WWW.WEATHER.GOV/SEATTLE

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SEATTLE WA
315 AM PDT WED MAR 28 2012

.SYNOPSIS...SHOWERS WILL PERSIST TODAY BEHIND A FRONT THAT MOVED
ACROSS WESTERN WASHINGTON EARLY THIS MORNING. A STRONGER FRONTAL
SYSTEM WILL SWEEP ACROSS THE AREA LATE TONIGHT THROUGH THURSDAY
MORNING...LIKELY BRINGING HEAVY SNOW TO THE MOUNTAINS AND BRIEF HIGH
WIND TO THE COAST AND NORTHERN AREAS. THE ACTIVE PATTERN WILL
CONTINUE INTO NEXT WEEK.

&&

.SHORT TERM...A WEAKENING FRONT IS LIFTING NORTHEAST THROUGH WESTERN
WASHINGTON EARLY THIS MORNING AND SHOULD BE TO THE CANADIAN BORDER
BY AROUND 10Z. MESOSCALE MODELS INDICATE A DECREASE IN THE
PRECIPITATION FOR INTERIOR LOWLAND AREAS EAST OF THE OLYMPIC
PENINSULA LATER THIS MORNING INTO AFTERNOON...AND THE POPS WERE
ADJUSTED TO INDICATE THE SCATTERED NATURE OF THE SHOWERS. AN AREA
OF POST-FRONTAL INSTABILITY ASSOCIATED WITH COLDER AIR ALOFT
CONTINUES TO JUSTIFY THE MENTION OF ISOLATED THUNDERSTORMS OVER THE
COASTAL WATERS AND IMMEDIATE COASTAL AREAS LATER THIS MORNING.

THE STRONGER UPSTREAM FRONT MOVING INSIDE OF 150W AT 07Z SHOULD BE
APPROACHING OUR OUTER COASTAL WATERS BY 06Z THURSDAY OR SO. THE
NAM12 HAS SURFACE WINDS OF 40 KT ALONG THE COAST 06Z-09Z...WITH 60
TO 65 KT AT 925 MB...SOME OF WHICH COULD MIX DOWN TO THE SURFACE.
THE HIGH WIND WATCH FOR THE COAST AND NORTH INTERIOR LOOKS GOOD AND
WILL BE CONTINUED. WINDS FOR THE NORTH INTERIOR SHOULD PEAK 2 OR 3
HOURS LATER (09Z-12Z) AND MAY BE MARGINALLY WEAKER.

STRONG POST-FRONTAL SOUTHWEST FLOW EXPECTED LATE TONIGHT THROUGH
THURSDAY WILL PRODUCE SIGNIFICANT MOUNTAIN SNOWFALL ABOVE 3000 TO
3500 FEET. THE WRF-GFS 4KM GENERATES 12 HOUR SNOWFALL TOTALS ENDING
THURSDAY MID-MORNING OF 12 TO 18 INCHES IN THE CASCADES...EXCEPT
NEARLY 2 FEET FOR MOUNT BAKER AND MOUNT RAINIER. THE HIGHER
ELEVATIONS OF THE OLYMPICS COULD GET SEVERAL FEET OF SNOW ON
THURSDAY ALONE...IF THE MODEL OUTPUT IS CORRECT. THE WINTER STORM
WATCH FOR THE CASCADES/OLYMPICS LOOKS GOOD...AND IT SEEMS LIKELY
THAT THE DAY SHIFT WILL CONVERT IT TO A WARNING. LASTLY THERE SHOULD
BE HEAVY ENOUGH RAIN TO BRING THE SKOKOMISH RIVER TO OR ABOVE FLOOD
STAGE. THE FLOOD WATCH FOR MASON COUNTY HANDLES THIS.

THE 00Z MODEL RUNS CONTINUE TO EXHIBIT CONSIDERABLE DIFFERENCES WITH
ANOTHER SYSTEM EXPECTED ON FRIDAY. THE NAM/GFS BOTH HAVE A RATHER
UNIMPRESSIVE TROUGH MOVING ONSHORE ON FRIDAY...WHILE THE ECMWF HAS A
987 MB SURFACE LOW MOVING ONTO SOUTHERN VANCOUVER ISLAND IN THE
PREDAWN HOURS OF FRIDAY MORNING. THE CANADIAN IS SIMILAR TO THE
ECMWF...EXCEPT WITH A DEEPER LOW AND SLIGHTLY MORE NORTHERN TRACK.
CONFIDENCE IS LOW IN THE DETAILS FOR FRIDAY ASIDE FROM A WET
FORECAST.

