AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PORTLAND OR
921 AM PDT WED SEP 10 2014

.SYNOPSIS...ONSHORE FLOW WILL WEAKEN AND TURN TO A MORE NORTHERLY
DRYING FLOW THIS AFTERNOON. THE LOW LEVEL FLOW WILL TURN MORE
STRONGLY OFFSHORE LATER TONIGHT AND ESPECIALLY THURSDAY AND FRIDAY AS
A THERMAL TROUGH BUILDS UP THE COAST IN THE WAKE OF A COOL EARLY FALL
SYSTEM MOVING THROUGH THE NORTHERN ROCKY MOUNTAIN REGION. THE
OFFSHORE FLOW WILL BE STRONG AND WIDESPREAD ACROSS SOUTHWEST
WASHINGTON AND NORTHWEST OREGON FOR EARLY SEPTEMBER...CONTINUING INTO
FRIDAY. THE DRIER AIR MASS WILL LEAD TO COOLER NIGHTTIME TEMPERATURES
THE NEXT FEW DAYS...ESPECIALLY IN WIND SHELTERED AREAS. THE OFFSHORE
FLOW WILL CONTINUE THIS WEEKEND BUT BE WEAKER... ALLOWING
TEMPERATURES TO REACH CLOSE TO 90 DEGREES IN INLAND AREAS. A RETURN
TO ONSHORE FLOW AND COOLER WEATHER WILL LIKE WAIT UNTIL SOMETIME NEXT
WEEK.
&&

.SHORT TERM...LOW CLOUDS IN THE REMAINING ONSHORE FLOW WERE SOLID
ALONG THE NORTH COASTAL FORECAST ZONES AND INLAND ALONG THE COLUMBIA
RIVER INTO NORTH AND EVEN CENTRAL WILLAMETTE ALONG THE CASCADE
FOOTHILLS. THE CLOUDS WILL CLEAR BACK TO THE COAST BY FAIRLY EARLY IN
THE AFTERNOON...AND CLEAR ALONG THE COAST IN THE REMAINDER OF THE
AFTERNOON AS THE LOW LEVEL ONSHORE NORTHWEST FLOW TURNS MORE
NORTHERLY.

THE MODELS THEN CONTINUE TO ADVERTISE A SIGNIFICANT EARLY SEPTEMBER
WIDESPREAD OFFSHORE WIND EVENT BEGINNING LATE TONIGHT OVER THE HIGHER
TERRAIN AND NEAR THE COAST SPREADING TO THE REMAINDER OF THE LOWLANDS
THURSDAY MORNING. THIS EVENT IS BEING DRIVEN BY THE COLDER AIR BEHIND
THE SYSTEM MOVING THROUGH THE NORTHERN ROCKIES TODAY...INDUCING
A SURFACE THERMAL TROUGH BUILDING UP THE COAST TONIGHT...CONTINUING
ALONG THE COAST THURSDAY THROUGH MOST OF FRIDAY. UNLIKE THE RECENT
EAST WIND EVENT LAST WEEK...THIS EVENT HAS MUCH GREATER THERMAL
FORCING...AND WILL LIKELY RESULT IN STRONG WINDS ACROSS THE MOUNTAINS
AND THROUGH THE GORGE...ALONG THE COAST...AND DOWN THE VALLEYS. THE
STRONGEST WINDS WILL BE ACROSS THE MOUNTAIN RIDGES...NEAR THE EAST
END OF THE GORGE AND THE ADJACENT FOOTHILLS AND EAST
PORTLAND/VANCOUVER METRO AREAS...AND UP IN THE WEST HILLS OF
PORTLAND. GRADIENTS THROUGH THE GORGE COULD REACH 7 TO 8 MB. GUSTS IN
THE GORGE COULD REACH 50 TO 60 MPH...AND IN PARTS OF THE
PORTLAND/VANCOUVER METRO AREA UP AROUND 40 MPH. WITH PLENTY OF LEAVES
ON THE TREES...THIS COULD LEAD TO SOME PROBLEMS IN THE
PORTLAND/VANCOUVER METRO AREAS.

