High Wind in Oregon, January 18, 2012

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PORTLAND OR
1046 PM PST TUE JAN 17 2012

.SYNOPSIS...A STRONG SURFACE LOW WILL MOVE TO NEAR ASTORIA BY
WEDNESDAY AFTERNOON BEFORE WEAKENING AND DRIFTING NORTH. THIS WILL
BRING VERY STRONG GUST WINDS TO THE COAST...THE CASCADES AND TO A
SMALLER EXTENT THE WILLAMETTE VALLEY LATE TONIGHT AND WEDNESDAY.
SEVERAL MORE STORM SYSTEMS WILL BATTER THE FORECAST AREA THURSDAY
THROUGH EARLY NEXT WEEK.

&&

...URGENT NOTICE OF UPDATE...

THIS IS JUST A VERY QUICK UPDATE TO LET EVERYONE KNOW WE ARE IN THE
PROCESS OF UPGRADING TO A WINTER STORM WARNING FOR THE PORTLAND AND
VANCOUVER METRO AREA...AND OUR LOWLANDS TO THE NORTH. THE WARNING
WILL BE ISSUED SHORTLY...AND THE APPROPRIATE ADJUSTMENTS WILL BE
MADE FOR THE FORECASTS.

SNOW HAS ALREADY ACCUMULATED UP TO AROUND AN INCH HERE AT THE OFFICE
IN NE PORTLAND AND LOCALLY UP TO 3 INCHES IN PARTS OF GRESHAM...
SEVERAL INCHES MORE ARE EXPECTED BEFORE CHANGEOVER TO RAIN OCCURS
WEDNESDAY MORNING. MUCH LESSER ACCUMULATIONS THUS FAR ON THE WEST
SIDE...BUT THEY ARE LIKELY TO START ACCUMULATING SOON.  THIS IS
SHAPING UP TO BE A WIDESPREAD SIGNIFICANT WINTER WEATHER EVENT FOR
THE PORTLAND AND VANCOUVER METRO AREA.

.SHORT TERM...STILL QUITE A BIT OF UNCERTAINTY AS TO THE EXTENT OF
FINER DETAILS REGARDING THE POTENTIAL SNOW EVENT LATE TONIGHT.
STATING THE OBVIOUS...SNOWFALL TONIGHT WILL BE HIGHLY DEPENDENT ON
ELEVATION AND HOW FAR NORTH ONE GETS. A MAJOR DRAWBACK PREVENTING
THIS FROM BEING A WIDESPREAD MAJOR SNOW EVENT IS THE LACK OF A COLD
AIR SOURCE. GRANTED...COLD AIR HAS WORKED ITS WAY INTO NORTHERN AND
CENTRAL WASHINGTON...BUT IT IS HAVING A HARD TIME MIGRATING SOUTH.
03Z TEMPS IN THE COLUMBIA BASIN WERE IN THE 30S...WHICH IS CERTAINLY
NOT FAVORABLE FOR DRAWING THE NEEDED COLD AIR THROUGH THE GORGE INTO
THE PORTLAND/VANCOUVER METRO AREA.

