AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SEATTLE WA
840 PM PDT SUN JUN 8 2014

.SYNOPSIS...STRONG ONSHORE FLOW TONIGHT WILL INCREASE LOW LEVEL
MOISTURE AND BRING A CHANCE OF LIGHT RAIN AND DRIZZLE THROUGH
MONDAY. A WEAK WEATHER SYSTEM WILL BRING A CHANCE OF LIGHT RAIN
TUESDAY. MOSTLY DRY WEATHER IS EXPECTED BETWEEN SYSTEMS WEDNESDAY.
ANOTHER SYSTEM WILL PROBABLY BRING SOME RAIN THURSDAY. CONDITIONS
WILL BE COOL AND MOSTLY CLOUDY MOST OF NEXT WEEK.

&&

.SHORT TERM...LOW LEVEL ONSHORE FLOW IS A BIT STRONGER THIS EVENING.
IT WILL CONTINUE TO STRENGTHEN TONIGHT IN RESPONSE TO A PASSING
UPPER SHORT WAVE. THIS SHOULD ALLOW COASTAL STRATUS TO FILL IN OVER
THE INTERIOR LATER TONIGHT AND MONDAY MORNING. IT COULD ALSO BRING
SOME DRIZZLE OR SPOTTY LIGHT RAIN LATER TONIGHT AND MONDAY MORNING.
THE LOW LEVELS DRY A BIT MONDAY AFTERNOON AND THERE MIGHT BE SOME
SUNBREAKS OVER THE INTERIOR. HIGHS WILL COOL BACK TO NEAR NORMAL
MONDAY.

A WEAK UPPER TROUGH WILL CROSS THE AREA ON TUESDAY. THIS WILL KEEP A
CHANCE OF RAIN IN THE FORECAST. LOW LEVEL ONSHORE FLOW WILL PERSIST
AND IT SHOULD BE A MOSTLY CLOUDY DAY WITH HIGHS SLIGHTLY BELOW
NORMAL. A SHORT WAVE UPPER RIDGE WILL TRANSIT THE AREA ON WEDNESDAY.
NO PRECIPITATION IS EXPECTED DURING THIS TIME BUT IT WILL BE ANOTHER
DAY OF MORNING CLOUDS AND PARTIAL AFTERNOON CLEARING WITH CONTINUED
LOW LEVEL ONSHORE FLOW. SCHNEIDER

.LONG TERM...PREVIOUS DISCUSSION...A DEEPER UPPER TROUGH SWINGS
THROUGH ON THURSDAY. THIS IS LIKELY TO BRING A LITTLE RAIN TO MOST
AREAS. THE SNOW LEVEL WILL FALL TO 6000 FEET OR SO. THE TROUGH TAKES
MOST OF FRIDAY TO MOVE OUT OF THE AREA AND THEN ZONAL FLOW ALOFT
TAKES OVER. THIS FLOW WILL ALLOW ANOTHER WEAK SYSTEM TO ARRIVE
SATURDAY...AND THIS ONE LINGERS INTO SUNDAY. THE PATTERN IS
GENERALLY COOL WITH HIGHS IN THE 60S...MOSTLY CLOUDY SKIES...AND A
CHANCE OF SHOWERS EACH DAY. BURKE

&&

.AVIATION...WESTERLY FLOW ALOFT WILL PREVAIL THROUGH MONDAY. A WEAK
UPPER LEVEL TROUGH WILL MOVE ACROSS SOUTHERN B.C. TONIGHT...BRUSHING
W WA IN THE PROCESS. THE TROUGH WILL BE E OF THE CASCADES BY 12Z
MONDAY. LOW LEVEL ONSHORE FLOW WILL CONTINUE. THE TROUGH HAS
PRODUCED STRONGER ONSHORE FLOW AND HAS BROUGHT A BIT MORE LOW AND
MID LEVEL MOISTURE OVER W WA. THE MARINE LAYER OVER WESTERN
WASHINGTON WILL DEEPEN TO AROUND 6000 FT TONIGHT.

WIDESPREAD STRATUS IS EXPECTED TO FORM AGAIN OVERNIGHT WITH MAINLY
MVFR CIGS BELOW 2000 FEET. THERE COULD BE SOME SPOTTY IFR CIGS. THE
MARINE LAYER SHOULD BE DEEP ENOUGH FOR STRATUS TO PUSH UP OVER THE
CASCADES. CIGS HAVE ALREADY DROPPED TO IFR ON THE COAST AND MVFR
CIGS SHOULD FORM OVER THE INTERIOR AROUND 08Z. CIGS SHOULD LIFT
GRADUALLY TO 3000-4000 FEET 18Z-21Z WITH MAINLY BKN CIGS CONTINUING
THROUGH 00Z.

KSEA...VFR CONDITIONS EXPECTED THROUGH 07Z. A BKN040-050 LAYER HAS
FORMED OVER THE CENTRAL SOUND AND IT LOOKS LIKE IT WILL MOVE OVER
KSEA BY 05Z. STRATUS WILL FORM LATE TONIGHT WITH CIGS BELOW 2000
DEVELOPING AFTER 10Z. SURFACE WINDS WILL PROBABLY REMAIN SW 4-8KT
THROUGH 07Z...BUT A SHIFT TO W-NW 4-8 KT IS POSSIBLE ANYTIME THROUGH
07Z. KAM

&&

.MARINE...HIGH PRESSURE OVER THE NORTHEAST PACIFIC AND LOWER

FUCA WITH SCA WINDS IN SPOTS OVER THE N INLAND WATERS AND ADMIRALTY
INLET. THE GALE LOOKS STRONG ENOUGH TO LAST BEYOND 09Z...SO THE
