What happened

The episode as NWS PDT wrote it up.

Modified arctic air moved into the region followed by a series of moderate to strong upper level storm systems riding on a moist subtropical jet stream. The result was widespread heavy snow and local high winds. Freezing rain and sleet accumulated to between 1/4 and 1/2 inch over the lower elevations.

On January 17 and 18, snowfall amounts reported in inches included Waitsburg (6), 5 miles north northwest of Wiley City (6), 18 miles west northwest of West Richland (5), 8 miles west northwest of Connell (4), 2 miles west of Yakima (5), Toppenish (6), 1 mile southwest of Yakima (5), 5 miles north northwest of Centerville (15), 9 miles northwest of Roslyn (23), 3 miles north northeast of Ellensburg (4), Yakima (4), 7 miles northeast of Goldendale (14.5), 4 miles east northeast of White Salmon (18), 1 mile south southwest of Yakima (4), Cle Elum (7), Dayton (7.5), Ski Bluewood (18), Goldendale (12), 1 mile west northwest of White Salmon (17), Glenwood (10), 1 mile east of Walla Walla (5), 5 miles north of White Salmon (10.2), Mount Adams Ranger Station (17), Snowden (18), Easton (14), Tampico (11), 2 miles east south of West Valley (5.5), 4 miles east northeast of Yakima (4), Waitsburg (7), Richland (6), 15 miles northeast of Pasco (7.5), 10 miles east of Goldendale (13), 1 mile west of Toppenish (5), Kennewick (7.8), 3 miles northeast of College Place (4), West Richland (7), 5 miles south of Sunnyside (5), 20 miles west of Prescott (7), Selah (5), White Salmon (16), 6 miles east of White Swan (5.5), West Valley (7), Sunnyside 4.5), 10 miles north of Pasco (4), 1 mile southwest of Ellensburg (4), and 2 miles northeast of Husum (10.2).

On January 19-20, another surge of subtropical Pacific moisture moved over the cold air with a widespread mixture of precipitation. The lower elevations received freezing rain mixed at times with sleet and snow. The higher elevations received heavy snowfall. The storm caused numerous vehicle accidents with injuries, downed tree branches, power outages, and closed roads and schools.

Ice accumulation reported in inches included Kennewick (.5), 1 mile west of Patterson (.25), Dayton (.5), Walla Walla (.5), 3 miles northeast of Dallesport (.38), 1 mile west northwest of White Salmon (.25).

AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE PENDLETON OR
400 PM PST MON JAN 16 2012

UPDATED AVIATION DISCUSSION

.SHORT TERM...TONIGHT THROUGH WEDNESDAY...THE COLD, MOIST WEST FLOW
WILL PERSIST THROUGH TUESDAY. ISOLATED TO SCATTERED SNOW SHOWERS CAN
BE EXPECTED TO PERSIST ACROSS THE AREA TONIGHT. HIGHEST COVERAGE OF
SHOWERS WILL BE OVER THE BLUE MOUNTAINS DUE TO UPSLOPE AFFECTS AND
ALONG THE CASCADE EAST SLOPES WHERE SLOP OVER OF SHOWERS WILL
INCREASE OVERNIGHT. THE INCREASE IN SHOWERS ALONG THE CASCADE EAST
SLOPES, ESPECIALLY NEAR THE CREST, WILL BE SUFFICIENT ENOUGH TO
CAUSE SIGNIFICANT SNOW ACCUMULATIONS. THUS WILL CONTINUE THE WARNING
FOR THE WASHINGTON EAST SLOPES AND ADD A WARNING FOR THE OREGON EAST
SLOPES. SHOWERS WILL CONTINUE TO DRIFT EAST ACROSS THE AREA TUESDAY.
THE SHOWER ACTIVITY WILL BEGIN TO PRODUCE LIGHT ACCUMULATIONS IN THE
KITTITAS AND YAKIMA VALLEYS, THE SIMCOE HIGHLANDS AND THE COLUMBIA
RIVER GORGE IN THE MORNING. MEANWHILE PERSISTENT LIGHT ACCUMULATIONS
SHOULD START IN THE BLUE MOUNTAINS DURING THE AFTERNOON. AS SUCH
WILL UPGRADE WATCHES IN THESE AREAS TO WARNINGS. INCREASING PRESSURE
GRADIENTS LATE TONIGHT INTO TUESDAY WILL CAUSE BREEZY TO WINDY
SOUTHWEST WINDS. THESE WINDS WILL HELP BOOST TEMPS INTO THE UPPER
30S TO MID 40S. MOISTURE AND ENERGY WILL INCREASE TUESDAY NIGHT INTO
WEDNESDAY AS A SYSTEM WILL MOVE ALONG A WARM FRONT AHEAD OF A
BUILDING RIDGE OFFSHORE. THUS WILL SEE PERSISTENT SNOW DEVELOP
TUESDAY NIGHT, CONTINUING INTO WEDNESDAY. WILL CONTINUE CURRENT
WATCHES AND ADD WALLOWA COUNTY, THE JOHN DAY BASIN AND THE JOHN
DAY-OCHOCO HIGHLANDS TO THE WATCH LIST. THE TRACK OF THE SURFACE LOW
WEDNESDAY IS STILL IN DOUBT THOUGH IT IS BEGINNING TO LOOK AS THOUGH
IT MAY TRACK ALONG THE OREGON/WASHINGTON BORDER. THUS WILL SEE SNOW
LEVELS RISE WEDNESDAY AFTERNOON OVER CENTRAL OREGON. SNOW LEVELS MAY
RISE OVER OTHER PORTIONS OF NORTHEAST OREGON, BUT SURFACE TEMPS MAY
REMAIN NEAR 32 DEGREES. THUS WILL MENTION SOME POSSIBILITY OF
FREEZING RAIN OVER PORTIONS OF NORTHEAST OREGON. 90

