WINTER GOT OFF TO A MILD START WITH TEMPERATURES AVERAGING WELL
ABOVE NORMAL THROUGH THE FIRST HALF OF DECEMBER THANKS TO SEVERAL
DAYS WITH HIGH TEMPERATURES INTO THE 50S AND A COUPLE OF NIGHTS WHERE
THE LOW TEMPERATURE DID NOT DROP BELOW FREEZING. THIS MILD START TO
WINTER CAN BE ATTRIBUTED TO A PERSISTENT RIDGE OF HIGH PRESSURE OVER
THE SOUTHEAST US THAT OFTEN EXTENDED INTO NEW ENGLAND. THIS RIDGE OF
HIGH PRESSURE OFTEN FORMS OVER THE SOUTHEAST US DURING LA NINA
WINTERS WITH THIS PAST WINTER FEATURING MODERATE LA NINA CONDITIONS
IN THE TROPICAL PACIFIC. THE MILD WEATHER PATTERN TURNED MORE WINTRY
AFTER A STRONG COLD FRONT CROSSED THE AREA ON DECEMBER 17TH. ON
DECEMBER 18TH TO 19TH LOW PRESSURE TRACKED ACROSS SOUTHERN NEW
ENGLAND BRINGING THE FIRST APPRECIABLE SNOWFALL OF THE SEASON WITH
4.6 INCHES OF SNOWFALL. TEMPERATURES THEN STAYED NEAR OR BELOW
NORMAL PRESERVING THE SNOWPACK INTO CHRISTMAS DAY. ANOTHER AREA OF
LOW PRESSURE CROSSED THE AREA CHRISTMAS WEEKEND BRINGING A TOTAL OF
3.7 INCHES OF SNOW BY THE 26TH. TEMPERATURES THEN TRENDED ABOVE
NORMAL THROUGH THE END OF THE YEAR INTO THE FIRST COUPLE OF DAYS OF
JANUARY. THROUGH THE MIDDLE OF JANUARY TEMPERATURES OSCILLATED
BETWEEN BELOW NORMAL AND ABOVE NORMAL AS THE WEATHER PATTERN ACROSS
NORTH AMERICA STARTED TO UNDERGO A TRANSITION. THIS TRANSITION WAS
RELATED TO THE PACIFIC NORTH AMERICAN PATTERN SHIFTING TO ITS
POSITIVE PHASE AFTER BEING IN ITS NEGATIVE PHASE DURING DECEMBER
INTO EARLY JANUARY. THIS SHIFT TO A +PNA LED TO A PERSISTENT RIDGE
OF HIGH PRESSURE ACROSS WESTERN NORTH AMERICA WITH A DEEP TROUGH
OVER THE EASTERN CONUS THROUGH THE END OF JANUARY. THE TROUGH OVER
THE EASTERN CONUS BROUGHT A PERIOD OF PERSISTENT COLD DURING THE
SECOND HALF OF JANUARY ALLOWING TEMPERATURES TO AVERAGE BELOW NORMAL
FOR THE MONTH OF JANUARY. THIS TROUGH ALSO PRODUCED A POWERFUL OCEAN
STORM THAT BROUGHT BLIZZARD CONDITIONS TO THE GRAY AREA ON JANUARY
29TH. TOTAL SNOWFALL FROM THIS STORM WAS 8.1 INCHES AND WAS THE
GREATEST SNOWFALL OF THE WINTER SEASON. GOING INTO FEBRUARY THE
RIDGE OVER THE SOUTHEAST US REDEVELOPED AND REMAINED A DOMINANT
FEATURE THROUGH THE END OF WINTER. MILD SOUTHWEST FLOW AROUND THE
RIDGE BROUGHT SEVERAL WARM SPELLS TO THE GRAY AREA IN FEBRUARY. THE
WARMEST PERIOD CAME ON FEBRUARY 23RD WHEN THE HIGH REACHED 63
DEGREES, WHICH WAS THE WARMEST DAY OF THE WINTER SEASON. ANOTHER
DOMINANT FEATURE ON THE NORTH AMERICAN WEATHER MAP DURING FEBRUARY
WAS A PERSISTENT TROUGH OVER CENTRAL CANADA. AS NORTHERN NEW ENGLAND
WAS POSITIONED BETWEEN THIS TROUGH AND A RIDGE OVER THE SOUTHEAST US
THE STORM TRACK HAD A TENDENCY TO CUT ACROSS THE AREA WITH SYSTEMS
BRINGING A VARIETY OF PRECIPITATION TYPES IN FEBRUARY. THE MOST
SIGNIFICANT PRECIPITATION EVENT OF THE WINTER OCCURRED ON FEBRUARY
3RD TO 4TH WHEN WAVES OF LOW PRESSURE TRACKED ALONG A COLD FRONT
THAT SLOWLY SANK SOUTH THROUGH NEW ENGLAND AND THEN STALLED NEAR THE
LATITUDE OF GRAY. THIS SET UP LED TO A PERIOD OF RAIN THAT THEN
CHANGED OVER TO SLEET AND EVENTUALLY ENDED AS SNOW WITH A LIQUID
EQUIVALENT STORM TOTAL OF 1.96 INCHES. SYSTEMS THAT THEN CROSSED THE
AREA THROUGH THE MIDDLE OF FEBRUARY WERE PRIMARILY RAIN PRODUCERS
WHICH BROUGHT THE SNOWPACK DOWN TO 2 INCHES AFTER A PEAK OF 12
INCHES AT THE END OF JANUARY. AN AREA OF LOW PRESSURE FINALLY TOOK A
MORE SOUTHERLY TRACK FEBRUARY 25TH BRINGING 5.1 INCHES OF SNOW WITH
COLD WEATHER PERSISTING THROUGH THE END OF FEBRUARY.

THE AVERAGE TEMPERATURE FOR WINTER WAS 24.6 DEGREES, WHICH WAS 0.4
DEGREES BELOW NORMAL. THE COLDEST WINTER WAS IN 2014-15 WHEN THE
AVERAGE TEMPERATURE WAS 19.8 DEGREES. THE WARMEST WAS IN 2001-02
WHEN THE AVERAGE TEMPERATURE WAS 29.8 DEGREES.

A TOTAL OF 9.28 INCHES OF PRECIPITATION FELL, WHICH WAS 2.20 INCHES
BELOW NORMAL. THE HEAVIEST PRECIPITATION FELL FEBRUARY 3RD AND 4TH
WHEN A LIQUID EQUIVALENT OF 1.96 INCHES WAS MEASURED. THE DRIEST
WINTER WAS IN 2006-07 WHEN ONLY 7.17 INCHES WAS RECORDED. THE
WETTEST WAS IN 2007-08 WITH 15.31 INCHES.

THERE WAS 37.8 INCHES OF SNOWFALL, WHICH WAS 20.9 INCHES BELOW
NORMAL. THE HEAVIEST SNOW FELL ON JANUARY 29TH WHEN 8.1 INCHES
WAS MEASURED. THE LEAST SNOWY WINTER WAS IN 1997-98 WHEN ONLY
26.5 INCHES WAS RECORDED. THE SNOWIEST WINTER WAS IN 2007-08
WITH 111.3 INCHES.
