JANUARY

...JANUARY WAS LIKE A WEATHER ROLLER COASTER...

DRAMATIC UPS AND DOWNS IN TEMPERATURES DURING THE MONTH MADE IT FEEL
LIKE A WEATHER ROLLER COASTER. HIGH TEMPERATURES TOPPED OUT NEAR 60
DEGREES AND LOW TEMPERATURES BOTTOMED OUT AROUND ZERO DEGREES.
JANUARY ALSO SAW ABOVE NORMAL PRECIPITATION WITH A FEW DAYS OF
MODERATE TO HEAVY RAINFALL. THIS HELPED RAISE WATER LEVELS ON AREA
LAKES AND RIVERS AND EVEN LED TO SOME MINOR FLOODING.

THE ROLLER COASTER RIDE BEGAN WITH TEMPERATURES SLIGHTLY BELOW
NORMAL AND RELATIVELY DRY CONDITIONS TO START THE MONTH.
A JANUARY THAW OCCURRED DURING THE SECOND WEEK AS HIGHS CLIMBED INTO
THE 40S AND TOPPED OUT IN THE UPPER 50S ON JANUARY 12TH. THE HIGH ON
THIS DAY IN SOUTH BEND WAS 58. THIS WARM UP WAS ALSO ACCOMPANIED BY
OVER AN INCH OF MUCH NEEDED RAINFALL WHICH OCCURRED BETWEEN THE 10TH
AND 13TH. THIS WARM RESPITE WAS SHORT LIVED AS MORE SEASONABLE
TEMPERATURES RETURNED ON THE 13TH...FOLLOWED BY A MILD WARM UP ON
THE 19TH.

SNOWFALL THROUGH JANUARY 20TH WAS WELL BELOW NORMAL WITH ONLY THREE
TENTHS OF AN INCH BEING RECORDED. THE REMAINDER OF THE MONTH WAS A
DIFFERENT STORY AS THE FIRST SIGNIFICANT ARCTIC OUTBREAK OF THE
SEASON BROUGHT TEMPERATURES CRASHING TO THE SINGLE DIGITS BY THE
21ST. THE 22ND WAS THE COLDEST DAY OF THE WINTER SEASON SO FAR WITH
A HIGH OF ONLY 9 AND A LOW OF 3 IN SOUTH BEND. LAKE EFFECT SNOWFALL
KICKED IN AND SOUTH BEND RECEIVED OVER 7 INCHES OF SNOW BETWEEN THE
20TH AND 26TH WHILE SOME LOCATIONS IN LOWER MICHIGAN RECEIVED A FOOT
OR MORE.

ANOTHER SIGNIFICANT WARMING TREND BEGAN ON THE 27TH WITH
TEMPERATURES RECOVERING BACK TO NEAR 60 BY THE 29TH. A SECOND ARCTIC
RUSH QUICKLY FOLLOWED AS TEMPERATURES PLUMMETED INTO THE TEENS ON
THE 31ST. RAINFALL OF OVER TWO INCHES FELL AHEAD OF THIS ARCTIC COLD
FRONT AND LAKE EFFECT SNOWFALL OF OVER 4 INCHES FOLLOWED IN ITS
WAKE.

THE AVERAGE MONTHLY TEMPERATURE WAS 27.7 DEGREES...3.3 DEGREES ABOVE
NORMAL. THIS RANKS AS THE 34TH WARMEST JANUARY SINCE 1893. THE
HIGHEST TEMPERATURE FOR THE MONTH WAS 59 ON JANUARY 29TH. THIS WAS
THE WARMEST JANUARY TEMPERATURE SINCE JANUARY 7TH 2008 WHEN THE HIGH
WAS A BALMY 65 DEGREES. THE LOWEST TEMPERATURE WAS 3 ON THE 22ND.
THE LAST TIME SOUTH BEND WAS COLDER THAN THIS WAS ON FEBRUARY 11TH
2011 WHEN THE LOW WAS 2 DEGREES. THE LAST TIME THE TEMPERATURE WAS
BELOW ZERO IN SOUTH BEND WAS FEBRUARY 10TH 2011 WHEN THE LOW WAS
NINE DEGREES BELOW ZERO.