.LONG TERM...THE MODEL DIFFERENCES CONTINUE INTO THE EXTENDED
FORECAST PERIOD...THOUGH WITH THE GENERAL IDEA OF ANOTHER SURFACE
LOW REACHING THE CENTRAL/SOUTHERN OREGON COAST ON SATURDAY...WITH
MORE PRECIPITATION SPREADING INTO OUR AREA AS THE SYSTEM LIFTS
NORTHEAST AND WEAKENS SOMEWHAT. THE GFS AND ECMWF DIFFER IN THE
DETAILS BUT BRING ANOTHER SYSTEM INLAND SUNDAY OR SUNDAY NIGHT. THE
ACTIVE PATTERN CONTINUES WELL INTO NEXT WEEK. NO CHANGES TO THE
EXTENDED FORECAST. 27

&&

.HYDROLOGY...NO CHANGES AT THIS TIME...THE WET SYSTEM TONIGHT AND
THURSDAY HAS A RELATIVELY LOW SNOW LEVEL...3000 FEET OR SO...SO
FLOODING IS UNLIKELY ON MOST AREA RIVERS. THE SKOKOMISH RIVER IN
MASON COUNTY IS PROBABLY THE ONLY RIVER THAN COULD FLOOD IN THIS
SCENARIO. IT COULD APPROACH FLOOD STAGE THURSDAY AND THE RIVER MODEL
HAS IT TOUCHING FLOOD STAGE. A FLOOD WATCH CONTINUES FOR THIS
THREAT.

MODELS DIVERGE CONSIDERABLY AFTER THAT WITH THE GFS SHOWING NO REAL
THREAT OF FLOODING BUT THE EURO SHOWING ANOTHER BATCH OF HEAVY
PRECIPITATION FRIDAY. THE EURO DOES SHOW MOST ENERGY HEADING INTO
OREGON...LIKE THE GFS...SO PERHAPS THERE IS NO THREAT OF FLOODING IN
THE EXTENDED PERIOD. BURKE/27

&&

.AVIATION...AN UPPER LEVEL AND SURFACE TROUGH WILL LIFT THROUGH WRN
WA EARLY THIS MORNING. MODERATE SLY FLOW ALOFT BECOMING SWLY THIS
AFTERNOON. THE AIR MASS WILL BE MOIST AND SLIGHTLY UNSTABLE WITH
RAIN AT TIMES. AN ISOLATED THUNDERSTORM IS STILL POSSIBLE NEAR THE
WA COAST THIS MORNING. CIGS TODAY WILL LIKELY REMAIN ABOVE 4K FT
EXCEPT LOCALLY DOWN TO 3K FT WITH HEAVIER RAIN BANDS.

ANOTHER MUCH STRONGER TROUGH AND SURFACE FRONT WILL AFFECT WRN WA
TONIGHT THROUGH EARLY THURSDAY MORNING. EXPECT STRONG SW FLOW ALOFT.
HEAVIER RAIN WILL BRING CIGS DOWN TO 2-3K FT.

KSEA...SE WINDS 5-10 KT BECOMING SLY BY 12Z. RAIN AT TIMES THROUGH
THURSDAY MORNING. CIGS GENERALLY ABOVE 4K FT...EXCEPT POSSIBLY
DROPPING TO 2-3K FT AT TIMES LATER TONIGHT.

&&

.MARINE...A FRONTAL SYSTEM LIFTING MAINLY N THROUGH THE COASTAL
WATERS EARLY THIS MORNING IS PRODUCING STRONG SE GRADIENTS ACROSS
THE INLAND WATERS. SMALL CRAFT WINDS WILL CONTINUE TODAY ACROSS THE
INLAND WATERS EXCEPT PUGET SOUND WHERE WINDS SHOULD PEAK NEAR 20 KT
THIS MORNING. LOW END GALES DEVELOPED AT DESTRUCTION THE PAST COUPLE
HOURS. WINDS OVER THE COASTAL WATERS WILL EASE A BIT LATER THIS
MORNING UNTIL THE NEXT STRONGER FRONT ARRIVES THIS EVENING.

THE NEXT FRONT WILL BRING GALES TO THE COASTAL WATERS...ENTRANCES TO
THE STRAIT...AND N INLAND WATERS. THE PUGET SOUND WILL PROBABLY JUST
SEE SMALL CRAFT CONDITIONS. STRONGEST WINDS WILL OCCUR FROM LATE
WEDNESDAY EVENING THROUGH EARLY THURSDAY MORNING. IT IS POSSIBLE THE
WINDS OVER THE COASTAL WATERS COULD APPROACH STORM FORCE FROM A
WHILE.

A RELATIVE LULL IN THE WINDS BETWEEN WEATHER SYSTEM LATE
THURSDAY/FRIDAY. ANOTHER LOW WILL AFFECT THE WATERS BY LATE FRIDAY
AND SATURDAY.

&&

.SEW WATCHES/WARNINGS/ADVISORIES...
WA...WINTER STORM WATCH CASCADES AND OLYMPICS FROM THIS EVENING
     THROUGH THURSDAY EVENING.
     HIGH WIND WATCH COAST AND NORTHWEST INTERIOR FROM THIS EVENING
     THROUGH THURSDAY MORNING.
