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 1.77 INCHES
OF RAIN FROM THE REMNANTS OF IDA THE REST OF SEPTEMBER WAS
CHARACTERIZED BY FREQUENT BOUTS OF LIGHT TO MODERATE RAIN. OCTOBER
ON THE WHOLE WAS WARM AND RELATIVELY DRY FOR MUCH OF THE MONTH. THE
CONCORD AREA EXPERIENCED MULTIPLE WARM SPELLS THROUGHOUT OCTOBER
WHERE THE HIGH TEMPERATURE ROSE ABOVE 70 DEGREES WITH THE LONGEST
STRETCH OF 70 DEGREES OR HIGHER OCCURRING FROM THE 11TH TO THE 16TH.
PRECIPITATION EVENTS WERE RELATIVELY SPARSE THROUGH THE FIRST HALF
OF THE MONTH WITH A GENERAL SHIFT TO AN ACTIVE PATTERN THE SECOND
HALF OF THE MONTH. OCTOBER RAINFALL WOULD HAVE ENDED UP WELL BELOW
NORMAL IF NOT FOR AN AREA OF LOW PRESSURE BRINGING MODERATE TO HEAVY
RAIN ON THE 30TH INTO THE 31ST. THIS SYSTEM BROUGHT THE GREATEST
RAINFALL DURING THE FALL WITH A TOTAL OF 2.25 INCHES RECORDED. IN
ADDITION TO SEVERAL DAYS WARMING INTO THE 70S, OVERNIGHT LOWS WERE
ALSO ABOVE NORMAL WITH CONCORD RECORDING ITS SECOND LATEST FREEZE ON
RECORD WHEN THE TEMPERATURES DROPPED TO 27 DEGREES ON THE 24TH. THIS
WAS ONE DAY SHORT OF THE LATEST FREEZE ON RECORD, WHICH WAS OCTOBER
25, 1921 WHEN THE TEMPERATURE DROPPED TO 30 DEGREES. AFTER A STORMY
END TO OCTOBER THE WEATHER PATTERN OVER NEW ENGLAND TURNED QUIET
THROUGH THE FIRST PART OF NOVEMBER. PERSISTENT HIGH PRESSURE KEPT
THE CONCORD AREA PRECIPITATION FREE THROUGH THE FIRST WEEK AND A
HALF WITH SOME MILD SUNNY DAYS AND COLD CLEAR NIGHTS. 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 THE MONTH 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 0.4 INCHES ON THE 26TH.

THE AVERAGE TEMPERATURE WAS 52.1 DEGREES, WHICH WAS 2.3 DEGREES
ABOVE NORMAL AND TIES WITH 2016 AND 1879 FOR THE SEVENTH WARMEST
FALL ON RECORD. THE WARMEST FALL ON RECORD WAS 53.5 DEGREES IN 2017.
THE COOLEST WAS 43.7 DEGREES IN 1972. THE FOLLOWING TABLE LISTS THE
WARMEST FALLS ON RECORD AT CONCORD.
