...A MILD AND WET SPRING WITH ABOVE NORMAL SNOWFALL...

THE AVERAGE TEMPERATURE FOR SPRING 2016 AT SOUTH BEND WAS 49.5
DEGREES...0.9 DEGREES ABOVE NORMAL. THIS RANKED AS THE 31ST WARMEST
SPRING ON RECORD AND NEARLY IDENTICAL TO THE AVERAGE SPRING
TEMPERATURE LAST YEAR.

SPRING PRECIPITATION WAS 11.33 INCHES...1.85 INCHES ABOVE NORMAL.
THIS RANKED AS THE 39TH WETTEST SPRING ON RECORD.

SNOWFALL DURING THE SPRING WAS 10.9 INCHES...2.4 INCHES ABOVE
NORMAL. THIS RANKED AS THE 51ST SNOWIEST SPRING ON RECORD.

BELOW IS A MONTH BY MONTH REVIEW OF THE SPRING 2016 SEASON.


...A WARM AND WET MARCH...

THE FIRST MONTH OF SPRING CAME IN LIKE A LION WITH COLD AND SNOW BUT
ENDED WITH MILD TEMPERATURES AND SCATTERED STRONG TO SEVERE
THUNDERSTORMS.

STRONG LOW PRESSURE TRACKED THROUGH CENTRAL AND NORTHEAST INDIANA ON
THE FIRST OF THE MONTH. RAIN CHANGED TO SNOW IN THE WAKE OF THIS LOW
WITH SEVERAL INCHES OF ACCUMULATION ACROSS THE AREA...MUCH OF IT
FROM LAKE EFFECT SNOW.  ANOTHER LOW PRESSURE SYSTEM MOVED THROUGH
THE OHIO VALLEY ON THE THIRD AND THIS SYSTEM BROUGHT ANOTHER ROUND
OF ACCUMULATING SNOW. THESE WEATHER SYSTEMS AND THE SNOWPACK THEY
PRODUCED HELPED TO DROP LOW TEMPERATURES INTO THE TEENS AND SINGLE
DIGITS DURING THE FIRST 4 DAYS OF MARCH.

A SIGNIFICANT PATTERN CHANGE OCCURRED AFTER THE FOURTH WITH MUCH
WARMER TEMPERATURES WHICH HELPED TO QUICKLY MELT THE SNOW. THE
WARMUP WAS SO DRAMATIC THAT HIGH TEMPERATURES REACHED THE 60S BY THE
7TH AND 70S ON THE 8TH. THE AVERAGE DAILY TEMPERATURE WENT FROM 11
DEGREES BELOW NORMAL ON THE 4TH TO 18 DEGREES ABOVE NORMAL ON THE
7TH AND 29 DEGREES ABOVE NORMAL ON THE 8TH. THE ABOVE NORMAL
TEMPERATURES CONTINUED THROUGH THE 17TH BEFORE A COLD FRONT BROUGHT
TEMPERATURES BACK TO NEAR OR SLIGHTLY BELOW NORMAL. THE REMAINDER OF
THE MONTH WOULD SEE SWINGS IN TEMPERATURES AS SEVERAL WEATHER
SYSTEMS WOULD MOVE THROUGH THE REGION.

AN ACTIVE WEATHER PATTERN OVER THE LAST WEEK OF MARCH HELPED KICK
OFF THE SEVERE WEATHER SEASON. SEVERE THUNDERSTORMS AND THE FIRST
THREE TORNADOES OF THE YEAR OCCURRED ON MARCH 24TH. DAMAGE
ASSOCIATED WITH WEAK EF0 TORNADOES WERE FOUND IN EDWARDSBURG
MICHIGAN...AS WELL AS NEAR HANNA AND WANATAH INDIANA. SEVERE
THUNDERSTORMS ALSO DEVELOPED AGAIN ON THE 27TH WITH LARGE HAIL THE
SIZE OF GOLF BALLS BEING REPORTED OVER MAINLY NORTHEAST INDIANA. THE
LAST DAY OF MARCH ALSO SAW ISOLATED SEVERE WEATHER WITH WIND AND
HAIL.

THE AVERAGE MONTHLY TEMPERATURE FOR MARCH WAS 42.5 DEGREES...5.0
DEGREES ABOVE NORMAL. THIS RANKED AS THE 17TH WARMEST MARCH ON
RECORD. THE WARMEST TEMPERATURE WAS 71 ON THE 8TH AND THE COLDEST
WAS 8 ON THE 4TH.

PRECIPITATION WAS WELL ABOVE NORMAL WITH 4.17 INCHES WHICH WAS 1.75
INCHES ABOVE NORMAL. THIS RANKED AS THE 14TH WETTEST MARCH ON
RECORD. THERE WERE 12 DAYS OF MEASURABLE PRECIPITATION AND 3 DAYS
HAD OVER A HALF INCH OF PRECIPITATION.

SNOWFALL FOR THE MONTH WAS 6.8 INCHES...0.3 INCHES BELOW NORMAL.
THIS RANKED AS THE 62ND LEAST SNOWIEST MARCH ON RECORD. ALL OF THE
MEASURABLE SNOW FELL ON THE FIRST...SECOND...THIRD AND FIFTH OF THE
MONTH.

