AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SEATTLE WA
830 PM PDT WED MAY 2 2012

.SYNOPSIS...A FRONTAL SYSTEM WILL BRING RAIN LATER TONIGHT AND
THURSDAY MORNING...CHANGING TO SHOWERS THURSDAY AFTERNOON. AN UPPER
TROUGH WILL KEEP THE WEATHER COOL AND SHOWERY INTO FRIDAY. HIGH
PRESSURE WILL BRING DRY WEATHER WITH A WARMING TREND THIS WEEKEND
AND EARLY NEXT WEEK.

&&

.SHORT TERM...THERE ARE STILL A FEW SHOWERS FLOATING AROUND NEAR THE
COAST THIS EVENING. THERE WILL BE A VERY BRIEF PERIOD OF DRYING AND
SUBSIDENCE AHEAD OF THE NEXT APPROACHING FRONTAL SYSTEM WHICH WILL
KEEP THIS SHOWER ACTIVITY SUPPRESSED FOR THE NEXT FEW HOURS. RAIN
FROM THIS FRONTAL SYSTEM WILL SPREAD UP FROM THE SOUTHWEST AFTER
MIDNIGHT WITH RAIN AT TIMES CENTRAL COAST AND SOUTHWEST INTERIOR.
THE LIGHT RAIN SHOULD SPREAD AS FAR NORTH AS SEATTLE BY DAYBREAK
WITH RAIN AT TIMES MOST AREAS DURING THE MORNING HOURS...HEAVIER TO
THE SOUTH. THE FRONT WILL SHIFT EAST OF THE CASCADES IN THE
AFTERNOON WITH RAIN CHANGING TO SHOWERS. A CONVERGENCE ZONE IS
LIKELY BEHIND THE FRONT THURSDAY NIGHT. HIGHS THURSDAY WILL BE
SEVERAL DEGREES BELOW NORMAL WITH THE CLOUDS AND RAIN.

AN UPPER TROUGH WILL MOVE OVER THE AREA ON FRIDAY FOR A CONTINUED
CHANCE OF SHOWERS. HIGHS WILL BE ABOUT THE SAME AS THURSDAY...
SEVERAL DEGREES BELOW NORMAL. AN UPPER RIDGE WILL BEGIN BUILDING
OVER THE AREA ON SATURDAY. THIS WILL BRING DRIER AND SLIGHTLY WARMER
WEATHER ALTHOUGH MOIST ONSHORE FLOW WILL KEEP THE THREAT OF A FEW
SHOWERS AND PLENTY OF CLOUDS IN THE FORECAST. SCHNEIDER

.LONG TERM...PREVIOUS DISCUSSION...EXTENDED MODELS IN GOOD AGREEMENT
FOR THE FIRST HALF OF THE EXTENDED WITH AN UPPER LEVEL RIDGE
BUILDING OVER THE PACIFIC NORTHWEST RESULTING IN DRIER AND WARMER
WEATHER. SOME DIFFERENCES START TO APPEAR ON MONDAY WITH THE GFS
BEGINNING TO SHIFT THE UPPER LEVEL RIDGE EAST WHILE THE ECMWF AND
CANADIAN KEEP THE RIDGE IN PLACE OVER WESTERN WASHINGTON. ECMWF IS
THE STRONGEST OF THE MODELS WITH THE RIDGE WITH THE 500 MB HEIGHTS
GETTING INTO THE HIGH 570 DMS BY LATE MONDAY. AT THE SURFACE THE
FLOW NEVER REALLY TURNS OFFSHORE. THIS WILL KEEP HIGHS FROM GETTING
TOO WARM BUT STILL WELL ABOVE NORMAL...UP TO 10 DEGREES...HIGH
TEMPERATURES EXPECTED MONDAY. WITH THE FASTER SHIFT EAST IN THE
UPPER LEVEL RIDGE MONDAY RESULTS IN A MUCH STRONGER MARINE PUSH ON
TUESDAY FOR THE GFS SOLUTION. THE ECMWF AND CANADIAN HAVE JUST A
WEAK PUSH ON TUESDAY. THE ENSEMBLES ARE NOT MUCH HELP WITH BOTH THE
ECMWF AND GFS ENSEMBLES SHOWING A LOT OF VARIATION IN THE SOLUTIONS.
FOR NOW WILL LEAN TOWARD THE ECMWF AND ONLY COOL TEMPS A COUPLE OF
DEGREES ON TUESDAY FOR THE INTERIOR. MORE DIFFERENCES IN THE MODEL
ON WEDNESDAY WITH THE GFS PUTTING A TROUGH OVER THE AREA WHILE THE
ECMWF HAS JUST WESTERLY FLOW ALOFT AND NORTHWESTERLY SURFACE
GRADIENTS WITH A STRONG SURFACE HIGH OFF THE COAST. WILL STAY WITH
THE DRY ECMWF SOLUTION BUT CONTINUE THE TREND OF COOLER MAX TEMPS.
FELTON

