A COLD FRONT CROSSED NEW ENGLAND TO START THE FALL SEASON FOLLOWED
BY A FEW DAYS OF HIGH PRESSURE THAT BROUGHT WARM AND SUNNY DAYS AND
COOL NIGHTS. ANOTHER COLD FRONT TRACKED INTO NEW ENGLAND AND STALLED
OVER THE AREA WITH SEVERAL WAVES OF LOW PRESSURE TRACKING ALONG THE
FRONT BRINGING PERIODS OF MODERATE TO HEAVY RAIN. THIS WAS THEN
FOLLOWED BY A DRIER STRETCH OF WEATHER FOR THE SECOND WEEK OF
SEPTEMBER. ADDITIONAL FRONTAL SYSTEMS CROSSED THE MANCHESTER AREA
THROUGH THE SECOND HALF OF SEPTEMBER WITH THE HEAVIEST RAIN OF THE
FALL SEASON OCCURRING ON SEPTEMBER 22ND WHEN THUNDERSTORMS BROUGHT
2.21 INCHES OF RAIN. ANOTHER FEATURE OF INTEREST DURING SEPTEMBER
WAS TROPICAL STORM FIONA PASSING WELL OFFSHORE ON SEPTEMBER 23RD AND
24TH BRINGING HIGH SURF CONDITIONS TO AREA BEACHES. DURING OCTOBER A
RIDGE IN THE JET STREAM DEVELOPED OVER THE WEST COAST OF NORTH
AMERICA WITH A TROUGH OF LOW PRESSURE OVER THE GREAT LAKES AND
ANOTHER RIDGE NEAR NEWFOUNDLAND. THIS JET STREAM CONFIGURATION LED
TO SEVERAL FRONTAL SYSTEMS TRACKING FROM THE OHIO VALLEY ACROSS NEW
ENGLAND BRINGING PERIODS OF RAIN AND MULTIPLE TEMPERATURE SWINGS.
ALTHOUGH THIS WAS A RELATIVELY ACTIVE PATTERN, THE MANCHESTER AREA
WAS OFTEN TOO FAR WEST OF THE AXIS OF HEAVIEST PRECIPITATION. THERE
WAS A PRONOUNCED PATTERN CHANGE AT THE END OF OCTOBER THROUGH EARLY
NOVEMBER WHEN A TROUGH OF LOW PRESSURE DEVELOPED ALONG THE WEST
COAST OF NORTH AMERICA AND A RIDGE OF HIGH PRESSURE FORMED OVER NEW
ENGLAND. THIS LEAD TO MOSTLY DRY CONDITIONS AND EXCEPTIONAL WARMTH
THROUGH THE FIRST WEEK AND A HALF OF NOVEMBER. DURING THE FIRST 12
DAYS OF NOVEMBER THE AVERAGE TEMPERATURE WAS 56.5 DEGREES AND WAS
THE WARMEST 12 DAY STRETCH DURING NOVEMBER ON RECORD BEATING THE
PREVIOUS WARMEST 12 DAYS BY 3.5 DEGREES, WHICH OCCURRED FROM
NOVEMBER 5TH THROUGH 16TH BACK IN 2020. ALSO DURING THIS STRETCH THE
HIGH TEMPERATURE EXCEEDED THE 70 DEGREE MARK SEVEN TIMES, AND A NEW
ALL TIME RECORD HIGH FOR THE MONTH OF NOVEMBER OCCURRED ON THE 5TH
WHEN THE HIGH TEMPERATURE REACHED 79 DEGREES. THE RIDGE OVER NEW
ENGLAND BROKE DOWN DURING THE MIDDLE OF NOVEMBER WITH THE DOMINANT
PATTERN THROUGH THE END OF FALL CONSISTING OF A RIDGE OF HIGH
PRESSURE OVER WESTERN CANADA AND TROUGH OF LOW PRESSURE OVER NEW
ENGLAND. THIS PATTERN ALLOWED FOR A COUPLE OF FRONTAL SYSTEMS TO
CROSS NEW ENGLAND, BRINGING MAINLY BOUTS OF RAIN ALTHOUGH MANCHESTER
DID SEE A FEW DAYS WITH A TRACE OF SNOWFALL. ADDITIONALLY, THE
TROUGH OF LOW PRESSURE OVER NEW ENGLAND ALLOWED TEMPERATURES TO
TREND BELOW NORMAL THROUGH THE SECOND HALF OF NOVEMBER.
THE AVERAGE TEMPERATURE FOR FALL WAS 54.0 DEGREES, WHICH WAS 1.3
DEGREES ABOVE NORMAL. THE WARMEST FALL ON RECORD WAS IN 2017 WHEN
THE AVERAGE TEMPERATURE WAS 55.7 DEGREES. THE COOLEST WAS 46.9
DEGREES IN 1936.
A TOTAL OF 12.72 INCHES OF PRECIPITATION FELL, WHICH WAS 1.64 INCHES
ABOVE NORMAL. THE HEAVIEST PRECIPITATION FELL FROM THUNDERSTORMS ON
SEPTEMBER 22ND WHEN 2.21 INCHES OF RAIN FELL. THE WETTEST FALL ON
RECORD WAS IN 2018 WHEN 19.45 INCHES OF PRECIPITATION FELL. THE
DRIEST WAS 3.26 INCHES IN 1914. NO MEASURABLE SNOWFALL WAS RECORDED
IN MANCHESTER, ALTHOUGH A TRACE OF SNOW WAS RECORDED EACH DAY FROM
NOVEMBER 15TH TO NOVEMBER 18TH.
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.
