UNSETTLED AND COOL CONDITIONS DOMINATED THE FIRST PART OF SEPTEMBER
WITH THE REMNANTS OF HURRICANE IDA BRINGING HEAVY RAIN ON THE 1ST
AND 2ND. TEMPERATURES THEN TRENDED ABOVE NORMAL THROUGH THE MIDDLE
TO LATTER PART OF THE MONTH AS WARMER AND HUMID AIRMASSES CROSSED
THE AREA WITH A COOL DOWN TO CLOSE OUT THE MONTH. AFTER 2.44 INCHES
OF RAIN FROM THE REMNANTS OF IDA THE REST OF SEPTEMBER WAS
CHARACTERIZED BY FREQUENT BOUTS OF LIGHT TO MODERATE RAIN WITHOUT
ANY EXTENDED PERIODS OF DRY WEATHER. OCTOBER WAS WARM IN THE
MANCHESTER AREA WITH THREE MULTI DAY STRETCHES OF TEMPERATURES
RISING INTO THE 70S. THE LONGEST STRETCH OCCURRED FROM THE 11TH TO
THE 16TH WITH SOME OF THESE DAYS WARMING INTO THE UPPER 70S. A
PERIOD OF WET WEATHER OCCURRED EARLY IN OCTOBER FOLLOWED BY AN
EXTENDED DRY PERIOD THROUGH THE MIDDLE OF THE MONTH. A MORE ACTIVE
PATTERN DEVELOPED DURING THE SECOND HALF OF THE MONTH WITH A STRONG
AREA OF LOW PRESSURE OVER SOUTHERN NEW ENGLAND BRINGING RAIN AND
STRONG NORTH TO NORTHEAST WINDS ON THE 26TH INTO THE 27TH. THE
HIGHEST WINDS GUST OCCURRED ON THE 27TH WHEN NORTH WIND GUSTS TOPPED
OUT AT 46 MPH. ANOTHER STRONG LOW PRESSURE SYSTEM PASSED JUST TO THE
EAST OF MANCHESTER BRINGING A SOAKING RAIN ON THE 30TH INTO THE
31ST. NOVEMBER WAS WARMER THAN NORMAL WITH BELOW NORMAL
PRECIPITATION. AFTER A STORMY END TO OCTOBER THE WEATHER PATTERN
TURNED QUIET OVER NEW ENGLAND FOR THE FIRST PART OF NOVEMBER.
PERSISTENT HIGH PRESSURE KEPT THE MANCHESTER AREA PRECIPITATION FREE
THROUGH THE FIRST WEEK AND A HALF WITH SOME MILD SUNNY DAYS AND COLD
CLEAR NIGHTS. THE FIRST FREEZE OF THE FALL SEASON OCCURRED ON
NOVEMBER 4TH WHEN THE LOW TEMPERATURE DROPPED TO 30 DEGREES. TOWARDS
THE END OF THE SECOND WEEK OF NOVEMBER THE PATTERN TURNED MORE
ACTIVE AS A BROAD AREA OF LOW PRESSURE TRACKED FROM THE GREAT LAKES
THROUGH THE NORTHEAST. THE PATTERN REMAINED RELATIVELY ACTIVE
THROUGH THE END OF NOVEMBER WITH FRONTAL PASSAGES BRINGING SEVERAL
TEMPERATURE SWINGS. AFTER A MILD THANKSGIVING, A COLD FRONT CROSSED
THE AREA WITH LOW PRESSURE DEVELOPING IN THE GULF OF MAINE LEADING
TO THE FIRST MEASURABLE SNOWFALL OF 0.1 INCH ON THE 26TH.
TEMPERATURES REMAINED BELOW AVERAGE TO CLOSE OUT THE MONTH WITH
ADDITIONAL TRACES OF SNOWFALL ON THE 27TH, 28TH, AND 29TH.
THE AVERAGE TEMPERATURE FOR THE FALL WAS 55.6 DEGREES, WHICH WAS 2.9
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 12.87 INCHES OF PRECIPITATION FELL, WHICH WAS 1.79 INCHES
ABOVE NORMAL. THIS INCLUDES THE 0.1 INCHES OF SNOW THAT FELL ON
NOVEMBER 26TH. THE HEAVIEST RAIN FELL ON SEPTEMBER 1ST AND 2ND WHEN
THE REMNANTS OF IDA BROUGHT 2.44 INCHES OF RAIN. THE WETTEST FALL
WAS IN 2018 WITH 19.45 INCHES. THE DRIEST WAS IN 1914 WITH ONLY 3.26
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.
