A strong Pacific cold front brought strong southerly winds to the north and central Oregon Coast.
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.
A strong Pacific cold front brought strong southerly winds to the north and central Oregon Coast.
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 30, 9:24 PM PST, 2 hours 36 minutes earlier.
AREA FORECAST DISCUSSION...CORRECTED
NATIONAL WEATHER SERVICE PORTLAND OR
924 PM PST FRI NOV 30 2012
.SYNOPSIS...A BROAD UPPER LOW OVER THE NE PACIFIC WILL CONTINUE
UNSETTLED WEATHER INTO NEXT WEEK. THE NEXT FRONT WILL MOVE THROUGH
THE AREA TONIGHT AND SATURDAY MORNING. SNOW LEVELS WILL LOWER TO PASS
LEVEL WITH THIS SYSTEM. ANOTHER FRONT WILL BRING MORE SUBSTANTIAL
CASCADE SNOW SATURDAY NIGHT AND SUNDAY.A STRONG UPPER JET WILL
CONTINUE SHOWERS THROUGH SUNDAY NIGHT. THERE WILL BE A BRIEF BREAK IN
PRECIPITATION MONDAY MORNING BEFORE ANOTHER MOIST FRONT WILL MOVE
THROUGH MONDAY NIGHT AND TUESDAY.
&&
.SHORT TERM...A VIGOROUS VORT MAX AND SHORTWAVE TROUGH MOVING INTO
WEST COAST ARE RESPONSIBLE FOR RAIN SHOWERS LIFTING NORTHEASTWARD
ACROSS THE REGION THIS EVENING. SO FAR RAIN IS PRIMARILY CONFINED
ACROSS THE NORTHWESTERN HALF OF THE CWA...BUT EXPECT THIS BROAD BAND
OF PRECIPITATION TO SHIFT SOUTHEASTWARD AS THE NIGHT PROGRESSES. SNOW
LEVELS NEAR 5000-5500 FT THIS EVENING SHOULD DROP TO NEAR 4000 FT BY
MORNING WITH 5 TO 8 INCHES OF NEW SNOW EXPECTED
ISOLATED THUNDERSTORMS HAVE BEEN DEVELOPING ACROSS OUR WATERS WITH A
FEW BEGINNING TO PUSH ASHORE NEAR BAY CITY AND TILLAMOOK. AN EVEN
MORE NOTEWORTHY CLUSTER OF THUNDERSTORMS HAS ERUPTED WEST OF COOS
BAY. IT APPEARS THIS CLUSTER WILL LIFT EAST-NORTHEASTWARD INTO THE
SOUTH CENTRAL OREGON COAST. AS A RESULT OF ALL THIS
ACTIVITY...THUNDER WAS ADDED TO THE OVERNIGHT FORECAST FOR THE COAST
RANGE AND THE SOUTH WILLAMETTE VALLEY.
NUMEROUS SITES HOVERED IN THE 45 TO 55 MPH RANGE FOR WIND GUSTS THIS
EVENING. THE RUC SEEMED TO INDICATE THE HIGH WINDS WERE ABOUT TO
SUBSIDE AND THAT WE WERE GOING TO ESCAPE UNSCATHED...JUST BEFORE
SEVERAL SITES REACHED HIGH WIND CRITERIA ALONG THE COAST. THESE
INCLUDED LINCOLN CITY...THE YAQUINA BRIDGE AND GARIBALDI. THIS
COINCIDED NICELY WITH AN INFLUX OF 65 TO 75KT INBOUND RETURNS AT
APPROXIMATELY 7500 FT VIA THE KRTX RADAR. WINDS APPEAR TO HAVE
TEMPORARILY BACKED OFF ALOFT VIA RADAR...BUT AN ADDITIONAL SPIKE IN
WINDS IN ANOTHER HOUR OR TWO ASSOCIATED WITH THE NEXT BAND OF
CONVECTION SEEMS PLAUSIBLE.
NO FLOODING IS ANTICIPATED DUE TO THE RAINFALL EXPECTED OVERNIGHT.
WITH THAT SAID...THE GRAYS RIVER AT ROSBURG IS BEGINNING TO GO UP
SOMEWHAT SHARPLY SO THIS WILL BE MONITORED CLOSELY OVERNIGHT.
