AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PORTLAND OR
225 PM PDT MON SEP  1 2014

.SYNOPSIS...A WEAKENING FRONT WILL KEEP SOME CLOUDS ALONG THE NORTH 
COAST THIS EVENING...OTHERWISE IT WILL BE MOSTLY CLEAR.  AN UPPER 
LEVEL TROUGH WILL MOVE ACROSS THE REGION TUESDAY INTO EARLY 
WEDNESDAY BRINING COOLER AND CLOUDY WEATHER. THIS SYSTEM WILL ALSO 
BRING SOME LIGHT RAIN TO SOUTHWEST WASHINGTON AND THE FAR NORTHERN 
PART OF NORTHWEST OREGON TUESDAY AFTERNOON AND TUESDAY NIGHT. AN 
UPPER LEVEL RIDGE COMBINED WITH LOW-LEVEL EASTERLY WINDS WILL RESULT 
IN SUNNIER AND WARMER WEATHER FOR THE LATTER PART OF THE WEEK. 
ONSHORE FLOW WILL RETURN NEXT SUNDAY. 
 
&&

.SHORT TERM...TONIGHT THROUGH THURSDAY...A WEAKENING FRONT JUST OFF
THE WA/OR COAST THIS AFTERNOON KEEPING A PERSISTENT AREA OF CLOUDS
OVER THE NORTH COASTAL AREA...MAINLY FROM ABOUT TILLAMOOK NORTHWARD 
THIS AFTERNOON. WEBCAM IMAGERY AT ASTORIA THIS AFTERNOON ALSO SHOWED 
SOME SPOTTY LIGHT DRIZZLE OCCURRING FROM TIME TO TIME. ELSEWHERE... 
LOTS OF SUNSHINE GIVING WAY TO A SPLENDID LABOR DAY. 

AN UPPER LEVEL TROUGH OFF THE BRITISH COLUMBIA COAST WILL DROP SOUTH 
TOWARDS THE PACIFIC NW LATER TONIGHT. THE MARINE LAYER SHOULD DEEPEN 
TONIGHT AND WITH INCREASED ONSHORE FLOW TONIGHT. THUS...EXPECT 
MARINE CLOUDS TO PUSH FARTHER INLAND TUESDAY MORNING.  A WEAK FRONT 
ASSOCIATED WITH THE UPPER LEVEL TROUGH WILL MOVE ACROSS THE NORTHERN 
PART OF THE REGION TUESDAY AFTERNOON/EVENING.  THE FRONT WILL 
PRODUCE SOME LIGHT RAIN ALONG THE NORTH COAST/COAST RANGE AND PART 
OF THE INLAND AREA. BEST CHANCES OF MEASURABLE RAIN WILL BE IN 
SOUTHWEST WA...BUT THE NORTHERN WILLAMETTE VALLEY AND ADJACENT 
FOOTHILLS AND NORTH CASCADES WILL BE ON THE SOUTHERN END OF THE 
FRONT AND COULD GET ALITTLE RAIN TUES EVE/NIGHT.  THERE WILL BE 
ANOTHER DEEP MARINE PUSH TUESDAY NIGHT WITH A CLOUDY START TO THE 
DAY ON WEDNESDAY. THE UPPER TROUGH AND INCREASE IN CLOUDS WILL KEEP 
THE TEMPERATURES BELOW NORMAL TUESDAY AND WEDNESDAY. 
 
HIGH PRESSURE WILL REBUILD OVER THE REGION THURSDAY. A FAIRLY STRONG 
THERMAL TROUGH WILL ALSO BUILD NORTHWARD ALONG THE COAST. THIS WILL 
RESULT IN OFFSHORE FLOW...CLEAR SKIES...AND WARMER TEMPERATURES 
THE LATTER PART OF THE WORK WEEK. TW

.LONG TERM...FRIDAY THROUGH MONDAY...A WEAK...POSITIVELY-TILTED 
TROUGH WILL MOVE THROUGH OUR AREA LATE THIS WEEK.  NOT ONLY IS 
MOISTURE LIMITED FOR THE PASSAGE OF THIS SYSTEM...BUT ANY 
PRECIPITATION THAT DOES DEVELOP SHOULD BE EAST OF THE CASCADE 
RIDGE...OUTSIDE OF OUR AREA.  LATE THIS WEEKEND THE 
GFS...ECMWF...AND DGEX ALL ARE SUGGESTING A LONGWAVE TROUGH WILL 
MOVE ONSHORE BRINGING A CHANCE FOR SOME RAINFALL SUNDAY NIGHT OR 
MONDAY. DISAGREEMENT BETWEEN MODELS ON TIMING AND BECAUSE OF HOW FAR 
OUT THIS SYSTEM IS IN THE FORECAST PERIOD...THERE IS A LOT OF 
UNCERTAINTY WITH THIS SYSTEM. KEPT POPS THE SAME AS THEY CAPTURE 
THIS UNCERTAINTY WELL. -MCCOY
&&

