...A WARM WINTER WITH BELOW NORMAL SNOWFALL...

WINTER BEGAN WITH A COLD AND SNOWY DECEMBER BUT JANUARY AND FEBRUARY
EXPERIENCED RECORD WARMTH AND SNOWFALL THAT WAS WELL BELOW NORMAL.
DECEMBER PRECIPITATION WAS BELOW NORMAL WHILE JANUARY AND FEBRUARY
WERE WELL ABOVE NORMAL.

THE AVERAGE TEMPERATURE FOR THIS WINTER SEASON WAS 30.8
DEGREES...3.8 DEGREES ABOVE NORMAL. THIS RANKED AS THE 12TH WARMEST
WINTER SEASON ON RECORD AND WAS ACTUALLY 0.2 DEGREES COOLER THAN
LAST WINTER WHICH RANKED AS THE 9TH WARMEST WINTER. THE WARMEST
WINTER ON RECORD IS 1931-32 WITH AN AVERAGE TEMPERATURE OF 35.3
DEGREES.

WINTER PRECIPITATION WAS 8.98 INCHES...2.13 INCHES ABOVE NORMAL.
THIS RANKED AS THE 24TH WETTEST WINTER ON RECORD.

DESPITE ABOVE NORMAL PRECIPITATION...SNOWFALL WAS WELL BELOW NORMAL.
A TOTAL OF 33.2 INCHES WAS MEASURED...19.7 INCHES BELOW NORMAL. THIS
RANKED AS THE 38TH LEAST SNOWIEST WINTER. JUST OVER 70 PERCENT OF
THE WINTER SEASON SNOWFALL FELL IN DECEMBER. THERE WAS ONLY 9.1
INCHES OF SNOW IN JANUARY AND 0.4 INCHES IN FEBRUARY.

...COLD AND SNOWY DECEMBER WITH BELOW NORMAL PRECIPITATION...

THE FIRST MONTH OF WINTER 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. LITTLE DID WE KNOW THAT THIS WOULD BE THE
COLDEST AND SNOWIEST PART OF THE WINTER SEASON WITH MODERATING
TEMPERATURES IN JANUARY AND ESPECIALLY FEBRUARY. THIS FIRST ARCTIC
BLAST ALSO BROUGHT A LENGTHY PERIOD OF LAKE EFFECT SNOW ALONG WITH
SNOW FROM SEVERAL LOW PRESSURE SYSTEMS.

THE ARCTIC COLD FINALLY BEGAN TO RETREAT MID MONTH AND BY THE DAY
AFTER CHRISTMAS TEMPERATURES BRIEFLY ROSE INTO THE 50S AHEAD OF A
COLD FRONT. THESE MILD TEMPERATURES HELPED PRODUCE FOG AND DRIZZLE
WHICH QUICKLY DEPLETED THE SNOW PACK THAT HAD BEEN IN PLACE. THE
MONTH ENDED WITH NEAR NORMAL TEMPERATURES AND SOME ADDITIONAL LAKE
EFFECT SNOW.

THE AVERAGE MONTHLY TEMPERATURE WAS 25.4 DEGREES...3.4 DEGREES BELOW
NORMAL. THIS RANKED AS TIED WITH 1934 FOR THE 29TH COLDEST DECEMBER
ON RECORD DATING BACK TO 1893. THE WARMEST TEMPERATURE WAS 53 ON THE
26TH AND THE COLDEST WAS 14 BELOW ZERO ON THE 19TH. THE 53 WAS THE
16TH WARMEST MAX TEMPERATURE RECORDED. THE WARMEST WAS 70 SET IN
2001. THE 14 BELOW ZERO WAS A RECORD LOW FOR THE 19TH AND ALSO THE
4TH COLDEST DECEMBER TEMPERATURE RECORDED AT SOUTH BEND. THIS WAS
ALSO THE COLDEST DECEMBER TEMPERATURE SINCE 1983 WHEN IT WAS 15
BELOW ZERO. THE LOWEST RECORDED DECEMBER TEMPERATURE WAS 18 BELOW
SET IN 1924.

