...A WARM DECEMBER WITH NEAR NORMAL PRECIPITATION BUT BELOW NORMAL
SNOWFALL...

DECEMBER WAS CHARACTERIZED BY A MORE ACTIVE WEATHER PATTERN THAN THE
PREVIOUS MONTH WITH SEVERAL STRONG WEATHER SYSTEMS MOVING THROUGH
THE REGION. TEMPERATURES WERE MUCH ABOVE NORMAL FOR THE FIRST 20
DAYS OF THE MONTH WITH AVERAGE TEMPERATURES NEARLY 10 TO 12 DEGREES
ABOVE NORMAL! THIS CAUSED MOST PRECIPITATION TO FALL IN THE FORM OF
RAIN INSTEAD OF SNOW MORE TYPICAL FOR THIS TIME OF YEAR. DECEMBER
ALSO ENDED THE STREAK OF BELOW NORMAL TEMPERATURES FROM AUGUST TO
NOVEMBER. A PATTERN CHANGE FOR THE LAST PART OF THE MONTH ALLOWED
FOR COLDER AIR TO INFILTRATE THE REGION...BRINGING TEMPERATURES
CLOSER TO NORMAL WITH SEVERAL ROUNDS OF LIGHT SNOWFALL. TWO STRONG
WINTER STORMS MOVED THROUGH THE REGION...ONE TO THE NORTHWEST ON THE
20TH AND ONE TO THE SOUTHEAST ON THE 26TH...LEAVING THE LOCAL AREA
JUST OUTSIDE THE FRINGES OF HEAVIEST SNOWFALL AND BLIZZARD
CONDITIONS. DESPITE SLIGHTLY ABOVE NORMAL PRECIPITATION FOR THE
MONTH...D0 TO D1 DROUGHT CONDITIONS CONTINUED ACROSS THE AREA AS
LONG TERM DEFICITS REMAINED SIGNIFICANT WITH BELOW NORMAL WATER
LEVELS ON AREA LAKES AND RIVERS.

TOTAL PRECIPITATION FOR THE MONTH AT FORT WAYNE WAS 2.20 INCHES...0.57
INCHES BELOW NORMAL. MEASURABLE PRECIPITATION FELL ON 15 DAYS OUT OF
THE MONTH WITH 0.80 INCHES FALLING ON THE 20TH AND 21ST.  9.0 INCHES
OF SNOW FELL FOR THE MONTH WHICH IS 0.5 INCHES ABOVE NORMAL. THE
GREATEST 24 HOUR TOTAL OF SNOWFALL WAS 3.1 INCHES WHICH FELL ON
DECEMBER 26TH.

THE AVERAGE MONTHLY TEMPERATURE OF 36.3 DEGREES WAS 7.2 DEGREES ABOVE
NORMAL. THIS RANKS AS THE 6TH WARMEST DECEMBER ON RECORD. A WARM
FIRST HALF OF THE MONTH WITH TEMPERATURES NEARLY 10 TO 15 DEGREES
ABOVE NORMAL ALLOWED FOR MONTHLY AVERAGES MUCH ABOVE NORMAL. THE
WARMEST TEMPERATURE OF THE MONTH WAS ON THE 3RD WHEN THE HIGH
TEMPERATURE REACHED 64 DEGREES. THE LOWEST TEMPERATURE OF THE MONTH
WAS 18 DEGREES ON THE 30TH.