/NEUMAN
PREVIOUS DISCUSSION BELOW...A LARGE COMPLEX UPPER LOW OVER THE NE
PACIFIC WILL CONTINUE TO SEND SYSTEMS ACROSS THE REGION INTO NEXT
WEEK. CONVECTIVE SHOWERS WILL CONTINUE GUSTY AND SHOWERY WEATHER LATE
THIS AFTERNOON...ESPECIALLY FOR THE COAST AND COAST RANGE. THE
SHOWERS WILL RAMP UP THIS EVENING AS THE NEXT SYSTEM...CURRENTLY NEAR
43N 134W APPROACHES. THIS SYSTEM WILL BRING ANOTHER ROUND OF GUSTY
WINDS AND HEAVY RAIN TONIGHT.
COOLER AIR WILL MOVE IN BEHIND THE FRONT WITH 700 MB MODELED
TEMPERATURES COOLING TO -9C BETWEEN 4 AND 10 PST SATURDAY MORNING.
SNOW LEVELS WILL LOWER TO NEAR OR JUST BELOW PASS LEVEL EARLY
SATURDAY MORNING. ALTHOUGH THE MAIN RAIN BAND WILL HAVE PUSHED
THROUGH BY THEN...A 120KT PLUS JET WILL CONTINUE SHOWERS THROUGH
SATURDAY AND EXPECT SOME DECENT SNOW ACCUMULATIONS AT THE PASSES
SATURDAY MORNING. THE SOUTH WASHINGTON CASCADES WILL HAVE THE HIGHEST
SNOW AMOUNTS AND HAVE ISSUED A LOW-END WINTER WEATHER ADVISORY FOR
TONIGHT THROUGH SATURDAY.
SHOWERS WILL LIGHTEN UP BRIEFLY SATURDAY AFTERNOON BEFORE THE NEXT.
SYSTEM...CURRENTLY NEAR 43N 148W CONTINUES THE UNSETTLED WEATHER.
THERE IS MORE MOISTURE WITH THIS SYSTEM THEN THE FEW PREVIOUS ONES
WITH MODELED TROPICAL PRECIPITABLE WATER VALUES NEAR AN INCH...AND
EXPECT SLIGHTLY MORE PRECIPITATION WITH THE FRONT EARLY SUNDAY
MORNING.THERE IS ALSO A STRONGER JET (150 +KT) BACKING UP THIS
SYSTEM THAT WILL RESULT IN MORE SUBSTANTIAL POST-FRONTAL SHOWERS
SUNDAY AFTERNOON AND NIGHT.
THE LOW HAS A FAVORABLE STORM TRACK FOR PRODUCING STRONG INLAND
WINDS...BUT THE MODELS HAVE BEEN BACKING OFF ON THE STRENGTH OF THE
LOW AND CURRENTLY THINK THE WINDS WILL REMAIN BELOW WARNING...BUT
GUSTY FOR SURE.
SNOW LEVELS WILL NOT RECOVER MUCH BETWEEN THE SATURDAY AND SUNDAY
SYSTEMS AND EXPECT MORE ABUNDANT SNOW IN THE CASCADES. THERE WILL BE
AT LEAST SOLID ADVISORY SNOW FROM SATURDAY NIGHT THROUGH SUNDAY
AFTERNOON...BUT WARNING AMOUNTS ARE NOT OUT OF THE QUESTION AND HAVE
ISSUED A WINTER STORM WATCH FOR ALL OF THE CASCADES.
SHOWERS WILL LIGHTEN UP SOME MONDAY MORNING...BUT WILL NOT END ALL
TOGETHER AS ANOTHER LOW WILL DROP DOWN INTO THE NE PACIFIC AND
BRING ANOTHER POTENTIALLY MOIST STORM MONDAY AFTERNOON AND EVENING.