PRECIPITATION WAS 1.99 INCHES...0.62 INCHES BELOW NORMAL. THIS
RANKED AS THE 47TH DRIEST DECEMBER ON RECORD. MEASURABLE
PRECIPITATION FELL ON 18 DAYS WITH A HALF INCH OR MORE ON ONE DAY.

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 23.7 INCHES OF SNOW WAS RECORDED...6.4 INCHES ABOVE
NORMAL. THIS RANKED AS THE 20TH SNOWIEST DECEMBER ON RECORD. THE
GREATEST SINGLE DAY SNOWFALL WAS 7.0 INCHES ON THE 11TH.

...MILD AND WET JANUARY BUT WELL BELOW NORMAL SNOWFALL...

DESPITE ABOVE NORMAL PRECIPITATION THIS MONTH...SNOWFALL AT SOUTH
BEND INTERNATIONAL AIRPORT WAS WELL BELOW NORMAL. THIS WAS DUE TO
THE VERY MILD TEMPERATURES THAT OCCURRED FOR MUCH OF THE MONTH.

JANUARY BEGAN MILD AND WET WITH OVER A HALF INCH OF RAIN FALLING ON
THE 2ND. AN ARCTIC COLD FRONT PUT A QUICK END TO THESE ABOVE NORMAL
TEMPERATURES AND THE 5TH THROUGH THE 8TH EXPERIENCED AVERAGE
TEMPERATURES MORE THAN 10 DEGREES BELOW NORMAL. THE COLDEST DAY OF
THE MONTH OCCURRED DURING THIS STRETCH ON THE 6TH WITH A HIGH
TEMPERATURE OF JUST 9 AND A LOW OF NEGATIVE 2 FOR AN AVERAGE DAILY
TEMPERATURE OF 4 DEGREES...21 DEGREES BELOW NORMAL. TEMPERATURES
QUICKLY MODERATED AND A HIGH TEMPERATURE OF 50 DEGREES WAS REACHED
ON THE 10TH. THE REMAINDER OF JANUARY WAS VERY MILD WITH ONLY TWO
DAYS BETWEEN THE 10TH AND 31ST EXPERIENCING BELOW NORMAL
TEMPERATURES.

A RECORD OF 9 CONSECUTIVE DAYS ABOVE FREEZING WAS SET DURING THE
MIDDLE OF THE MONTH FROM JANUARY 17TH THROUGH THE 25TH. THE WARMEST
TEMPERATURE DURING THIS STRETCH WAS 61 ON THE 21ST AND THE COLDEST
TEMPERATURE WAS 33. THIS BROKE THE OLD RECORD OF 8 DAYS FROM JANUARY
2ND THROUGH THE 9TH IN 1992.

THE AVERAGE MONTHLY TEMPERATURE WAS 29.7...5.3 DEGREES ABOVE NORMAL.
THIS RANKED AS THE 18TH WARMEST JANUARY ON RECORD. THE HIGHEST
TEMPERATURE FOR THE MONTH WAS 61 ON THE 21ST AND THE COLDEST WAS
NEGATIVE 4 DEGREES ON THE 7TH. THERE WERE ONLY 11 DAYS WHERE THE
HIGH TEMPERATURE DID NOT GET ABOVE FREEZING.

JANUARY PRECIPITATION WAS 3.34 INCHES...1.05 INCHES ABOVE NORMAL.
THIS RANKED AS THE 26TH WETTEST JANUARY ON RECORD. MEASURABLE
PRECIPITATION FELL ON 19 DAYS AND TWO DAYS HAD A HALF INCH OR MORE
OF PRECIPITATION.

