...NORTHERN AND EASTERN MAINE MONTHLY AREA CLIMATE NARRATIVE...

MARCH 2015 FEATURED WELL BELOW NORMAL TEMPERATURES AND BELOW NORMAL
LIQUID PRECIPITATION. TEMPERATURES RANGED FROM 4 TO 6 DEGREES BELOW
NORMAL. SNOWFALL WAS MORE VARIABLE ACROSS THE REGION WITH THE
LARGEST DEPARTURES FROM NORMAL ACROSS FAR EASTERN MAINE.

AT CARIBOU...THE AVERAGE TEMPERATURE OF 19.5 DEGREES WAS 5 DEGREES
BELOW THE 1981-2010 NORMALS. IT TIED WITH 1989 AS THE 11TH COLDEST
MARCH ON RECORD. THERE WERE A TOTAL OF 18 DAYS WHEN THE HIGH
TEMPERATURE DID NOT RISE ABOVE FREEZING...WHICH COMPARES TO AN
AVERAGE OF 12. ON THE MORNING OF THE 6TH THE LOW TEMPERATURE OF 20
BELOW TIED THE RECORD LOW FOR THE DATE WHICH WAS FIRST ESTABLISHED
IN 1948.

AT BANGOR...THE AVERAGE TEMPERATURE OF 24.3 DEGREES WAS 5.9 DEGREES
BELOW NORMAL. IT RANKED AS THE 4TH COLDEST MARCH BEHIND ONLY
2014...1967...AND 1939. THERE WERE A TOTAL OF 10 DAYS WHEN THE HIGH
TEMPERATURE FAILED TO RISE ABOVE FREEZING...WHICH COMPARES TO AN
AVERAGE OF 6. THREE RECORD LOWS WERE SET DURING THE MONTH. ON THE
MORNING OF THE 1ST...THE LOW OF 14 BELOW ESTABLISHED A NEW DAILY
TEMPERATURE RECORD. THE OLD RECORD OF 11 BELOW WAS ESTABLISHED IN
2001. ON THE 6TH...THE LOW OF 14 BELOW BROKE THE PREVIOUS RECORD OF
12 BELOW SET IN 1948. FINALLY...ON THE 24TH THE LOW OF 4 DEGREES
TIED THE PREVIOUS RECORD LOW WHICH WAS ESTABLISHED JUST LAST YEAR.

MARCH 2015 FEATURED BELOW NORMAL LIQUID PRECIPITATION ACROSS
NORTHERN AND EASTERN MAINE THAT AVERAGED BETWEEN 40 AND 75 PERCENT
OF NORMAL. SNOWFALL WAS MORE VARIABLE AND RANGED FROM ABOVE NORMAL
ACROSS EASTERN AROOSTOOK...WASHINGTON...AND PARTS OF WESTERN
PISCATAQUIS COUNTIES TO BELOW NORMAL ACROSS THE REMAINDER OF THE
REGION.

THE BIG STORY THIS PAST MARCH WAS THE COLD. THE PERSISTENCE OF THE
COLD WEATHER DURING THE MONTH WAS REMARKABLE. THERE WERE ONLY 5 DAYS
IN MOST AREAS WITH ABOVE AVERAGE TEMPERATURES DURING THE ENTIRE
MONTH.

THE MONTH BEGAN WITH A SNOWPACK OF ONLY AROUND A FOOT IN PARTS OF
THE SAINT JOHN VALLEY WITH 15 TO 25 INCHES ACROSS MUCH OF THE
REMAINDER OF FAR NORTHERN MAINE. DOWN EAST AMOUNTS RANGED FROM 30 TO
50 INCHES...WITH UNOFFICAL AMOUNTS AS MUCH AS HIGH AS 60 INCHES IN
PARTS OF COASTAL HANCOCK AND COASTAL WASHINGTON COUNTIES. BY THE END
OF THE MONTH...THE SNOWPACK WAS STILL AROUND A FOOT FROM CARIBOU
NORTH THROUGH THE ST JOHN VALLEY AND FROM 1 TO 2 FEET ACROSS MOST OF
CENTRAL AND DOWN EAST MAINE...WITH LOCALLY HIGHER AMOUNTS IN PARTS
OF WASHINGTON COUNTY.

THE OUTLOOK FROM THE CLIMATE PREDICATION CENTER
HTTP://WWW.CPC.NCEP.NOAA.GOV/ FOR APRIL INDICATES AN INCREASED
LIKELIHOOD OF BELOW NORMAL TEMPERATURES. THERE ARE SOME LONG RANGE
INDICATIONS THAT THE PERSISTENT COLD MAY BREAK AT SOME POINT DURING
THE 2ND HALF OF THE MONTH. THERE ARE NO STRONG CLIMATE SIGNALS THAT
WOULD POINT TOWARD A WET OR SNOWY MONTH OR AN UNUSUALLY DRY MONTH.
AVERAGE TEMPERATURES RISE RAPIDLY IN APRIL WITH THE INCREASING SUN
ANGLE AND DAY LENGTH. THE AVERAGE HIGH AT CARIBOU RISES FROM 40F ON
THE 1ST TO 56F ON THE 30TH. THE AVERAGE LOW TEMPERATURE RISES FROM
23F ON THE 1ST TO 36F BY MONTHS END. AT BANGOR...THE AVERAGE HIGH
CLIMBS FROM 46F AT THE START OF THE MONTH TO 59F ON THE 30TH. THE
AVERAGE LOW RISES FROM 27F AT THE START OF THE MONTH TO 37F BY
MONTHS END. DAYLIGHT INCREASES RAPIDLY WITH OVER AN HOUR AND A HALF
INCREASE IN AVAILABLE DAYLIGHT DURING THE MONTH OF APRIL.
