WINTER 2015-16 WAS THE WARMEST AND ONE OF THE LEAST SNOWY ON RECORD
AT CONCORD. BEGINNING IN THE LATE FALL OF 2015, A STAGNANT JET
STREAM PATTERN KEPT COOL TEMPERATURES IN THE WESTERN UNITED STATES
AND WARM TEMPERATURES IN THE EAST. THIS WARMTH CONTINUED TO BUILD
THROUGH THE MONTH OF DECEMBER, PEAKING WITH A HIGH TEMPERATURE OF 62
DEGREES ON CHRISTMAS DAY. EVERY DAY FROM DECEMBER 2 THROUGH 28 WAS
ABOVE NORMAL, LEADING TO THE WARMEST DECEMBER ON RECORD. COLDER AIR
FINALLY ARRIVED AFTER CHRISTMAS ALONG WITH THE FIRST SNOW OF THE
SEASON ON DECEMBER 29, THE SECOND LATEST START OF THE SNOW SEASON ON
RECORD. JANUARY FEATURED A FEW PERIODS OF COLD AND LIGHT SNOW ALONG
WITH MORE PERIODS OF WARM WEATHER. THE WARMTH BEGAN TO BUILD AGAIN
BY THE END OF JANUARY AND THE BEGINNING OF FEBRUARY, BUT A SNOWSTORM
ON FEBRUARY 5 SIGNALED A CHANGE IN THE WEATHER PATTERN.
PROGRESSIVELY COLDER AIR BEGAN ARRIVING OVER THE FOLLOWING WITH, AND
BY MID FEBRUARY A BRUTALLY COLD ARCTIC AIR MASS WAS IN PLACE. THE
TEMPERATURE DROPPED BELOW ZERO FOR 4 STRAIGHT DAYS, BOTTOMING OUT AT
13 BELOW ZERO ON FEBRUARY 13. BUT THE COLD WOULD NOT LAST MUCH
LONGER. ANOTHER STORM SYSTEM BROUGHT LIGHT SNOW CHANGING TO RAIN AS
THE TEMPERATURE WARMED INTO THE 50S. WARM WEATHER DOMINATED THE LAST
HALF OF FEBRUARY AND WHAT WAS LEFT OF THE MEAGER WINTER SNOW PACK
MELTED DOWN TO JUST A TRACE BY THE END OF THE MONTH.

THE AVERAGE TEMPERATURE WAS 30.9 DEGREES WHICH WAS 7.0 DEGREES ABOVE
NORMAL AND THE WARMEST WINTER ON RECORD. UNTIL THIS YEAR THE WARMEST
WINTER WAS 1879-80 WHEN THE AVERAGE TEMPERATURE WAS 30.4 DEGREES.
THE COLDEST WAS 1917-18 AT ONLY 15.5 DEGREES. THE FOLLOWING TABLE