SNOWFALL FOR THE MONTH WAS 9.1 INCHES...11.5 INCHES BELOW NORMAL.
THIS RANKED AS 35TH LEAST SNOWIEST JANUARY. MEASURABLE SNOW FELL ON
11 DAYS BUT THE GREATEST SINGLE DAY SNOWFALL WAS JUST 2.2 INCHES ON
THE 29TH.

...RECORD WARM FEBRUARY WITH WELL BELOW NORMAL SNOWFALL...

IT WAS AN INCREDIBLY WARM AND WET FEBRUARY IN THE SOUTH BEND AREA
WITH ABOVE NORMAL PRECIPITATION AND SNOWFALL THAT WAS WELL BELOW
NORMAL. THE DAILY TEMPERATURES DURING FEBRUARY AVERAGED BELOW NORMAL
ON JUST FIVE DAYS WHILE 14 DAYS AVERAGED MORE THAN 10 DEGREES ABOVE
NORMAL. THERE WERE SIX DAYS THAT AVERAGED 20 DEGREES OR MORE ABOVE
NORMAL. PRECIPITATION WAS WELL ABOVE NORMAL BUT DUE TO THE WARM
TEMPERATURES JUST ABOUT ALL OF IT FELL AS LIQUID WITH JUST 0.4
INCHES OF SNOW FALLING DURING THE ENTIRE MONTH.

THE AVERAGE MONTHLY TEMPERATURE WAS 37.3 DEGREES...9.5 DEGREES ABOVE
NORMAL. THIS RANKED AS THE WARMEST FEBRUARY ON RECORD. THE PREVIOUS
RECORD WAS 37.0 DEGREES SET IN 1998. THE WARMEST TEMPERATURE WAS 66
ON THE 18TH AND THE COLDEST WAS 11 ON THE 4TH. THE 66 WAS THE 5TH
WARMEST FEBRUARY TEMPERATURE EVER RECORDED IN SOUTH BEND. THE
AVERAGE HIGH TEMPERATURE FOR THE MONTH WAS 47.4 DEGREES. THIS WAS A
RECORD...SURPASSING THE PREVIOUS RECORD OF 45.1 SET IN 1976. THE
AVERAGE LOW TEMPERATURE WAS 27.3. THIS RANKED AS THE 5TH WARMEST
MEAN LOW TEMPERATURE FOR FEBRUARY. THERE WERE ONLY 4 DAYS WITH A
HIGH TEMPERATURE THAT DID NOT REACH 32 DEGREES.

THERE WERE 7 DAYS IN FEBRUARY WITH A HIGH TEMPERATURE OF 60 DEGREES
OR WARMER. THIS TIED WITH 1930 AS THE MOST NUMBER OF 60 DEGREE DAYS
IN FEBRUARY. HALF OF THE DAYS...14...HAD A HIGH TEMPERATURE OF 50
DEGREES OR WARMER. THIS WAS A RECORD...SURPASSING 1976 WHICH HAD 13
DAYS ABOVE 50 DEGREES.

FEBRUARY WAS A WET MONTH WITH 3.65 INCHES OF PRECIPITATION BEING
RECORDED. THIS WAS 1.70 INCHES ABOVE NORMAL AND RANKED AS THE 11TH
WETTEST FEBRUARY. NEARLY HALF OF THIS PRECIPITATION FELL ON THE LAST
DAY OF THE MONTH AND NEARLY 90 PERCENT OF THE MONTHLY PRECIPITATION
FELL ON JUST TWO DAYS...THE 7TH AND 28TH. THE RAIN THAT FELL ON EACH
OF THESE TWO DAYS ALSO BROKE SINGLE DAY RAINFALL RECORDS.

MEASURABLE SNOW FELL ON JUST 3 DAYS FOR A TOTAL OF ONLY 0.4 INCHES.
THIS WAS 14.6 INCHES BELOW NORMAL AND RANKED AS THE 2ND LEAST
SNOWIEST FEBRUARY ON RECORD. THE RECORD IS A TRACE SET IN 1998.
