THE FALL BEGAN WITH A SERIES OF COOL, DRY AIR MASSES MOVING OUT OF
CANADA. THIS BROUGHT MANY COOL DAYS AND EVEN COOLER NIGHTS. THE
COLDEST TEMPERATURE OF THIS STRETCH WAS 33 DEGREES ON SEPTEMBER 19.
BUT JUST AS THE COOL WEATHER REACHED ITS MINIMUM, WARM, SUMMER-LIKE
WEATHER MADE A COME BACK. HOT WEATHER BUILDING OVER THE SOUTHEAST US
SPILLED INTO NEW ENGLAND AND CONCORD TOPPED 80 DEGREES FOR THE NEXT
4 STRAIGHT DAYS. AFTER THIS LATE SEASON WARM UP, THE TREND OF COOL,
DRY, CANADIAN AIR MASSES RETURNED FOR THE NEXT FEW WEEKS. THE
COLDEST TEMPERATURE OF THIS STRETCH WAS 27 DEGREES ON OCTOBER 5 AN
6, THE FIRST FREEZE OF THE SEASON. SOON THE WEATHER PATTERN BEGAN TO
CHANGE AGAIN. A TROUGH OF LOW PRESSURE DEVELOPED OVER THE CENTER OF
THE COUNTRY, WITH NEW ENGLAND ON THE EASTERN SIDE OF THIS TROUGH.
THIS ALLOWED WARM AND VERY MOIST AIR TO MOVE INTO THE AREA ALONG
WITH SEVERAL LOW PRESSURE SYSTEMS DELIVERING MORE FREQUENT RAINFALL.
THE MOISTURE AND FREQUENT CLOUDS HAD THE EFFECT OF BRINGING MANY
COOL DAYS AND WARM NIGHTS. A FEW MORE INTENSE STORM SYSTEMS BROUGHT
SIGNIFICANT WEATHER TO THE AREA BEGINNING IN LATE OCTOBER. THE FIRST
WAS ON OCTOBER 16 AND 17 WHEN MORE THAN 2 INCHES OF RAIN FELL AND
WINDS GUSTED TO 49 MPH LEADING TO SCATTERED WIND DAMAGE. AT LEAST
THREE MORE STORMS FOLLOWED IN THE NEXT TWO WEEKS, WITH THE LAST
ARRIVING ON HALLOWEEN, OCTOBER 31. WINDS BEHIND THIS STORM ON
NOVEMBER 1 GUSTED TO 45 MPH JUST AS CONCORD SAW ITS LAST 70 DEGREE
TEMPERATURE OF THE SEASON. SOON COLDER AIR WOULD ARRIVE. THE MORE
INTENSE COLD ARRIVED ON NOVEMBER 7 AND LASTED FOR NEARLY TWO WEEKS.
MOST DAYS WERE 10 TO 15 DEGREES BELOW NORMAL. THE FIRST ACCUMULATING
SNOW OF THE SEASON FELL ON NOVEMBER 12 WITH THE TEMPERATURE NOT
WARMING ABOVE FREEZING AGAIN FOR THE NEXT TWO DAYS. THE COLDEST
TEMPERATURE WAS ON NOVEMBER 17 WHEN THE TEMPERATURE REACHED 7
DEGREES. GRADUALLY THE TEMPERATURE DRIFTED BACK TOWARD NORMAL WITH
THE LAST FEW STORM SYSTEMS IN NOVEMBER BRINGING MOSTLY RAIN.

THE AVERAGE TEMPERATURE FOR THE FALL WAS 48.0 DEGREES WHICH WAS 0.8
DEGREES BELOW NORMAL AND THE COOLEST FALL SINCE 1997. THE COOLEST
FALL WAS IN 1972 WHEN THE AVERAGE TEMPERATURE WAS 43.7 DEGREES. THE
WARMEST WAS 53.5 DEGREES IN 2017.

A TOTAL OF 9.81 INCHES OF PRECIPITATION FELL WHICH WAS 1.33 INCHES
BELOW NORMAL. THE HEAVIEST PRECIPITATION FELL ON OCTOBER 16 AND 17
WHEN 2.29 INCHES OF RAIN WAS MEASURED. THE DRIEST FALL WAS IN 1908
WHEN ONLY 2.88 INCHES WAS RECORDED. THE WETTEST WAS IN 2005 WITH
22.08 INCHES.

THERE WAS 0.3 INCHES OF SNOWFALL WHICH WAS 2.3 INCHES BELOW NORMAL.
ALL OF THIS SNOW FELL ON NOVEMBER 12. SNOWFALL IN THE FALL IS
VARIABLE AND ALMOST ALWAYS FALLS IN THE LAST PART OF NOVEMBER AS THE
SNOW SEASON IS JUST BEGINNING. THE SNOWIEST FALL WAS IN 2011 WHEN
25.7 INCHES WAS MEASURED. THERE HAVE BEEN 3 FALLS WITH NO SNOWFALL,
MOST RECENTLY IN 2015. AN ADDITIONAL 29 YEARS HAD ONLY A TRACE OF
SNOWFALL IN THE FALL, MOST RECENTLY IN 2010.