...A COOLER AND WETTER THAN NORMAL APRIL AT SOUTH BEND...

APRIL STARTED OUT RATHER COOL ACROSS SOUTH BEND AND THE MICHIANA
REGION...WITH THE AVERAGE TEMPERATURE BELOW NORMAL FOR THE FIRST 13
DAYS OF THE MONTH. THE COLDEST NIGHTS INTO THE EARLY MORNING HOURS
OF THE 3RD AND 4TH SAW TEMPERATURE DIP DOWN TO 22 AND 18
RESPECTIVELY AT SOUTH BEND. FORTUNATELY...THE GROWING SEASON IN
GENERAL HAD YET TO COMMENCE BEFORE THIS COLD STRETCH OF WEATHER. A
LAST GASP OF SNOW ON THE 8TH...9TH AND 10TH CAPPED OFF THIS COLD
STRETCH.

A PATTERN FLIP OCCURRED AROUND THE MIDDLE OF THE MONTH. AFTER AT
LEAST A TRACE OF PRECIPITATION EACH OF THE FIRST 11 DAYS OF THE
MONTH...DRY CONDITIONS PREVAILED FROM THE 12TH THROUGH THE 19TH. A
WARMING TREND CULMINATED IN HIGH TEMPERATURES IN THE 80S ON THE 17TH
AND 18TH. THIS WAS THE FIRST 80 DEGREE TEMPS OF THE YEAR...ABOUT 9
DAYS BEFORE THE LONG TERM AVERAGE FIRST 80 DEGREE DAY OF THE
YEAR...APRIL 26TH. IT WAS THE EARLIEST 80 DEGREE DAY IN THE YEAR
SINCE 2012...WHEN IT FIRST HIT 80 ON MARCH 14TH. BUT IT WAS ONLY 1
DAY EARLIER THAN THE FIRST 80 DEGREE MARK LAST YEAR...APRIL 18TH
2015.

AFTER AN UP AND DOWN...WET AND DRY PATTERN FROM THE 21ST TO THE
26TH...THE MONTH ENDED ON A COOLER NOTE WITH THE LAST 4 DAYS OF THE
MONTH EXPERIENCING BELOW NORMAL AVERAGE TEMPERATURES. A TRACE OF
PRECIPITATION WAS RECORDED 5 OUT OF THE LAST 6 DAYS OF THE MONTH.

THE AVERAGE MONTHLY TEMPERATURE FOR APRIL WAS 47.5 DEGREES...1.5
DEGREES BELOW NORMAL. THIS RANKED AS THE 45TH COLDEST APRIL ON
RECORD. THE WARMEST TEMPERATURE WAS 82 ON THE 18TH AND THE COLDEST
WAS 18 ON THE 5TH.

PRECIPITATION WAS ABOVE NORMAL FOR THE SECOND CONSECUTIVE MONTH WITH
4.67 INCHES...WHICH WAS 1.44 INCHES ABOVE NORMAL. THIS RANKED AS THE
27TH WETTEST APRIL ON RECORD. THERE WERE 15 DAYS OF MEASURABLE
PRECIPITATION AND 9 DAYS WITH OVER A TENTH OF AN INCH OF
PRECIPITATION. 2 DAYS...THE 6TH AND THE 21ST... HAD OVER AN INCH OF
PRECIPITATION. THE GREATEST 24 HOUR PRECIPITATION TOTAL WAS 1.25
INCHES FALLING ON THE 6TH AND 7TH OF THE MONTH.

SNOWFALL FOR THE MONTH WAS 4.1 INCHES...2.7 INCHES ABOVE NORMAL.
THIS RANKED AS THE 19TH SNOWIEST APRIL ON RECORD AT SOUTH BEND. ALL
OF THE MEASURABLE SNOW FELL ON THE SECOND...EIGHTH...NINTH AND TENTH
OF THE MONTH.

OVERALL THE MONTH OF MAY WAS COOLER AND DRIER THAN NORMAL IN THE
SOUTH BEND AREA. THE MONTH BEGAN COOL AND WET BUT TRENDED WARM AND
DRY DURING THE LAST 10 DAYS.

DURING THE FIRST 23 DAYS OF MAY...ONLY TWO DAYS HAD AN AVERAGE DAILY
TEMPERATURE ABOVE NORMAL. THE LAST 8 DAYS OF THE MONTH WERE ALL
ABOVE NORMAL AND 5 OF THESE DAYS WERE MORE THAN 10 DEGREES ABOVE
NORMAL. THIS HELPED BRING THE MONTHLY TEMPERATURE DEPARTURE UP
CLOSER TO NORMAL DESPITE THE VERY COOL FIRST THREE WEEKS.

MEASURABLE PRECIPITATION FELL ON 13 DAYS IN MAY BUT ONLY 4 OF THESE
DAYS WERE AFTER THE 14TH. THE GREATEST PRECIPITATION FELL ON THE 4TH
WITH 0.84 INCHES BEING RECORDED.
