AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SEATTLE WA
915 AM PDT SAT MAR 14 2015

.SYNOPSIS...A FRONTAL SYSTEM WILL PRODUCE RAIN TODAY. RAIN WILL
TAPER FROM THE NORTHWEST TONIGHT THEN SPREAD NORTH AGAIN FROM THE
SOUTH ON SUNDAY. UNSETTLED WEATHER WILL CONTINUE MONDAY THROUGH MID
WEEK WITH A THREAT OF SHOWERS. DRIER WEATHER MAY DEVELOP TOWARD THE
END OF THE WEEK.

&&

.SHORT TERM...WIND AND RAIN HAS DIMINISHED IN THE LAST HOUR ON THE
COAST AS A FRONT HAS PASSED. THERE WILL BE AT LEAST A FEW MORE HOURS
OF PRETTY GOOD RAINFALL OVER INLAND AREAS. AMOUNTS SO FAR ARE LESS
THAN AN INCH OVER THE LOWLANDS AND 1-2 INCHES IN THE MOUNTAINS. HIGH
TEMPERATURES TODAY WILL NOT BE MUCH HIGHER THAN THEY ARE RIGHT
NOW...IN THE 50S.

THE FRONT WILL EXIT TO THE SOUTHEAST THIS EVENING. ANOTHER WAVE WILL
MOVE INTO THE AREA FROM THE SOUTHWEST TONIGHT AND SUNDAY. RAIN WILL
SPREAD NORTH SUNDAY MORNING THEN TURN MORE SHOWERY SUNDAY NIGHT AS
AN UPPER LEVEL TROUGH PASSES. MONDAY WILL STILL HAVE RESIDUAL
SHOWERS. THE GFS AND NAM ARE IN GOOD AGREEMENT ON BOTH THE BROAD
IDEAS AND THE DETAILS...WHICH IS A PLEASANT CHANGE FROM PREVIOUS
MODEL RUNS. HIGHS WILL BE IN THE 50S SUNDAY AND MONDAY. BURKE

.LONG TERM...PREVIOUS DISCUSSION...THE EXTENDED FORECAST REMAINS UP
IN THE AIR WITH A WIDE RANGE OF SOLUTIONS. PLACEMENT AND TIMING OF
EVEN THE LARGER SCALE FEATURES IS HARD TO PIN DOWN. SOME MODELS
BRING ANOTHER WEAK TROUGH INTO THE AREA TUESDAY AND POSSIBLY
WEDNESDAY SO A CHANCE OF SHOWERS WILL STAY IN THE FORECAST FOR NOW.
THURSDAY IS A TOUGH CALL AS DRY WEATHER IS CURRENTLY ADVERTISED. THE
ECMWF NOW SHOWS WET WEATHER OVER THE AREA AND OTHER MODELS JUST SHOW
A BRUSH BY TROUGH. SINCE THERE IS NO AGREEMENT AT THIS POINT...THE
DRY FORECAST FOR THURSDAY AND FRIDAY WILL REMAIN AS IS. HOPEFULLY
THE 12Z MODELS COME INTO BETTER AGREEMENT AND THE NEXT SHIFT CAN
MAKE ADJUSTMENTS. HIGHS NEXT WEEK WILL BE ABOVE NORMAL IN THE UPPER
50S AND 60S.

&&

.HYDROLOGY...SO FAR LESS THAN TWO INCHES OF RAIN HAS FALLEN IN THE
SKOKOMISH RIVER BASIN. GIVEN DRY ANTECEDENT CONDITIONS IT WOULD
PROBABLY TAKE MORE THAN THREE INCHES TO MAKE THE SKOKOMISH FLOOD.
THIS WOULD REQUIRE 6-8 MORE HOURS OF HEAVY RAIN WHICH SEEMS UNLIKELY
TODAY.

FLOODING IS UNLIKELY ON AREA RIVERS FOR THE NEXT SEVEN DAYS. BURKE

&&

.AVIATION...A WARM FRONT OVER W WA THIS MORNING WILL MOVE E TODAY
AND WEAKEN. A COLD FRONT APPROACHING FROM THE W WILL MOVE OVER THE
COASTAL WATERS THIS AFTERNOON AND OVER W WA EARLY THIS EVENING. THE
AIR MASS IS MOIST AND STABLE WITH WIDESPREAD RAIN. CIGS ARE MOSTLY
MVFR WITH LOCAL IFR CIGS THROUGH EARLY EVENING. THERE WILL ALSO BE
AREAS OF MVFR VISIBILITY 3-5SM IN -RA BR. CIGS SHOULD RISE A LITTLE
BEHIND THE COLD FRONT THIS EVENING. MODERATE S LOW LEVEL FLOW ACROSS
W WA WILL PRODUCE GUSTY S SURFACE WINDS.

KSEA...MVFR CIGS WILL PREDOMINATE TODAY WITH OCCASIONAL IFR CIGS.
VISIBILITY WILL DROP TO 4-6SM AT TIMES IN -RA BR. SURFACE WINDS WILL
REMAIN S 5-15 KT THROUGH 19Z THEN RISE TO 15G25KT AFTER ABOUT 19Z.
13/KAM

&&

.MARINE...A COLD FRONT APPROACHING FROM THE W WILL MOVE OVER THE
COASTAL WATERS THIS AFTERNOON AND OVER THE W WA INTERIOR EARLY THIS
EVENING. THE COASTAL WATERS AND EAST ENTRANCE WIND SPEEDS THAT WERE
JUST UNDER GALE FORCE THIS MORNING HAVE DIMINISHED SLIGHTLY BY MID
MORNING AND SHOULD CONTINUE TO STAY IN THE SMALL CRAFT ADVISORY
RANGE LATE THIS MORNING.

WINDS WILL SHIFT TO SW TO W JUST AHEAD OF AND BEHIND THE APPROACHING
COLD FRONT THIS AFTERNOON. THIS WILL RESULT IN A PERIOD OF HIGH END
SCA WEST WINDS IN THE CENTRAL AND E STRAIT OF JUAN DE FUCA THIS
AFTERNOON AND EVENING. THE ADJOINING WATERS OVER ADMIRALTY INLET AND
THE N INLAND WATERS WILL SEE SOME SCA WINDS THIS AFTERNOON AND
EVENING AS WELL.

A SURFACE HIGH WILL BUILD OVER B.C. TONIGHT...ALLOWING OFFSHORE FLOW
TO DEVELOP. BOTH THE ECMWF AND GFS HAVE A LOW APPROACHING THE AREA
FROM THE SW SUNDAY MORNING BUT THAT IS ABOUT ALL THE MODELS AGREE
ON. AFTER THAT THE MODELS DON'T AGREE MUCH AND CONFIDENCE IS LOW.