.AVIATION...A WEAK DISTURBANCE WILL BE PASSING BY THROUGH WESTERN
WASHINGTON AND BRUSH EXTREME NORTHWEST OREGON TODAY FOR SOME FOR
MOSTLY VFR CIGS ALONG THE SOUTH WASHINGTON AND NORTH OREGON COASTS
AND INLAND NEAR THE COLUMBIA RIVER TO KKLS OR SO. THE LOWEST CIGS
WILL BE ALONG THE NORTH COASTAL AREAS. FARTHER INLAND THERE MAY BE
A FEW CIGS NEAR THE MOUNTAINS BUT LESS CHANCE IN THE VALLEYS. THE
SURFACE PATTERN SUGGESTS THE CENTRAL OREGON COAST AND THE SOUTH
WILLAMETTE VALLEY WILL TEND TO STAY CLEAR THIS AFTERNOON AND
EVENING. WITH PLENTY OF CLOUDS UPSTREAM OVER THE NE PACIFIC...
EXPECT MVFR CIGS TO PUSH ONTO THE COAST OVERNIGHT TONIGHT AND
SPREAD INLAND TO KPDX AND POSSIBLY A BIT SOUTH BY TUESDAY MORNING.
ANOTHER MORE ORGANIZED FRONT IS EXPECTED TO SPREAD IN FROM THE
NORTHWEST TUESDAY WITH MVFR CIGS OR PERHAPS HIGH IFR AND SOME
LIGHT RAIN ON THE COAST...APPROACHING KPDX BY 00Z WEDNESDAY...
WHICH IS 5 PM TUESDAY.

KPDX AND APPROACHES...VFR CONDITIONS TODAY. MAY SEE SOME VFR CIGS
FOR A TIME LATE THIS AFTERNOON AND EVENING AROUND 5000 OR 6000

TERMINAL TOWARDS 12Z TUESDAY. SOME VFR CIGS AND POSSIBLY A SHOWER
ARE POSSIBLE LATE TUESDAY. PT

.MARINE...A WEAK DISTURBANCE PASSING BY TO OUR NORTH BRIEFLY
TURNED THE WINDS IN OUR NORTHERN WATERS TO LIGHT SOUTHERLY...BUT
THEN WEAK HIGH PRES WILL BRIEFLY BUILD BACK IN TONIGHT AND EARLY
TUESDAY FOR NORTH TO NORTHWEST FLOW ALONG THE ENTIRE COAST...WHICH
MAY GIVE SMALL CRAFT ADVISORY THRESHOLD GUSTS TO OUR CENTRAL
OREGON WATERS MAINLY TONIGHT. ANOTHER SLIGHTLY STRONGER FRONTAL
BAND IS FORECAST TO MOVE INTO THE WATERS MIDDAY TUESDAY AND
ONSHORE TUESDAY EVENING...WITH THE MAIN EFFECT BEING SOME
MODERATE NW WINDS BEHIND THE FRONT THAT MAY GIVE SOME GUSTS ABOVE
20 KT AS WELL ESPECIALLY IN THE OUTER WATERS. THE THERMAL TROUGH
BEGINS REDEVELOPING IN NORTHERN CALIFORNIA WEDNESDAY...WITH SMALL
CRAFT ADVISORY THRESHOLD NORTHERLY WINDS BEGINNING TO SPREAD NORTH
ALONG THE CENTRAL OREGON COAST LATE WEDNESDAY. THE WINDS WILL THEN
SPREAD NORTHWARD THROUGH ALL THE WATERS THURSDAY AND FRIDAY AS
THE THERMAL TROUGH CONTINUES TO BUILDS FARTHER NORTH ALONG THE
COAST. WINDS THURSDAY AFTERNOON AND EVENING WILL BE ON THE HIGH
SIDE OF THE SMALL CRAFT ADVISORY RANGE.

SEAS MAY GET CLOSE TO 10 FT IN THE NORTHERN WATERS FROM THE
NORTHWESTERLIES WEDNESDAY...AND POSSIBLY AGAIN AROUND 8 TO 10 FT