.AVIATION...SW FLOW ALOFT. THE AIR MASS IS STABLE WITH MID AND HIGH
LEVEL MOISTURE GRADUALLY INCREASING AND LOWERING AS THE RAIN SHIELD
ASSOCIATED WITH A 999 MB LOW THAT IS MOVING ONTO THE CENTRAL OREGON
COAST LIFTS NORTH INTO WESTERN WASHINGTON. LIGHT RAIN MOVING INTO
KHQM AT 03Z WILL LIFT NE TO THE KSEA AREA 10Z-12Z THEN WILL MOVE N
TO THE CANADIAN BORDER BY 15Z. LIGHT N TO NE GRADIENTS TO THE N OF
THE INCOMING LOW WILL INITIALLY KEEP CEILINGS 035-050 TONIGHT...BUT
BY ABOUT 12Z EXPECT CIGS TO DROP TO 015-025 IN THE LIGHT
PRECIPITATION. CIGS MAY DROP TO 010-015 S OF KTCM IN THE INTERIOR
12Z-20Z. CONDITIONS WILL GRADUALLY IMPROVE TO BKN030-040 AFTER 20Z
AS ONSHORE FLOW GRADUALLY INCREASES WITH THE WEAKENING LOW LIFTING
NE THROUGH EASTERN WASHINGTON. HOWEVER...CEILINGS MAY REMAIN MVFR IN
THE CENTRAL PUGET SOUND AREA WITH A PUGET SOUND CONVERGENCE ZONE.

KSEA...LIGHT SLY WIND WILL SWITCH TO LIGHT NORTHEASTERLY AFTER 06Z.
CEILINGS 150 WILL LOWER TO 050 AROUND 06Z THEN FALL TO 020-025
12Z-20Z WITH -RA. FLOW WILL BECOME VARIABLE 5-8 KT 20Z ONWARD AS A
PUGET SOUND CONVERGENCE ZONE DEVELOPS NEAR THE TERMINAL. ALBRECHT

&&

.MARINE...A WEAK RIDGE OF HIGH PRES OVER THE INLAND WATERS WILL
SHIFT EAST OF THE CASCADES THIS EVENING. IN THE MEANTIME...A 999 MB
LOW NEAR 44N 131W WILL MOVE ONTO THE CENTRAL OREGON COAST EARLY
THURSDAY MORNING THEN WILL WEAKEN AS IT LIFTS NE THROUGH EASTERN
WASHINGTON THURSDAY AFTERNOON AND INTO SE BRITISH COLUMBIA THURSDAY
EVENING.

A RIDGE OF HIGH PRES WELL OFFSHORE WILL BUILD EAST TOWARD
THE OFFSHORE WATERS THURSDAY EVENING THEN WILL BUILD OVER THE
OFFSHORE AND COASTAL WATERS FRI AND FRI NIGHT. THE COMBINATION OF
LOWER PRESSURES E OF THE CASCADES THU EVENING AND BUILDING HIGH PRES
OFFSHORE WILL INCREASE ONSHORE PRES GRADIENTS WITH SMALL CRAFT
ADVISORY NW WINDS DEVELOPING OVER THE COASTAL WATERS LATE THU
AFTERNOON AND THROUGH THE STRAIT OF JUAN DE FUCA DURING THE EARLY
EVENING HOURS.

MODERATE ONSHORE FLOW WILL CONTINUE FRI THROUGH FRI EVENING. A WEAK
FRONTAL SYSTEM WILL MOVE THROUGH THE WATERS LATE FRI NIGHT INTO SAT
