AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SEATTLE WA
900 PM PDT MON JUN 11 2012

.SYNOPSIS...A WEAK FRONT OVER THE WASHINGTON COASTAL WATERS WILL
MOVE INLAND OVERNIGHT AND WILL BE FOLLOWED BY AN UPPER LEVEL TROUGH
TUESDAY THROUGH EARLY WEDNESDAY. THESE FEATURES WILL BRING
CLOUDS...COOLER TEMPERATURES...AND SOME LIGHT RAIN TO THE AREA.
ANOTHER UPPER LEVEL TROUGH WILL BRING SHOWERS TO THE AREA WEDNESDAY
NIGHT AND THURSDAY.  HIGH PRESSURE WILL RETURN FRIDAY FOR DRY AND
WARMER WEATHER. UNSETTLED WEATHER WILL LIKELY RETURN TO THE AREA
NEXT WEEKEND.

&&

.SHORT TERM...THE RIDGE OF HIGH PRESSURE ALOFT THAT BROUGHT A VERY
NICE AND WARM DAY TO WESTERN WASHINGTON TODAY HAS SHIFTED EAST OF
THE CASCADES. A WEAK FRONT THAT IS MOVING THROUGH THE COASTAL WATERS
IS BRINGING THICKENING CLOUDS TO THE AREA THIS EVENING AND SOME VERY
LIGHT RAIN IS BEING REPORTED ON THE NORTH COAST AND ALONG THE STRAIT
OF JUAN DE FUCA. THE INITIAL SHOT OF LIGHT RAIN IS FALLING FROM HIGH
BASED CLOUDS...SO LITTLE IN THE WAY OF RAINFALL SHOULD BE EXPECTED
THIS EVENING.

THE 18Z AND RECENTLY RECEIVED 00Z NAM12 SOLUTIONS ARE THE DRIEST OF
THE MODEL RUNS TODAY SHOWING LITTLE MORE THAN A CHANCE OF RAIN OVER
THE INTERIOR LATER TONIGHT THROUGH TUESDAY NIGHT. IN GENERAL...NAM12
TIME HEIGHT PRODUCTS FOR SEATTLE APPEAR TO HAVE THE RIGHT IDEA IN
BRINGING A SHEARED UPPER PORTION OF THE FRONT THROUGH THE AREA THIS
EVENING FOR A FEW SPRINKLES...FOLLOWED BY THICKENING AND LOWERING
CLOUDS CLOUDS AND INCREASING MOISTURE IN ONSHORE FLOW LATE TONIGHT
THROUGH TUESDAY AS THE REMNANTS OF THE LOW LEVEL FRONT GETS LIFTED
BY A PASSING WEAK UPPER LEVEL SHORT WAVE TROUGH NOW CENTERED NEAR
45N 140W. THE 18Z GFS AND 12Z ECMWF SOLUTIONS ARE WETTER AND
MODEL OUTPUT STATISTICS FROM THE GFS AND LAST NIGHTS ECMWF SHOW
RATHER HIGH POPS FOR THE AREA. CURRENT FORECASTS ARE GENERALLY A
COMPROMISE BETWEEN THE VARIOUS SOLUTIONS. THE NAM MOS IS WARM IN THE
INTERIOR FOR TUESDAY GIVING 70 TO SEATTLE WHILE THE RAW WRFGFS
SOLUTIONS FAVOR LOWER 60S. AGAIN...CURRENT FORECASTS ARE A
COMPROMISE.

ONSHORE FLOW WILL KEEP A COOL AND MOIST MARINE AIR MASS OVER THE
AREA TUESDAY NIGHT INTO WEDNESDAY. THERE WILL STILL BE A CHANCE OF
SHOWERS ALONG WITH A POSSIBLE PUGET SOUND CONVERGENCE ZONE. IF THE
CONVERGENCE ZONE FORMS...PRECIPITATION AMOUNTS MAY BE ENHANCED IN
THE FAVORED SNOHOMISH/KING COUNTY AREAS. HIGH TEMPERATURES ON
WEDNESDAY WILL LIKELY COOL FURTHER WITH HIGHS IN THE UPPER 50S COAST
AND LOWER TO MID 60S INLAND.

