DECEMBER

IT WAS A VERY WARM AND WET DECEMBER WITH RECORD WARMTH AND ABOVE
NORMAL PRECIPITATION. THOSE WISHING FOR SNOW AND A WHITE CHRISTMAS
WERE DISAPPOINTED AS NEARLY ALL OF THE PRECIPITATION FELL AS RAIN OR
SLEET WHILE CHRISTMAS DAY WAS SUNNY...MILD AND GREEN FOR LATE
DECEMBER.

THIS PAST FALL AND FIRST MONTH OF WINTER SAW THE DEVELOPMENT OF THE
SECOND STRONGEST EL NINO SINCE MODERN RECORDS BEGAN IN 1950. EL NINO
OCCURS WHEN THE WATER TEMPERATURES OF THE PACIFIC OCEAN ALONG THE
EQUATOR WARM ABOVE NORMAL FOR SEVERAL MONTHS IN A ROW. THIS IN TURN
CAN EFFECT ATMOSPHERIC WEATHER PATTERNS INCLUDING THE LOCATION OF
WHAT IS KNOWN AS THE SUBTROPICAL AND POLAR JET STREAMS AS THEY MOVE
ACROSS NORTH AMERICA. THE STRONG EL NINO COUPLED WITH OTHER
ATMOSPHERIC PARAMETERS IN THE NORTHERN POLE REGIONS LIKELY
CONTRIBUTED TO OUR RECORD WARM DECEMBER IN THE FORT WAYNE AREA.

DECEMBER WAS SO WARM THAT THERE WERE ONLY 2 DAYS WITH AVERAGE
TEMPERATURES BELOW NORMAL...AND THEY WERE JUST BARELY BELOW NORMAL.
THOSE DAYS WERE THE 2ND AND 19TH...JUST 1 DEGREE AND 2 DEGREES BELOW
NORMAL RESPECTIVELY. IN CONTRAST...THERE WERE 18 DAYS WITH AN
AVERAGE TEMPERATURE OF 10 DEGREES OR MORE ABOVE NORMAL AND 7 OF
THOSE DAYS WERE MORE THAN 20 DEGREES ABOVE NORMAL WHILE 2 DAYS...THE
12TH AND 13TH...WERE MORE THAN 30 DEGREES ABOVE NORMAL. CHRISTMAS
DAY WAS EVEN MILD WITH MOSTLY SUNNY AND DRY CONDITIONS. THE HOLIDAY
WAS A FESTIVE GREEN RATHER THAN SNOWY WHITE THANKS TO THE WARM
TEMPERATURES AND LACK OF SNOWFALL DURING THE MONTH. THE CHRISTMAS
DAY HIGH TEMPERATURE WAS 49...THE LOW WAS 37 AND THE AVERAGE
TEMPERATURE WAS 43...16 DEGREES ABOVE NORMAL.

THIS DECEMBER SHATTERED A RECORD FOR THE GREATEST NUMBER OF DAYS
WITH HIGH TEMPERATURES OF 50 DEGREES OR WARMER. NEARLY HALF OF THE
DAYS IN DECEMBER...15...HAD A HIGH TEMPERATURE OF AT LEAST 50. THIS
BREAKS THE OLD RECORD OF 11 SET IN ANOTHER EL NINO DECEMBER...1982.
THERE WERE 4 DAYS WITH HIGH TEMPERATURES OF AT LEAST 60 DEGREES AND
THIS RANKED 3RD. DECEMBER 1982 HOLDS THE RECORD WITH 8.

THE AVERAGE HIGH TEMPERATURE FOR DECEMBER WAS AN AMAZING 48.6
DEGREES...12.4 DEGREES ABOVE THE NORMAL OF 36.2. THIS RANKED AS THE
WARMEST AVERAGE DECEMBER HIGH TEMPERATURE ON RECORD...CRUSHING THE
PREVIOUS RECORD OF 45.6 DEGREES SET IN 1923. THE AVERAGE LOW
TEMPERATURE WAS 34.5 DEGREES...12.4 DEGREES ABOVE THE NORMAL OF
22.1. THIS ALSO RANKED AS THE WARMEST AVERAGE DECEMBER LOW
TEMPERATURE ON RECORD. THIS AVERAGE LOW WAS ALMOST AS WARM AS THE
NORMAL AVERAGE HIGH TEMPERATURE FOR THE MONTH.

THE AVERAGE MONTHLY TEMPERATURE FOR DECEMBER WAS A VERY WARM 41.5
DEGREES...12.4 DEGREES ABOVE NORMAL. THIS RANKED AS THE WARMEST
DECEMBER ON RECORD...SURPASSING 1982 WHICH ALSO HAPPENED TO BE ONE
OF THE STRONGEST RECORDED EL NINO EVENTS SINCE 1950. THE HIGHEST
TEMPERATURE THIS MONTH WAS 69 ON THE 12TH...WHICH WAS THE SECOND
WARMEST HIGH TEMPERATURE EVER RECORDED IN DECEMBER. THE RECORD IS
71...SET IN 1982. THE LOWEST TEMPERATURE THIS MONTH WAS 21 ON THE
19TH. THIS TIED 1994 AS THE WARMEST LOW TEMPERATURE FOR A DECEMBER
ON RECORD.

WHILE MONTHLY PRECIPITATION WAS NOT RECORD BREAKING...IT WAS STILL
IMPRESSIVE AND WELL ABOVE NORMAL FOR DECEMBER WITH ONE DAILY
PRECIPITATION RECORD BEING SET. TOTAL PRECIPITATION WAS 4.15
INCHES...1.38 INCHES ABOVE NORMAL. THIS RANKED AS THE 14TH WETTEST
DECEMBER ON RECORD. THERE WERE 13 DAYS WITH MEASURABLE
PRECIPITATION...4 DAYS WITH A HALF INCH OR MORE...AND 1 DAY WITH AN
INCH OR MORE OF PRECIPITATION. A DAILY PRECIPITATION RECORD WAS SET
ON DECEMBER 28TH WHEN 1.12 INCHES OF PRECIPITATION WAS
MEASURED...BREAKING THE OLD DAILY RECORD OF 0.98 INCHES SET IN 1948.

DECEMBER SNOWFALL WAS WELL BELOW NORMAL WITH JUST 0.2 INCHES...8.3
INCHES BELOW NORMAL. THIS TIED 1912 AND 1943 AS THE 2ND LEAST
SNOWIEST DECEMBER ON RECORD. THE LEAST SNOWIEST DECEMBER ON RECORD
