Preceding cold arctic air mass combined with Strong East winds and a moist front resulted in blizzard conditions for the Western 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.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PORTLAND OR
327 AM PST THU FEB 6 2014
.SYNOPSIS...A SNOWY DAY IS IN THE MAKING THIS MORNING...AS LOW
PRESSURE OFF THE COAST SPREADS MOISTURE OVER THE COLD ARCTIC AIR MASS
IN PLACE ACROSS THE PACIFIC NORTHWEST. NORTHWEST OREGON AND EXTREME
SOUTHWEST WASHINGTON WILL BE THE ZONE WHERE THESE TWO AIR MASSES
MEET...PRODUCING INCREASING PRECIPITATION IN THE FORM OF SNOW TODAY
INTO THIS EVENING. SIGNIFICANT SNOW ACCUMULATIONS ARE LIKELY FOR MOST
OF THE FORECAST AREA LATER TODAY THROUGH FRIDAY MORNING. A SIMILAR
SETUP WILL KEEP A DECENT CHANCE OF SNOW AT TIMES THROUGH THE
WEEKEND...AS THE COLD AIR NEVER REALLY LEAVES THE AREA. FINALLY A
MORE ORGANIZED SYSTEM WILL WARM US UP EARLY NEXT WEEK...BUT THERE MAY
BE A MESSY TRANSITION ANYTIME BETWEEN SUNDAY AND TUESDAY. THE
COLUMBIA GORGE WILL BE THE LAST TO WARM UP...BUT BY MIDWEEK IT
APPEARS THE WHOLE FORECAST AREA WILL BE BACK TO MILDER TEMPERATURES
WITH PERIODS OF RAIN FOR THE REST OF THE WEEK.
&&
.SHORT TERM...TODAY THROUGH SUNDAY...WINTER STORM WARNINGS HAVE BEEN
HOISTED ACROSS MUCH OF NORTHWEST OREGON THIS MORNING...FOR WHAT IS
SHAPING UP TO BE THE MOST SIGNIFICANT WIDESPREAD SNOW EVENT FOR THE
NORTHERN AND CENTRAL WILLAMETTE VALLEY SINCE DECEMBER 2009. OF COURSE
THE WILLAMETTE VALLEY ALBANY SOUTHWARD HAVE ALREADY HAD THEIR FIRST
SNOWSTORM OF THIS SEASON BACK IN DECEMBER 2013.
CONDITIONS WILL GRADUALLY DETERIORATE AS THE DAY PROGRESSES. NWS
DUAL-POL DOPPLER RADAR IS ALREADY BEGINNING TO PICK UP ON SOME LIGHT
PRECIPITATION ECHOES...IN THE FORM OF SNOW...MOVING ONSHORE INTO LANE
AND LINCOLN COUNTIES. ODOT WEBCAMS AROUND COTTAGE GROVE INDEED SHOW A
COATING OF FRESH SNOW. AS WAS SOMEWHAT EXPECTED...THESE ECHOES ARE
SHOWING A BIT OF A BANDED SIGNATURE...SOMEWHAT ALIGNED JUST TO THE
NORTH OF THE GREATEST AREA OF 850-700 MB FRONTOGENESIS BETWEEN THE
ARCTIC AIR MASS TO THE NE AND THE MILDER PACIFIC AIR MASS TO THE
SOUTHWEST. ALREADY THE NAM/RAP SEEM TO BE TOO FAR SOUTH WITH THIS
AREA OF MAX FGEN...AND THE 00Z/06Z GFS ANALYSES ARE CLOSER TO WHAT
APPEARS TO BE REALITY. THEREFORE WE ARE FAVORING THE LATEST GFS
RUNS...AND EVEN MORESO THE 00Z ECMWF WHICH HAS BEEN FAIRLY ROCK SOLID
WITH THE EVOLUTION OF THIS PATTERN. THE 00Z ECMWF IS WHAT GAVE US THE
CONFIDENCE TO GO OUT WITH OUR SUITE OF WARNINGS SHORTLY BEFORE 11 PM
WED EVENING.
