THE PERSISTENT LATE-FEBRUARY WARMTH CONTINUED INTO THE FIRST FEW
DAYS OF MARCH AND THE TEMPERATURE REACHED AS HIGH AS 64 DEGREES ON
MARCH 1. IF RESIDENTS BELIEVED THIS WAS A SIGN OF A WARM SPRING,
THEY WERE SOON DEEPLY DISAPPOINTED. MUCH COLDER AIR BEGAN MOVING
INTO NEW ENGLAND ON MARCH 3 AND ROUND AFTER ROUND OF ARCTIC AIR
POURED IN THROUGH MOST OF THE MONTH. ALTHOUGH THERE WERE OCCASIONAL
LIGHT SNOWFALLS, THE BIGGEST SNOWFALL BY FAR WAS ON MARCH 14 WHEN A
NOR`EASTER BROUGHT MORE THAN 15 INCHES OF SNOW AND BLIZZARD
CONDITIONS. COLD WEATHER CONTINUED FOR A FEW MORE WEEKS, THOUGH
TEMPERATURES DID SLOWLY WARM BACK UP CLOSER TO NORMAL BY THE END OF
THE MONTH. ONE MORE SNOWSTORM BEGAN ON MARCH 31 AND BY MIDNIGHT
NEARLY 6 INCHES HAD FALLEN.

THE AVERAGE TEMPERATURE FOR THE MONTH WAS 29.1 DEGREES WHICH WAS 4.0
DEGREES BELOW NORMAL. THE COLDEST MARCH WAS IN 1885 WHEN THE AVERAGE
TEMPERATURE WAS 23.5 DEGREES. THE WARMEST WAS IN 2012 AT 42.1
DEGREES.

A TOTAL OF 3.98 INCHES OF PRECIPITATION FELL WHICH WAS 0.71 INCHES
ABOVE NORMAL. THE HEAVIEST PRECIPITATION FELL ON THE 14TH WHEN 1.56
INCHES OF LIQUID EQUIVALENT SNOWFALL. THE WETTEST MARCH WAS IN 1938
WHEN 9.80 INCHES FELL. THE DRIEST WAS IN 1915 WHEN ONLY A TRACE OF
PRECIPITATION WAS RECORDED.

A TOTAL OF 22.4 INCHES OF SNOW FELL WHICH WAS 11.3 INCHES ABOVE
NORMAL AND THE MOST MARCH SNOWFALL SINCE 2001. MOST OF THAT SNOW
FELL ON MARCH 14TH WHEN MORE THAN 15 INCHES WAS MEASURED. THE
SNOWIEST MARCH WAS IN 1956 WHEN 38.3 INCHES FELL. NO SNOW FELL IN
1921. THERE HAVE BEEN 3 ADDITIONAL YEARS WHICH ONLY RECORDED A TRACE
OF SNOWFALL, MOST RECENTLY IN 2010.