THE 00Z KSLE SOUNDING SHOWED ABOUT -4C AT 850 MB...WHICH WAS CLOSER
TO THE GFS FORECAST THAN THE NAM. ACTUALLY...THE GFS WAS A TOUCH TOO
WARM AND THE NAM A TAD COOL. RAPID UPDATE CYCLE (RUC) SOUNDING VIA
BUFKIT FOR KPDX INDICATES SNOW FROM ABOUT 07Z-16Z. THE RUC SOUNDING
FOR KSLE SHOWS ALL RAIN...WITH SNOW DOWN TO ABOUT 500 FEET. THUS...AS
HAS BEEN SAID THE PAST COUPLE OF DAYS...THERE IS A FINE LINE BETWEEN
THOSE THAT GET SOME SNOW AND THOSE THAT DO NOT. LOOK FOR OFFSHORE
LOW-LEVEL FLOW TO DEVELOP IN THE GORGE AROUND MIDNIGHT AND GET A
LITTLE STRONGER THROUGH THE LATE-NIGHT HOURS. NAM HAS THE SURFACE LOW
HEADED TOWARD ABOUT KTMK AT 15Z...BUT IT ENDS UP AT KAST
18Z-21Z...SIMILAR TO PAST COUPLE RUNS. STILL THINK THE OFFSHORE FLOW
WILL PULL JUST ENOUGH COLD AIR TO GIVE A PERIOD OF SNOW TO THE METRO
AREA...ESPECIALLY ABOVE 500 FEET. THE 12KM MM5-NAM SHOWS ABOUT 1 TO 4
INCHES FOR KPDX BETWEEN 09Z AND 15Z...THEN EVERYTHING TURNS TO RAIN.
THE SAME MODEL SHOWS 1-2 INCH/HR...LOCALLY UP TO 3 IN/HR...SNOWFALL
RATES IN THE CASCADES. THE SKI AREAS HAVE ALREADY PICKED UP AROUND 2
FEET SINCE MON AFTERNOON (SEE PNS AND LSR).  POINTS SOUTH OF SALEM
WILL LIKELY SEE LITTLE TO NO SNOW. THE CENTRAL AND SOUTH WILLAMETTE
VALLEY ABOVE 500 TO 1000 FEET WILL GET SOME OVERNIGHT...BUT IT WILL
NOT LAST LONG.

LATEST AVAILABLE MODELS MAINTAIN AN ABRUPT SHIFT TO STRONG SOUTH
LOW-LEVEL FLOW WED. THE CURRENT WIND WARNINGS REMAIN ON TRACK.
INTERESTING TO NOTE THAT THE RUC SOUNDING FOR KSLE VALID 17Z HAS SW
WIND OF 50 KTS AT 2100 FT...AND UP TO 80 KT AT 5000 FT. WOULD NOT BE
SURPRISED TO SEE 100 MPH AT THE 7000 FT TIMBERLINE LODGE SENSOR.
ELSEWHERE...SOUTH WIND WILL BEGIN TO STRENGTHEN ALONG THE CENTRAL
COAST AROUND MIDNIGHT...THEN SPREAD NORTH OVERNIGHT AND EARLY WED
MORNING. STILL LOOKS LIKE HIGH-END WIND ADVISORY CONDITIONS FOR THE
WILLAMETTE VALLEY WED...ESPECIALLY SOUTH OF SALEM. THE LATEST MET
GUIDANCE SHOWS SUSTAINED WIND OF 28 KT FOR KSLE AT 18Z.

ANOTHER CONCERN WILL BE THE QPF. AMSU TOTAL PRECIPITABLE WATER VALUES
WERE AROUND 2.0 INCHES OUT AT 40N/144W. LATEST GFS HAS 6-HR RAINFALL
UP TO AN INCH ALONG THE COAST 06Z-12Z WED AND UP TO 2 INCHES 12Z-18Z.
COMBINE THAT WITH 60-75 KT 850 MB SWLY FLOW...THE OROGRAPHIC
COMPONENT SHOULD BE TREMENDOUS. BY 00Z THU THE CASCADE SNOW LEVELS
WILL BE UP ABOVE 3500 FEET...EXCEPT FOR THE S WA CASCADES AND EXTREME
N OREGON CASCADES CLOSEST TO THE GORGE. BY 06Z THU SNOW LEVELS GO UP
TO 4000 FEET NEAR MT. HOOD TO OVER 7000 FEET IN THE LANE COUNTY
CASCADES. THE NAM SHOWS ANOTHER SYSTEM DEVELOPING ALONG THE LEFT-OVER
BAROCLINIC ZONE OVER SWRN OREGON AND NRN CA THU WILL IMPACT THE
FORECAST AREA THU. WEISHAAR

