AFTER COLD WEATHER HAD LASTED MUCH OF NOVEMBER, THIS COLD BEGAN TO
EASE UP A BIT AS THE CALENDAR CHANGED TO DECEMBER. THE FIRST WEEK
SAW TEMPERATURES WARMING INTO THE 40S AND EVEN THE 50S. BUT THIS
BRIEF BREAK FROM THE COLD WAS NOT GOING TO LAST. THE FIRST
SIGNIFICANT SNOWSTORM OF THE SEASON ARRIVED ON DECEMBER 9 BRINGING A
SHIFT TOWARD COLDER WEATHER. COLDER TEMPERATURES SOON BECAME THE NEW
NORMAL WITH THE NEXT SEVERAL STORM SYSTEMS BRINGING SNOW AND/OR
FREEZING RAIN. THE NEXT SIGNIFICANT SNOWSTORM ARRIVED CHRISTMAS
MORNING WITH BRUTALLY COLD ARCTIC AIR POURING IN BEHIND THIS STORM
AND LASTING WELL INTO THE NEW YEAR. THE NEXT 15 DAYS DID NOT WARM
ABOVE FREEZING. THIS WAS ONE OF THE MOST BRUTAL COLD SPELLS ON
RECORD AT AUGUSTA. FOR 6 STRAIGHT DAYS, FROM DEC 28 THRU JAN 2, THE
TEMPERATURE WOULD NOT EVEN WARM TO 10 DEGREES, TYING THE RECORD SET
IN 1979. TEMPERATURES FELL BELOW ZERO EACH NIGHT, WITH THE LOW OF 15
BELOW ZERO ON DECEMBER 29TH TYING AS THE COLDEST TEMPERATURE EVER
OBSERVED IN THE MONTH OF DECEMBER. THERE WAS A BRIEF BREAK IN THE
BRUTAL COLD WHEN THE TEMPERATURE WARMED ALL THE WAY INTO THE MID
20S, BUT THIS "BREAK" WAS ACCOMPANIED BY ANOTHER STRONG NOR`EAST
THAT BROUGHT BLIZZARD CONDITIONS AND 51 MPH WINDS ON JANUARY 4. MORE
BRUTAL COLD AIR POURED IN BEHIND THIS STORM WITH 3 MORE NIGHTS WITH
SUBZERO TEMPERATURES. IN FACT, THE TEMPERATURE DID NOT EVEN WARM
ABOVE ZERO AT ALL ON JANUARY 6, THE COLDEST HIGH TEMPERATURE SINCE
2004. FINALLY THE INTENSE COLD BEGAN TO BREAK AND THE TEMPERATURE
ROSE ABOVE FREEZING AGAIN FOR THE FIRST TIME ON JANUARY 9, JUST AS
THE JANUARY THAW BEGAN. THE NEXT 4 DAYS BROUGHT WARMING
TEMPERATURES. THE TEMPERATURE PEAKED AT 53 DEGREES ON THE 12TH AND
13TH AS WARM AIR AND HEAVY RAINFALL SURGED NORTHWARD AHEAD OF A
STRONG COLD FRONT. THIS WARM WEATHER AND RAINFALL WASHED FLUSHED
EXTRA WATER THROUGH AN ICE PACKED KENNEBEC RIVER, LEADING TO ICE JAM
FLOODING. THE STRONG COLD FRONT BROUGHT A RETURN TO VERY COLD
WEATHER FOR A FEW DAYS, THOUGH THIS COLD SPELL WAS NOT AS INTENSE OR
AS LONG LASTING AS THE LAST ONE. MORE SNOW FELL ON JANUARY 17TH AND
FREEZING RAIN BROUGHT ICING ON THE 23RD, BUT FOR THE NEXT FEW WEEKS
THE TEMPERATURE WAS GRADUALLY WARMING AGAIN. SOME COLDER AIR
RETURNED AT THE END OF JANUARY INTO THE BEGINNING OF FEBRUARY. THE
COLDEST TEMPERATURE FROM THIS COLDER SPELL WAS 1 DEGREE ON FEBRUARY
3. ULTIMATELY THIS PROVED TO BE THE LAST SIGNIFICANT COLD SPELL OF
THE WINTER. MUCH OF FEBRUARY SAW WARMING TEMPERATURES WITH PERIODIC
LIGHTER SNOWFALLS. THE GRADUAL WARMING INTENSIFIED IN THE LAST PART
OF THE MONTH AS A RIDGE OF HIGH PRESSURE BROUGHT WARM AIR FROM THE
SOUTHERN UNITED STATES INTO NEW ENGLAND. THIS WARMTH PEAKED WITH A
TEMPERATURE OF 59 DEGREES ON FEBRUARY 21, THE SECOND WARMEST
TEMPERATURE EVER OBSERVED IN THE MONTH OF FEBRUARY. ALTHOUGH A COLD
FRONT THAT EVENING BROUGHT COOLER TEMPERATURES BACK INTO THE AREA,
THE REST OF THE MONTH REMAINED ABOVE NORMAL WITH SEVERAL DAYS
REACHING THE 40S.

THE AVERAGE TEMPERATURE FOR THE WINTER WAS 23.3 DEGREES WHICH WAS
0.5 DEGREES ABOVE NORMAL. THE WARMEST WINTER WAS IN 2001-02 WHEN THE
AVERAGE TEMPERATURE WAS 28.6 DEGREES. THE COLDEST WAS IN 1958-59
WHEN IT WAS 17.3 DEGREES.

THE COLD SPELL AROUND NEW YEAR`S WAS ONE OF THE MOST INTENSE ON
RECORD AT AUGUSTA. THE 6 CONSECUTIVE DAYS WITH HIGH TEMPERATURES
BELOW 10 DEGREES TIED AS THE LONGEST ON RECORD AT AUGUSTA. THE
FOLLOWING TABLE LISTS THE LONGEST SUCH STRETCHES ON RECORD.

MOST CONSECUTIVE DAYS MAX < 10 DEGREES (SINCE 1948)...

A TOTAL OF 9.26 INCHES OF PRECIPITATION FELL WHICH WAS 0.98 INCHES
ABOVE NORMAL. THE HEAVIEST PRECIPITATION FELL DURING THE JANUARY
THAW ON JANUARY 12-13 WHEN 2.44 INCHES OF RAIN BROUGHT ICE JAM
FLOODING ALONG THE KENNEBEC RIVER. THE WETTEST WINTER WAS IN 1973-74
WHEN 17.78 INCHES OF PRECIPITATION FELL. THE DRIEST WAS IN 1979-80
WHEN ONLY 3.23 INCHES WAS RECORDED.
