...AN EXTREMELY COLD AND SNOWY FEBRUARY IN SOUTH BEND AREA...

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. AS A MATTER OF FACT...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.

MEASURABLE SNOW CONTINUED TO FALL AT SOUTH BEND THROUGH THE 5TH.
SEASONABLE TEMPERATURES AND GENERALLY DRY CONDITIONS THEN FOLLOWED
UNTIL THE 12TH. THIS WAS WHEN THE FIRST WAVE OF BRUTALLY COLD ARCTIC
AIR ARRIVED 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.
