METEOROLOGICAL WINTER BEGAN WARM AND WET WITH MORE THAN 1 INCH OF
RAINFALL ON DECEMBER 1. AN ACTIVE WEATHER PATTERN BEGAN TO BRING A
NEW STORM SYSTEM INTO THE REGION EVERY FEW DAYS, WITH EACH ONE
BRINGING SOME SNOW AND COLDER TEMPERATURES. BY THE MIDDLE OF
DECEMBER, A BRUTALLY COLD EARLY SEASON ARCTIC AIR MASS WAS IN PLACE.
DECEMBER 16 WAS THE COLDEST DECEMBER DAY ON RECORD IN THE SHORT 21-
YEAR HISTORY OF OBSERVATIONS AT THE NATIONAL WEATHER SERVICE IN
GRAY. THE LOW TEMPERATURE OF -6 DEGREES TIED THE COLDEST DECEMBER
TEMPERATURE ON RECORD, AND THE HIGH OF 4 DEGREES WAS THE COLDEST
DECEMBER HIGH TEMPERATURE ON RECORD. THE BRUTAL COLD EASED UP ON
DECEMBER 21 WITH SOME EVEN WARMER AIR MOVING IN AFTER CHRISTMAS. AN
INTENSIFYING STORM SYSTEM ON DECEMBER 29 BROUGHT MORE THAN 16 INCHES
OF SNOW ON THE 29TH AND 30TH, WITH MOST OF THAT FALLING IN JUST A
FEW HOURS. ANOTHER BRIEF COLD SNAP CAME IN EARLY JANUARY, BUT IT DID
NOT LAST LONG. THE TEMPERATURE WARMED ALL THE WAY TO 50 DEGREES ON
JANUARY 11 WITH GENERALLY WARM WEATHER LASTING THROUGH THE BEGINNING
OF FEBRUARY. THE WEATHER PATTERN SHIFTED AGAIN FOR THE SECOND WEEK
OF FEBRUARY. A COLD AND VERY SNOWY PATTERN SET UP, WITH SNOW

INCHES OF SNOW WAS OBSERVED ON 5 OF THOSE DAYS WITH THE TOTAL FOR
THE PERIOD SURPASSING 43 INCHES. THE DEPTH OF SNOW ON THE GROUND
PEAKED AT 34 INCHES ON FEBRUARY 16 AND 17, THE GREATEST WINTER SNOW
DEPTH ON RECORD. JUST TWO DAYS LATER THE TEMPERATURE WARMED ALL THE
WAY TO 57 DEGREES ON THE 19TH, THE WARMEST FEBRUARY TEMPERATURE ON
RECORD. THIS SIGNALED A CHANGE BACK TO A WARMER WEATHER PATTERN
WHICH LASTED THROUGH THE END OF FEBRUARY. THERE WERE ANOTHER 3
STRAIGHT DAYS ABOVE 50 DEGREES FROM FEBRUARY 22 THROUGH 24.

THE AVERAGE TEMPERATURE FOR THE WINTER SEASON WAS 26.8 DEGREES WHICH
WAS 2.5 DEGREES ABOVE NORMAL THE WARMEST WINTER WAS IN 2001-02 WHEN

THERE WAS 88.5 INCHES OF SNOWFALL THIS WINTER WHICH WAS 32.5 INCHES
ABOVE NORMAL AND THE SNOWIEST WINTER SINCE 2007-08. ABOUT HALF OF
THE WINTER SNOWFALL FELL DURING A PARTICULARLY SNOWY STRETCH IN MID

16.6 INCHES OF SNOW FELL THAT EVENING INTO THE EARLY MORNING HOURS.
