AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SEATTLE WA
315 PM PDT TUE MAY 15 2012

.SYNOPSIS...ONSHORE FLOW WILL CONTINUE TONIGHT AND WEDNESDAY. THIS
WILL BRING COOLER WEATHER AND CLOUDS AT TIMES. AN UPPER LEVEL TROUGH
WILL KEEP THE WEATHER COOL WITH A CHANCE OF SHOWERS THURSDAY AND
FRIDAY. WEAK HIGH PRESSURE WILL BRING DRY AND SOMEWHAT WARMER
WEATHER SATURDAY. WETTER WEATHER WILL DEVELOP EARLY NEXT WEEK AS A
SERIES OF FRONTS MOVE THROUGH.

&&

.SHORT TERM...AN UPPER TROUGH WILL MOVE OVERHEAD TONIGHT AND
WEDNESDAY. THIS WILL INCREASE THE ONSHORE FLOW AND DEEPEN THE MARINE
LAYER AT BIT. THE EXPECTATION IS THAT STRATUS WILL REDEVELOP TONIGHT
AND COVER MOST OF THE LOWLANDS BY WEDNESDAY MORNING WITH PARTIAL
AFTERNOON SUNSHINE. HOWEVER...THERE IS A DISTINCT LACK OF ANY
STRATUS...EVEN AT THE COAST...AT THIS TIME AND THE FORECAST OF
STRATUS FILLING BACK IN TONIGHT MIGHT BE IN JEOPARDY. HIGHS WILL
COOL TO NEAR NORMAL ALL AREAS WEDNESDAY.

A BROAD UPPER TROUGH WILL REMAIN OVER THE AREA ON THURSDAY...
SHIFTING INLAND ON FRIDAY. THERE MIGHT BE A FEW SHOWERS IN THIS
PATTERN. HIGHS WILL BE NEAR TO SLIGHTLY BELOW NORMAL WITH MORNING
CLOUDS AND SOME AFTERNOON SUNSHINE EACH DAY. SCHNEIDER

.LONG TERM...A WEAK UPPER RIDGE WILL BRIEFLY BUILD OVER THE AREA ON
SATURDAY FOR A DRY DAY WITH A BIT OF WARMING. LONG RANGE MODELS ARE
NOW MUCH WETTER FOR THE SUNDAY THROUGH TUESDAY PERIOD...SHOWING A
PROGRESSIVE PATTERN WITH A SERIES OF FRONTS MOVING THROUGH.

POPS FOR THE SUNDAY THROUGH TUESDAY PERIOD WERE INCREASED BUT NOT
TOO DRASTICALLY FOR NOW. THERE ARE THE USUAL MODEL TIMING
DIFFERENCES WITH THE INDIVIDUAL FEATURES AND STILL MUCH UNCERTAINLY
ABOUT HOW WET IT WILL ACTUALLY BE. SCHNEIDER

&&

.AVIATION...THE PATTERN OF SOUTHWEST WIND ALOFT WITH ONSHORE SURFACE
FLOW WILL CONTINUE THROUGH WEDNESDAY. AIR MASS IS CURRENTLY STABLE
AND DRY EXCEPT FOR THIN HIGH CLOUDS. AT THE MOMENT THERE IS ZERO
STRATUS BUT THE FORECAST IS FOR STRATUS TO FORM ALONG THE COAST THEN
FLOOD INLAND OVERNIGHT. PARTIAL CLEARING IS POSSIBLE OVER INLAND
AREAS WEDNESDAY AFTERNOON. CEILINGS UNDER THE STRATUS WILL BE NEAR
1K FT WITH LOCAL FOG REDUCING VISIBILITY TO 3-5SM.

KSEA...NORTHWEST WIND 5-8 KT WILL PERSIST THIS EVENING. WIND WILL
BECOME SW 5-8 KT LATE TONIGHT AND IFR STRATUS IS LIKELY AFTER 12Z.

&&

.MARINE...NORTHWESTERLY FLOW WILL CONTINUE OVER THE COASTAL WATERS
THROUGH WEDNESDAY AND PROBABLY BEYOND. WINDS WILL BE IN THE 15-25
KNOT RANGE TONIGHT AND WEDNESDAY WITH THE OUTER WATERS PERHAPS
SEEING 20-30 KT. THE SMALL CRAFT ADVISORY REMAINS IN EFFECT THERE
THROUGH WEDNESDAY WITH EXTENSIONS LIKELY. THERE SHOULD ALSO BE
ENOUGH FLOW WITH THE MARINE PUSH DEVELOPING FOR SMALL CRAFT ADVISORY
WINDS TO RE-DEVELOP IN THE CENTRAL AND EAST STRAIT THIS AFTERNOON
AND EVENING. THERE IS STILL A CHANCE FOR A GALE THERE TONIGHT BUT
HAVE KEPT WINDS AT 20-30 KT FOR THE AFTERNOON FORECAST.

HAVE ALSO PUT UP SMALL CRAFT ADVISORIES FOR ADMIRALTY INLET AND THE
NORTHERN INLAND WATERS TONIGHT...BASICALLY FOR OUTFLOW FROM THE
STRAIT. PUGET SOUND SHOULD GET SW WINDS AND LOW STRATUS BY WEDNESDAY
MORNING.

MODELS SHOW A DIURNAL PATTERN TO THE FLOW THROUGH THE STRAIT EACH
DAY THIS WEEK. WESTERLY WINDS WILL PICK UP TO 15 TO 30 KT DURING THE
LATE AFTERNOON AND NIGHTTIME HOURS. THERE IS A SLIGHT POSSIBILITY OF
LOW END WESTERLY GALE DURING THIS PERIOD. THE PATTERN COULD CHANGE
BY SUNDAY AS MODELS SHOW A FRONT APPROACHING THE COAST THEN. CHB

&&

.SEW WATCHES/WARNINGS/ADVISORIES...
WA...NONE.
PZ...SMALL CRAFT ADVISORY COAST..CENTRAL AND EAST STRAIT...ADMIRALTY
     INLET...AND NORTHERN INLAND WATERS.
