FALL 2018 STARTED WELL ABOVE NORMAL BUT ENDED WELL BELOW NORMAL
MAKING FOR A MORE ABRUPT TRANSITION FROM SUMMER TO WINTER THAN
USUAL. IT STARTED WITH A RIDGE OF HIGH PRESSURE THAT REMAINED OVER
THE EAST COAST AND WESTERN ATLANTIC THROUGH SEPTEMBER AND INTO THE
FIRST PART OF OCTOBER. THIS PULLED WARM, HUMID AIR UP AND AROUND
THIS RIDGE AND INTO NEW ENGLAND. THE HOTTEST WEATHER WAS IN THE
FIRST WEEK OF SEPTEMBER WHEN MANCHESTER ENDURED 4 STRAIGHT DAYS AT
90 DEGREES OR WARMER FROM SEPTEMBER 3 TO 6. OCCASIONAL COLD FRONTS
WOULD BRING BRIEF BREAKS OF COOLER WEATHER, BUT THE WARM AND HUMID
KEPT RETURNING. HURRICANE FLORENCE MADE LANDFALL IN NORTH CAROLINA,
BUT ITS REMNANTS EVENTUALLY MADE THEIR WAY AROUND THE RIDGE AND INTO
THE AREA, DROPPING MORE THAN 3 INCHES OF RAIN ON SEPTEMBER 18. WARM
AND HUMID CONDITIONS REMAINED THE RULE INTO THE FIRST PART OF
OCTOBER WHEN MANCHESTER TOPPED 80 DEGREES AGAIN ON OCTOBER 9 AND 10.
THIS WAS THE LAST OF THE WARMTH, THOUGH, AS THE PATTERN FINALLY
SHIFTED AND MUCH COOLER WEATHER ARRIVED. THE FIRST FREEZE OF THE
SEASON CAME ON OCTOBER 18. A TROUGH DEVELOPED OVER THE EASTERN
UNITED STATES AND BROUGHT SEVERAL ROUNDS OF COLD WEATHER. BEING ON
THE EASTERN SIDE OF THE TROUGH MEANT THAT MOST OF THE STORMS
CROSSING THE COUNTRY WOULD EXIT THROUGH NEW ENGLAND BRINGING NEW
PRECIPITATION EVERY FEW DAYS RIGHT THROUGH NOVEMBER. A COLD FRONT ON
NOVEMBER 13 SENT THE TEMPERATURE TUMBLING TO NEW LOWS. IT DIDN`T
EVEN WARM ABOVE FREEZING ON NOVEMBER 15 AS THE FIRST SNOWSTORM OF
THE SEASON BEGAN. THIS STORM BROUGHT MORE THAN 8 INCHES OF SNOW TO
THE CITY. ANOTHER SNOWSTORM ARRIVED ON NOVEMBER 20 AND EVEN COLDER
AIR POURED IN BEHIND IT JUST IN TIME FOR THANKSGIVING. AFTER FALLING
TO 9 DEGREES THANKSGIVING MORNING, NOVEMBER 22, THE TEMPERATURE ONLY
ROSE TO 18 THAT AFTERNOON, COLD EVEN BY JANUARY STANDARDS! THE
TEMPERATURE BEGAN TO MODERATE BACK TOWARD NORMAL BY THE END OF THE
MONTH WITH SNOW CHANGING TO RAIN AND THE EARLY SEASON SNOW COVER
MELTING AWAY.

THE AVERAGE TEMPERATURE FOR THE SEASON WAS 51.3 DEGREES WHICH WAS
0.3 DEGREES BELOW NORMAL. IT RANGED FROM 94 DEGREES ON SEPTEMBER 3
TO 9 DEGREES ON NOVEMBER 22. A TOTAL OF 18.61 INCHES OF
PRECIPITATION FELL WHICH WAS 6.57 INCHES ABOVE NORMAL. THE HEAVIEST
RAIN WAS ON SEPTEMBER 18 WHEN 3.86 INCHES FELL. A TOTAL OF 13.1
INCHES OF SNOW FELL WITH THE HEAVIEST OCCURRING ON THE 15TH AND 16TH
WHEN 8.2 INCHES WAS MEASURED.

HISTORICAL RECORDS AT MANCHESTER ARE NOT PROVIDED DUE TO NUMEROUS
MISSING YEARS WITHIN THE HISTORICAL RECORD. ALTHOUGH THE EARLIEST
DATA AVAILABLE IS IN 1885, THERE ARE SIGNIFICANT GAPS IN THE DATA. A
LOCAL STUDY HAS YET TO BE COMPLETED TO DETERMINE IF MEANINGFUL
INFORMATION ON EXTREME TEMPERATURE, PRECIPITATION, OR SNOWFALL CAN
BE REPORTED.