ANOTHER UPPER TROUGH WILL SKIRT BY THE AREA MAINLY TO THE NORTH ON
THURSDAY. MODELS HAVE NOT BEEN VERY CONSISTENT WITH DEPTH OF THIS
TROUGH MAKING IT DIFFICULT TO TELL IF SHOWERS WILL MAKE IT INTO
WESTERN WASHINGTON. THE 12Z ECMWF IS MOSTLY DRY AND THE GFS/NAM
BOTH HAVE SOME SPOTTY QPF. SOME PREVIOUS RUNS HAD MORE QPF THAN
CURRENTLY SHOWN BY MODELS. LOW POPS ARE IN THE FORECAST FOR A CHANCE
OF SHOWERS. ONSHORE FLOW WILL CONTINUE WITH HIGH TEMPERATURES STILL
STUCK IN THE 60S. ALBRECHT/MERCER

.LONG TERM...PREVIOUS LONG TERM DISCUSSION FOLLOWS...MODELS
GENERALLY AGREE ON BRIEF RIDGING BY FRIDAY WITH A PERIOD OF DRY AND
WARMER WEATHER. DECIDED TO PULL POPS AND BUMP HIGHS UP CLOSER TO
AVERAGE IN THE LOWER 70S. DRY WEATHER WILL LIKELY PERSIST INTO
FRIDAY NIGHT THEN A CHANGE IN THE PATTERN IS POSSIBLE.

THE GFS/ECMWF CONTINUE TO VARY FROM RUN TO RUN BEYOND FRIDAY. THE
GFS INDICATES A PARTIALLY DRY WEEKEND WITH A TROUGH POSSIBLY
BRINGING SOME SHOWERS BY SUNDAY. A MORE VIGOROUS TROUGH IS SHOWN BY
THE ECMWF WHICH COULD RESULT IN SHOWERS MUCH OF THE WEEKEND. DECIDED
TO KEEP THE BROAD BRUSH CHANCE OF SHOWERS FOR NOW.  MERCER

&&

.AVIATION...A WEAK UPPER TROF OFFSHORE WILL MOVE OVER WRN WA
OVERNIGHT. CONTINUED WLY FLOW ALOFT AND WEAK LOW LEVEL ONSHORE FLOW.

THERE WERE AREAS OF -RA OVER THE NW PART OF THE FORECAST AREA AT
THIS TIME. ALSO...VFR CONDITIONS PREVAILED WITH CIGS RUNNING AT OR
ABOVE 9K FT. EXPECT CIGS TO GRADUALLY LOWER TONIGHT. BY 1200 UTC...
CIGS SHOULD BE MAINLY IN THE 1-3K FT RANGE OVER THE COAST /ALONG
WITH AREAS OF VSBYS OF 3-5SM/ AND IN THE 4-6K FT RANGE OVER THE
INTERIOR. -RA OR -DZ WILL ALSO BECOME MORE WIDESPREAD OVERNIGHT.

KSEA...VFR CONDITIONS ARE EXPECTED TO PREVAIL OVERNIGHT. MVFR CIGS
/2-3K FT/ WILL LIKELY HOLD OFF UNTIL AFTER 1200 UTC. WINDS WILL
REMAIN LIGHT TONIGHT.

&&

.MARINE...A 1020 MB HIGH ON THE WASHINGTON COAST WILL DISSIPATE
OVERNIGHT... ALLOWING A WEAK COLD FRONT TO APPROACH FROM THE W. THIS
FRONT WILL FALL APART AS IT MOVES ONSHORE TUE. ONSHORE FLOW WILL
STRENGTHEN TUE AND PERSIST THROUGH WED DUE TO BUILDING HIGH PRES
OFFSHORE. ONSHORE FLOW WILL WEAKEN ON THU.

&&

.SEW WATCHES/WARNINGS/ADVISORIES...
WA...NONE.
PZ...SMALL CRAFT ADVISORY UNTIL 11 PM PDT TONIGHT FOR THE
      CENTRAL AND EASTERN STRAIT OF JUAN DE FUCA.
