DROUGHT WHICH BEGAN IN SPRING CONTINUED THROUGH SEPTEMBER. A SERIES
OF HIGH PRESSURE CENTERS BROUGHT DRY CONTINENTAL AIR MASSES INTO THE
REGION FOR THE FIRST 4 WEEKS OF FALL. COOL HIGH PRESSURE REMAINED
STATIONARY OVER THE AREA FOR SEVERAL DAYS IN MID SEPTEMBER LEADING
TO COOL DAYS AND EVEN COOLER NIGHTS. THE TEMPERATURE DIPPED INTO THE
30S FOR 3 STRAIGHT DAYS BEFORE 80 DEGREE WARMTH RETURNED FOR THE
LAST WEEK OF THE MONTH. SOME RAIN FINALLY ARRIVED ON SEPTEMBER 30
WITH JUST UNDER HALF AN INCH FALLING. A SERIES OF FRONTS BROUGHT
ALTERNATING WARMER AND COOLER CONDITIONS AS THE STORM TRACK
GRADUALLY SHIFTED TOWARD THE REGION IN OCTOBER. THE FIRST
SIGNIFICANT STORM SYSTEM BROUGHT MORE THAN AN INCH OF RAIN ON
OCTOBER 13. ANOTHER INCH OF RAIN FELL ON OCTOBER 16 AND 17.
CONDITIONS TURNED COOLER IN THE LAST PART OF OCTOBER WITH THE FIRST
SNOWFALL OF THE SEASON COMING JUST BEFORE HALLOWEEN. THE COOL
WEATHER LASTED A COUPLE OF WEEKS BEFORE MANCHESTER SAW ONE OF ITS
MOST INTENSE AND LONG LASTING LATE SEASON WARM SPELLS. BEGINNING ON
NOVEMBER 5 THE TEMPERATURE TOPPED 70 DEGREES FOR 7 STRAIGHT DAYS. A
COLD FRONT ON NOVEMBER 12 BROUGHT THIS STRETCH OF UNUSUALLY WARM
WEATHER TO AN END WITH MORE FREQUENT STORMINESS RETURNING. THE
HEAVIEST RAIN FELL ON NOVEMBER 23 WHEN MORE THAN AN INCH AND A HALF
WAS RECORDED. ANOTHER STORM BROUGHT MORE THAN AN INCH ON NOVEMBER 30
ALONG WITH 41 MPH WINDS.

THE AVERAGE TEMPERATURE FOR THE FALL WAS 54.4 DEGREES WHICH WAS 2.8
DEGREES ABOVE NORMAL. THE WARMEST FALL WAS IN 2017 WHEN THE AVERAGE
TEMPERATURE WAS 55.7 DEGREES. THE COOLEST WAS 46.9 DEGREES IN 1936.

A TOTAL OF 9.75 INCHES OF PRECIPITATION FELL WHICH WAS 2.29 INCHES
BELOW NORMAL. THIS INCLUDES THE 2.5 INCHES OF SNOW WHICH FELL ON
OCTOBER 30. THE HEAVIEST PRECIPITATION FELL ON NOVEMBER 23 WITH 1.66
INCHES RECORDED. THE DRIEST FALL WAS IN 1914 WHEN ONLY 3.26 INCHES
WAS RECORDED. THE WETTEST WAS IN 2018 WITH 19.45 INCHES.

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.
