...A WINTER SEASON TO REMEMBER...

IT WAS ONE OF THE COLDEST AND SNOWIEST WINTER SEASONS ON RECORD AND
CERTAINLY ONE OF THE MOST EXTREME WINTER SEASONS IN DECADES.

...A COLD DECEMBER WITH NEAR NORMAL PRECIPITATION...

DECEMBER ACTUALLY BEGAN THE WINTER SEASON RELATIVELY MILD AT SOUTH
BEND WITH HIGH TEMPERATURES IN THE 40S AND 50S FOR THE FIRST 5 DAYS.
THE HIGHEST TEMPERATURE OF THE MONTH WAS 59 ON THE 4TH. THIS WOULD
ACTUALLY TURN OUT TO BE THE WARMEST DAY OF THE ENTIRE WINTER SEASON.
THIS WARMTH WAS SHORT LIVED AS THE FIRST OF NUMEROUS ARCTIC COLD
FRONTS BEGAN TO ESTABLISH THE VERY COLD AIR WHICH WOULD BECOME
ENTRENCHED ACROSS THE REGION FOR THE DURATION OF THE WINTER.

THE AVERAGE TEMPERATURE FOR DECEMBER WAS 26.1 DEGREES...2.7 DEGREES
BELOW NORMAL. THIS RANKED AS THE 37TH COLDEST DECEMBER ON RECORD.
THE COLDEST TEMPERATURE OF THE MONTH WAS 3 DEGREES BELOW ZERO ON THE
12TH. PRECIPITATION FOR THE MONTH WAS 2.33 INCHES...0.28 INCHES
BELOW NORMAL. THIS RANKED AS THE 56TH DRIEST DECEMBER ON RECORD.

SNOWFALL AT SOUTH BEND WAS BASED ON VOLUNTEER WEATHER OBSERVER
REPORTS. APPROXIMATELY 18.5 INCHES OF SNOW WAS OBSERVED...1.2 INCHES
ABOVE THE NORMAL OF 17.3 INCHES. THIS WOULD TIE WITH 1964 AS THE
37TH SNOWIEST DECEMBER ON RECORD.

...JANUARY GETS COLDER WITH A LOT OF SNOW...

THE COLDER THAN NORMAL WINTER BECAME BITTERLY COLD AND HARSH IN
JANUARY WITH RECORD COLD TEMPERATURES...NEAR BLIZZARD CONDITIONS AT
TIMES...DANGEROUS WIND CHILLS AND A LOT OF SNOW. JANUARY BEGAN COLD
WITH THE 2ND AND 3RD HAVING AVERAGE TEMPERATURES NEARLY 20 DEGREES
BELOW NORMAL AND LOW TEMPERATURES IN THE SINGLE DIGITS BELOW ZERO.
THIS WAS JUST A TEASE OF WHAT WAS ABOUT TO COME A FEW DAYS LATER.
ONE OF THE COLDEST OUTBREAKS IN RECENT MEMORY ARRIVED ON JANUARY 6TH
IN THE WAKE OF ONE OF THE MOST MEMORABLE SNOWFALLS IN RECENT DECADES.
A STRONG STORM SYSTEM MOVED THROUGH THE OHIO VALLEY AND DROPPED
BETWEEN 10 AND 18 INCHES OF SNOW ON MANY LOCATIONS ACROSS NORTHERN
INDIANA AND SOUTHWEST LOWER MICHIGAN. THIS STORM WAS ACCOMPANIED BY
WINDS OF 25 TO 35 MPH WHICH CREATED BLOWING AND DRIFTING SNOW AND
WHITEOUT CONDITIONS IN SOME AREAS. AS THE TEMPERATURE FELL BELOW
ZERO ON THE 6TH...WIND CHILLS PLUMMETED TO AROUND 40 BELOW ZERO. LOW
TEMPERATURES DROPPED BELOW ZERO FOR 4 CONSECUTIVE NIGHTS BETWEEN THE
6TH AND 9TH. A BRIEF WARMUP OCCURRED BETWEEN THE 10TH AND 13TH AS
TEMPERATURES WARMED INTO THE 40S. MORE SEASONABLE TEMPERATURES
FOLLOWED THROUGH THE 20TH BEFORE YET ANOTHER PLUNGE OF VERY COLD
ARCTIC AIR MADE ITS WAY BACK TO THE REGION. THIS SYSTEM WAS
ACCOMPANIED BY SNOW AND VERY STRONG WINDS AS WELL. LOW TEMPERATURES
DROPPED TO 14 BELOW ZERO AT SOUTH BEND ON THE 28TH AND WIND CHILLS
ONCE AGAIN DROPPED TO NEAR 35 BELOW ZERO.

