THE METEOROLOGICAL WINTER SEASON OF 2014-15 BEGAN MILD WITH THE
LEAST SNOWIEST DECEMBER ON RECORD AND ENDED VERY COLD WITH THE
SNOWIEST FEBRUARY ON RECORD. IN BETWEEN...JANUARY WAS NEAR NORMAL.
THIS LARGE VARIATION FROM THE BEGINNING TO THE END LED TO RATHER
BENIGN SEASONAL RANKINGS...DESPITE THE FACT THAT IT FELT LIKE A LONG
AND COLD WINTER TO MANY PEOPLE.

THE AVERAGE TEMPERATURE FOR THE SEASON WAS 23.8 DEGREES...3.2
DEGREES BELOW NORMAL. THIS RANKED AS THE 27TH COLDEST WINTER SEASON.
THE RATHER MILD DECEMBER OFFSET THE VERY COLD FEBRUARY TO NORMALIZE
THE SEASONAL TEMPERATURE.

PRECIPITATION FOR THE PERIOD WAS 5.37 INCHES...1.48 INCHES BELOW
NORMAL. THIS RANKED AS THE 30TH DRIEST WINTER SEASON. SNOWFALL WAS
58.7 INCHES...5.8 INCHES ABOVE NORMAL. THIS RANKED AS THE 21ST
SNOWIEST WINTER SEASON. BELOW IS A MONTH BY MONTH SUMMARY OF HOW THE
WINTER SEASON TRANSPIRED.

AFTER A VERY COLD AND SNOWY NOVEMBER...DECEMBER WAS A DRASTICALLY
DIFFERENT MONTH WITH ABOVE NORMAL TEMPERATURES AND SETTING A RECORD
FOR THE LEAST SNOWIEST DECEMBER ON RECORD.

DECEMBER BEGAN WITH SLIGHTLY BELOW NORMAL TEMPERATURES AND ENDED
WITH TEMPERATURES MUCH BELOW NORMAL...BUT IN BETWEEN MOST DAYS WERE
WARMER THAN NORMAL.

THE WEATHER WAS VERY TRANQUIL AND RELATIVELY MILD DURING THE ENTIRE
MONTH...ESPECIALLY COMPARED TO THE VERY COLD AND SNOWY NOVEMBER. ONLY
A HANDFUL OF WEATHER SYSTEMS BROUGHT PRECIPITATION TO THE SOUTH BEND
AREA. ABOUT HALF OF THE MONTHS PRECIPITATION FELL ON THE 23RD AND
24TH WITH A VERY COMPLEX WINTER STORM SYSTEM THAT MOVED JUST EAST OF
THE LOCAL AREA. WITH COLD AIR LACKING AND WARM MOISTURE FROM THE
PACIFIC AND GULF OF MEXICO STREAMING INTO THE AREA...PRECIPITATION
FELL AS MAINLY RAIN WITH ONLY A FEW WET SNOWFLAKES FALLING ON THE
BACK SIDE AS THIS SYSTEM DEPARTED.

WITH THE LACK OF COLD AIR AND PRECIPITATION PRODUCING WEATHER
SYSTEMS...IT IS NO SURPRISE THAT THE MONTH ENDED AS THE LEAST
SNOWIEST DECEMBER ON RECORD. WHAT IS A SURPRISE IS THAT IT
FOLLOWED A NOVEMBER THAT WAS THE 4TH SNOWIEST ON RECORD WITH 19.3
INCHES OF SNOW.

THE AVERAGE MONTHLY TEMPERATURE WAS 33.2 DEGREES WHICH WAS 4.4
DEGREES ABOVE NORMAL. THIS RANKED AS THE 20TH WARMEST DECEMBER.
THERE WERE JUST 3 DAYS WITH A HIGH TEMPERATURE OF 32 DEGREES OR
COLDER. THE WARMEST TEMPERATURE WAS 55 ON THE 14TH AND THE COLDEST
WAS 8 ON THE 31ST. PRECIPITATION FOR THE MONTH WAS 1.47
INCHES...1.14 INCHES BELOW NORMAL. THIS RANKED AS THE 22ND DRIEST
DECEMBER ON RECORD.

WHILE A TRACE OF SNOW FELL ON 10 DAYS...MEASURABLE SNOW FELL ON JUST
ONE SINGLE DAY...DECEMBER 30TH. ONLY 0.2 INCHES OF SNOW WAS MEASURED
AND THIS MARKS THE LEAST SNOWIEST DECEMBER ON RECORD. THE OLD RECORD
WAS 0.5 INCHES SET IN 1912. THIS ALSO TIED THE RECORD FOR THE FEWEST
NUMBER OF DAYS WITH MEASURABLE SNOWFALL IN DECEMBER AT SOUTH BEND.
DECEMBER 1912 AND DECEMBER 1931 BOTH HAD ONLY 1 DAY OF MEASURABLE
SNOWFALL.

JANUARY WAS A RELATIVELY QUIET AND NORMAL MONTH WITH PERIODS OF COLD
AND SNOWY WEATHER BUT NO STRONG STORM SYSTEMS LIKE 2014.
TEMPERATURES AND PRECIPITATION ENDED UP SLIGHTLY BELOW NORMAL BUT
SNOWFALL WAS ABOVE NORMAL.

