AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SEATTLE WA
330 AM PDT WED JUN 17 2015

.SYNOPSIS...A TYPICAL ONSHORE FLOW PATTERN WILL BRING MORNING CLOUDS
AND PARTIAL AFTERNOON SUNSHINE TODAY AND THURSDAY. A WEAK UPPER
LEVEL TROUGH BRUSHING WESTERN WASHINGTON COULD BRING SOME SHOWERS TO
THE AREA LATE THURSDAY NIGHT THROUGH FRIDAY EVENING. HIGH PRESSURE
WILL BUILD BACK IN TO THE AREA OVER THE WEEKEND FOR SUNNIER AND
WARMER WEATHER. ANOTHER WEAK SYSTEM COULD BRING A FEW SHOWERS AND
COOLER TEMPERATURES TO THE REGION EARLY NEXT WEEK.

&&

.SHORT TERM...SATELLITE STRATUS/FOG PRODUCT IMAGERY IS PARTIALLY
OBSCURED BY HIGH CLOUDS PASSING THE AREA. BUT WITH SOME OBS
AVAILABLE IT APPEARS STRATUS IS PATCHY AND GENERALLY FORMING IN
PLACE...ESPECIALLY COAST...STRAIT...AND THE SW INTERIOR. TEMP/DEW
POINT SPREADS ARE CLOSING IN SO IT SEEMS REASONABLE THAT STRATUS
COULD FILL IN JUST ABOUT ANYWHERE...THOUGH NOT AS SOLIDLY AS
YESTERDAY. EXPECT A PARTLY TO MOSTLY CLOUDY START TO THE DAY...THEN
THE LOW CLOUDS MIX OUT WITH FILTERED SUNSHINE DUE HIGH CLOUDS OVER
THE REGION. HIGHS SHOULD REACH THE LOW 70S INLAND...AND 60S COAST
AND STRAIT.

MODELS ARE A LITTLE FASTER WITH THE CUT OFF WAVE BECOMING RETRAINED
IN SW FLOW THANKS TO THE PARENT LOW OFF THE B.C. COAST. MID/HIGH
CLOUDS INCREASE THURSDAY WHICH WILL PROBABLY INHIBIT MUCH IN THE WAY
OF LOW CLOUDS BUT WILL STILL BUT A LID ON HIGHS WHICH WILL MOSTLY
BE IN THE 60S TO AROUND 70.

MOS GUIDANCE AND THE WRF GFS INDICATE ENOUGH MOISTURE WITH THE
INITIAL SURGE OF MID LEVEL MOISTURE COULD BE ENOUGH TO TRIGGER SOME
MOUNTAIN SHOWERS SO LOW POPS ARE IN THE FORECAST FOR THE HIGHER
TERRAIN. DEEPER MOISTURE ARRIVES THURSDAY NIGHT AND FRIDAY MORNING
WHICH WILL BRING THE BEST SHOT OF MAINLY LIGHT RAIN TO MOST OF WRN
WA...THE FIRST MEASURABLE RAIN FOR SOME AREAS SINCE JUNE 2ND. THE
WAVE HAS LITTLE DYNAMIC SUPPORT BUT IT DOES HAVE DEEP MOISTURE
FIELDS ACCORDING TO MODELS GIVEN ITS ORIGINATION NEAR THE
SUBTROPICS. QPF AMOUNTS AROUND THE INTERIOR LOWLANDS WILL BE
PROBABLY BE MEAGER WITH GENERALLY LESS THAN A TENTH. SOME MOUNTAIN
SPOTS AND FOOTHILLS COULD SEE A QUARTER INCH. MESO MODELS INDICATE A
POSSIBLE PUGET SOUND CONVERGENCE ZONE FRIDAY AFTERNOON INTO AT LEAST
FRIDAY EVENING. THIS COULD PROVIDE LOCALLY HIGHER RAIN AMOUNTS
AROUND SNOHOMISH/KING COUNTIES EAST TO THE CENTRAL FOOTHILLS AND
CASCADES. THE CONVERGENCE ZONE SHOULD WEAKEN AND DISSIPATE BY LATE
FRIDAY NIGHT. HIGHS FRIDAY WILL ONLY BE IN THE 60S.

