AS 2015 BEGAN, THE WEATHER PATTERN BEGAN TO SHIFT AND COLDER AIR
BEGAN ARRIVING IN NEW ENGLAND. BY JANUARY 8TH THE TEMPERATURE FELL
TO 13 DEGREES BELOW ZERO, THE COLDEST TEMPERATURE OF THE YEAR, AND
THE COLDEST TEMPERATURE OBSERVED AT THE NATIONAL WEATHER SERVICE
OFFICE IN GRAY SINCE 2004. AFTER A BRIEF WARM UP IN MID JANUARY, THE
COLD WEATHER RETURNED IN FORCE AND DID NOT LET UP AGAIN UNTIL MARCH.
A PERSISTENT STORM TRACK BROUGHT FRESH SNOWFALL EVERY FEW DAYS FROM
JANUARY 24TH THROUGH MARCH 4TH ALONG WITH PERSISTENTLY FRIGID
TEMPERATURES. THE BIGGEST SNOWSTORM WAS ON JANUARY 27TH AND 28TH
WHEN 26.6 INCHES OF SNOW FELL ALONG WITH BLIZZARD CONDITIONS. THE
BLIZZARD AND SEVERAL OTHER SNOWFALLS COMBINED TO PRODUCE THE
SNOWIEST JANUARY IN THE SHORT 20-YEAR HISTORY OF OBSERVATIONS AT THE
NATIONAL WEATHER SERVICE OFFICE IN GRAY. WHILE JANUARY WAS COLD,
FEBRUARY WAS DOWNRIGHT BRUTAL, FINISHING ALMOST 13 DEGREES BELOW
NORMAL AND BREAKING THE OLD RECORD FOR COLDEST FEBRUARY BY MORE THAN
7 DEGREES. IN FACT, FEBRUARY 2015 WAS THE COLDEST MONTH ON RECORD.

THE COLD CONTINUED INTO MARCH BUT THE SNOW FINALLY LET UP A BIT. THE
FIRST TRULY SPRING-LIKE TEMPERATURES DID NOT ARRIVE UNTIL APRIL 3RD
WHEN THE TEMPERATURE REACHED 65 DEGREES. THIS WAS JUST THE START OF
A CHANGE IN THE WEATHER PATTERN AS WARMER WEATHER GRADUALLY BEAT
BACK THE WINTER COLD. THE LAST SNOW OF THE SEASON FELL ON APRIL 8TH
AND 9TH WITH THE LAST OF THE WINTER SNOW PACK MELTING BY THE MORNING
OF APRIL 17TH. THE LAST FREEZE OF THE SEASON WAS ON APRIL 24TH. THE
WARMTH CONTINUED TO ACCELERATE INTO MAY AS TEMPERATURES BECAME
DOWNRIGHT SUMMER-LIKE THROUGH MUCH OF THE MONTH, WITH MANY DAYS
CLIMBING WELL INTO THE 80S. IT WAS THE WARMEST MAY ON RECORD AT
THE NATIONAL WEATHER SERVICE OFFICE IN GRAY.

A STORM SYSTEM BROUGHT 2.66 INCHES OF RAIN FROM MAY 31ST THROUGH
JUNE 2ND AND USHERED IN A CHANGE IN THE WEATHER PATTERN. AFTER THE
WARM AND DRY MAY, JUNE WAS COOL AND WET. ON JUNE 1ST AND 2ND THE
TEMPERATURE NEVER GOT OUT OF THE 40S, SOMETHING THAT HAD NEVER
HAPPENED BEFORE ON ANY DAY IN THE MONTH OF JUNE. WARMER WEATHER
BEGAN TO MAKE A COME BACK IN JULY AS PERIODS OF WARM WEATHER
INCREASINGLY BEGAN TO PUSH OUT THE COOLER TEMPERATURES. THE HOTTEST
TEMPERATURE OF THE YEAR OCCURRED ON JULY 12TH WHEN THE TEMPERATURE
REACHED 89 DEGREES. MORE PERSISTENT WARMTH ARRIVED AT THE END OF
JULY, WHEN 8 STRAIGHT DAYS SAW THE TEMPERATURE TOP 80 DEGREES FROM
JULY 28TH THROUGH AUGUST 4TH. THE WARM WEATHER CONTINUED TO WIN OUT
IN AUGUST AND SUMMER-LIKE WARMTH PERSISTED WELL INTO SEPTEMBER. THE
TEMPERATURE REACHED 89 DEGREES AGAIN ON SEPTEMBER 7TH AND THE
PERSISTENT WARMTH LED TO THE WARMEST SEPTEMBER ON RECORD.

A STORM SYSTEM BROUGHT VERY HEAVY RAINFALL AT THE END OF SEPTEMBER
WHEN 6.35 INCHES OF RAIN WAS MEASURED FROM THE 29TH INTO THE 30TH.
THIS RAINSTORM USHERED IN A CHANGE IN THE WEATHER PATTERN WITH MORE
FALL-LIKE WEATHER LASTING THROUGH OCTOBER. THE FIRST FREEZE OF THE
SEASON OCCURRED ON OCTOBER 18TH ALONG WITH THE FIRST SNOWFLAKES. A
RIDGE OF HIGH PRESSURE BEGAN ESTABLISHING ITSELF OVER THE EASTERN
UNITED STATES IN NOVEMBER, BRINGING PERSISTENT WARM WEATHER. THIS
PATTERN WAS ESPECIALLY NOTICEABLE IN DECEMBER WHEN FALL-LIKE WARMTH
KEPT THE WINTER COLD AT BAY. THE EARLY WINTER WARMTH CULMINATED IN A
HIGH TEMPERATURE OF 58 DEGREES ON CHRISTMAS DAY. THE FIRST
SIGNIFICANT SNOWFALL OF THE SEASON CAME A FEW DAYS LATER WHEN 5.2
INCHES OF SNOW AND SLEET FELL ON DECEMBER 29TH AND 30TH.

2015 MARKED THE SECOND STRAIGHT YEAR THAT THE TEMPERATURE DID NOT
REACH 90 DEGREES AT THE NATIONAL WEATHER SERVICE OFFICE IN GRAY. THE
LAST 90 DEGREE TEMPERATURE WAS ON SEPTEMBER 11, 2013. THE ONLY OTHER
YEAR ON RECORD THAT DID NOT REACH 90 DEGREES WAS 1996.
