AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE PORTLAND OR
938 PM PDT FRI AUG 28 2015

UPDATED AVIATION AND MARINE DISCUSSIONS.

.SYNOPSIS...AN USUALLY EARLY AND STRONG LOW PRESSURE WILL PRODUCE
WIDESPREAD RAIN AND STRONG WINDS ACROSS NORTHWEST OREGON AND
SOUTHWEST WASHINGTON SATURDAY MORNING. A FEW THUNDERSTORMS EMBEDDED
IN THE RAIN MAY ENHANCE THE WIND THREAT SATURDAY MORNING. A SECOND
FRONT PUSHING INTO THE REGION FROM THE NORTHWEST SATURDAY NIGHT WILL
PRODUCE ANOTHER ROUND OF RAIN. ADDITIONAL SHOWERS WILL FOLLOW ON
SUNDAY. EXPECT COOL WEATHER AND ADDITIONAL ROUNDS OF SHOWERS FOR MUCH
OF THE UPCOMING WORK WEEK.

&&

.SHORT TERM...VISIBLE AND INFRARED SATELLITE IMAGERY SHOW AN
IMPRESSIVE SURFACE LOW PRESSURE UNDERGOING CYCLOGENESIS OFF THE
SOUTHERN OREGON COAST NEAR 130W. BUOY 46002 SLP CONTINUES TO DROP
BETWEEN 2-3MB/HOUR AND OUTPACE THE GFS AND EC FORECASTS CONSIDERABLY.
THE 00Z NAM SEEMS TO HAVE PICKED UP ON THIS ADDITIONAL DEVELOPMENT
AND IS AT LEAST CLOSER TO REALITY THAN THE 18Z GFS AND 12Z EC RUNS AT
THIS POINT. THE NAM FORECASTS THE LOW TO BOTTOM OUT AROUND 990MB OFF
THE MOUTH OF THE COLUMBIA RIVER AROUND 15Z SATURDAY BEFORE CLIPPING
CAPE FLATTERY ON ITS WAY NORTHWARD. SUSPECT IT WILL DROP SOLIDLY INTO
THE 980S. MEANWHILE...THE EC AND GFS HAVE CONTINUED TO TREND TOWARDS
GRADUALLY SHIFTING THE LOW TRACK SLIGHTLY FARTHER OFFSHORE...WHICH
EVEN WITH THE DEEPER DEVELOPMENT OBSERVED SO FAR...SHOULD HELP TO
KEEP THIS STORM FROM REALIZING ITS FULLEST POTENTIAL IN THE
WILLAMETTE VALLEY AND LOWER COLUMBIA RIVER VALLEY. WITH THAT
SAID...THE RAP BRINGS THE LOW PRESSURE ONSHORE OVER THE OLYMPIC
PENINSULA. THE RAP DID A DECENT JOB DEPICTING THE TRACK OF SEVERAL OF
OUR STRONGER LOW PRESSURES LAST YEAR SO IT IS TOUGH TO DISCOUNT IT
EVEN THOUGH IT IS CONSIDERABLY DIFFERENT THAN THE GLOBAL GFS AND EC
MODEL SOLUTIONS. GIVEN THE UNCERTAINTY IN THE FINAL TRACK OF THIS
LOW...ALL THE INHERITED HEADLINES SEEM REASONABLE AT THIS POINT.
HOWEVER...WILL NUDGE UP THE MENTION OF WIND GUSTS ALONG THE NORTH
OREGON AND SOUTH WASHINGTON COASTS AND ACROSS THE LOWER COLUMBIA
RIVER VALLEY AND PORTLAND METRO AREA WHERE A FEW HIGHER WIND GUSTS
SEEM POSSIBLE...ESPECIALLY IF THE LOW PRESSURE PUSHES ONTO THE
WASHINGTON COAST.

EXPECT THE WINDS TO COME ON RATHER SUDDENLY SATURDAY MORNING. THE
STRONG BURST OF WINDS SHOULD FIRST HIT THE CENTRAL OREGON COAST
BETWEEN 4 AM AND 6 AM...AND THE NORTH OREGON COAST...THE SOUTH
WASHINGTON COAST...AND THE WILLAMETTE VALLEY BETWEEN 7 AM AND 10 AM.
WHILE WINDS WILL STILL BE NOTABLY GUSTY SATURDAY AFTERNOON...THE
STRONGEST WINDS WILL LIKELY ONLY LAST FOR 2 TO 4 HOURS.

IN ADDITION...EXPANDED THE MENTION OF THUNDER TO A LARGER PORTION OF
THE CWA FOR SATURDAY MORNING AS THE NAM CONTINUES TO ADVERTISE
SUFFICIENT INSTABILITY TO PRODUCE A THUNDERSTORM OR TWO ALONG THE
FRONT. GIVEN THE AMPLE SHEAR...ANY STORMS THAT DO DEVELOP WILL NEED
TO BE MONITORED CLOSELY FOR PRODUCING LOCALIZED DAMAGING WINDS.

