...FALL SEASON CLIMATE NARRATIVE FOR NORTHERN AND EASTERN MAINE...

FALL 2017 FOR THE REGION WILL BE REMEMBERED AS ONE OF THE WARMEST ON
RECORD WITH NEAR TO JUST ABOVE AVERAGE PRECIPITATION.

TEMPERATURES FOR THE SEASON AVERAGED 4 TO 5 DEGREES ABOVE NORMAL AND
WAS THE WARMEST OF RECORD AT HOULTON AND NARROWLY FINISHED IN SECOND
PLACE AT CARIBOU AND MILLINOCKET TO THE FALL OF 2011 AND A LITTLE
MORE DISTANT SECOND PLACE AT BANGOR TO THE FALL OF 1931. IN FACT,
THE ONLY FACTOR THAT PREVENTED FALL OF 2017 FROM BEING THE WARMEST
OF RECORD FOR THE ENTIRE REGION WAS A SLIGHTLY BELOW AVERAGE
NOVEMBER, WHICH FOLLOWED THE WARMEST COMBINED SEPTEMBER-OCTOBER OF
RECORD.

PRECIPITATION FOR THE FALL SEASON RANGED FROM 90 TO 125 PERCENT OF
AVERAGE, AND WAS NOT EVENLY DISTRIBUTED WITH RELATIVELY LONG DRY
PERIODS BROKEN BY A FEW HEAVY RAIN EVENTS, LIKE THE THE VERY HEAVY
LATE OCTOBER RAIN EVENT WHICH FEATURED 3.50 TO 7.00 INCHES OF
RAINFALL FOR THE REGION. THIS EVENT WAS IMMEDIATELY FOLLOWED BY
INTENSE WIND AND RAIN EVENT WHICH RESULTED IN WIDESPREAD POWER
OUTAGES ESPECIALLY TO HANCOCK COUNTY.

LASTLY, DESPITE COLDER TEMPERATURES IN NOVEMBER, SNOWFALL WAS BELOW
AVERAGE ACROSS THE REGION, WITH SOME DOWNEAST AREAS NOT RECEIVING
ANY MEASURABLE SNOWFALL AND NORTHERN AREAS ONLY GETTING ABOUT 50
PERCENT OF AVERAGE. THE FIRST MEASURABLE SNOWFALL DAYS EVEN ACROSS
THE NORTH WERE AMONG THE LATEST OF RECORD, NOT UNTIL THE SECOND HALF
OF THE MONTH.