THE WIND EVENT WILL CONTINUE THROUGH THURSDAY NIGHT INTO FRIDAY... AS
THE THERMAL TROUGH AND GRADIENT REMAIN STRONG. THE GRADIENT WEAKENS
LATE FRIDAY...BUT WINDS WILL LIKELY CONTINUE FAIRLY STRONG UNTIL LATE
IN THE DAY. TOLLESON

.LONG TERM...OFFSHORE FLOW CONTINUES INTO THE WEEKEND AS THE THERMAL
TROUGH REMAINS NEAR THE COAST...BUT WILL BE WEAKER. ANY SOUTHERLY
FLOW REVERSAL AND BUILDING OF THE MARINE LAYER ALONG THE COAST MAY
WAIT UNTIL SUNDAY NIGHT OR MONDAY. THE TIMING AND TRACK OF AN UPPER
LEVEL TROUGH IS NOT CONSISTENT ON THE VARIOUS MODELS. AT SOME POINT
EARLY NEXT WEEK WE SHOULD START TO SEE SOME MODERATION. THE MODELS
ARE SHOWING A FRONT COMING IN AROUND WEDNESDAY OF NEXT WEEK. TOLLESON
&&

.AVIATION...MOIST LOW LEVEL NORTHWESTERLY FLOW WILL TRANSITION TO A
MUCH DRIER NORTHEASTERLY FLOW PATTERN OVER THE NEXT 24 HOURS. THIS
WILL ALLOW MVFR CONDITIONS ALONG THE COAST AND LOWER COLUMBIA AND
WILLAMETTE RIVER VALLEYS TO GIVE WAY TO VFR CONDITIONS BETWEEN 18Z
AND 20Z TODAY. STRENGTHENING EASTERLY WINDS AND DRIER AIR OVERNIGHT
SHOULD GENERALLY KEEP ALL TAF SITES VFR THROUGH 18Z THURSDAY. EAST
WIND GUSTS OF 30 TO 40 KT WILL BE POSSIBLE AT KTTD THURSDAY.

KPDX AND APPROACHES...MVFR CONDITIONS SHOULD GIVE WAY TO VFR
CONDITIONS AROUND 19Z TODAY. EAST WINDS SHOULD KICK IN ABRUPTLY
BETWEEN 12Z AND 15Z THURSDAY. EXPECT EASTERLY WIND GUSTS OF 25 TO 35
KT TOWARDS MIDDAY THURSDAY. /NEUMAN
&&

.MARINE...THERMAL LOW PRESSURE WILL BUILD UP THE COAST TONIGHT INTO
THURSDAY. THIS SHOULD BRING GUSTY NORTH TO NORTHEAST WINDS OVER THE
WATERS THROUGH FRIDAY MORNING. THESE GUSTIER WINDS WILL LIKELY BEGIN
THIS AFTERNOON ACROSS THE CENTRAL OREGON WATERS...BUT LIKELY HOLD OFF
UNTIL AFTER MIDNIGHT ACROSS THE NORTHERN WATERS.

GIVEN THE FORECAST WIND SPEEDS THURSDAY...IT SEEMS STEEP SQUARE SEAS
OF APPROXIMATELY 7 TO 8 FT AT 6 OR 7 SECONDS WILL DEVELOP ACROSS THE
FAR OUTER WATERS. WILL CONSIDER ISSUING A SMALL CRAFT FOR HAZARDOUS
SEAS FOR THE OUTER WATERS WITH THE AFTERNOON FORECAST PACKAGE FOR
THURSDAY AFTERNOON AND EVENING AS A RESULT.

STRENGTHENING HIGH PRESSURE OVER THE NORTHEAST PACIFIC SHOULD RESULT
IN WINDS AND SEAS EASING CONSIDERABLY OVER THE WEEKEND...POSSIBLY
LASTING WELL INTO NEXT WEEK. /NEUMAN
