THE FINAL MONTH OF 2016 EXPERIENCED A VARIETY OF WEATHER. DECEMBER
BEGAN WITH NEAR NORMAL TEMPERATURES BUT AN ARCTIC COLD FRONT ARRIVED
LATE IN THE SECOND WEEK AND BROUGHT SOME OF THE COLDEST DECEMBER
TEMPERATURES IN DECADES. THIS ARCTIC COLD AIR ALSO BROUGHT SOME SNOW
WITH OVER 6 INCHES BEING RECORDED JUST PRIOR TO ITS ARRIVAL.

THE ARCTIC COLD FINALLY BEGAN TO RETREAT AFTER THE 20TH AND BY THE
DAY AFTER CHRISTMAS...TEMPERATURES BRIEFLY ROSE INTO THE LOWER 60S
AHEAD OF A COLD FRONT. THESE RECORD MILD TEMPERATURES HELPED PRODUCE
FOG AND DRIZZLE WHICH QUICKLY DEPLETED THE SNOW PACK THAT WAS IN
PLACE. SHOWERS DEVELOPED AHEAD OF THE COLD FRONT ON THE 26TH AND
BROUGHT THREE QUARTERS OF AN INCH OF RAIN TO THE FORT WAYNE AREA.
THE MONTH ENDED WITH NEAR NORMAL TEMPERATURES AND SOME ADDITIONAL
LIGHT SNOW.

THE AVERAGE MONTHLY TEMPERATURE WAS 27.1 DEGREES...2.0 DEGREES BELOW
NORMAL. THIS RANKED AS THE 32ND COLDEST DECEMBER ON RECORD DATING
BACK TO 1912. THE WARMEST TEMPERATURE WAS 60 ON THE 26TH AND THE
COLDEST WAS 9 BELOW ZERO ON THE 19TH. THE 60 WAS A RECORD FOR THE
26TH AND THE 10TH WARMEST MAX TEMPERATURE RECORDED IN DECEMBER. THE
WARMEST WAS 71 SET IN 1982. THE 9 BELOW ZERO WAS A RECORD LOW FOR
THE 19TH AND ALSO THE 10TH COLDEST DECEMBER TEMPERATURE RECORDED AT
FORT WAYNE. THIS WAS ALSO THE COLDEST DECEMBER TEMPERATURE SINCE
2004 WHEN IT WAS 15 BELOW ZERO. THE LOWEST RECORDED DECEMBER
TEMPERATURE WAS 18 BELOW SET IN 1989.

PRECIPITATION WAS 2.31 INCHES...0.46 INCHES BELOW NORMAL. THIS
RANKED AS THE 52ND DRIEST DECEMBER ON RECORD. MEASURABLE
PRECIPITATION FELL ON 13 DAYS WITH A HALF INCH OR MORE ON TWO DAYS.
ABOUT 75 PERCENT OF THE PRECIPITATION FOR THE MONTH FELL ON 3
DAYS...THE 4TH...11TH AND 26TH. THE 0.76 INCHES WHICH FELL ON THE
26TH RANKED AS THE 4TH MOST PRECIPITATION FOR THAT DATE.

DESPITE HAVING BELOW NORMAL PRECIPITATION...THE MONTH DID END WITH
ABOVE NORMAL SNOWFALL. THIS WAS PRIMARILY DUE TO THE VERY COLD
TEMPERATURES MID MONTH HELPING LEAD TO LARGER LIQUID TO SNOW RATIOS.
A TOTAL OF 10.9 INCHES OF SNOW WAS RECORDED...2.4 INCHES ABOVE
NORMAL. THIS RANKED AS TIED WITH 2010 AND 2003 AS THE 19TH SNOWIEST
DECEMBER ON RECORD. THE GREATEST SINGLE DAY SNOWFALL WAS 6.3 INCHES
ON THE 11TH.
