AFTER A VERY COLD NOVEMBER, METEOROLOGICAL WINTER BEGAN WITH A LONG
DURATION SNOWSTORM. IT BEGAN ON DECEMBER 1 AND DIDN`T END UNTIL
DECEMBER 3. A TOTAL OF 20.8 INCHES WAS MEASURED FROM THIS STORM WITH
COLD WEATHER CONTINUING FOR THE FIRST WEEK OF DECEMBER. SOON THE
WEATHER PATTERN BEGAN TO SHIFT AND MUCH WARMER AIR MOVED INTO THE
REGION. THE TEMPERATURE TOPPED 50 DEGREES ON DECEMBER 9 AND 10 WITH
RAIN FALLING. MORE RAIN AND 50 DEGREE WARMTH CAME ON DECEMBER 13 AND
14 WHEN MORE THAN 1.5 INCHES OF RAIN WASHED THE REST OF THE EARLY
SEASON SNOW AWAY. MORE LIGHT SNOW FELL ON DECEMBER 17, BUT A RETURN
TO WARM WEATHER LEFT ONLY A TRACE ON THE GROUND BY CHRISTMAS
MORNING. ANOTHER LONG DURATION WINTER STORM BROUGHT SNOW, SLEET, AND
FREEZING RAIN JUST BEFORE NEW YEARS. A NEW WEATHER PATTERN WAS
BEGINNING TO EMERGE THAT FEATURED PERSISTENT MILD WEATHER WITH BRIEF
PERIODS OF ARCTIC COLD. THE NEXT STRETCH OF WARM WEATHER PEAKED AT
69 DEGREES ON JANUARY 12. MID JANUARY SAW A FEW MORE SNOWSTORMS WITH
COLDER AIR MOVING IN AS WELL. IT DIDN`T LAST LONG, THOUGH, AS
MANCHESTER SAW ABOUT TWO WEEKS OF WARMER THAN NORMAL TEMPERATURES AT
THE END OF JANUARY AND BEGINNING OF FEBRUARY WHICH MELTED THE SNOW
PACK. A WINTER STORM BROUGHT SNOW, SLEET, AND FREEZING RAIN ON
JANUARY 6 AND 7 FOLLOWED BY COLDER TEMPERATURES. ANOTHER SNOWSTORM
ON FEBRUARY 13 BROUGHT EVEN COLDER AIR IN BEHIND IT. THE COLDEST
TEMPERATURE WAS 7 BELOW ZERO ON FEBRUARY 15, THE COLDEST TEMPERATURE
IN MORE THAN TWO YEARS (SINCE JANUARY 2, 2018). THE VERY NEXT DAY IT
WARMED UP BACK INTO THE 40S AGAIN WITH THE WARM WEATHER LASTING MOST
OF THE REST OF FEBRUARY, MELTING THE SNOW PACK ONCE AGAIN. THE
WARMEST TEMPERATURE OF THIS STRETCH WAS 60 DEGREES ON FEBRUARY 24.

THE AVERAGE TEMPERATURE FOR THE WINTER WAS 31.2 DEGREES WHICH WAS
3.6 DEGREES ABOVE NORMAL. THE WARMEST WINTER WAS IN 2015-16 WHEN THE
AVERAGE TEMPERATURE WAS 33.7 DEGREES. THE COLDEST WAS 19.3 DEGREES
IN 1947-48.

A TOTAL OF 10.25 INCHES OF PRECIPITATION FELL WHICH WAS 1.17 INCHES
ABOVE NORMAL. THIS INCLUDES 39.5 INCHES OF SNOW AND SLEET. THE
HEAVIEST PRECIPITATION WAS IN DECEMBER WHEN THREE MAJOR STORMS
AFFECTED THE AREA. THE FIRST DROPPED 1.46 INCHES MOSTLY IN THE FORM
OF SNOW ON DECEMBER 1 THROUGH 3. THE NEXT BROUGHT 1.56 INCHES OF
RAIN ON DECEMBER 13 AND 14. THE LAST BROUGHT 1.19 INCHES OF SNOW,
SLEET, FREEZING RAIN, AND RAIN ON DECEMBER 29 THROUGH 31. THE
WETTEST DECEMBER WAS IN 1886-87 WHEN 15.41 INCHES FELL. THE DRIEST
WAS IN 1930-31 WHEN ONLY 5.56 INCHES WAS RECORDED.

HISTORICAL RECORDS AT MANCHESTER BEGAN IN 1885, BUT WITHIN THIS
RECORD THERE REMAIN NUMEROUS YEARS OF UNAVAILABLE DATA. DUE TO THIS,
HISTORICAL RECORDS SHOULD BE CONSIDERED INCOMPLETE AS SOME
SIGNIFICANT EXTREMES MAY BE MISSING FROM THE DATA. MORE CONSISTENT
MODERN RECORDS BEGAN IN 1998 AND CONTINUE TO THE PRESENT.