.LONG TERM...VIRTUALLY ALL MODELS AGREE THAT THE SHORT WAVES PUSHES
RAPIDLY EWD ON SATURDAY. AFTER SOME RESIDUAL MORNING CLOUDS...EXPECT
SUNSHINE TO RETURN WITH HIGHS WARMING INTO THE LOWER 70S. MOST
GLOBAL MODELS SHOW RIDGING ON SUNDAY AND A WEAK THERMALLY INDUCED
TROUGH TO THE S OF WA OVER OREGON/CA. IT SHOULD BE DRY WITH NLY FLOW
AND RISING HEIGHTS. HIGHS SHOULD REACH THE MID TO UPPER 70S...WITH
SOME SPOTS NEAR 80 IN THE FOOTHILLS AND SW INTERIOR.

LONG RANGE MODELS HAVE TRENDED TOWARD BREAKING DOWN THE WEAK RIDGE
AND BRINGING A WEAK SHORT WAVE THROUGH THE AREA MONDAY INTO TUESDAY.
THE GFS/ECMWF/CANADIAN ALL HANDLE THE TIMING AND OTHER DETAILS
DIFFERENTLY BUT GENERALLY AGREE ON A WEAK TROUGH OR CLOSED LOW NEAR
THE AREA. THIS SHOULD INDUCE ONSHORE FLOW AND BRING A RENEWED THREAT
OF SHOWERS TO PARTS OF THE AREA...ESPECIALLY NORTH AND MOUNTAINS.
KEPT CENTRAL PUGET SOUND SWD DRY FOR NOW GIVEN THAT SOME MODELS ARE
PRETTY FAR N WITH THE LOW AND PRECIPITATION MIGHT NOT SPREAD AS FAR
S AS SOME MODELS IMPLY. WILL NEED TO WATCH MODEL TRENDS AND ADJUST
THE FORECAST TO SHIFT POPS FURTHER SWD IF NECESSARY. HIGHS WILL COOL
OFF EARLY NEXT WEEK TO THE 60S AND LOW 70S DEPENDING ON CLOUD COVER
AND RAIN POTENTIAL.  MERCER

&&

.AVIATION...SOUTHWEST FLOW ALOFT OVER WESTERN WASHINGTON WILL
CONTINUE THROUGH TONIGHT. ONSHORE SURFACE FLOW WILL CONTINUE TODAY.
THE AIR MASS IS STABLE AND DRY EXCEPT FOR AREAS OF MARINE STATUS
MAINLY NEAR THE COAST AND PARTS OF PUGET SOUND. THE AREAS OF STRATUS
SHOULD FILL IN FOR THE MOST PART THIS MORNING, BUT MAY BE LESS
EXTENSIVE THAN IT WAS YESTERDAY. MOST OF THE CEILINGS WILL BE AROUND
1-1.5K FEET. THE STRATUS WILL DISSIPATE BACK TO THE COAST BY NOON
AND THEN REFORM AGAIN OVERNIGHT.

KSEA...STRATUS SHOULD BRING CEILINGS AROUND 1K FT BY ABOUT 12 OR 13Z
AND THEN DISSIPATE BY 17Z OR SO. LIGHT SOUTH WIND THIS MORNING
TURNING WNW BY LATE AFTERNOON. 13

&&

.MARINE...MODERATE TO STRONG ONSHORE FLOW WILL CONTINUE INTO THE
WEEKEND. SMALL CRAFT ADVISORY WESTERLIES ARE LIKELY EACH EVENING IN
THE STRAIT THROUGH FRIDAY NIGHT WITH LOW END GALES POSSIBLE. 13
