THE WINTER SEASON BEGINS DECEMBER 1, BUT MOST RESIDENTS WOULD TELL
YOU WINTER CAME EARLY THIS YEAR. AFTER 3 SNOWSTORMS IN NOVEMBER AND
SOME BRUTAL COLD TEMPERATURES, THE WINTER SEASON ACTUALLY BEGAN WITH
A BRIEF BREAK FROM THE COLD. WARM WEATHER AND SOME RAIN MELTED THE
LAST OF THE NOVEMBER SNOWS, BUT A COLD FRONT ON DECEMBER 3 BROUGHT
THE COLD AIR BACK IN. THE NEXT TWO WEEKS WERE DRY AND COLD. PORTLAND
WENT NEARLY TWO WEEKS WITHOUT PRECIPITATION, A STARK DEPARTURE FROM
THE LATE FALL TREND. WHILE THERE WERE SEVERAL DAYS THAT ONLY GOT UP
TO AROUND FREEZING FOR A HIGH, IT WAS NOT NEARLY AS COLD AS WHAT WAS
OBSERVED A FEW WEEKS EARLIER AT THANKSGIVING. THE COLD BROKE ON
DECEMBER 14 AS WARM AIR MOVED INTO THE AREA. A LITTLE LIGHT SNOW A
FEW DAYS LATER DID NOT LAST LONG AS MORE WARM AIR AND RAIN WASHED IT
ALL AWAY BEFORE CHRISTMAS. A FEW MORE LIGHT SNOWS CAME AFTER
CHRISTMAS AND INTO THE BEGINNING OF THE NEW YEAR, HELPING TO
REESTABLISH A MINOR SNOW COVER. A SNOWSTORM ON JANUARY 19 AND 20
BROUGHT NEARLY 6 INCHES OF SNOW AND SLEET WITH SOME BITTER COLD AIR
MOVING IN BEHIND IT. THE COLD DIDN`T LAST LONG, THOUGH, AS THE
JANUARY THAW WAS A FEW DAYS AWAY. MORE THAN 1.5 INCHES OF RAIN FELL
ON JANUARY 24 WITH THE TEMPERATURE REACHING 50 DEGREES. IT COOLED
BACK DOWN AGAIN THE NEXT DAY, AND BY THE END OF JANUARY ANOTHER
SNOWSTORM BROUGHT 5 MORE INCHES OF SNOW WITH ARCTIC AIR MOVING IN
AGAIN. THIS AIR MASS EVENTUALLY BROUGHT PORTLAND IT`S COLDEST
TEMPERATURE OF THE WINTER ON FEBRUARY 2 WHEN IT REACHED 2 BELOW
ZERO. BUT JUST A FEW DAYS LATER ANOTHER BRIEF SHOT OF WARM AIR
BROUGHT PORTLAND ALL THE WAY UP TO 62 DEGREES ON FEBRUARY 5 PUTTING
A BIG DENT IN THE MEAGER SNOW COVER. A WINTER STORM ON FEBRUARY 12
AND 13 BROUGHT MORE THAN 7 INCHES OF SNOW AND SLEET. THE REST OF
FEBRUARY SAW STORM SYSTEMS TRACKING MOSTLY TO THE WEST BRINGING
LIGHT SNOW CHANGING TO FREEZING RAIN AND RAIN BEFORE ANOTHER COLD
FRONT WOULD BRING A RETURN TO COLD CONDITIONS. THE FREQUENT SHOTS OF
LIGHT SNOW AND COLD HELPED MAINTAIN THE SNOW PACK THROUGH THE END OF
FEBRUARY. THE GREATEST SNOW DEPTH THIS WINTER WAS ONLY 7 INCHES ON
FEBRUARY 13 AND 14, ALTHOUGH IT WAS SLIGHTLY HIGHER (8 INCHES) IN
NOVEMBER JUST BEFORE THANKSGIVING.

THE AVERAGE TEMPERATURE FOR THE SEASON WAS 26.3 DEGREES WHICH WAS
0.7 DEGREES ABOVE NORMAL. THE WARMEST WINTER WAS IN 2001-02 WHEN THE
AVERAGE TEMPERATURE WAS 31.3 DEGREES. THE COLDEST WAS IN 1970-71
WHEN IT WAS ONLY 17.9 DEGREES.

A TOTAL OF 13.13 INCHES OF PRECIPITATION FELL WHICH WAS 2.48 INCHES
ABOVE NORMAL AND THE 7TH CONSECUTIVE WETTER THAN NORMAL WINTER. THE
HEAVIEST PRECIPITATION CAME DURING THE JANUARY THAW WHEN 1.56 INCHES
OF RAIN FELL ON JANUARY 23 AND 24. THE WETTEST WINTER WAS IN 1934-35
WHEN 20.49 INCHES FELL. THE DRIEST WAS IN 1871-72 WHEN ONLY 4.12
INCHES WAS MEASURED.

THERE WAS 35.2 INCHES OF SNOWFALL WHICH WAS 9.3 INCHES BELOW NORMAL
AND THE FIRST WINTER WITH LOWER THAN NORMAL SNOWFALL SINCE 2012. THE
HEAVIEST SNOWFALL OF THE WINTER CAME ON FEBRUARY 12 AND 13 WHEN 7.7
INCHES OF SNOW AND SLEET WAS OBSERVED. THE LEAST SNOWY WINTER WAS IN
1936-37 WHEN ONLY 9.5 INCHES FELL. THE SNOWIEST WAS IN 1970-71 WHEN
107.6 INCHES FELL.