WHILE MOST EVERYONE SHOULD SEE A QUICK SHOT OF RAIN LATER TONIGHT AND
SATURDAY MORNING...SUSPECT TOMORROW WILL BE MORE DRY THAN WET FOR
MANY. HOWEVER...NOT ALL IS LOST AS MODELS HAVE TRENDED WETTER WITH A
SECOND FRONT DROPPING SOUTHEASTWARD OUT OF THE GULF OF ALASKA THAT
WILL PUSH A HEALTHY DOSE OF RAIN ACROSS THE AREA SATURDAY NIGHT.
DECENT ONSHORE FLOW AND INSTABILITY SHOULD LEAD TO MORE SHOWERS AND
POSSIBLY A WET THUNDERSTORM OR TWO SUNDAY.

BELOW AVERAGE TEMPERATURES AND ADDITIONAL ROUNDS OF WET WEATHER
APPEAR LIKELY NEXT WEEK. /NEUMAN

.LONG TERM...MONDAY NIGHT THROUGH FRIDAY. THE FALL-LIKE WEATHER
PATTERN WILL CONTINUE NEXT WEEK WITH PRIMARILY COOLER THAN NORMAL
TEMPERATURES...CLOUDY CONDITIONS...AND CHANCES FOR ADDITIONAL RAIN. A
TROUGH WILL REMAIN NEAR THE PACIFIC NORTHWEST COAST THROUGH MOST OF
THE PERIOD WITH SOME RAIN AT TIMES...ESPECIALLY DURING THE EARLY AND
MIDDLE PARTS OF NEXT WEEK. LITTLE CHANGE MADE TO THE CURRENT
FORECAST. TOLLESON

&&

.AVIATION...VFR CONDITIONS CONTINUE ACROSS THE REGION WITH LIGHT
DRIZZLE STARTING TO MOVE IN ALONG THE COAST. EXPECT CIGS ALONG THE
COAST TO LOWER TOWARDS MVFR OVER THE NEXT SEVERAL HOURS AS RAIN
CHANCES INCREASE. BRIEF PERIODS OF IFR CIGS AND VSBY WILL BE
POSSIBLE UNDER MODERATE TO HEAVY RAIN. RAIN WILL MOVE INLAND AFTER
09Z AND COULD BRING LOWER CIGS AND VSBY TO THE INTERIOR TAF SITES
THROUGH MUCH OF SATURDAY. SOUTHERLY WINDS ALONG THE COAST WILL
INCREASE AROUND 09Z-12Z ALONG THE CENTRAL OREGON COAST AND 12Z
TO 15Z ALONG THE NORTH OREGON COAST...WITH GUSTS UP TO 35 TO 45
KT. SOUTHERLY WINDS AT INLAND SITES START TO INCREASE AROUND 11 TO
13Z WITH GUSTS TO 25 TO 35 KT AND OCCASIONALLY TO 40 KT.

KPDX AND APPROACHES...VFR THROUGH TONIGHT. RAIN CHANCES INCREASE
AFTER 09Z WITH BRIEF PERIODS OF MVFR CIGS AND VSBY POSSIBLE UNDER
MODERATE TO HEAVY RAIN BANDS. SOUTHERLY WINDS INCREASE AROUND 11Z
WITH GUSTS TO 25 TO 35 KT AND OCCASIONAL GUST TO 40 KT POSSIBLE.
/64/MCCOY

&&

.MARINE...A STRENGTHENING FALL-LIKE LOW PRESSURE SYSTEM WILL MOVE
ACROSS THE WATERS SATURDAY. WINDS WILL INCREASE OUT OF THE SOUTH
TO AT LEAST HIGH-END GALES. MODELS HAVE CONTINUED THE UPWARD
TREND IN THE WINDS...WHICH COULD BRING A FEW HOURS OF ISOLATED
STORM FORCE GUSTS LATE SATURDAY MORNING...BUT CONFIDENCE IN THE
DURATION AND EXTENT OF THE STRONGEST WINDS REMAIN TOO LOW TO
UPGRADE TO A STORM WARNING. SEAS CURRENTLY AROUND 4 FT WILL BUILD
RAPIDLY TO 15 TO 17 FT...AND POSSIBLY AS HIGH AS 20 TO 25 FT...AS
THE WINDS INCREASE EARLY SATURDAY MORNING. SEAS WILL REMAIN
ELEVATED THROUGH LATE SATURDAY. WINDS SHIFT MORE TO THE SOUTH-
SOUTHWEST BY SATURDAY EVENING AND FALL BACK DOWN TO 15 KT GUSTING
TO 20 TO 25 KT BY SUNDAY MORNING. SEAS ON SUNDAY WILL BE AROUND 8
TO 10 FT AS WINDS CONTINUE TO DECREASE TO 10 TO 15 KT BY SUNDAY
EVENING.

UNSETTLED WEATHER CONTINUES INTO NEXT WEEK WITH SEAS STAYING
AROUND 7 TO 9 FT THROUGH AT LEAST MIDWEEK. /64/MCCOY
