONT WILL APPROACH THE AREA
MONDAY AND MOVE INLAND MONDAY EVENING. THIS PATTERN WILL CONTINUE
FOR THE UPCOMING WEEK AS STRONG ZONAL FLOW SETS UP OVER THE NORTH
PACIFIC... ALLOWING A SERIES OF PACIFIC FRONTAL SYSTEMS TO MOVE
THROUGH THE AREA.

&&

.SHORT TERM...UPDATED THE MARINE SECTION BELOW. SATELLITE AND RADAR
IMAGERY SHOWS INCOMING FRONT MOVING INTO THE COASTAL WATERS THIS
MORNING. ONSET OF RAIN AT 16Z FOR THE COAST A BIT LATER THAN
ANTICIPATED...MORNING MODEL RUNS PICKING UP ON THIS WITH
PRECIPITATION SPREADING INLAND BY MIDDAY AND INTO THE CASCADES IN
THE EARLY AFTERNOON HOURS. KLGX AND S-BAND PROFILER AT WESTPORT
SHOWING SNOW LEVELS AROUND 4000 FEET AS OF 17Z ALONG THE
COAST...EXPECT SNOW LEVELS IN THE MOUNTAINS TO DROP TO AROUND 3500
FEET WITH THE FRONT AND 2500 FEET THIS EVENING. ANTICIPATE 4 TO 8
INCHES OF SNOW ABOVE ABOUT 3500 FEET THROUGH TONIGHT FOR THE
CASCADES AND MARGINAL WINTER WEATHER ADVISORY AMOUNTS AT MT
BAKER...STEVENS PASS...AND PARADISE. WILL UPDATE THE ADVISORY FOR
ABOVE 3500 FEET LATER THIS MORNING.

SHOWERS TAPER OFF TONIGHT BEHIND THE FRONT AS WEAK HIGH PRESSURE
BUILDS INTO THE AREA FROM THE WEST THEN SHIFTS EAST OF THE CASCADES
MON MORNING AHEAD OF THE NEXT SYSTEM.

THE NEXT FRONT AT THE LEADING EDGE OF A STRENGTHENING PACIFIC JET
STREAM WILL MOVE ACROSS THE AREA MONDAY EVENING BRINGING A
PERIOD OF MODERATE TO LOCALLY HEAVY RAIN TO THE COAST AND BREEZY TO
LOCALLY WINDY CONDITIONS. WITH THE LOWER SNOW LEVELS AT THE ONSET OF
THIS SYSTEM...MORE WIDESPREAD ADVISORY SNOWFALL AMOUNTS ARE EXPECTED
FOR THE MOUNTAINS WITH THIS FRONT.

SNOW LEVELS WILL BEGIN TO RISE TUESDAY MORNING AHEAD OF THE NEXT
SYSTEM...RAINFALL WILL PICK UP AGAIN LATER TUESDAY AS THIS WAVE IN
THE SERIES MOVES INTO THE AREA. IN ADDITION TO A RENEWED SHOT OF
RAIN FOR THE LOWER ELEVATIONS...THIS SYSTEM WILL BRING ANOTHER ROUND
OF MOUNTAIN SNOW ABOVE 4000 FEET. TEMPERATURES WILL RANGE FROM THE
MID 30S TO LOWER 40S AT NIGHT AND REMAIN IN THE LOWER TO MID 40S
DURING THE DAY THROUGH TUESDAY.

.LONG TERM...FROM PREVIOUS DISCUSSION...MODELS CONTINUE TO ADVERTISE
A WET AND ACTIVE PERIOD THROUGH THE WEEK AND POSSIBLY INTO NEW YEARS
DAY. LOCALLY HEAVY RAINFALL IS POSSIBLE TUESDAY NIGHT INTO EARLY
WEDNESDAY AND AGAIN WEDNESDAY NIGHT...FRIDAY...AND NEXT SATURDAY AS
MOISTURE GETS TRANSPORTED EASTWARD FROM THE SUBTROPICAL WESTERN
PACIFIC. A 140-160 KNOT 300 MB JET MAY ENERGIZE INDIVIDUAL FRONTAL
WAVES RESULTING IN WINDY CONDITIONS AT TIMES. THE ECMWF IS GENERALLY
ABOUT 20 KT STRONGER WITH THE JET THAN THE GFS. SNOW LEVELS WILL
RISE TO ABOUT 5000 FEET MIDWEEK THEN FALL BACK TO ABOUT 3000 FEET BY
NEXT FRIDAY. ALBRECHT

&&

.HYDROLOGY...A SERIES OF WET WEATHER SYSTEMS WILL ARRIVE OVER THE
NEXT WEEK OR SO. ALTHOUGH NO PARTICULAR SYSTEM LOOKS LIKE IT WILL
CAUSE WIDESPREAD FLOODING...RIVERS WILL CERTAINLY RISE. THE
SKOKOMISH RIVER IS LIKELY TO REACH ADVISORY STAGE AT TIMES AND COULD
GO ABOVE FLOOD STAGE AS WELL. BURKE

&&

.AVIATION...THE COLD FRONT NEAR THE COAST AT 8AM WILL MOVE THROUGH
WESTERN WA BY MIDDAY. IT IS WEAKER AND NOT AS WET AS EXPECTED...BUT
THERE WILL STILL BE SEVERAL HOURS OF CIGS AND PERHAPS VSBY DROPPING
TO MVFR AND I WILL TUNE THE TAFS A BIT BUT STILL KEEP SOME RAINY
BLUSTERY WEATHER IN THERE WITH THE FRONT ITSELF. ONSHORE FLOW AND
SCATTERED SHOWERS WILL BE THE RULE BEHIND THE FRONT WITH PARTIAL
CLEARING PERIODS AFTER THE FROPA. THE MOUNTAINS WILL CATCH THE WORST
OF IT AND THE MOUNTAINS THAT ARE NOT YET OBSCURED WILL BE LATER THIS
MORNING...AND WILL REMAIN MOSTLY OBSCURED BEHIND THE FRONT THIS
AFTERNOON AND EVENING. 19

KSEA...WILL HANG ON TO SOME OF THE BREEZY WET WEATHER IN THE CURRENT
TAF WITH THE FRONT STILL TO COME THROUGH LATER THIS MORNING. THE
SYSTEM LOOKS WEAK ON SATELLITE IMAGERY BUT PRETTY VIGOROUS ON THE
COASTAL RADAR...SO CIGS AROUND 020 ARE A STILL A GOOD BET AS THE
FRONT MOVES OVER THE SEATTLE AREA LATE THIS MORNING WITH A MIDDAY
FROPA. 19

&&

.MARINE...UPDATED...AT 9AM GRADIENTS SPIKED NICELY AND AST-UIL ROSE
TO +6MB AND OLM-BLI ROSE TO 5MB...SO THAT WILL HELP VERIFY THE GALE
WARNINGS AS THE FRONT SEEMS TO HAVE A LITTLE MORE PUNCH NOW THIS
MORNING. I MADE NO BIG CHANGES TO THE MORNING FCSTS AND GRIDS WHICH
ARE STILL A GOOD MATCH TO THE LATEST 12Z RUN OF THE UW 4KM MESOSCALE
SOLUTION. THE FRONT WILL BE THROUGH THE COASTAL WATERS BY 11AM SO I
HAVE ENDED THE GALE AT THAT TIME AND STARTED A SMALL CRAFT ADVISORY.
19

WA...NONE.
PZ...GALE WARNING FOR THE COASTAL WATERS TIL 11AM.
GALE WARNING FOR THE EAST ENTRANCE TO THE STRAIT...ADMIRALTY