.LONG TERM...NO CHANGES. PREVIOUS DISCUSSION FOLLOWS...SEVERAL
SIGNIFICANT STORMS WILL TRACK OVER THE PACIFIC NORTHWEST THROUGH MUCH
FOR THE EXTENDED PERIOD. SNOW LEVELS REMAIN WELL ABOVE 3000 FEET WITH
THE SYSTEM THE MOVES THROUGH LATE FRIDAY...MAINTAINING HEAVY RAIN
ACROSS THE FORECAST AREA INTO SATURDAY. THE NEXT SYSTEM APPROACHES
LATE SATURDAY... BRINGING A THREAT FOR STRONG WINDS ALONG THE COAST
SATURDAY NIGHT INTO SUNDAY. SNOW LEVELS ARE EXPECTED TO DROP WITH
THIS SYSTEM...SO AREAS ABOVE ABOUT 1500 TO 2000 FEET CAN EXPECT SNOW
THROUGH SUNDAY. MODERATE PRECIPITATION CONTINUES INTO EARLY NEXT WEEK
UNDER A WESTERLY FLOW PATTERN...WITH ANOTHER POSSIBLY STRONG SYSTEM
BY MONDAY NIGHT. WILL CONTINUE TO MAINTAIN ABUNDANT PRECIPITATION
AMOUNTS AND COOLER TEMPERATURES THROUGH NEXT WEEKEND.

WILL BE KEEPING A CLOSE EYE ON ANY HYDRO ISSUES THAT WILL LIKELY
APPEAR BY THURSDAY AND FRIDAY AS RISING RIVER LEVELS ARE A CONCERN.
BROWN

&&

.AVIATION...STEADY LIGHT TO MODERATE RAIN WILL CONTINUE THIS EVENING
WITH WIDESPREAD MVFR CONDITIONS AND TRENDING TO IFR AS
PRECIPITATION PICKS UP LATER TONIGHT. LOCATIONS NORTH AND WEST OF
KPDX WILL SEE SNOW MIXED IN...AS WELL AS IN THE COLUMBIA RIVER
GORGE. BUT SOUTHERLY WINDS HAVE NOW EASED AROUND PORTLAND AND
TROUTDALE...AND NOW WE ARE SEEING SNOW AT KTTD AND RAIN/SNOW AT
KPDX. FEEL PRETTY CONFIDENT THAT VALLEY LOCATIONS SOUTH OF AURORA OR
SO WILL REMAIN ALL RAIN TONIGHT. THE POTENTIAL FOR SNOW ARE THE VERY
STRONG WINDS EXPECTED AT THE COAST AND POTENTIALLY INLAND AS
WELL...THOUGH THE INLAND WINDS ARE LESS CERTAIN AT THIS TIME.

PRECIPITATION TRANSITIONS TO ALL MODERATE TO HEAVY RAIN DURING THE
DAY BEFORE EASING TOMORROW NIGHT...AND EXPECT ALL LOCATIONS EXCEPT
THE GORGE TO BE RAIN BY MIDDAY. EXPECT A MIX OF MVFR AND MORE LIKELY
IFR TO CONTINUE. OF ADDITIONAL CONCERN ARE THE STRONG SOUTHERLY
WINDS TOMORROW THAT WILL BE FOUND NOT ONLY AT THE COAST...BUT EXPECT
BREEZY TO WINDY CONDITIONS IN THE VALLEY...WITH THE STRONGEST VALLEY
WINDS FROM SALEM SOUTH.