THE AVERAGE MONTHLY TEMPERATURE WAS 16.3 DEGREES...8.1 DEGREES BELOW
NORMAL. THIS RANKED AS THE 9TH COLDEST JANUARY ON RECORD. THERE WERE
10 DAYS WITH TEMPERATURES BELOW ZERO. PRECIPITATION FOR THE MONTH
WAS 3.12 INCHES...0.83 INCHES ABOVE NORMAL. THIS RANKED AS THE 29TH
WETTEST JANUARY ON RECORD.

SNOWFALL AT SOUTH BEND WAS BASED ON VOLUNTEER WEATHER OBSERVER
REPORTS. APPROXIMATELY 46.6 INCHES OF SNOW WAS OBSERVED...26.6
INCHES ABOVE THE NORMAL OF 20.6 INCHES. THIS WOULD RANK AS THE 3RD
SNOWIEST JANUARY ON RECORD. THE RECORD WAS SET IN 1978 WITH 86.1
INCHES.

...FEBRUARY GETS EVEN COLDER WITH MORE SNOW TO END THE WINTER
SEASON...

FEBRUARY CONTINUED A STREAK OF MONTHS WITH BELOW NORMAL TEMPERATURES
IN THE SOUTH BEND AREA. THIS WAS THE FOURTH CONSECUTIVE MONTH WITH
BELOW NORMAL TEMPERATURES...AND IT WAS ALSO THE COLDEST MONTH OF THE
WINTER SEASON. IT WAS ALSO ANOTHER VERY SNOWY MONTH BASED ON
VOLUNTEER WEATHER OBSERVER REPORTS FROM AROUND THE REGION.

THE OVERALL WINTER WEATHER PATTERN THAT KEPT THE CENTRAL UNITED
STATES VERY COLD CONTINUED INTO FEBRUARY. THERE WAS A BRIEF
BREAKDOWN DURING THE MIDDLE OF THE MONTH AND THIS ALLOWED
TEMPERATURES TO BRIEFLY WARM ABOVE NORMAL. HOWEVER...THIS REPRIEVE
FROM THE DEEP FREEZE WAS SHORT LIVED AS VERY COLD AIR RETURNED FOR
THE END OF THE MONTH.

THERE WERE ONLY 5 DAYS IN FEBRUARY WITH A DAILY AVERAGE TEMPERATURE
ABOVE NORMAL.HALF OF THE DAYS IN FEBRUARY...14...SAW AN AVERAGE
DAILY TEMPERATURE TEN DEGREES OR MORE BELOW NORMAL. THE COLDEST
TEMPERATURE OF THE MONTH WAS 8 BELOW ZERO ON THE 11TH. THE AVERAGE
MONTHLY TEMPERATURE WAS JUST 18.4 DEGREES...9.4 DEGREES BELOW
NORMAL. THIS ONLY RANKED AS THE 12TH COLDEST FEBRUARY ON RECORD.
FEBRUARY 1904 WAS THE COLDEST WITH AN AVERAGE TEMPERATURE OF 14.4
DEGREES. THERE WERE 8 DAYS WITH A LOW TEMPERATURE BELOW ZERO IN
FEBRUARY. FEBRUARY 1904 AND 1936 HOLD THE RECORD OF 14 DAYS WITH A
LOW TEMPERATURE OF ZERO OR COLDER.

PRECIPITATION FOR FEBRUARY WAS ABOVE NORMAL WITH A TOTAL OF 2.82
INCHES FALLING. THIS WAS 0.87 INCHES ABOVE NORMAL AND RANKED AS JUST
THE 20TH WETTEST FEBRUARY ON RECORD. MEASURABLE PRECIPITATION FELL
ON 11 DAYS WITH THE GREATEST 24 HOUR PRECIPITATION BEING 1.64 INCHES
ON THE 20TH. MOST OF THIS PRECIPITATION FELL IN THE FORM OF RAIN
DURING THE SHORT PERIOD WHICH HAD WARMER THAN NORMAL TEMPERATURES.

