...SEASONAL CLIMATE NARRATIVE FOR NORTHERN AND EASTERN MAINE...

FALL 2013 AVERAGED JUST A BIT ABOVE AVERAGE FOR TEMPERATURES AND
ABOVE AVERAGE FOR PRECIPITATION ACROSS NORTHEAST MAINE AND NEAR TO
A LITTLE BELOW NORMAL ACROSS THE REMAINDER OF THE REGION.

SEPTEMBER WILL MOSTLY BE REMEMBERED FOR THE CONTINUATION OF THE VERY
WET WEATHER WHICH BEGAN IN MID-MAY. CARIBOU AND BANGOR HAD THEIR
3RD AND 4TH WETTEST SEPTEMBERS ON RECORD RESPECTIVELY. THE WARMEST
WEATHER OF FALL OCCURRED ON SEPTEMBER 11TH WHEN MOST AREAS HAD
HIGHS IN THE LOWER TO MID 80S. THIS WAS FOLLOWED WITHIN 6 DAYS BY
THE COOLEST MORNING OF THE MONTH ON THE 17TH...WHEN MOST AREAS
INLAND FROM THE IMMEDIATE COAST DROPPED INTO THE 30S WITH SOME
FROST. ESTCOURT STATION AND HOULTON HAD A FREEZE WITH LOWS OF 27
AND 28 DEGREES RESPECTIVELY.

OCTOBER WAS MOSTLY A MILD AND DRY MONTH. OCTOBER GOT OFF TO A VERY
MILD START WITH WELL ABOVE NORMAL TEMPERATURES DURING THE FIRST TWO
THIRDS OF THE MONTH...WITH HIGH TEMPERATURES ON THE 1ST AND 2ND AS
WELL AS THE 10TH AND 11TH REACHING WELL INTO THE 70S NORTH OF THE
IMMEDIATE COAST.  SIGNIFICANT COOLING ARRIVED DURING THE LAST 10
DAYS OF THE MONTH.  THE FIRST MEASURABLE SNOWFALL OF THE SEASON
ARRIVED AT THE END OF THE MONTH WITH SNOWFALL OF A HALF AN INCH TO 3
INCHES ACROSS THE NORTHERN PORTION OF THE REGION ON THE 28TH.  THE
COLDEST TEMPERATURES OF THE MONTH WERE ALSO OBSERVED ON THE LAST TWO
MORNINGS OF THE MONTH WITH A LOW OF 15 DEGREES OBSERVED AT HOULTON
ON THE 30TH.  PRECIPITATION WAS WELL BELOW NORMAL IN MOST AREAS AND
THIS ENDED A STREAK OF ABOVE NORMAL PRECIPITATION MONTHS WHICH BEGAN
IN MAY.  AT BANGOR...ONLY 1.02 INCHES OF RAIN WAS OBSERVED...WHICH
MADE IT THE 3RD DRIEST OCTOBER ON RECORD.  ACROSS FAR NORTHERN MAINE
THE FALL FOLIAGE PEAKED AROUND THE 1ST OF THE MONTH AND FOR DOWNEAST
AREAS THE PEAK WAS NEAR THE 10TH OF THE MONTH.

NOVEMBER 2013 FINISHED WITH SLIGHTLY BELOW NORMAL TEMPERATURES AND
NEAR NORMAL PRECIPITATION. THE WARMEST WEATHER WAS OBSERVED ON THE
1ST WITH HIGHS IN THE 60S.  THE LOWEST TEMPERATURES OF THE MONTH
WERE OBSERVED ON THE LAST DAY OF THE MONTH.  THE FIRST BELOW ZERO
TEMPERATURE OF THE SEASON WAS OBSERVED AT ESTCOURT STATION AND BIG
BLACK RIVER ON THE MORNING OF THE 29TH WITH LOWS OF 7 BELOW AND 3
BELOW RESPECTIVELY.  THE MORNING OF THE 30TH WAS EVEN COLDER WITH A
LOW OF 10 BELOW AT BOTH OF THE ABOVE STATIONS.

PRECIPITATION WAS CLOSE TO NORMAL FOR THE MONTH. ACROSS THE NORTHERN
HALF OF THE AREA THERE WERE SEVERAL SMALL SNOW EVENTS FROM THE 10TH
THROUGH THE END OF THE MONTH.  THE BIGGEST EVENT OF THE FALL WAS A
STRONG STORM ON THE 27TH INTO THE 28TH THAT PRODUCED RAINFALL
AMOUNTS IN EXCESS OF 3 INCHES IN PARTS OF COASTAL HANCOCK AND
WASHINGTON COUNTIES AND FROM 1 TO 2.5 INCHES ACROSS MUCH OF THE
REMAINDER OF THE AREA. ACROSS FAR NORTHERN MAINE 1 TO 3 INCHES OF
SNOW ACCUMULATED BEFORE A RAPID CHANGEOVER TO THE SNOW ON THE
MORNING OF THE 27TH. WIND GUSTS FROM THIS STORM REACHED 40 TO 50 MPH
ACROSS MUCH OF THE REGION AND 50 TO 60 MPH NEAR THE COAST WITH A
PEAK GUST OF 64 MPH AT EASTPORT AND 69 MPH AT LUBEC IN WASHINGTON
COUNTY.

THE OUTLOOK FROM THE CLIMATE PREDICTION CENTER (CPC) FOR WINTER
2013-14 (DECEMBER THROUGH FEBRUARY) FOR NORTHERN AND EASTERN MAINE
CALLS FOR AN INCREASED CHANCE THAT THE 3-MONTH AVERAGE TEMPERATURE
WILL BE ABOVE NORMAL.  THIS IS DUE TO THE COMBINATION THAT THE
WINTERS OVER THE MOST RECENT DECADE HAVE BEEN ABOVE NORMAL AND SOME
LONG RANGE FORECASTING TOOLS THAT POINT TOWARD ABOVE NORMAL
TEMPERATURES.  THERE ARE NO STRONG CLIMATE SIGNALS THAT WOULD TILT
THE ODDS TOWARD AND UNUSUALLY WET (SNOWY) OR DRY WINTER.