THE MONTHLY PRECIPITATION WAS 5.00 INCHES...2.71 INCHES ABOVE
NORMAL. THE GREATEST 24 HOUR PRECIPITATION WAS ON THE 29TH AND 30TH
WHEN 2.24 INCHES FELL. THE MONTH RANKS AS THE 5TH WETTEST ON RECORD.
THE 1.94 INCHES WHICH FELL ON THE 29TH BROKE A RECORD FOR THE DATE
AND WAS ALSO THE 4TH WETTEST JANUARY DAY ON RECORD. IT WAS ALSO THE
WETTEST JANUARY DAY SINCE 1967 WHEN 2.12 INCHES FELL ON JANUARY
26TH.

SNOWFALL FOR THE MONTH AT SOUTH BEND WAS OFFICIALLY 11.9
INCHES...8.7 INCHES BELOW NORMAL. THIS RANKS AS THE 43RD LOWEST
JANUARY SNOWFALL TOTAL SINCE 1893.


FEBRUARY

...A WET AND SNOWY MONTH WITH NEAR NORMAL TEMPERATURES...

FEBRUARY ENDED A STRING OF MONTHS WITH BELOW NORMAL SNOWFALL THIS
WINTER AT SOUTH BEND. PRECIPITATION WAS ABOVE NORMAL FOR THE THIRD
STRAIGHT MONTH AND TEMPERATURES AVERAGED JUST A LITTLE BELOW NORMAL.

THE WEATHER PATTERN DURING THE MONTH OF FEBRUARY WAS MORE TYPICAL OF
WINTER ACROSS MUCH OF THE UNITED STATES. SEVERAL STRONG WINTER
STORMS IMPACTED THE COUNTRY STARTING WITH A CRIPPLING BLIZZARD AND
HEAVY SNOW OVER THE ATLANTIC SEABOARD AND ENDING WITH TWO POTENT
HEAVY SNOW PRODUCING BLIZZARDS OVER THE CENTRAL UNITED STATES. OUR
LOCAL AREA WAS LEFT IN THE MIDDLE WITH A COMBINATION OF RESIDUAL
SNOWFALL FROM THE MIDWEST STORMS AND MODERATE TO AT TIMES HEAVY LAKE
EFFECT SNOW. SEVERAL WEAKER CLIPPER SYSTEMS ALSO BROUGHT RAIN AND
SNOW TO THE REGION DURING THE MONTH.

WHILE TEMPERATURES OVER THE MONTH AVERAGED NEAR NORMAL...THERE WERE
BRIEF PERIODS OF BITTER COLD AIR AS WELL AS VERY MILD AIR. ON ONE
OCCASION...THE EXCHANGE BETWEEN A COLDER REGIME AND WARMER REGIME
HAPPENED IN JUST ONE DAY. THE HIGH TEMPERATURE ON FEBRUARY 17TH WAS
28 DEGREES AFTER A MORNING LOW OF 11 AND ONE INCH OF SNOWFALL. THE
VERY NEXT DAY SAW A MILD HIGH TEMPERATURE OF 52 DEGREES WITH LIGHT
WINDS AND AMPLE SUNSHINE WHICH MADE IT FELL MUCH WARMER.

THE AVERAGE MONTHLY TEMPERATURE WAS 26.8 DEGREES...0.8 DEGREES BELOW
NORMAL. THE HIGHEST TEMPERATURE WAS 52 ON THE 18TH WHILE THE COLDEST
TEMPERATURE WAS 3 DEGREES ON THE FIRST.

PRECIPITATION FOR FEBRUARY WAS 2.25 INCHES...0.46 INCHES ABOVE
NORMAL. THIS RANKS AS THE 25TH WETTEST FEBRUARY ON RECORD. THE
GREATEST 24 HOUR PRECIPITATION WAS ON THE 26TH WITH 0.52 INCHES
RECORDED. THERE WERE 16 DAYS WITH MEASURABLE PRECIPITATION.

SNOWFALL FOR THE MONTH WAS 24.6 INCHES...10.4 INCHES ABOVE NORMAL.
THIS RANKS AS THE 9TH SNOWIEST FEBRUARY ON RECORD AND THE SECOND
YEAR IN A ROW WHERE FEBRUARY SNOWFALL EXCEEDED 24 INCHES.


