THE YEAR BEGAN ON A WARM NOTE AS MANCHESTER WARMED TO 52 DEGREES.
AFTER LIGHT SNOW AND FREEZING RAIN ON JANUARY 8 AND 9, COLD AIR
POURED INTO THE AREA AND MUCH OF THE NEXT TWO WEEKS WAS SPENT BELOW
FREEZING. ANOTHER SNOWSTORM BROUGHT 6 INCHES OF SNOW ON JANUARY 19
AND 20 WITH EVEN COLDER AIR ARRIVING BEHIND IT. THE COLDEST DAY OF
THE YEAR WAS JANUARY 21 WHEN THE TEMPERATURE ONLY WARMED TO 5
DEGREES. THIS WAS QUICKLY FOLLOWED BY A JANUARY THAW A FEW DAYS
LATER. THE TEMPERATURE WARMED TO 56 DEGREES AND MORE THAN 1.5 INCHES
OF RAIN WASHED THE SNOW AWAY. MANCHESTER DIPPED DOWN TO ZERO DEGREES
AT THE END OF JANUARY AND BEGINNING OF FEBRUARY, BUT A FEW DAYS
LATER AN EVEN MORE DRAMATIC WARM UP OCCURRED. THE TEMPERATURE TOPPED
60 DEGREES ON FEBRUARY 4 AND 5. THIS TREND OF OSCILLATING
TEMPERATURE SWINGS CONTINUED THROUGH FEBRUARY, ALTHOUGH MANCHESTER
EVENTUALLY DEVELOPED A MORE PERSISTENT SNOW COVER. MORE SNOW AND
WINTER-LIKE COLD CONTINUED INTO MARCH, THOUGH EVENTUALLY WARMER
WEATHER FINALLY ARRIVED. THE LAST OF THE WINTER SNOW PACK MELTED BY
THE MORNING OF MARCH 16.
THE NEXT FEW MONTHS SAW FREQUENT CLOUDY AND SHOWERY WEATHER. IN
FACT, FROM APRIL THROUGH JUNE MANCHESTER SAW 47 DAYS WITH MEASURABLE
PRECIPITATION. THE CLOUDY, WET WEATHER MEANT MANY COOL DAYS AND WARM
NIGHTS. THE LAST FREEZE OF THE SEASON WAS ON APRIL 11. ALTHOUGH MOST
RAINY DAYS DID NOT SEE EXCESSIVE RAINFALL, THERE WERE A FEW HEAVIER
RAINFALLS INCLUDING APRIL 26 AND 27 (1.59 INCHES) AND JUNE 5 AND 6
(1.09 INCHES). A FEW PERIODS OF WARMER WEATHER WERE OBSERVED IN THE
MIDST OF THE OTHERWISE CLOUDY AND WET SPRING. SOME OF THE MORE
NOTABLE WARM DAYS WERE APRIL 13 (76), APRIL 19 (78), MAY 20 (83),
MAY 26 (87), AND JUNE 28 (91).
AFTER THE CLOUDY AND WET SPRING KEPT TEMPERATURES COOL, THE WEATHER
PATTERN SHIFTED AT THE END OF JUNE AND ESPECIALLY THROUGH THE MONTH
OF JULY. SUMMER HEAT ARRIVED IN THE FORM OF THREE HEAT WAVES. THE
FIRST BROUGHT 4 DAYS OF 90 DEGREE HEAT FROM JULY 3 THROUGH 6. THE
NEXT BROUGHT ANOTHER 3 DAYS OF 90 DEGREE HEAT FROM JULY 19 THROUGH
21. THE HOTTEST DAY OF THE YEAR WAS JULY 20 WHEN THE TEMPERATURE
REACHED 97 DEGREES. THE LOW THAT DAY WAS ONLY 80 DEGREES, A SIGN OF
THE HIGH HUMIDITY ACCOMPANYING THE HEAT. A COLD FRONT BROUGHT RAIN
AND COOLER TEMPERATURES A FEW DAYS LATER, BUT ONE MORE HEAT WAVE WAS
IN STORE BEFORE JULY WAS OVER. THE TEMPERATURE TOPPED 90 DEGREES
AGAIN FROM JULY 28 THROUGH 30. A SERIES OF COLD FRONTS BROUGHT SOME
RELIEF FROM THE HEAT IN AUGUST, BUT THERE WERE STILL SOME HOT DAYS
INCLUDING 92 DEGREES ON AUGUST 19. THE COLD FRONTS BROUGHT
PROGRESSIVELY COOLER AND DRIER AIR INTO THE REGION THROUGH MUCH OF
SEPTEMBER OFTEN BRINGING WARM DAYS AND COOL NIGHTS. ALTHOUGH THE
GRADUAL SHIFT TOWARD FALL WAS INEVITABLE, THERE WAS ONE MORE PERIOD
OF SUMMER-LIKE WARMTH. THE TEMPERATURE TOPPED 80 DEGREES FOR 4
STRAIGHT DAYS FROM SEPTEMBER 20 THROUGH 23, INCLUDING 89 DEGREES ON
SEPTEMBER 23. THE PERSISTENT FLOW OF DRY AIR OUT OF CANADA
CONTRIBUTED TO A LONG STRETCH OF DRY WEATHER IN LATE SUMMER AND
EARLY FALL.
