High pressure across Eastern Oregon and Eastern Washington produced strong East winds through the West end of the Columbia River Gorge.
Deaths and injuries are direct and indirect together, as the offices filed them. Damage is property and crops in the dollars of the year, not adjusted for inflation, and only where an office estimated it.
The episode as NWS PQR wrote it up.
High pressure across Eastern Oregon and Eastern Washington produced strong East winds through the West end of the Columbia River Gorge.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Portland, OR wrote its last area forecast discussion before the first event at Nov 28, 9:23 AM PST, 2 hours 2 minutes earlier.
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PORTLAND OR
923 AM PST WED NOV 28 2012
.SYNOPSIS...A LARGE LOW PRESSURE SYSTEM WILL PERSIST OVER THE
NORTHEAST PACIFIC INTO THE WEEKEND. THE FIRST FRONT ASSOCIATED WITH
THIS LOW WILL LIFT NORTH ACROSS THE AREA TODAY. A SECOND STRONGER
MORE ORGANIZED FRONT IS EXPECTED LATER TONIGHT AND THURSDAY. THAT
SYSTEM WILL BRING A THREAT OF HIGH WIND TO THE CENTRAL OREGON COASTAL
HEADLANDS. THE OFFSHORE LOW WILL CONTINUE TO PUSH SYSTEMS THROUGH THE
PACIFIC NORTHWEST AT REGULAR INTERVALS THROUGH THE UPCOMING WEEKEND.
&&
.SHORT TERM...FAIRLY STRONG OFFSHORE GRADIENT CONTINUES THIS MORNING.
AT 16Z THE KTTD-KDLS GRADIENT WAS -9.3 MB. LOCAL STUDY SUGGESTS A
GRADIENT OF THAT MAGNITUDE PRODUCES GUSTS 35-40 KT AT KTTD...WHICH IS
PRETTY CLOSE TO REALITY. THIS IS MORE OF A GAP WIND...CONFINED TO
AREAS EAST OF INTERSTATE 205 AND NEAR THE MOUTH OF THE COLUMBIA
GORGE. AREAS IN WASHINGTON AND WEST MULTNOMAH COUNTIES SHOW MINIMAL
WIND THIS MORNING.
PORTLAND AND LANGLEY HILL DOPPLER RADARS INDICATE A RAIN BAND
EXTENDING FROM THE NEAR WILSON SUMMIT IN THE COAST RANGE TO JUST
SOUTH OF OREGON CITY MOVING TO THE NORTHEAST. THIS WILL MOVE OUT OF
THE FORECAST AREA BY 18Z. SATELLITE IMAGERY SHOWS THE PARENT LOW
SETTING UP IN THE NORTHEAST PACIFIC NEAR 50N 144W. A COUPLE LOW
CENTERS ASSOCIATED WITH THE FIRST FRONT WERE NEAR 37N 125W AND 42N
129W. EAST-LOW LEVEL FLOW WILL CONTINUE TODAY WHICH WILL RESULT IN
SPOTTY LIGHT PRECIP OVER THE FORECAST AREA. THE HIGHER CASCADES WILL
SEE SNOW...WITH THE LOWEST SNOW LEVELS NEAR THE CREST DUE TO THE
OFFSHORE GRADIENTS. CONCERN SHIFTS TO THIS EVENING AND
TONIGHT...PRIMARILY COASTAL WIND THREAT. A STRONGER WAVE REACHES THE
OREGON COAST TONIGHT...BUT PRESENTS SOME FORECAST COMPLICATIONS. THE
OFFSHORE SURFACE COMPONENT CONTINUES...EVEN ALONG THE COASTLINE.
HOWEVER...THE NAM CONTINUES TO SHOW ROBUST 850MB AND 925MB WIND
SPEEDS. 12Z THU THE LATEST NAM SHOWS A SWATH OF 80 KT 850 MB WIND
ALONG THE OREGON COAST WITH 65-75 KT AT 925MB OVER THE CENTRAL OREGON
COAST. MODEL WIND SPEEDS DIMINISH ON THE COAST AND JUST INLAND. THIS
IS NOT A CLASSIC BARRIER JET SITUATION AND NOT A PRIME COASTAL HIGH
WIND SITUATION. HOWEVER...DUE TO THE POTENTIAL FOR VERY STRONG 850 MB
AND 925 MB WIND TO SURFACE...ESPECIALLY ON THE CENTRAL OREGON
COAST...HAVE DECIDED TO UPDGRADE THE HIGH WIND WATCH TO A WARNING
THERE. HIGH WIND CONDITIONS NOT NEARLY AS FAVORABLE FOR THE NORTH
OREGON COAST AND DECIDED TO DROP THE WATCH. THE SYSTEM TONIGHT AND
THU IS WETTER BUT THE SNOW LEVELS WILL STILL BE RELATIVELY
HIGH...AGAIN LOWEST NEAR THE CASCADE CREST.
ONCE THE MAIN FRONTAL BAND MOVES ONSHORE THU EVENING...MODELS SUGGEST
INCREASED INSTABILITY OVER THE COASTAL WATERS AND ALONG THE COAST.
