THE YEAR BEGAN WITH A COUPLE OF LIGHT SNOWFALLS WHICH HELPED
ESTABLISH A SOLID AND ENDURING SNOW COVER WHICH WOULD LAST FOR
SEVERAL MONTHS. AFTER MORE WINTRY PRECIPITATION ON JANUARY 8 AND 9,
VERY COLD ARCTIC AIR MOVED INTO THE REGION. MUCH OF THE NEXT TWO
WEEKS WAS SPENT BELOW FREEZING. THE COLDEST DAY WAS JANUARY 21 WHEN
THE TEMPERATURE DID NOT WARM ABOVE 5 DEGREES ALL DAY. DESPITE THE
VERY COLD WEATHER, THE JANUARY THAW WAS RIGHT AROUND THE CORNER. THE
TEMPERATURE WARMED TO 49 DEGREES ON JANUARY 24 WITH MORE THAN AN
INCH OF RAIN FALLING. THIS TREND OF OSCILLATING TEMPERATURE SWINGS
BETWEEN VERY MILD WEATHER AND VERY COLD ARCTIC AIR CONTINUED FOR
SEVERAL WEEKS. THE COLDEST TEMPERATURE WAS 3 BELOW ZERO ON JANUARY
31. ANOTHER THAW IN FEBRUARY SAW THE TEMPERATURE TOP 50 DEGREES FOR
TWO STRAIGHT DAYS INCLUDING 59 DEGREES ON FEBRUARY 5. THE BIGGEST
SNOWSTORM OF THE SEASON CAME ON FEBRUARY 12 AND 13 WHEN 9.0 INCHES
OF SNOW FELL. MORE LIGHT SNOW AND WINTER COLD CONTINUED INTO MARCH,
WITH THE SNOW DEPTH PEAKING AT 20 INCHES ON MARCH 11. GRADUALLY
WARMER SPRING-LIKE WEATHER AND SOME RAIN HELPED TO REDUCE THE SNOW
PACK, THOUGH IT TOOK UNTIL THE MORNING OF APRIL 18 FOR THE LAST OF
THE WINTER SNOW PACK TO MELT.

THE NEXT FEW MONTHS SAW FREQUENT CLOUDY AND SHOWERY WEATHER. IN
FACT, FROM APRIL TO JUNE THERE WERE 52 DAYS WITH MEASURABLE
PRECIPITATION. THIS WAS THE MOST ON RECORD; MORE THAN THE 50 WET
DAYS SEEN IN 2006. THE LAST FREEZE OF THE SEASON WAS ON APRIL 11,
ABOUT TWO WEEKS EARLIER THAN NORMAL. ALTHOUGH MOST RAINY DAYS DID
NOT SEE EXCESSIVE RAINFALL, THERE WERE A FEW HEAVIER RAINFALLS
INCLUDING APRIL 26 AND 27 (1.95 INCHES), MAY 28 AND 29 (0.96
INCHES), JUNE 11 (1.08 INCHES), AND JUNE 20 (1.52 INCHES). A FEW
BRIEF PERIODS OF WARMTH WERE OBSERVED IN THE MIDST OF THE OTHERWISE
CLOUDY AND WET SPRING. SOME OF THE MORE NOTABLE WARMER DAYS WERE
APRIL 13 (71), MAY 20 (75), AND JUNE 10 (80).

AFTER THE CLOUDY AND WET SPRING KEPT TEMPERATURES COOL, THE WEATHER
PATTERN SHIFTED IN LATE JUNE AND ESPECIALLY JULY. SUMMER HEAT
ARRIVED IN THREE WAVES DURING JULY. THE FIRST PEAKED AT 91 DEGREES
ON JULY 6. THE NEXT SAW 90 AND 91 DEGREES ON JULY 20 AND 21
RESPECTIVELY. AFTER A BRIEF COOL DOWN AND SOME RAIN, ONE FINAL HOT
SPELL CAME AT THE END OF JULY WITH TEMPERATURES IN THE UPPER 80S. A
SERIES OF COLD FRONTS BROUGHT SOME RELIEF FROM THE HEAT IN AUGUST,
THOUGH THERE WERE STILL PLENTY OF WARM 80 DEGREE DAYS. SOME OF THESE
FRONTS BROUGHT THUNDERSTORMS AND OCCASIONALLY HEAVIER RAINFALL. THE
PARADE OF COLD FRONTS CONTINUED THROUGH SEPTEMBER BRINGING
PROGRESSIVELY COOLER AND DRIER AIR OUT OF CANADA, BUT NOW WITH
LITTLE RAINFALL ACCOMPANYING THEM. THERE WAS ONE MORE WARM UP JUST
IN TIME FOR THE FALL EQUINOX AS THE TEMPERATURE TOPPED 80 DEGREES
FOR THREE STRAIGHT DAYS FROM SEPTEMBER 21 THROUGH 23.

