...A MILD START TO METEOROLOGICAL WINTER...

AFTER A COLD NOVEMBER WITH ABOVE NORMAL SNOWFALL, THE FIRST MONTH OF
THE METEOROLOGICAL WINTER SEASON WAS MILD WITH NEAR NORMAL
PRECIPITATION AND BELOW NORMAL SNOWFALL. DECEMBER PRECIPITATION WAS
ACTUALLY AN INCH BELOW NORMAL ON THE 30TH, BUT MODERATE TO LOCALLY
HEAVY RAINFALL OF OVER AN INCH ON THE LAST DAY OF THE MONTH AND YEAR
BROUGHT THE MONTHLY PRECIPITATION TOTAL BACK UP TO SLIGHTLY ABOVE
NORMAL.

IT WAS A RATHER UNEVENTFUL FIRST MONTH OF WINTER WITH MILD
TEMPERATURES AND LITTLE IN THE WAY OF SNOW. DECEMBER BEGAN MILD AND
WET WITH JUST OVER THREE QUARTERS OF AN INCH OF RAINFALL ON THE
FIRST TWO DAYS AND HIGH TEMPERATURES IN THE 50S, REACHING 59 ON THE
2ND. THE COLDEST PERIOD OF THE MONTH AND THE ONLY DAYS WITH AN
AVERAGE TEMPERATURE BELOW NORMAL OCCURRED FROM THE 4TH THROUGH THE
10TH. THE ONLY MEASURABLE SNOW OF THE MONTH, 0.1 INCHES, FELL DURING
THIS PERIOD ON DECEMBER 5TH. THE REMAINDER OF DECEMBER WAS MILD AND
RELATIVELY DRY UNTIL THE 31ST.

THE AVERAGE MONTHLY TEMPERATURE WAS 35.8, 6.7 DEGREES ABOVE NORMAL.
THIS RANKED AS THE 12TH WARMEST DECEMBER ON RECORD, TIED WITH 1994.
THIS MONTHLY AVERAGE TEMPERATURE WAS JUST OVER A DEGREE COLDER THAN
THE NOVEMBER AVERAGE TEMPERATURE. NORMALLY THE DECEMBER MONTHLY
AVERAGE TEMPERATURE IS ABOUT 12 DEGREES COLDER THAN NOVEMBER. THE
WARMEST TEMPERATURE WAS 59 ON THE 2ND AND 31ST WHILE THE COLDEST WAS
16 ON THE 9TH.

MONTHLY PRECIPITATION WAS 2.94 INCHES, 0.17 INCHES ABOVE NORMAL.
THIS RANKED AS THE 35TH WETTEST MONTH ON RECORD. MOST OF THIS
PRECIPITATION FELL ON THE FIRST TWO DAYS AND LAST DAY OF THE MONTH.
A TOTAL OF 1.26 INCHES FELL ON THE 31ST, WHICH WAS A RECORD FOR THAT
DATE. THERE WERE 12 DAYS WITH MEASURABLE PRECIPITATION.

SNOWFALL FOR THE MONTH WAS WELL BELOW NORMAL WITH JUST 0.1 INCHES
FALLING. THIS WAS 8.4 INCHES BELOW NORMAL AND RANKED AS THE 2ND
LEAST SNOWIEST DECEMBER ON RECORD, BEHIND 1931 WHICH ONLY RECORDED A
TRACE OF SNOWFALL.
