AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SEATTLE WA
903 AM PDT SAT JUN 8 2013

.SYNOPSIS...A WEAK UPPER LEVEL RIDGE WILL KEEP WESTERN WASHINGTON
DRY THIS WEEKEND...WHILE CONTINUING ONSHORE FLOW WILL KEEP
TEMPERATURES NEAR NORMAL. AN UPPER LEVEL LOW WILL MOVE OVER THE
REGION NEXT WEEK BRINGING CLOUDS...COOLER TEMPERATURES...AND A
CHANCE OF SHOWERS.

&&

.SHORT TERM...WEAK RIDGING OVER THE PAC NW WILL KEEP WESTERN
WASHINGTON DRY TODAY. LOW LEVEL ONSHORE FLOW CONTINUES WITH
TEMPERATURES CLOSE TO NORMAL...HIGHS IN THE 60S ALONG THE COAST AND
MID 60S TO LOWER 70S INTERIOR. THERE IS A MIXED BAG OF CLOUDS ACROSS
THE REGION WITH LOW LEVEL STRATUS OVER THE CENTRAL SOUND AND A MID
DECK BRUSHING THE NORTH. THE COAST AND FAR SW INTERIOR ARE MOSTLY
SUNNY. BUT ALL AREAS SHOULD SEE SOME SUNBREAKS THIS AFTERNOON.

THE FORECAST FOR SUNDAY LOOKS PRETTY SIMILAR TO TODAY...PERHAPS A
FEW LESS MORNING CLOUDS IN THE INTERIOR. ON MONDAY AN UPPER LEVEL
LOW WILL DROP S/SE FROM B.C. THIS LOW WILL THEN DIG OFFSHORE MON
NIGHT. MODELS SHOW AN INCREASE IN ONSHORE FLOW FOR MORE CLOUDS AND A
FEW SHOWERS...MAINLY AFFECTING THE COAST. 33

.LONG TERM...PREVIOUS DISCUSSION...ECMWF AND GFS REMAIN IN GOOD
AGREEMENT FOR NEXT WEEK WITH THE UPPER LEVEL LOW REMAINING JUST
OFFSHORE OF THE NORTH WA COAST ON TUESDAY...THEN MOVING OVER W WA
WEDNESDAY...E WA THURSDAY...AND FARTHER E ON FRIDAY...LEAVING W WA
UNDER SOMEWHAT MOIST NW FLOW ALOFT. TUESDAY WILL HAVE A LOW CHANCE
OF SHOWERS...MAINLY FOR WESTERN AREAS. BEST SHOWER DAYS WILL
PROBABLY BE WEDNESDAY AND THURSDAY WHILE THE LOW IS OVERHEAD.
CURRENT POPS MAY BE A LITTLE LOW FOR WEDNESDAY AND THURSDAY...WITH
GUIDANCE IN THE HIGH CHANCE RANGE. THE POSSIBILITY OF THUNDERSTORMS
ON WEDNESDAY WILL EVENTUALLY HAVE TO BE ADDRESSED. MAX TEMPS WILL BE
IN THE UPPER 50S TO MID 60S...FORECASTS LOOK GOOD BUT WARMING ON
THURSDAY MAY BE A LITTLE PRE-MATURE. WILL LEAVE THE EXTENDED PERIODS
TO THE DAY SHIFT. KAM

&&

.AVIATION...MODERATE WESTERLY FLOW ALOFT WILL CONTINUE TODAY AND
TONIGHT. AT THE SURFACE WEAK TO MODERATE ONSHORE FLOW WILL CONTINUE.
AIR MASS IS STABLE WITH AREAS OF LOW LEVEL MOISTURE BUT ALSO LARGE
CLEAR AREAS ON THE COAST...MOUNTAINS...AND SOUTHWEST.

CEILINGS ARE MAINLY VFR 3K-5K FT WITH SOME MVFR 2K-3K FT OVER
CENTRAL PUGET SOUND. ONSHORE GRADIENTS ARE A BIT WEAKER TODAY WHICH
SHOULD ALLOW CLOUDS TO BREAK UP TODAY FOR AN OVERALL IMPROVING
TREND. SOME LOW CLOUDS WILL LIKELY REFORM AFTER MIDNIGHT TONIGHT BUT
NOTHING TOO WIDESPREAD.

KSEA...LIGHT NORTH WIND WILL INCREASE TO 6-10 KT THIS AFTERNOON.
SCHNEIDER/CHB

&&

.MARINE...ONSHORE FLOW OF VARYING STRENGTH WILL CONTINUE INTO EARLY
NEXT WEEK. SMALL CRAFT ADVISORY WEST WINDS ARE EXPECTED EACH EVENING
IN THE STRAIT OF JUAN DE FUCA. THESE WINDS WILL SPILL INTO ADMIRALTY
INLET AND THE WESTERN PART OF THE NORTHERN INLAND WATERS AT TIMES.

FOR NOW THE STRONGEST ONSHORE FLOW LOOKS LIKE SUNDAY NIGHT WITH
GALES FORCE WINDS LIKELY IN THE STRAIT AS WELL AS SMALL CRAFT
ADVISORY NORTHWEST WINDS FOR THE COASTAL WATERS. HOWEVER...MARGINAL
GALES ARE NOT OUT OF THE QUESTION ANY EVENING IN THE STRAIT FOR THE
NEXT FEW DAYS. THERE WILL ALSO BE SOME 10 OR 11 FOOT WEST SWELL OVER
THE OUTER COASTAL WATERS TODAY. SCHNEIDER/CHB

&&

.SEW WATCHES/WARNINGS/ADVISORIES...
WA...NONE.