A NEW WEATHER PATTERN BEGAN TO ESTABLISH ITSELF IN OCTOBER. IT
FEATURED A TROUGH OF LOW PRESSURE OVER THE CENTRAL UNITED STATES
WITH NEW ENGLAND ON THE EASTERN SIDE OF THIS TROUGH. THIS MEANT
WARM, MOIST AIR WAS FUNNELED INTO THE AREA ALONG WITH FREQUENT
RAINFALL. THE 19 DAYS OF MEASURABLE PRECIPITATION IN OCTOBER WAS THE
MOST ON RECORD AT GRAY. A SERIES OF MORE SIGNIFICANT STORM SYSTEMS
AFFECTED THE AREA IN THE LAST HALF OF OCTOBER. THE FIRST WAS ON
OCTOBER 17 WHEN MORE THAN AN INCH OF RAIN FELL ALONG WITH STRONG
WINDS. THE NEXT BROUGHT ALMOST 2 INCHES OF RAIN ON OCTOBER 22 AND
23, WITH ANOTHER INCH FALLING ON OCTOBER 27. THE LAST BEGAN ON
HALLOWEEN AND ENDED WITH MORE WINDY CONDITIONS ON NOVEMBER 1. THE
FIRST FREEZE OF THE SEASON FINALLY CAME ON NOVEMBER 2, MORE THAN TWO
WEEKS LATER THAN NORMAL.

THE TROUGH OVER THE MIDDLE OF THE COUNTRY SHIFTED EAST IN NOVEMBER,
ALLOWING VERY COLD ARCTIC AIR TO POUR INTO NEW ENGLAND. IT ALL BEGAN
WITH A COLD FRONT ON NOVEMBER 7, USHERING IN WINTER-LIKE COLD. THE
NEXT TWO WEEKS SAW TEMPERATURES 10 TO 20 DEGREES BELOW NORMAL ALONG
WITH SOME WINTRY PRECIPITATION. GRADUALLY THE TEMPERATURE BEGAN TO
MODERATE A BIT IN LATE NOVEMBER, WITH THE LAST FEW STORM SYSTEMS
WARM ENOUGH TO BRING MOSTLY RAIN. THAT CHANGED AS DECEMBER BEGAN
WITH A LONG DURATION SNOWSTORM AND MORE COLD WEATHER. THIS WASN`T TO
LAST, THOUGH, AS A WARM UP CAME IN THE SECOND WEEK OF DECEMBER. THE
TEMPERATURE TOPPED 50 DEGREES ON 4 DIFFERENT DAYS AND SIGNIFICANT
RAINFALL WASHED ALL THE EARLY SEASON SNOW AWAY. THE HEAVIEST RAIN
WAS ON DECEMBER 13 AND 14 WHEN 3.35 INCHES FELL. AFTER THIS STORM
MOVED AWAY THE COLD AIR RETURNED AND THE TEMPERATURE STAYED BELOW
FREEZING FOR THE NEXT 7 DAYS. SOME LIGHT SNOW ON DECEMBER 17 AND 18
MANAGED TO LAST THROUGH CHRISTMAS DESPITE SOME WARMTH RETURNING JUST
BEFORE THE HOLIDAY. THE YEAR ENDED WITH ANOTHER LONG DURATION WINTER
STORM AND GRAY PICKED UP 11.3 INCHES OF SNOW ON DECEMBER 30 AND 31,
THE BIGGEST SNOWSTORM OF 2019.

THE AVERAGE TEMPERATURE FOR THE YEAR WAS 45.5 DEGREES WHICH WAS 0.9
DEGREES BELOW NORMAL AND THE COOLEST YEAR SINCE 2014. THE COOLEST
YEAR WAS 1997 WITH AN AVERAGE TEMPERATURE OF 45.1 DEGREES. THE