THE AVERAGE MONTHLY TEMPERATURE WAS 22.5 DEGREES...1.9 DEGREES BELOW
NORMAL. THIS RANKED AS THE 38TH COLDEST JANUARY ON RECORD. THE
WARMEST TEMPERATURE WAS 46 ON THE 17TH AND THE COLDEST WAS NEGATIVE
9 ON THE 8TH. THERE WERE SIX DAYS WITH A LOW TEMPERATURE OF ZERO OR
COLDER.

PRECIPITATION WAS 1.92 INCHES...0.37 INCHES BELOW NORMAL. THIS
RANKED AS THE 49TH DRIEST JANUARY ON RECORD. SNOWFALL FOR THE MONTH
WAS 22.1 INCHES...1.5 INCHES ABOVE NORMAL. THIS RANKED AS THE 35TH
SNOWIEST JANUARY ON RECORD.

FEBRUARY BEGAN WITH A POWERFUL WINTER STORM THAT DROPPED RECORD
SNOWFALL ACROSS THE MICHIANA AREA. THIS SET THE STAGE FOR A VERY
COLD AND SNOWY MONTH WITH SEVERAL RECORDS BEING BROKEN FOR BOTH SNOW
AND COLD. THE SECOND HALF OF FEBRUARY WAS THE COLDEST ON RECORD.
FITTINGLY...THE MONTH ENDED AS IT STARTED WITH SNOW DURING THE FINAL
HOURS.

A RECORD SNOWFALL OF 14.7 INCHES OCCURRED ON THE FIRST DAY OF THE
MONTH...BREAKING THE OLD RECORD FOR THIS DATE BY MORE THAN 6 INCHES.
THIS WAS ALSO THE HIGHEST SINGLE DAY SNOWFALL FOR ANY DAY IN
FEBRUARY AND RANKED AS THE 8TH HIGHEST SINGLE DAY SNOWFALL FOR ANY
MONTH AT SOUTH BEND.

BRUTALLY COLD ARCTIC AIR ARRIVED ON THE 12TH AND REMAINED ENTRENCHED
ACROSS THE REGION THROUGH THE END OF THE MONTH. EVERY DAY FROM THE
12TH TO THE 28TH OF FEBRUARY HAD AN AVERAGE DAILY TEMPERATURE BELOW
NORMAL. ALL BUT THREE DAYS IN THIS STRETCH HAD AN AVERAGE
TEMPERATURE OF AT LEAST 10 DEGREES BELOW NORMAL AND 9 DAYS SAW THE
AVERAGE TEMPERATURE 20 DEGREES OR MORE BELOW NORMAL. THIS STRETCH OF
FEBRUARY FROM THE 12TH TO THE 28TH WAS...BY FAR...THE COLDEST EVER
RECORDED. THE AVERAGE TEMPERATURE DURING THIS PERIOD WAS JUST 11.6
DEGREES. THE PREVIOUS COLDEST AVERAGE TEMPERATURE FROM THE 12TH TO
28TH WAS 14.6 DEGREES IN 1904.

THE AVERAGE TEMPERATURE FOR THE ENTIRE MONTH OF FEBRUARY WAS 15.8
DEGREES...12.0 DEGREES BELOW NORMAL. THIS RANKED AS THE 5TH COLDEST
FEBRUARY ON RECORD. THE COLDEST WAS 1904 WITH AN AVERAGE TEMPERATURE
OF 14.4 DEGREES. IN COMPARISON...THE AVERAGE TEMPERATURE IN FEBRUARY
2014 WAS 18.4 DEGREES AND THAT RANKED AS THE 13TH COLDEST FEBRUARY.
THE WARMEST TEMPERATURE THIS MONTH WAS 43 DEGREES ON THE 7TH AND 8TH
AND THE COLDEST TEMPERATURE WAS 12 BELOW ZERO ON THE 20TH. THE 43
DEGREE HIGH WAS THE 9TH COLDEST HIGH TEMPERATURE FOR A FEBRUARY
WHILE THE 12 BELOW WAS THE 11TH COLDEST TEMPERATURE EVER RECORDED IN
FEBRUARY.

PRECIPITATION FOR THE MONTH WAS 1.98 INCHES...JUST 0.03 INCHES ABOVE
NORMAL AND TIED AS THE 41ST WETTEST FEBRUARY. DESPITE HAVING NEAR
NORMAL PRECIPITATION...THE VERY COLD AIR ALLOWED NEARLY ALL OF THIS
TO FALL AS SNOW WITH A HIGH RATIO OF SNOW TO LIQUID. TOTAL SNOWFALL
WAS A RECORD 36.4 INCHES...21.4 INCHES ABOVE NORMAL. THIS BROKE THE
PREVIOUS RECORD OF 35.5 INCHES SET IN 1908.

EVERY DAY THIS MONTH HAD A LOW TEMPERATURE BELOW FREEZING AND 24
DAYS HAD A HIGH TEMPERATURE OF 32 DEGREES OR COLDER. MEASURABLE
PRECIPITATION FELL ON 16 DAYS AND ONE DAY...THE FIRST...HAD OVER AN
INCH OF PRECIPITATION WHICH WAS ABOUT HALF OF THE MONTHLY TOTAL. THE
LOWEST SNOW DEPTH FOR THE MONTH WAS 3 INCHES AT 7AM ON THE FIRST.
THE LOWEST SNOW DEPTH AFTER THIS WAS 6 INCHES. THERE WERE 16 DAYS
WITH A SNOW DEPTH OF 10 INCHES OR GREATER. FEBRUARY 2015 TIES THE
YEARS OF 1967...1978 AND 1979 WITH 3 INCHES OR MORE OF SNOW DEPTH ON
EVERY DAY OF THE MONTH.