IN OCTOBER A NEW WEATHER PATTERN BEGAN TO EMERGE FEATURING A TROUGH
OF LOW PRESSURE OVER THE CENTER OF THE COUNTRY WITH NEW ENGLAND ON
THE EASTERN SIDE OF THIS TROUGH. THIS MEANT WARM, MOIST AIR WAS
FUNNELED INTO THE AREA ALONG WITH MORE FREQUENT RAINFALL. SEVERAL
MORE SIGNIFICANT STORM SYSTEMS AFFECTED THE AREA IN LATE OCTOBER.
THE FIRST BROUGHT RAIN AND 49 MPH WINDS ON OCTOBER 17. THE LAST OF
THESE STORMS ARRIVED ON HALLOWEEN WITH WINDS GUSTING TO 45 MPH ON
NOVEMBER 1. THE FIRST FREEZE FINALLY OCCURRED ON NOVEMBER 2.
MUCH COLDER AIR BEGAN MOVING INTO THE AREA IN MID NOVEMBER. THE
TROUGH OVER THE CENTER OF THE COUNTRY SHIFTED EAST, ALLOWING VERY
COLD AIR TO POUR OUT OF CANADA INTO NEW ENGLAND. IT ALL BEGAN WITH A
COLD FRONT ON NOVEMBER 7. MUCH OF THE NEXT TWO WEEKS WAS 10 TO 15
DEGREES COLDER THAN NORMAL. THE COLDEST TEMPERATURE WAS 16 DEGREES
ON NOVEMBER 13, 14, AND 17. GRADUALLY THE COLD SPELL BROKE WITH SOME
WARMER WEATHER IN LATE NOVEMBER, INCLUDING MORE THAN AN INCH OF RAIN
ON NOVEMBER 24. HOWEVER, THE COLD WAS NOT TOO FAR AWAY AND IT
ARRIVED AGAIN IN DECEMBER. DECEMBER BEGAN WITH A LONG DURATION
SNOWSTORM WHICH BROUGHT 20.8 INCHES OF SNOW FROM DECEMBER 1 THROUGH
3. COLD CONTINUED FOR ABOUT A WEEK, WITH THE TEMPERATURE FALLING ALL
THE WAY TO 1 DEGREE ON DECEMBER 8. HOWEVER, WARMER AIR WOULD ARRIVE
THE VERY NEXT DAY AS THE TEMPERATURE SOARED ABOVE 50 DEGREES. THIS
WAS THE BEGINNING OF ABOUT A WEEK OF WARM WEATHER AND SIGNIFICANT
RAINFALL WHICH WOULD WASH AWAY ALL OF THE EARLY SEASON SNOWFALL. THE
HEAVIEST RAIN WAS ON DECEMBER 13 AND 14 WHEN 1.56 INCHES FELL. SOME
SNOW FELL A FEW DAYS LATER, BUT WARMER WEATHER JUST BEFORE CHRISTMAS
LEFT ONLY TRACES OF SNOW ON THE GROUND BY CHRISTMAS MORNING. THE
YEAR ENDED WITH ANOTHER LONG DURATION WINTER STORM WITH MANCHESTER
SEEING SNOW, SLEET, AND FREEZING RAIN ON DECEMBER 29 THROUGH 31.
THE AVERAGE TEMPERATURE FOR THE YEAR WAS 49.9 DEGREES WHICH WAS 0.7
DEGREES ABOVE NORMAL AND THE COOLEST YEAR SINCE 2015. THE
TEMPERATURE RANGED FROM ZERO DEGREES ON JANUARY 20, JANUARY 31, AND
FEBRUARY 2 TO 97 DEGREES ON JULY 20. THE FOLLOWING TABLE LISTS THE
AVERAGE TEMPERATURE FOR EACH MONTH OF 2019 INCLUDING DEPARTURES FROM
NORMAL.

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.
