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. $$ KIMBLE