NAM BUFR SOUNDING FOR KAST INDICATES LI OF 0...SWEAT INDEX OF 276
WITH A FAIRLY LOW LCL. IN ADDITION...MODEL SOUNDING PROVIDES PLENTY
OF LOW-LEVEL SPEED SHEAR (15 KT NEAR THE SURFACE TO 50 KT AROUND 2000
FT EARLY THU EVENING). WILL LIKELY BE ADDING THUNDER TO THE GRIDS IN
THE AFTERNOON FORECAST. WEISHAAR
.LONG TERM...NO CHANGES. PREVIOUS DISCUSSION FOLLOWS...FRIDAY NIGHT
THROUGH TUESDAY...CLOSED UPPER LOW AND LONG WAVE TROUGH THAT HAVE
BEEN ANCHORED IN THE GULF OF ALASKA WILL FINALLY BEGIN TO PROGRESS
SLOWLY EASTWARD ON SATURDAY...BUT NOT BEFORE PUSHING A FEW MORE SHORT
WAVES ONSHORE FROM FRIDAY NIGHT THROUGH THE WEEKEND. THE MOST
VIGOROUS SHORT WAVE IN THE EXTENDED FORECAST WILL COME THROUGH
SATURDAY NIGHT INTO SUNDAY. THIS WAVE WILL BE ACCOMPANIED BY A
TROPICAL MOISTURE TAP...AND ALSO GET UPPER LEVEL SUPPORT FROM THE
LONG WAVE TROUGH AND COLD FRONT MOVING INLAND. THEREFORE...EXPECT THE
HEAVIEST PRECIPITATION AND HIGHEST AMOUNTS DURING THIS TIME. THE
UPPER TROUGH QUICKLY MOVES EASTWARD AFTER IT COMES ONSHORE
SUNDAY...REPLACED BY UPPER LEVEL RIDGING BY MONDAY AS THE LONG WAVE
TROUGH BECOMES RE-ESTABLISHED IN THE GULF OF ALASKA. MOISTURE WILL
CONTINUE TO PUSH INTO THE AREA THROUGH THE RIDGE...SO WHILE
TEMPERATURES WILL BE RISING EARLY NEXT WEEK...PRECIPITATION IS LIKELY
TO CONTINUE. BURGESS
&&
.AVIATION...VFR CONDITIONS CONTINUE FOR MOST TAF SITES UNDER
EASTERLY FLOW. EXPECT MVFR CIGS AS THE NEXT FRONT BRINGS RAIN AND
BREEZY CONDITIONS TO THE AREA LATE THIS MORNING/AFTERNOON.
KPDX AND APPROACHES...VFR CONDITIONS WITH GUSTY EAST WINDS
PERSISTING TODAY. OCCASIONAL MODERATE RAIN WILL OCCUR BRINGING
THE CIGS BRIEFLY DOWN TO MVFR. /JBONK
&&
.MARINE...A SERIES OF STORMS ROTATING AROUND A LARGE PARENT STORM
WILL IMPACT THE AREA THROUGH THE WEEKEND. THE FIRST STORM SYSTEM
WILL SEND A SURFACE TROUGH NORTHEASTWARD ACROSS THE AREA TODAY AS IT
WEAKENS AND SPLITS. EXPECT SOLID GALE FORCE WINDS 35 TO 45 KT
THROUGH THIS EVENING...WITH A FEW MARGINAL STORM FORCE WIND GUSTS
NEAR 50 KT NOT OUT OF THE QUESTION.
THE NEXT FRONT WILL BRING STRONGER WIND POTENTIAL OVERNIGHT
TONIGHT THROUGH THURSDAY MORNING. EXPECT STORM FORCE GUSTS 50 TO
55 KT WILL MAINLY STAY OVER THE OUTER WATERS. NEAR SHORE COASTAL
JET DEVELOPMENT CONFIDENCE IS MARGINAL AT BEST AS STRONG OFFSHORE
GRADIENTS TEND TO KEEP THE JET ELEVATED. THAT SAID...A FEW GUSTS
UP TO 55 KT MAY REACH THE INNER WATERS AND ESPECIALLY FOR THE
CENTRAL OREGON WATERS AS SURFACE PRESSURE WAVES SKIRT THE
COASTLINE. FEEL DOMINANT CONDITIONS WILL REFLECT SOLID GALE AND
MENTIONED THE POSSIBILITY FOR THE HIGHER GUSTS TO MAINTAIN BOATER
AWARENESS. MAY NEED TO EXTEND THE WARNINGS THROUGH THURSDAY
AFTERNOON WITH A FINAL SURFACE MSLP WAVE CROSSING THE WATERS
BETWEEN NOON AND 4 PM BRINGING ANOTHER ROUND OF SURFACING WINDS.
ADDITIONAL GALES WILL BE POSSIBLE THROUGH WEEKEND BUT TIMING
REMAINS UNCERTAIN.
SEAS SHOULD GENERALLY HOVER BETWEEN 13 TO 18 FEET TODAY BECOMING
18 TO 22 FT AND LOCALLY TO 25 FT LATE TONIGHT THROUGH THURSDAY.
SEAS EASE QUITE A BIT THURSDAY EVENING./JBONK