MARCH

...WHAT A DIFFERENCE A YEAR MAKES...

MARCH 2013 WAS A COLD MONTH WITH ABOVE NORMAL SNOWFALL AND BELOW
NORMAL PRECIPITATION. THIS WAS A DRASTIC DIFFERENCE FROM MARCH 2012
WHICH SAW NUMEROUS RECORDS FOR WARMTH BROKEN...INCLUDING RECORD HIGH
TEMPERATURES ON NINE CONSECUTIVE DAYS AND NINE CONSECUTIVE DAYS WITH
HIGH TEMPERATURES AT OR ABOVE 70. MARCH 2013 DID NOT SEE A SINGLE
DAY WITH A HIGH TEMPERATURE OF 60 DEGREES. THERE WERE ONLY 5 DAYS
WITH AN AVERAGE TEMPERATURE ABOVE NORMAL AND 15 STRAIGHT DAYS WITH
AN AVERAGE TEMPERATURE BELOW NORMAL.

THE AVERAGE MONTHLY TEMPERATURE THIS MARCH WAS 32.0...5.5 DEGREES
BELOW NORMAL. THIS RANKED AS THE 16TH COLDEST MARCH ON RECORD. IN
CONTRAST...MARCH 2012 WAS THE WARMEST MARCH ON RECORD WITH A MONTHLY
AVERAGE TEMPERATURE OF 52.8 DEGREES. THIS DIFFERENCE OF 20.8 DEGREES
BETWEEN MONTHLY AVERAGE TEMPERATURES IN MARCH 2012 VS 2013 IS THE
GREATEST DIFFERENCE BETWEEN ANY MONTHLY AVERAGE TEMPERATURE FOR THE
SAME MONTH IN CONSECUTIVE YEARS.

THE HIGHEST TEMPERATURE THIS MONTH WAS 59 ON THE 10TH AND 31ST AND
THE COLDEST TEMPERATURE WAS 13 ON THE 8TH. IN MARCH 2012...THE
HIGHEST TEMPERATURE WAS A RECORD 85 DEGREES.

PRECIPITATION FOR THE MONTH WAS JUST 1.26 INCHES...1.16 INCHES BELOW
NORMAL. THIS RANKED AS THE 13TH DRIEST MARCH ON RECORD.
IRONICALLY...MORE PRECIPITATION FELL IN MARCH 2012...1.67 INCHES...
WHEN IT WAS WARMER AND CONSIDERED BY MANY TO BE MORE PLEASANT
COMPARED TO THIS MARCH. MEASURABLE PRECIPITATION THIS MONTH WAS
RECORDED ON 12 DAYS WHILE A TRACE OR MORE WAS RECORDED ON 22 DAYS.
DESPITE 70 PERCENT OF THE DAYS HAVING SOME FORM OF
PRECIPITATION...ONLY 2 DAYS HAD A TENTH OR MORE. THE HIGHEST DAILY
PRECIPITATION TOTAL WAS 0.72 INCHES ON THE 5TH.

EVEN THOUGH PRECIPITATION WAS BELOW NORMAL...SNOWFALL WAS ABOVE
NORMAL THIS MONTH. A TOTAL OF 12.2 INCHES WAS RECORDED...5.1 INCHES
ABOVE NORMAL. THIS RANKED AS THE 29TH SNOWIEST MARCH.

APRIL

...VERY WET MONTH WITH BELOW NORMAL TEMPERATURES...

APRIL 2013 WAS A COLD MONTH WITH MUCH ABOVE NORMAL PRECIPITATION AND
BELOW NORMAL SNOWFALL ACROSS THE AREA. AFTER A SNOWY MARCH...APRIL
WAS CHARACTERIZED BY MORE TYPICAL SPRING-LIKE WEATHER SYSTEMS
THAT CAUSED DRASTIC SWINGS IN TEMPERATURES AND SEVERAL ROUNDS OF
HEAVY RAINFALL. THIS HEAVY RAINFALL LED TO WIDESPREAD FLOODING OF
RIVERS AND LOW LYING AREAS DURING THE LAST HALF OF THE MONTH AND
ERADICATED ANY REMAINING ABNORMALLY DRY AREAS ON THE US DROUGHT
MONITOR.

