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 42 DEGREES ON SEPTEMBER 19
AND 20. BUT JUST AS THE COLD REACHED ITS PEAK INTENSITY, HOT WEATHER
BUILDING OVER THE SOUTHEAST US SPILLED INTO NEW ENGLAND BRINGING
MORE SUMMER-LIKE WEATHER. THE NEXT 4 DAYS SAW THE TEMPERATURE WARM
INTO THE 80S WITH THE WARMEST TEMPERATURE COMING ON SEPTEMBER 23 AT
89 DEGREES. AFTER THIS THE SERIES OF COOLER, DRY AIR MASSES RETURNED
FOR THE NEXT FEW WEEKS. THE TEMPERATURE BOTTOMED OUT AT 34 DEGREES
ON OCTOBER 6. SOON THE WEATHER PATTERN BEGAN TO SHIFT AS A LARGE
TROUGH OF LOW PRESSURE DEVELOPED OVER THE CENTER OF THE COUNTRY WITH
NEW ENGLAND ON THE EASTERN SIDE OF THIS TROUGH. THIS ALLOWED WARM,
MOIST AIR TO MOVE INTO THE REGION ALONG WITH MORE FREQUENT RAINFALL.
THE CLOUDS AND RAIN OFTEN BROUGHT COOL DAYS AND WARM NIGHTS. A
SERIES OF STORM SYSTEMS AFFECTED THE AREA BEGINNING IN LATE OCTOBER.
THE FIRST WAS ON OCTOBER 16 AND 17 WHEN NEARLY 1.5 INCHES OF RAIN
FELL ALONG WITH 49 MPH WINDS THAT CAUSED SCATTERED WIND DAMAGE. AT
LEAST 3 MORE STORMS FOLLOWED IN THE NEXT TWO WEEKS, WITH THE LAST
ARRIVING ON HALLOWEEN, OCTOBER 31. AS THIS STORM DEPARTED ON
NOVEMBER 1 IT BROUGHT 45 MPH WINDS ALONG WITH THE LAST WARM DAY OF
THE SEASON AT 73 DEGREES. THE FIRST FREEZE OF THE SEASON CAME THE
VERY NEXT DAY. MORE INTENSE COLD ARRIVED ON NOVEMBER 7 WITH MUCH OF
THE NEXT TWO WEEKS SEEING TEMPERATURES 10 TO 15 DEGREES BELOW
NORMAL. ALTHOUGH LIGHT SNOW WAS OBSERVED ON SEVERAL DAYS,
ACCUMULATIONS WERE NOT NOTED. THE COLDEST TEMPERATURE WAS 16 DEGREES
ON NOVEMBER 13, 14, AND 17. GRADUALLY THE TEMPERATURE DRIFTED BACK
TOWARD NORMAL WITH THE LAST FEW STORM SYSTEMS BRINGING MOSTLY RAIN.

THE AVERAGE TEMPERATURE WAS 51.9 DEGREES WHICH WAS 0.3 DEGREES ABOVE
NORMAL. THE COOLEST FALL WAS IN 1951 WHEN THE AVERAGE TEMPERATURE
WAS 49.6 DEGREES. THE WARMEST WAS 55.7 DEGREES IN 2017.

A TOTAL OF 5.76 INCHES OF PRECIPITATION FELL WHICH WAS 6.28 INCHES
BELOW NORMAL AND THE SECOND DRIEST FALL ON RECORD. THE DRIEST FALL
WAS IN 2001 WHEN ONLY 5.15 INCHES FELL. THE WETTEST WAS JUST LAST
YEAR WHEN 19.45 INCHES FELL IN 2018. ONLY TRACES OF SNOWFALL WERE
OBSERVED THIS FALL.

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.