SNOWFALL AT SOUTH BEND WAS BASED ON VOLUNTEER WEATHER OBSERVER
REPORTS. APPROXIMATELY 19.7 INCHES OF SNOW WAS OBSERVED...4.7 INCHES
ABOVE THE NORMAL OF 15 INCHES. THIS WOULD RANK AS THE 22ND SNOWIEST
FEBRUARY ON RECORD.

...ENTIRE WINTER SEASON ENDS UP BEING VERY COLD AND SNOWY...

THE AVERAGE WINTER SEASON TEMPERATURE AT SOUTH BEND REGIONAL AIRPORT
WAS 20.3 DEGREES...6.7 DEGREES BELOW THE NORMAL OF 27.0. THIS RANKED
AS THE 7TH COLDEST WINTER SEASON ON RECORD AT SOUTH BEND AND THE
COLDEST SEASON SINCE 1977-78. THAT SEASON RANKED 5TH COLDEST AND
1903-1904 RANKED AS THE COLDEST WINTER SEASON WITH AN AVERAGE
TEMPERATURE OF 16.6. EACH MONTH INDIVIDUALLY AVERAGED BELOW NORMAL
TEMPERATURES THIS WINTER AND EACH MONTH BECAME PROGRESSIVELY COLDER
WITH RESPECT TO NORMAL.

PRECIPITATION FOR THE WINTER SEASON WAS 8.27 INCHES...1.42 INCHES
ABOVE NORMAL. THIS ONLY RANKS AS THE 32ND WETTEST WINTER SEASON ON RECORD.
THERE WERE 50 DAYS IN WHICH MEASURABLE PRECIPITATION OCCURRED. THIS
RANKED AS 9TH FOR MOST DAYS WITH MEASURABLE PRECIPITATION IN A
WINTER SEASON. THE WINTER OF 2007-2008 RANKED FIRST WITH 57 DAYS.

THE WINTER SEASON SNOWFALL AT SOUTH BEND WAS BASED ON VOLUNTEER
WEATHER OBSERVER REPORTS. A TOTAL OF 84.8 INCHES OF SNOW WAS
OBSERVED...31.9 INCHES ABOVE THE NORMAL OF 52.9 INCHES. THIS WOULD
RANK AS THE 6TH SNOWIEST WINTER ON RECORD. THE RECORD WAS SET IN
1977-78 WITH 136.3 INCHES. THE WINTER SEASON OF 2010-11 WAS ACTUALLY
MUCH SNOWIER AND THE SECOND SNOWIEST WINTER SEASON ON RECORD WITH
102.8 INCHES.

MANY PEOPLE HAVE EXPRESSED OPINIONS THAT THIS WINTER SEASON WAS ONE
OF THE MOST EXTREME ON RECORD. WHILE IT IS DIFFICULT TO RANK WINTERS
BASED ON COMBINED PARAMETERS...A VERY SIMPLISTIC CALCULATION WAS
DONE USING THE AVERAGE OF THE RANKINGS FOR SNOWIEST AND COLDEST
WINTER SEASONS. THE WINTER OF 1977-78 WAS THE MOST EXTREME WITH THE
SNOWIEST WINTER ON RECORD AND THE 5TH COLDEST WINTER. THE WINTER OF
1962-63 WAS SECOND WITH THE 8TH SNOWIEST BUT 2ND COLDEST WINTER
THE WINTER OF 2013-14 TIED WITH 1976-77 FOR THIRD USING THIS SIMPLE
RANKING SYSTEM. THE WINTER OF 1976-77 WAS THE 4TH SNOWIEST AND 9TH
COLDEST WHILE THE WINTER OF 2013-14 WAS THE 6TH SNOWIEST AND 7TH
COLDEST. THESE NUMBERS REALLY DO NOT MEAN ANYTHING SCIENTIFICALLY
BUT ARE A QUICK AND INTERESTING WAY TO COMPARE SEASONS BASED ON SNOW
AND TEMPERATURE RANKINGS. ONE COULD EASILY ARGUE THAT THE WINTER OF
2013-14 WAS THE COLDEST AND SNOWIEST COMBINED SINCE 1977-78.