THE AVERAGE MONTHLY TEMPERATURE AT SOUTH BEND FOR APRIL WAS 46.8
DEGREES...2.2 DEGREES BELOW NORMAL. THIS RANKED AS THE 31ST COLDEST
APRIL ON RECORD. THE HIGHEST TEMPERATURE THIS MONTH WAS 81 ON THE
30TH AND THE COLDEST TEMPERATURE WAS 18 ON THE 3RD.

MORE WAS RECORDED ON 20 DAYS. THE HIGHEST DAILY PRECIPITATION TOTAL
WAS 1.39 INCHES ON THE 10TH-11TH.

ONLY A TRACE OF SNOWFALL WAS RECORDED AT SOUTH BEND FOR THE MONTH OF
APRIL. THIS WAS 1.4 INCHES BELOW NORMAL. A TRACE OF SNOWFALL WAS
ACTUALLY RECORDED ON 5 DAYS.


MAY

...A DRY BEGINNING BUT A WET ENDING TO MAY...

MAY BEGAN WARM AND VERY DRY AFTER A COOL AND WET APRIL. JUST A
QUARTER OF AN INCH OF RAIN FELL BETWEEN THE FIRST AND THE 20TH OF
MAY BUT NEARLY THREE INCHES OF RAIN FELL BETWEEN THE 21ST AND 31ST.
THERE WAS ALSO A LACK OF SEVERE WEATHER THROUGHOUT THE
MONTH...HOWEVER A SERIES OF THUNDERSTORM COMPLEXES OVER THE LAST
THREE DAYS OF THE MONTH BROUGHT DAMAGING WINDS AND FLASH FLOODING TO
PORTIONS OF THE REGION.

HIGH TEMPERATURES WERE ABOVE 70 DEGREES DURING THE FIRST
NINE DAYS OF THE MONTH AND HIGHS WERE AT OR ABOVE 70 ON 23 DAYS
DURING THE MONTH. DESPITE BEING A RELATIVELY WARM MONTH...THERE WAS
A LARGE CONTRAST IN TEMPERATURES. THE WARMEST HIGH TEMPERATURE WAS
90 ON THE 20TH WHILE THE COOLEST HIGH TEMPERATURE WAS JUST 50
DEGREES ON THE 12TH. THERE WAS A LOW TEMPERATURE RECORD TIED AS
WELL. THE LOW ON MAY 13TH WAS 30 DEGREES...TYING THE OLD RECORD SET
IN 1996 AND 1928. ON MAY 21ST...A RECORD WARM LOW TEMPERATURE OF 70
DEGREES OCCURRED...TYING THE OLD RECORD SET IN 1911.

THE AVERAGE MONTHLY TEMPERATURE FOR MAY WAS 62.9 DEGREES...3.6
DEGREES ABOVE NORMAL. THIS RANKS AS THE T-21ST WARMEST MAY ON
RECORD. PRECIPITATION FOR THE MONTH WAS 3.25 INCHES...0.58 INCHES
BELOW NORMAL. THIS RANKS AS THE 58TH DRIEST MAY ON RECORD.

JUNE

...TYPICAL JUNE WEATHER AT SOUTH BEND...

WHAT A DIFFERENCE A YEAR MAKES! AT THIS TIME IN JUNE 2012...THE AREA
WAS SUFFERING FROM AN EXTENSIVE DROUGHT WITH A HEAT WAVE THAT SAW
TEMPERATURES HIT THE TRIPLE DIGIT MARK. THIS JUNE STARTED WITH
COOLER TEMPERATURES AND BELOW NORMAL RAINFALL AND ENDED WITH A WEEK
OF ABOVE NORMAL TEMPERATURES AND SEVERAL ROUNDS OF SEVERE WEATHER
AND HEAVY RAINFALL.

THE AVERAGE MONTHLY TEMPERATURE FOR JUNE WAS 69.0 DEGREES...0.1
DEGREES BELOW NORMAL. THIS RANKED AS THE 53RD COLDEST JUNE ON
RECORD. THE HIGHEST TEMPERATURE THIS MONTH WAS 89 ON THE 12TH. THIS
MARKED THE FIRST JUNE WITHOUT A 90 DEGREE DAY SINCE JUNE 1993. THIS
WAS ALSO IN CONTRAST FROM JUNE 2012 WHICH SAW 9 90 DEGREE DAYS! THE
COLDEST TEMPERATURE WAS 39 ON THE 3RD.

