AFTER SOME WARM WEATHER IN THE LAST HALF OF FEBRUARY, CONCORD SAW
ITS WINTER SNOW COVER RAPIDLY DWINDLING. AFTER THE FIRST WEEK OF
MARCH ONLY 1 INCH REMAINED. THIS MAY HAVE LED RESIDENTS TO EXPECT AN
EARLY SPRING, BUT THAT IS NOT WHAT WAS IN STORE. A NOR`EASTER
BROUGHT HEAVY SNOWFALL ON THE 7TH AND 8TH WHEN 11 INCHES OF SNOW WAS
MEASURED. SOME COLDER TEMPERATURES MOVED IN BEHIND THE STORM WITH A
REPLENISHED WINTER SNOW PACK RETURNING. ANOTHER POWERFUL NOR`EASTER
BROUGHT ANOTHER 17 INCHES OF SNOW ON THE 13TH AND 14TH, THIS TIME
ACCOMPANIED BY STRONG WINDS AS WELL. EVEN COLDER WEATHER MOVED IN
BEHIND THIS STORM, BRINGING WINTER-LIKE COLD IN THE MIDDLE OF MARCH.
THE WORST OF THE COLD BEGAN TO ABATE JUST AS ASTRONOMICAL SPRING
BEGAN, WITH THE REST OF THE MONTH SEEING GRADUALLY WARMING
TEMPERATURES AND A SLOW MELT OFF OF THE SECOND WINTER SNOW PACK. THE
LAST 4 DAYS OF MARCH SAW TEMPERATURES IN THE 50S, INCLUDING 58
DEGREES ON MARCH 29, SPRING-LIKE WARMTH WHICH HAD NOT BEEN SEEN
SINCE FEBRUARY.

THE AVERAGE TEMPERATURE FOR THE MONTH WAS 33.5 DEGREES WHICH WAS 0.4
DEGREES ABOVE NORMAL. ALTHOUGH DAYTIME HIGHS WERE COLDER THAN
NORMAL, NIGHTTIME LOWS WERE WARM ENOUGH TO BRING THE MONTHLY AVERAGE
ABOVE NORMAL. THE WARMEST MARCH ON RECORD WAS IN 2012 WHEN THE
AVERAGE TEMPERATURE WAS 41.1 DEGREES. THE COLDEST WAS IN 1885 WHEN
IT WAS 23.5 DEGREES.

A TOTAL OF 2.58 INCHES OF PRECIPITATION FELL WHICH WAS 0.69 INCHES
BELOW NORMAL. THE HEAVIEST PRECIPITATION FELL DURING THE SECOND
MAJOR SNOWSTORM WHEN 1.00 INCHES OF LIQUID EQUIVALENT PRECIPITATION
WAS RECORDED ON MARCH 13 AND 14. THE DRIEST MARCH ON RECORD WAS IN
1915 WHEN ONLY A TRACE OF PRECIPITATION WAS RECORDED. THE WETTEST
WAS IN 1936 WHEN 9.80 INCHES FELL.

THERE WAS 28.7 INCHES OF SNOWFALL WHICH WAS 17.6 INCHES ABOVE NORMAL
AND THE SNOWIEST MARCH SINCE 2001. THERE WERE TWO MAJOR SNOWSTORMS
WHICH EACH BROUGHT MORE THAN 10 INCHES OF SNOWFALL ON THE 7TH AND
8TH AND AGAIN ON THE 13TH AND 14TH. THE SNOWIEST MARCH ON RECORD WAS
IN 1956 WHEN 38.3 INCHES OF SNOW FELL. THE LEAST SNOWY WAS IN 1921
WHEN NO SNOW WAS OBSERVED. THERE HAVE BEEN 3 OTHER YEARS WHEN ONLY A
TRACE OF SNOW WAS OBSERVED IN MARCH, MOST RECENTLY IN 2010.

NO DAILY RECORDS WERE SET OR TIED IN MARCH 2018.