LOOKING AT WATER VAPOR AND INFRARED IMAGERY...IT IS BECOMING APPARENT
THAT ONE SHORTWAVE IS BEGINNING TO DETACH FROM ITS PARENT LOW OUT BY
46N/130W. THIS SECONDARY WAVE IS TOUGH TO PICK OUT...BUT IT APPEARS
TO BE IN THE THICKER CLOUDS ABOUT 100 MILES WEST OF TILLAMOOK. THIS
SYSTEM IS HEADING DUE EAST...WHICH ALSO INCREASES THE CONFIDENCE
LEVEL THAT SNOW WILL INCREASE AS THE DAY PROGRESSES. INITIALLY SNOW
MAY BE SLOW TO START AS THE AIR MASS IS STARTING OFF VERY DRY. BUT
LOW-LEVEL FRONTOGENESIS WILL ONLY INCREASE ACROSS NW OREGON AS THIS
WAVE APPROACHES THE COLUMBIA GORGE...WHERE THE FREEZER DOOR REMAINS
OPEN SO TO SPEAK...AND PLENTY OF ARCTIC AIR CONTINUES TO SPILL
WESTWARD INTO THE WILLAMETTE VALLEY. THE SQUEEZE PLAY BETWEEN THESE
TWO FEATURES WILL PROBABLY LEAD TO AN PERSISTENT AND INTENSIFYING
BAND OF SNOW ACROSS A GOOD PORTION OF THE WILLAMETTE VALLEY.
ONE IMPORTANT ITEM TO NOTE. THIS SITUATION WILL LIKELY TAKE A FEW
HOURS TO EVOLVE. JUST BECAUSE IT IS NOT SNOWING WHEN IT IS TIME TO
TAKE THE KIDS TO SCHOOL OR LEAVE FOR WORK DOES NOT MEAN THAT IT WILL
NOT SNOW LATER IN THE DAY. IN FACT THE STEADIEST SNOW IS NOT EXPECTED
TO BEGIN UNTIL MIDDAY...INCREASING BEFORE THE PEAK RIGHT AROUND WHAT
WOULD BE THE THURSDAY EVENING COMMUTE.
OVERALL SNOW ACCUMULATIONS THROUGH FRI MORNING WILL PROBABLY BE IN
THE 3-7 INCH RANGE FOR MOST SPOTS...PERHAPS A BIT MORE IN THE HIGHER
TERRAIN. THE 00Z/06Z GFS...00Z ECMWF...AND 00Z GEM ARE ALL IN
AGREEMENT WITH THIS...ALONG WITH MOST OF THE ECMWF ENSEMBLES.
SOUTHWEST WASHINGTON WILL PROBABLY BE ON THE FRINGE...AND MAY SEE
LIGHTER ACCUMULATIONS...BUT WE FIGURE THERE WILL BE ENOUGH TO INCLUDE
THE LOWER COLUMBIA IN A WINTER WX ADVISORY.
IN THE GORGE...STRONG WINDS WILL PERSIST THROUGH THE DAY AS SNOW
INCREASES. WITH 3-7 INCHES OF SNOW EXPECTED LATER TODAY INTO THIS
EVENING ALONG WITH WINDS GUSTING 50-65 MPH...VISIBILITY WILL BE
REDUCED TO ZERO AT TIMES DUE TO SNOW AND BLOWING SNOW. SINCE THIS IS
A MAJOR TRAVEL CORRIDOR WITH I-84 AND WA-14...WE DECIDED TO ISSUE A
BLIZZARD WARNING FOR THE WESTERN GORGE TO HIGHLIGHT THIS THREAT.
