AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SEATTLE WA
143 AM PST FRI MAR 2 2012

.SYNOPSIS...A WARM FRONT BRUSHING PAST THE AREA TO THE WEST WILL
BRING SOME LIGHT PRECIPITATION TO THE AREA TODAY AND TONIGHT.
EXPECT A CONTINUED CHANCE OF RAIN ON SATURDAY. HIGH PRESSURE ALOFT
ON SUNDAY WILL PROVIDE THE REGION WITH DRY AND MILD WEATHER.
ALAS...ANOTHER COLD LOW PRESSURE SYSTEM WILL BRING MORE RAIN AND
MOUNTAIN SNOW TO THE AREA ON MONDAY.

&&

.SHORT TERM...
AN UPPER RIDGE CENTERED OFFSHORE WILL MAINTAIN A NW FLOW ALOFT OVER
THE REGION THROUGH TONIGHT. A WMFNT OFFSHORE WILL BRUSH THE COASTAL
WATERS LATER TODAY. THE CWA WILL BE UNDER A WAA PATTERN THROUGH
TONIGHT...THUS LOOK FOR RAIN TO DEVELOP OVER THE AREA DURING THE DAY
TODAY. HAVE BUMPED UP POPS SINCE CONFIDENCE WAS HIGH THAT MOST
PLACES WILL RECEIVE MEASURABLE PRECIP.

THE FLOW WILL BECOME WLY ON SATURDAY AS THE RIDGE AXIS SHIFTS
INLAND...WITH WLY FLOW PERSISTING ON SUNDAY. THIS WILL SERVE TO
SHUNT THE BAROCLINIC ZONE NWD AND DECREASE THE PRECIP THREAT AS TIME
WEARS ON. SUNDAY WILL ESSENTIALLY BE A DRY DAY FOR THE CWA. THE AIR
MASS WILL ALSO BE RATHER MILD ON SUNDAY...THUS ANTICIPATE TEMPS AT
MANY LOWLAND LOCALES TO CLIMB INTO THE LOW TO MID 50S...WHICH IS
NEAR NORMAL FOR THIS TIME OF THE YEAR.

THE NEXT LOW PRES SYSTEM...EMANATING OUT OF THE GULF OF AK...WILL
BEGIN IMPACTING THE REGION SUNDAY NIGHT FOR AN INCREASING THREAT OF
PRECIP. THE MODELS WERE FASTER IN BRINGING THE PRECIP BACK INTO THE
AREA...THUS HAVE FOLLOWED SUIT. IF THE ECMWF IS CORRECT...THE DRY
FORECAST FOR DAYTIME SUNDAY MIGHT BE IN JEOPARDY.

.LONG TERM...
EXPECT A VIGOROUS CDFNT TO SWEEP ACROSS THE CWA ON MON AND USHER IN
A COLDER AIR MASS. THERE WILL PROBABLY BE A BRIEF PERIOD OF LOCALLY
HEAVY PRECIP WITH AND AHEAD OF THIS FRONT. THE COLD UPPER TROF IS
EXPECTED TO MOVE OVER THE PAC NW MON NIGHT AND THEN INTO THE GREAT
BASIN ON TUE. THE ECMWF BROUGHT ANOTHER SYSTEM ACROSS THE AREA FROM
THE NW ON WED WHEREAS THE GFS HAD AN UPPER RIDGE OVER THE REGION.
BOTH MODELS WERE DRY FOR THU. CONFIDENCE IN THE FORECAST BEYOND TUE
WAS NOT VERY HIGH.

&&

.HYDROLOGY...
FLOODING OF AREA RIVERS IS NOT EXPECTED FOR THE NEXT 7 DAYS.

&&

.AVIATION...A WARM FRONT WILL MOVE THROUGH THE AREA TODAY...LIFTING
NORTH OF THE REGION TONIGHT WITH NORTHWEST FLOW ALOFT. AT THE
SURFACE...SOUTHERLY GRADIENTS WILL BECOME SOUTHWESTERLY TONIGHT
BEHIND THE WARM FRONT. AIR MASS MOIST AND STABLE.

RAIN AND LOWER CLOUDS WILL DEVELOP TODAY AS A WARM FRONT MOVES
THROUGH. RAIN WILL TAPER TONIGHT BUT THE LOW LEVELS WILL REMAIN
MOIST.

KSEA...SOUTH WIND 6-10 KNOTS...INCREASING TO 10-15 KNOTS THIS
AFTERNOON AND EVENING. RAIN WILL TAKE AWHILE TO DEVELOP AS THE
TERMINAL WILL BE A BIT SHADOWED BY THE OLYMPICS UNTIL LATE
AFTERNOON. SCHNEIDER

&&

.MARINE...A WARM FRONT WILL BRING SMALL CRAFT ADVISORY SOUTHERLY
WINDS TO MOST WATERS TODAY FOLLOWED BY MODERATE ONSHORE FLOW TONIGHT
AND SATURDAY. WEAK HIGH PRESSURE WILL BE OVER THE WATERS ON SUNDAY.
SOUTHERLY GRADIENTS WILL INCREASE AGAIN SUNDAY NIGHT AND MONDAY AS
ANOTHER FRONTAL SYSTEM APPROACHES AND MOVES THROUGH. SCHNEIDER

&&

.SEW WATCHES/WARNINGS/ADVISORIES...
WA...NONE.
PZ...SMALL CRAFT ADVISORIES ARE IN EFFECT FOR ALL WATERS EXCEPT
     THE CENTRAL STRAIT OF JUAN DE FUCA.

     SMALL CRAFT ADVISORY FOR ROUGH BAR UNTIL 4 AM PST SATURDAY
     FOR THE GRAYS HARBOR BAR.