.LONG TERM...MONDAY NIGHT THROUGH FRIDAY...MODEL GUIDANCE IS SHOWING
REASONABLY GOOD AGREEMENT THROUGH THE FIRST HALF OF NEXT WEEK. THE
LATEST MEDIUM RANGE MODEL RUNS HAVE SPED UP THE PROGRESSION OF THE
NEXT FRONTAL SYSTEM. NOW EXPECT PRECIPITATION TO BEGIN SPREADING INTO
THE COAST MONDAY NIGHT...THEN PROGRESS INLAND DURING THE DAY TUE. IT
APPEARS THAT THIS FRONT WILL MAINTAIN A CONNECTION TO TROPICAL
MOISTURE. MODEL PWAT VALUES OF 1 TO 1.25 INCHES COMBINED WITH A
STRONG LOW LEVEL JET ARE EXPECTED TO BRING FAIRLY IMPRESSIVE MOISTURE
TRANSPORT INTO THE REGION. A MODERATE-TO-HEAVY RAINFALL EVENT IS
LOOKING LIKELY AT THIS POINT...WITH THE POTENTIAL FOR SOME GUSTY
COASTAL WINDS. HOWEVER...AT THIS POINT THE FOCUS OF THE HEAVIEST RAIN
APPEARS TO REMAIN TO OUR SOUTH...ALONG THE CA/OR BORDER...SO WE MAY
AVOID SIGNIFICANT HYDROLOGIC ISSUES. THE HEAVY RAINFALL SHOULD TAPER
OFF LATER TUE AS THE FRONT PUSHES EAST...BUT EXPECT SHOWER ACTIVITY
TO CONTINUE OVERNIGHT TUE AND WED AS THE PARENT UPPER TROUGH PUSHES
THROUGH THE PAC NW. WE SHOULD TREND DRIER OVER THE SECOND HALF OF THE
WEEK AS WEAK UPPER LEVEL RIDGING BUILDS IN BEHIND THE DEPARTING
TROUGH. PYLE
&&
.AVIATION...COOL MOIST AND UNSTABLE AIR MASS REMAINS OVER THE
REGION. W TO SW FLOW ALOFT CONTINUES WITH EMBEDDED DISTURBANCES
THESE DISTURBANCES WILL ENHANCE THE SHOWER BANDS THIS AFTERNOON
FOR THE COAST...AND FOR MOST AREAS AGAIN LATER THIS EVENING.
EXPECT MVFR CHANCES WILL BE MOST PERSISTENT ALONG THE COAST
THROUGH THE PERIOD...WITH THE BEST MVFR CHANCES INLAND OVERNIGHT.
BEST THREAT FOR TSTORMS REMAINS FROM COAST RANGE WESTWARD...WITH A
SMALL CHANCE OF IMPACTING THE COASTAL TERMINALS MAINLY DURING THE
LATE EVENING AND OVERNIGHT HOURS AS THE NEXT STRONGER FRONT MOVES
IN. TSTORM THREAT SHIFTS NORTH OF THE COLUMBIA RIVER SUNDAY
MORNING.
KPDX AND APPROACHES...VFR CONDITIONS WITH INTERMITTENT SHOWERS
THROUGH THIS EVENING...WITH BRIEF MVFR UNDER THE SHOWERS. BETTER
CHANCE FOR MVFR IN RAIN OVERNIGHT. GUSTY S TO SE WINDS WILL
CONTINUE THROUGH THE PERIOD...THOUGH MAINLY GUSTS TO 25 KT OR
LESS...POSSIBLY HIGHER AT TIMES OVERNIGHT. VFR RETURNS SATURDAY AS
FRONT CLEARS THE TERMINAL BY DAYBREAK. KMD/BROWN
&&
.MARINE...STRONG LOW PRESSURE OFFSHORE OF THE TIP OF VANCOUVER
ISLAND WILL SLOWLY WEAKEN THROUGH THE WEEKEND...BUT A FAIRLY
STRONG PRESSURE GRADIENT WILL REMAIN DRAPED OVER THE WATERS. THIS
COMBINED WITH SHOWER ACTIVITY FROM A SERIES OF FRONTS MOVING
THROUGH THE WATERS TONIGHT AND AGAIN SATURDAY WILL CREATE GALE
FORCE GUSTS THROUGH THE DAY ON SATURDAY. GALES MAY WEAKEN AT
TIMES.
SEAS WILL REMAIN IN THE 16 TO 18 FT RANGE THROUGH SAT...THOUGH
MAY GET UP TO 19-20 FT TONIGHT WITH A FRONTAL PASSAGE AND
ESPECIALLY ACROSS THE CENTRAL OREGON WATERS. SEAS GRADUALLY
SUBSIDING ON SUN INTO MON BACK INTO THE LOWER TEENS...BUT
CONFIDENCE IS LOW ON SEAS DROPPING BACK BELOW 10 FT FOR ANY
EXTENDED PERIOD UNTIL THE LATTER HALF OF NEXT WEEK WHEN HIGH
PRESSURE ATTEMPTS TO BUILD IN. KMD/BROWN
