AFTER COLD WEATHER HAD LASTED MUCH OF NOVEMBER, THIS COLD BEGAN TO
EASE UP A BIT AS THE CALENDAR CHANGED TO DECEMBER. THE FIRST WEEK
SAW TEMPERATURES WARMING INTO THE 40S AND EVEN THE 50S. BUT THIS
BRIEF BREAK FROM THE COLD WAS NOT GOING TO LAST. THE FIRST
SIGNIFICANT SNOWSTORM OF THE SEASON ARRIVED ON DECEMBER 9 WHEN MORE
THAN 5 INCHES OF SNOW FELL. THIS SNOW WOULD ULTIMATELY PROVE TO BE A
KEEPER THAT REMAINED ON THE GROUND THROUGH THE REST OF THE SEASON.
COLDER TEMPERATURES SOON BECAME THE NEW NORMAL WITH THE NEXT SEVERAL
STORM SYSTEMS BRINGING SNOW FOLLOWED BY FREEZING RAIN. THE NEXT
SIGNIFICANT SNOWSTORM ARRIVED CHRISTMAS MORNING WITH 6 INCHES OF
SNOW FALLING IN JUST A FEW HOURS. BRUTALLY COLD ARCTIC AIR POURED IN
BEHIND THIS STORM WITH THE TEMPERATURE NOT RISING ABOVE FREEZING
AGAIN FOR 15 DAYS. THIS WAS THE MOST INTENSE AND LONG LASTING ARCTIC
BLAST IN THE SHORT 23-YEAR HISTORY OF OBSERVATIONS AT THE NATIONAL
WEATHER SERVICE OFFICE IN GRAY. FOR 7 STRAIGHT DAYS THE TEMPERATURE
DID NOT WARM ABOVE 15 DEGREES AND THE TEMPERATURE FELL BELOW ZERO
EACH NIGHT. FOUR OF THE TOP 5 COLDEST DECEMBER TEMPERATURES ON
RECORD WERE OBSERVED. JUST AS TEMPERATURES WARMED BACK INTO THE MID
20S, AN INTENSE STORM SYSTEM BROUGHT 12 INCHES OF SNOW ON JANUARY 4
ACCOMPANIED BY BLIZZARD CONDITIONS. A REINFORCING SHOT OF BRUTAL
COLD POURED IN AGAIN AFTER THIS STORM WITH 3 MORE NIGHTS OF SUBZERO
TEMPERATURES. IN FACT, THE TEMPERATURE DID NOT EVEN WARM ABOVE ZERO
ON JANUARY 6. FINALLY THE INTENSE COLD BEGAN TO BREAK AND THE
TEMPERATURE ROSE ABOVE FREEZING AGAIN FOR THE FIRST TIME ON JANUARY
9, JUST AS THE JANUARY THAW BEGAN. THE NEXT 4 DAYS BROUGHT WARMING
TEMPERATURES. THE TEMPERATURE PEAKED AT 52 DEGREES ON THE 13TH AS
WARM AIR AND HEAVY RAINFALL SURGED NORTHWARD AHEAD OF A STRONG COLD
FRONT. THE STRONG COLD FRONT BROUGHT A RETURN TO VERY COLD WEATHER
FOR A FEW DAYS, THOUGH THIS COLD SPELL WAS NOT AS INTENSE OR AS LONG
LASTING AS THE LAST ONE. MORE SNOW FELL ON JANUARY 17TH, HELPING TO
REPLENISH THE EARLY SEASON SNOW COVER WHICH HAD BEEN DIMINISHED FROM
THE JANUARY THAW. FOR THE NEXT FEW WEEKS THE TEMPERATURE GRADUALLY
BEGAN WARMING AGAIN WITH THE EXCEPTION OF SOME LIGHT SNOW AND
FREEZING RAIN ON JANUARY 22 AND 23. SOME COLDER AIR RETURNED AT THE
END OF JANUARY INTO THE BEGINNING OF FEBRUARY WITH THE COLDEST
TEMPERATURE FROM THIS COLDER SPELL BEING 4 BELOW ZERO ON FEBRUARY 3.
ULTIMATELY THIS PROVED TO BE THE LAST SIGNIFICANT COLD SPELL OF THE
WINTER. MUCH OF FEBRUARY SAW WARMING TEMPERATURES WITH JUST ENOUGH
PERIODIC WINTRY SET BACKS TO KEEP A SEVERAL INCHES OF SNOW ON THE
GROUND. THE TWO BIGGEST SNOWSTORMS CAME ON FEBRUARY 7 AND 18 WITH
EACH ONE BRINGING MORE THAN 6 INCHES OF SNOW. THE GRADUAL WARMING
INTENSIFIED IN THE LAST PART OF THE MONTH AS A RIDGE OF HIGH
PRESSURE BROUGHT WARM AIR FROM THE SOUTHERN UNITED STATES INTO NEW
ENGLAND. THIS WARMTH PEAKED WITH A TEMPERATURE OF 68 DEGREES ON
FEBRUARY 21, THE WARMEST TEMPERATURE EVER OBSERVED IN THE MONTH OF
FEBRUARY. ALTHOUGH A COLD FRONT THAT EVENING BROUGHT COOLER
TEMPERATURES BACK INTO THE AREA, THE REST OF THE MONTH REMAINED
ABOVE NORMAL WITH MOST DAYS REACHING THE 40S. BY THE END OF THE
FEBRUARY ONLY 6 INCHES OF SNOW WAS LEFT ON THE GROUND.

THE AVERAGE TEMPERATURE FOR THE MONTH WAS 23.8 DEGREES WHICH WAS 0.5
DEGREES BELOW NORMAL. THE COLDEST WINTER ON RECORD WAS IN 2014-15
WHEN THE AVERAGE TEMPERATURE WAS 19.8 DEGREES. THE WARMEST WAS IN
2001-02 WHEN IT WAS 29.8 DEGREES. THE HIGH TEMPERATURE OF 68 DEGREES
ON FEBRUARY 21 WAS THE SECOND WARMEST WINTER TEMPERATURE ON RECORD.
THE FOLLOWING TABLE LISTS THE WARMEST WINTER TEMPERATURES AT GRAY.

A TOTAL OF 10.64 INCHES OF PRECIPITATION FELL WHICH WAS 0.26 INCHES