PRECIPITATION FOR THE MONTH WAS 3.43 INCHES...0.36 INCHES BELOW
NORMAL. THIS DOES NOT RANK IN THE TOP 50 WETTEST OR DRIEST JUNES ON
RECORD. MEASURABLE PRECIPITATION THIS MONTH WAS RECORDED ON 15 DAYS
WHILE A TRACE OR MORE WAS RECORDED ON 18 DAYS. NO DAY SAW AN INCH OF
PRECIPITATION OR MORE THIS MONTH WITH THE HIGHEST DAILY

JULY

...A RELATIVELY COOL JULY WITH BELOW NORMAL RAINFALL AT SOUTH BEND...

THE HEAT WAVE BEGAN AROUND JULY 14TH AND ENDED ON THE 19TH. THERE
WERE 4 DAYS OF TEMPERATURES AT OR ABOVE 90 WITH THE HOTTEST
TEMPERATURE OF 94 OCCURRING ON THE 19TH. THE LOW TEMPERATURE ON THIS
DAY ONLY DROPPED TO 76 DEGREES. THE AVERAGE TEMPERATURE ON THIS DAY
WAS 85...MAKING IT THE HOTTEST DAY OF THE YEAR SO FAR. IT WAS ALSO A
VERY MUGGY PERIOD AS DEW POINTS WERE GENERALLY IN THE LOWER TO
MIDDLE 70S. THIS ALLOWED HEAT INDICES TO CLIMB INTO THE UPPER 90S
AND LOWER 100S.

THE AVERAGE MONTHLY TEMPERATURE AT SOUTH BEND WAS 71.8 WHICH WAS 1.2
DEGREES BELOW NORMAL. THIS RANKED AS THE 38TH COOLEST JULY ON

AUGUST

...RELATIVELY COOL AND DRY IN AUGUST AT SOUTH BEND...

ALTHOUGH AUGUST ENDED WITH A STRETCH OF WARMER WEATHER...THE MONTH

DAY...SEPTEMBER 19TH. THERE WERE 10 DAYS WITH BELOW NORMAL
TEMPERATURES AND JUST ONE DAY WITH AN AVERAGE TEMPERATURE OF MORE
THAN 9 DEGREES BELOW NORMAL...SEPTEMBER 14TH. THERE WAS ONE VERY
WARM STRETCH WHICH HELPED BOOST THE AVERAGE MONTHLY TEMPERATURE TO

OCTOBER 2013 HAD A VERY WARM START AT SOUTH BEND...WITH THE FIRST 5
DAYS OF THE MONTH HAVING AN AVERAGE TEMPERATURE OF 11 DEGREES OR
MORE ABOVE NORMAL. AFTER NEAR NORMAL TEMPERATURES THROUGH THE MIDDLE
PART OF THE MONTH...A PATTERN SHIFT BROUGHT WELL BELOW NORMAL
TEMPERATURES TO THE REGION BEGINNING ON THE 22ND. THIS HELPED
TRIGGER LAKE EFFECT MIXED PRECIPITATION OVER A FOUR DAY PERIOD...WITH
SOME AREAS ACROSS MICHIANA RECEIVING THEIR FIRST ACCUMULATING
SNOWFALL OF THE SEASON.

AN INTERESTING STATISTIC FROM THIS WILD SWING IN TEMPERATURES: THERE
WERE ONLY 18 DAYS BETWEEN 80 DEGREE TEMPERATURES AND FREEZING

WHICH FELL ON THE 30TH AND 31ST.


NOVEMBER

...A COLD AND SNOWY NOVEMBER...

OVERALL NOVEMBER WAS COLDER THAN NORMAL WITH BELOW NORMAL
PRECIPITATION BUT ABOVE NORMAL SNOWFALL. MOST OF THE SNOWFALL WAS
ATTRIBUTED TO LAKE EFFECT SNOW...WITH THE HEAVIEST AMOUNTS
FALLING ON THE 26TH AND 27TH AT THE OFFICIAL REPORTING SITE IN SOUTH
BEND. THIS EVENT PRODUCED 12 TO 16 INCHES OF SNOW ACROSS BERRIEN