FRIDAY WILL NOT BE THE END OF THE SNOW THREAT AS THIS SYSTEM DOES
LITTLE TO NOTHING TOWARD SCOURING OUT THE EASTSIDE COLD POOL. MODELS
SHOW GOOD AGREEMENT THAT AN ELONGATED UPPER LOW OFF VANCOUVER ISLAND
AND THE OLYMPIC PENINSULA WILL KEEP SENDING WEAKENING SYSTEMS AT US
FROM THE W-SW...WHILE THE COLD POOL EAST OF THE CASCADES ONLY SLOWLY
WANES. AS A RESULT...ANOTHER SYSTEM COULD SPREAD MORE SNOW INTO THE
WILLAMETTE VALLEY FRIDAY...THEN ANOTHER SATURDAY...WITH MODERATION
ONLY LIKELY IF ONE OF THESE SYSTEMS REMAINS STRONG WHILE MOVING
ONSHORE. THIS IS UNLIKELY WITH THE MAIN PACIFIC JET FOCUSED ON
BRINGING MUCH-NEEDED RAINFALL TO NORTHERN CALIFORNIA. THE TIMING OF
EACH OF THESE WAVES IS FAIRLY UNCERTAIN...BUT THERE IS A PRETTY GOOD
CHANCE TODAYS SYSTEM WILL NOT BE THE ONLY ONE TO HAVE A WIDESPREAD
SNOW IMPACT ON NORTHWEST OREGON IN THE COMING DAYS. TEMPS REMAIN WELL
BELOW NORMAL THROUGH SUNDAY...IT MAY TAKE UNTIL MONDAY OR TUESDAY FOR
TEMPS TO START TO REBOUND CLOSER TO NORMAL. WEAGLE
.LONG TERM...LATE SUNDAY THROUGH THURSDAY...AFTER MUCH EXCITEMENT
SUNDAY MORNING WITH FREEZING RAIN/SNOW/RAIN MIX EXPECTED FOR
LOCATIONS NORTH OF EUGENE...A MORE MILD AIRMASS SPREADS ACROSS THE
FORECAST AREA BY SUNDAY NIGHT. MODELS MAINTAIN AN EASTERLY GRADIENT
THROUGH THE COLUMBIA RIVER GORGE SUNDAY NIGHT...ALBEIT A MUCH WEAKER
GRADIENT BUT WILL STILL PUMP COLDER AIR INTO THE GORGE AND UPPER
HOOD RIVER VALLEY. THE THREAT FOR FREEZING RAIN STILL LOOKS GOOD
THROUGH EARLY MONDAY MORNING IN THE GORGE. THE NEXT FRONTAL SYSTEM
PUSHES ONSHORE MIDDAY MONDAY...FINALLY WEAKENING THE EASTERLY
GRADIENT THROUGH THE GORGE AND BRINGING ABOVE FREEZING TEMPERATURES
ACROSS THE FORECAST AREA. /27
AFTER THIS MESSY AND DIFFICULT TRANSITION OVER THE WEEKEND ALL THE
MODELS INDICATE A MAJOR PATTERN SHIFT TOWARD A WET AND PROGRESSIVE
WESTERLY JET STREAM TUESDAY THROUGH THE END OF NEXT WEEK.
&&
.AVIATION...VFR CONDITIONS WITH MOD TO STRONG OFFSHORE FLOW THIS
AM. LOW PRES WELL OFFSHORE WILL INTO THE REGION THIS AM...WITH
AREAS OF MVFR CIGS AND LIGHT SNOW GRADUALLY INCREASING THROUGH
18Z. SNOW WILL INCREASE BETWEEN 18Z AND 22Z. FLIGHT CONDITIONS
WILL DETERIORATE QUICKLY AT THAT TIME...WITH TRANSITION TO IFR
CIGS AND IFR TO MVFR IN SNOW. MTNS AND TERRAIN BECOMING OBSCURED
IN CLOUDS AND SNOW THIS AM.
KPDX AND APPROACHES...VFR THIS AM...BUT WILL HAVE A FEW FLURRIES
IN AREA TIL 16Z. FROM 16Z TO 20Z...WILL SEE OCCASIONAL LIGHT SNOW
WITH OCCASIONAL MVFR INCREASING...BUT STEADY ACCUMULATING SNOW
ARRIVES AFTER 20Z WITH IFR. MOD EAST WINDS RELAX A BIT AFTER
00Z...BUT IFR WITH LIGHT SNOW CONTS THROUGH 08Z. ROCKEY.
&&
.MARINE...OFFSHORE FLOW CONTINUES...BUT WILL GRADUALLY RELAX AS
LOW PRES MOVES ACROSS THE REGION LATER TODAY. HOWEVER...OFFSHORE
WINDS WILL INCREASE AGAIN THIS WEEKEND AS STRONG LOW APPROACHES
FROM THE SW. WINDS SHOULD PUSH 20 TO 25 KT BY LATE FRI AND AGAIN
LATE SAT AS TWO SEPARATE LOW PRES SYSTEMS DEVELOP AND PUSH
NORTHEASTWARD INTO THE PAC NW.
SEAS WILL REMAIN IN THE 5 TO 7 FT RANGE THROUGH THE WEEKEND. MAY
SEE BIT MORE IN WAY OF SWELL EARLY TO MID NEXT WEEK. ROCKEY.