KPDX AND APPROACHES...EXPECT A RAIN/SNOW MIX TO CONTINUE THIS
EVENING...AND THEREFORE VARYING CONDITIONS FROM MVFR TO
IFR...BEFORE HEAVY PRECIPITATION ARRIVES OVERNIGHT WITH
PREDOMINANT IFR REGARDLESS OF PRECIP TYPE. IT IS POSSIBLE TO SEE
ACCUMULATING SNOW AT THE TERMINAL MAINLY OVERNIGHT. LIKE MOST
STORMS IT WILL BE SPLITTING HAIRS TO DETERMINE IF IT WILL STICK AT
KPDX OR NOT. LATEST GUIDANCE HAS NOT CHANGED MUCH...BUT WE WILL
CONTINUE TO WATCH AS TROUTDALE IS NOW SEEING ALL SNOW AND FALLING
TEMPERATURES. IF COLD AIR LINGERS LONG ENOUGH THE WORST CASE
SCENARIO WOULD BE 4 PLUS INCHES WHILE MOST GUIDANCE POINTS TO 1 TO
3 INCHES OF VERY WET SLUSHY ACCUMULATION IF ANY BEFORE A CHANGE OVER
TO RAIN. THAT SAID...MOST GUIDANCE IS TOO WARM ON SFC TEMPS AND
DEWPOINTS AT THE MOMENT...AND HAVE INCREASED CONCERNS ON STICKING
SNOW...GIVEN HEAVIER PRECIP RATES OVERNIGHT. SNOW WILL BE FALLING
HARD AT ELEVATIONS ABOVE 500 FT.

CONFIDENCE LOW ON SPECIFIC SOUTHERLY WINDS TOMORROW...BUT EXPECT
BREEZY CROSS RUNWAY WINDS. KMD/WOLFE

&&

.MARINE...AFTER A RELATIVE LULL IN COASTAL WATERS WINDS THIS
EVENING...EXPECT
WINDS AND SEAS TO RAPIDLY INCREASE LATE TONIGHT AND TOMORROW NAM
AND GFS BOUNDARY LAYER WIND SPEED BOTH REACH 60-70 KT FOR A SHORT
TIME IN THE MORNING...AND WITH 925-850 MB WINDS IN THE 80+ KNOT
RANGE. SOLID STORM FORCE WINDS WITH A PERIOD OF HURRICANE FORCE
WINDS STILL ON TRACK.

STARTING WEDNESDAY MORNING MORNING A VERY STRONG SYSTEM ARRIVES AND
BRINGS WIND GUSTS IN EXCESS OF 65 KTS TO A GOOD PORTION OF THE
CENTRAL OREGON COASTAL WATERS...SO HAVE ISSUED A HURRICANE FORCE
WIND WARNING FROM 4 AM UNTIL 1 PM PST FOR THE CENTRAL COASTAL
WATERS. THE CENTER OF LOW PRES LOOKS TO PASS RIGHT OVER ASTORIA.
THEREFORE THE NORTHERN WATERS LOOK TO ESCAPE THE STRONGEST WINDS
BUT WINDS WILL LIKELY BE IN THE STRONG STORM FORCE GUST ARENA
DUE TO THE LOW PLACEMENT...THERE MAY BE AREAS WHERE WINDS QUICKLY
SWITCH FROM STRONG OFFSHORE TO VERY STRONG SOUTHWEST. THIS IS AN
EXTREMELY DANGEROUS STORM. PLEASE TAKE NECESSARY PRECAUTIONS!

WILL MAINTAIN A HIGH SURF ADVISORY FOR THE CENTRAL OREGON COAST
WEDNESDAY AND THE COASTAL FLOOD ADVISORY FOR TIDAL OVERFLOW FOR
BOTH THE NORTH AND CENTRAL OREGON COAST. HIGH TIDE IN THE EARLY
MORNING AND STRONG TIDAL ANOMALY EXPECTED GIVEN THE STORM
STRENGTH. S/SW FACING LOCALES WILL EXPERIENCE THE ROUGHEST SURF
CONDITIONS. CONFIDENCE IS LOWER FOR THE NORTH OREGON COAST WITH
LOWER FORECAST SEAS WITH SHORT LOW PERIODS...BUT AGAIN NOT OUT OF
THE QUESTION EITHER AS WE GET CLOSER TO THE EVENT AND SEE HOW
QUICKLY SEAS BUILD.  KMD/WOLFE