.LONG TERM...WEDNESDAY NIGHT THROUGH MONDAY...A VERY MOIST FRONTAL
SYSTEM WILL BE SENDING A FRONT THROUGH THE AREA WEDNESDAY NIGHT WITH
ABUNDANT PRECIPITATION OF UP TO A QUARTER INCH IN MOST LOCATIONS
THOUGH LESS THAN A TENTH IS EXPECTED IN THE COLUMBIA BASIN. SNOW
LEVELS IN CENTRAL OREGON WILL BE AT OR ABOVE 5000 FEET AND SOUTH OF
THE COLUMBIA RIVER AT 2500 TO 5000 FEET, SO ALL RAIN IS EXPECTED
THERE. FURTHER NORTH COLD AIR WILL STILL BE LOW IN THE EVENING SO A
WINTERY MIX OF SNOW AND FREEZING RAIN WILL BE POSSIBLE IN THE LOWER
ELEVATIONS OF WASHINGTON UNTIL AROUND MIDNIGHT WHEN IT WILL SWITCH
OVER TO ALL RAIN. THURSDAY WILL SEE ANOTHER SHOT OF MOISTURE
ARRIVING WITH RAIN EXPECTED EVERYWHERE EXCEPT THE HIGHEST MOUNTAIN
LOCATIONS. SOUTHWEST WINDS OF 15 TO 25 MPH WILL BE OVER THE AREA
WEDNESDAY NIGHT AND THURSDAY AND DOWNSLOPING WINDS WILL HELP GIVE
MOST OF OREGON LOW TEMPERATURES WEDNESDAY NIGHT ABOVE FREEZING AND
TEMPERATURES IN WASHINGTON WILL REMAIN MAINLY IN THE 20S. ON
THURSDAY THE WINDS WILL WARM CENTRAL OREGON AND THE COLUMBIA BASIN
INTO THE 40S. SHOWERY CONDITIONS ARE EXPECTED THURSDAY NIGHT AND
FRIDAY MORNING BEFORE ANOTHER SYSTEM ARRIVES THURSDAY AFTERNOON AND
THURSDAY NIGHT. A BRIEF BREAK IS EXPECTED FRIDAY BEFORE ANOTHER
SYSTEM ARRIVES FRIDAY NIGHT AND SATURDAY. MODELS BEGIN TO DIVERGE AT
THIS POINT BUT CONTINUED SHOWERY CONDITIONS ARE EXPECTED THROUGH
MONDAY. TEMPERATURES FRIDAY WILL BE SIMILAR TO THURSDAY BUT THEN
WILL COOL TO THE LOWER 30S TO LOWER 40S SATURDAY THROUGH MONDAY.
FREQUENT BREEZY WINDS ARE EXPECTED THROUGH THE PERIOD. PERRY

.AVIATION...00Z TAFS...VFR CONDITIONS WILL BE PREVALENT THROUGH
EARLY THIS EVENING WITH CEILINGS AT 4000-7000 FEET AND DEVELOPING
ISOLATED SNOW AND RAIN SHOWERS. THIS EVENING CEILINGS WILL LOWER TO
3500-6000 AND ISOLATED SNOW SHOWERS WILL CONTINUE. OCCASIONAL
MVFR/VFR CEILINGS AND VISIBILITIES ARE EXPECTED AT MOST TAF SITES
AFTER 09Z. AFTER 15-18Z, SHOWERS WILL BECOME SCATTERED AND CHANGE
FROM SNOW TO RAIN WITH MVFR/VFR CEILINGS CONTINUING THROUGH 00Z.
SURFACE WINDS AT KPSC, KALW AND KPDT WILL CONTINUE AT 10 TO 20 KTS
WITH GUSTS TO 25 KTS TONIGHT THEN BEGIN INCREASING AFTER 12Z,
REACHING 15 TO 25 KTS WITH GUSTS TO 35 KTS AFTER 20Z. OTHER TAF
SITES WILL GENERALLY REMAIN BELOW 15 KTS (BUT OFTEN CLOSE TO 15 KTS)
FOR THE NEXT 24 HOURS. HOWEVER, KRDM AND KBDN WILL ALSO INCREASE
AFTER 12Z AND WILL REACH 15 TO 25 KTS WITH GUSTS TO 35 KTS AFTER 20Z
TOMORROW MORNING. PERRY
