...OCTOBER 2024 CLIMATE NARRATIVE FOR NORTHERN/EASTERN MAINE...

OCTOBER 2024 WAS WARMER THAN NORMAL WITH MUCH BELOW AVERAGE
PRECIPITATION ACROSS THE REGION. TEMPERATURES RANGED FROM ABOUT 1.5
TO 3.5 DEGREES (F) ABOVE THE 1991-2020 NORMALS. PRECIPITATION WAS
GENERALLY BETWEEN 25 AND 50 PERCENT OF NORMAL.

IN CARIBOU, IT WAS THE 9TH WARMEST OCTOBER ON RECORD. SIX OF THE 10
WARMEST OCTOBERS IN CARIBOU HAVE OCCURRED SINCE 2007, INCLUDING FIVE
SINCE 2017. RECORDS IN CARIBOU DATE BACK TO 1939. ELSEWHERE,
TEMPERATURES FOR OCTOBER 2024 FELL OUTSIDE THE TOP 10 WARMEST ON
RECORD. THE WARMEST DAY OF OCTOBER CAME ON THE 31ST, WHEN ALL FOUR

TEMPERATURE OF 78 DEGREES, WHILE CARIBOU SAW A HIGH OF 77 DEGREES.
MILLINOCKET AND HOULTON REPORTED HIGH TEMPERATURES OF 75 AND 73
DEGREES, RESPECTIVELY. THE HIGH TEMPERATURES IN CARIBOU, BANGOR, AND
MILLINOCKET WERE THE WARMEST TEMPERATURES FOR SO LATE IN THE YEAR AT
THOSE SITES.

THE FIRST FREEZE OF THE YEAR OCCURRED ON OCTOBER 9TH IN CARIBOU,
WHICH WAS THE 6TH LATEST FIRST FREEZE DATE ON RECORD. OF THE TEN
LATEST FIRST FREEZE DATES ON RECORD IN CARIBOU, FIVE HAVE OCCURRED
SINCE 2010. THE FIRST FREEZE IN HOULTON OCCURRED ON OCTOBER 8TH,
WHICH IS THE 2ND LATEST ON RECORD. THE RECORD LATEST FIRST FREEZE IN

TEMPERATURE IN THE MONTH OF OCTOBER IN BANGOR SINCE 1944. THE ALL-
TIME LOWEST TEMPERATURE FOR THE MONTH OF OCTOBER IN BANGOR WAS 11
DEGREES, SET ON OCTOBER 30TH, 1941.

YET PERHAPS THE MOST NOTEWORTHY ASPECT OF OCTOBER 2024 WAS HOW DRY

ON RECORD. IT WAS ALSO THE 9TH DRIEST OCTOBER IN BANGOR. MEANWHILE,
MILLINOCKET AND HOULTON SAW THEIR 7TH AND 10TH DRIEST OCTOBERS ON

INCHES FOR OCTOBER 2024. AT THE START OF THE MONTH, THE US DROUGHT
MONITOR HAD MODERATE DROUGHT (D1) CONDITIONS ALONG THE DOWNEAST
COAST. ABNORMALLY DRY (D0) CONDITIONS WERE PRESENT IN MOST OF THE
REST OF THE AREA OUTSIDE OF THE SAINT JOHN VALLEY AND THE NORTH
WOODS. AT THE END OF THE MONTH, D1 CONDITIONS COVERED MOST LOCATIONS
SOUTH AND EAST OF KATAHDIN, AS WELL AS IN AROOSTOOK COUNTY ALONG THE
NEW BRUNSWICK BORDER. DO CONDITIONS COVERED MOST OF THE REST OF THE
AREA EXCEPT IN THE SAINT JOHN VALLEY AND TOWARDS THE QUEBEC BORDER.

THE FIRST SNOWFALL OF THE SEASON OCCURRED ON THE 14TH AND 15TH IN
THE NORTH WOODS, WHERE UP TO 2 INCHES OF SNOW FELL. ANOTHER MINOR
SNOW EVENT OCCURRED IN AROOSTOOK COUNTY ON THE 27TH, WHERE A TRACE
TO 1 INCH OF SNOW FELL. OFFICIALLY IN CARIBOU, 0.1 INCHES OF SNOW

PERCENT) OF ALL OCTOBERS ON RECORD. NO SNOW FELL DURING THE MONTH
SOUTH OF KATAHDIN. IN BANGOR, THE 1991-2020 AVERAGE OCTOBER SNOWFALL
IS 0.6 INCHES, AND MEASURABLE SNOW HAS FALLEN IN 10/94 (11 PERCENT)
OF ALL OCTOBERS, WITH 5 YEARS OF MISSING DATA.

FALL FOLIAGE PEAKED DURING THE FIRST WEEK OF THE MONTH ACROSS THE
NORTH, AND TOWARDS MID MONTH NEAR BANGOR AND DOWNEAST. A STRONG WIND
EVENT OCCURRED ON THE 12TH, WITH WIND GUSTS OVER 50 MPH. SINCE THE
TREES IN CENTRAL AND SOUTHERN AREAS STILL HAD LEAVES ON THEM,
NUMEROUS TREES AND POWERLINES WERE TAKEN DOWN. OVER 100 THOUSAND
CUSTOMERS WERE LEFT WITHOUT POWER, WITH THE LARGEST OUTAGES
OCCURRING IN PISCATAQUIS, PENOBSCOT, AND HANCOCK COUNTIES.

THE CLIMATE PREDICITION CENTER`S (CPC) OUTLOOK FOR NOVEMBER 2024
INDICATES THAT THE ODDS ARE TILTED TOWARDS ABOVE NORMAL
TEMPERATURES. THE CPC SHOWS THE ODDS SLIGHTLY TILTED TOWARDS
UNUSUALLY DRY CONDITIONS FOR DOWNEAST MAINE. ELSEWHERE, THERE ARE NO
STRONG CLIMATE SIGNALS THAT POINT TOWARDS UNUSUALLY WET (SNOWY) OR
UNUSUALLY DRY CONDITIONS IN NOVEMBER 2024. AVERAGE HIGH TEMPERATURES
RANGE FROM THE MID 40S TO LOWER 50S (FROM NORTH TO SOUTH) AT THE
START OF THE MONTH. BY THE END OF THE MONTH, AVERAGE HIGHS RANGE
FROM THE UPPER 30S TO THE MID 40S. AVERAGE LOW TEMPERATURES RANGE
FROM NEAR 40 DEGREES AT THE START OF THE MONTH DOWNEAST, TO THE LOW
TO MID 20S BY THE END OF THE MONTH. ACROSS THE FAR NORTH, AVERAGE
LOWS DROP FROM THE LOWER 30S AT THE START OF THE MONTH TO THE UPPER
TEENS BY THE END OF THE MONTH.

AND 4.00 INCHES ACROSS THE REGION. SNOWFALL IN CARIBOU FOR NOVEMBER
AVERAGES 10.4 INCHES, WHILE IN BANGOR SNOWFALL AVERAGES 4.3 INCHES.

FREQUENCY OF LARGER SNOW EVENTS INCREASES MOST RAPIDLY DURING THE
2ND HALF OF THE MONTH. NEARLY 2 HOURS OF DAYLIGHT IS LOST DURING
