BELOW IS A MONTH BY MONTH SUMMARY OF THE SPRING SEASON.


...SEASONABLE TEMPERATURES WITH ABOVE NORMAL RAINFALL IN MARCH...

THE AVERAGE TEMPERATURE FOR MARCH WAS CLOSE TO NORMAL AT SOUTH BEND
INTERNATIONAL AIRPORT WHILE PRECIPITATION WAS ABOVE NORMAL.
TEMPERATURES VARIED SIGNIFICANTLY DURING THE MONTH...BUT AFTER A
VERY WARM FEBRUARY...MARCH FELT COLDER THAN NORMAL TO MANY PEOPLE.
THE MONTH BEGAN WITH SEVERE THUNDERSTORMS AND TEMPERATURES IN THE
50S BUT BY THE 3RD HIGHS WERE ONLY IN THE 20S AND LOWS WERE IN THE
TEENS AND LOWER 20S ACROSS THE REGION. TEMPERATURES WOULD WARM AGAIN
THOUGH WITH HIGHS BACK CLOSE TO 60 BY THE 5TH. THE REMAINDER OF THE
MONTH WOULD SEE SIMILAR SWINGS FROM WARM TO COLD. THE BIGGEST CHANGE
OCCURRED ON THE 23RD AND 24TH WHEN THE HIGH TEMPERATURE WENT FROM 48
ON THE 23RD TO 78 ON THE 24TH. 2 OF THE FINAL 6 DAYS OF MARCH
CONTAINED STRONG THUNDERSTORMS WITH PRECIPITATION TOTALS REACHING
HIGHER THAN 0.75 INCH OF RAIN EACH DAY.

THE AVERAGE MONTHLY TEMPERATURE WAS 36.9 DEGREES...0.6 DEGREES BELOW
NORMAL. THIS RANKED AS THE 68TH COOLEST MARCH ON RECORD. THERE WAS
4.23 INCHES OF PRECIPITATION...1.81 INCHES ABOVE NORMAL. THIS RANKED
AS THE 14TH WETTEST MARCH ON RECORD. SNOWFALL FOR MARCH WAS 7.9
INCHES...0.8 INCHES ABOVE NORMAL. THIS RANKED AS THE 56TH SNOWIEST
MARCH ON RECORD.

...MILD APRIL WITH NEAR NORMAL PRECIPITATION...

TEMPERATURES AVERAGED ABOVE NORMAL FOR THE MONTH AT SOUTH BEND WHILE
PRECIPITATION WAS NEAR NORMAL THANKS TO JUST OVER ONE HALF INCH OF
RAINFALL ON THE LAST DAY OF THE MONTH. THERE WAS ONE DAY WITH
MEASURABLE SNOW ON APRIL 6TH BUT THE MONTHLY TOTAL WAS BELOW NORMAL.

IT WAS A RATHER TYPICAL APRIL WITH LARGE VARIATIONS IN TEMPERATURES.
DAILY HIGH TEMPERATURES RANGED FROM THE LOWER 40S TO THE LOWER 80S
WHILE DAILY LOW TEMPERATURES RANGED FROM THE UPPER 20S TO THE LOWER
60S. THE WARMEST TEMPERATURE FOR THE MONTH WAS 82 ON THE 26TH AND
THE COLDEST TEMPERATURE WAS 27 ON THE 8TH.

THE AVERAGE MONTHLY TEMPERATURE WAS 52.2...3.2 DEGREES ABOVE NORMAL.
THIS RANKED AS THE 15TH WARMEST APRIL ON RECORD. THERE WERE 12 DAYS
WITH AN AVERAGE TEMPERATURE BELOW NORMAL BUT THERE WERE NO DAYS WITH
AN AVERAGE TEMPERATURE MORE THAN 9 DEGREES BELOW NORMAL. IN
CONTRAST...THERE WERE 7 DAYS WITH AN AVERAGE TEMPERATURE OF AT LEAST
10 DEGREES OR MORE ABOVE NORMAL.

TOTAL PRECIPITATION FOR THE MONTH WAS 3.09 INCHES...0.14 INCHES
BELOW NORMAL. THIS RANKED AS THE 60TH DRIEST APRIL ON RECORD.
MEASURABLE PRECIPITATION FELL ON 14 DAYS.

THERE WAS 0.6 INCHES OF SNOW...ALL FALLING ON APRIL 6TH. THIS WAS
0.8 INCHES BELOW THE NORMAL OF 1.4 INCHES AND RANKED AS THE 51ST
LEAST SNOWIEST APRIL ON RECORD.

...A COOL AND WET MAY...

METEOROLOGICAL SPRING CAME TO AN END WITH A RATHER COOL AND WET MAY.
MEASURABLE PRECIPITATION FELL ON NEARLY HALF OF THE DAYS IN THE
MONTH AND TEMPERATURES WERE BELOW NORMAL ON 19 DAYS. THE AVERAGE
DAILY TEMPERATURE WAS AT OR BELOW NORMAL FOR THE FIRST 9 DAYS AND 6
OF THESE DAYS WERE 10 DEGREES OR MORE BELOW NORMAL. THERE WAS A NICE
STRETCH OF WEATHER FROM AROUND THE 14TH THROUGH THE 18TH WITH ABOVE
NORMAL TEMPERATURES AND NO PRECIPITATION. THIS BRIEF WINDOW DID
ALLOW MANY FARM FIELDS TO DRY OUT WHICH GAVE FARMERS A CHANCE TO GET
THEIR SPRING CROPS IN. UNFORTUNATELY THIS WINDOW CAME TO A QUICK
CLOSE AS MORE RAIN RETURNED WITH OVER AN INCH FALLING ON THE 19TH
AND 20TH COMBINED.

THE AVERAGE MONTHLY TEMPERATURE WAS 56.8...2.5 DEGREES BELOW NORMAL.
THIS RANKED AS THE 35TH COOLEST MAY ON RECORD. THE HIGHEST
TEMPERATURE WAS 85 ON THE 16TH AND 18TH AND THE COOLEST TEMPERATURE
WAS 28 ON THE 8TH. THERE WERE 3 DAYS DURING THE MONTH WITH A LOW
TEMPERATURE BELOW FREEZING.

MONTHLY PRECIPITATION WAS 4.92 INCHES...1.09 INCHES ABOVE NORMAL.
THIS RANKED AS THE 33RD WETTEST MAY ON RECORD. MEASURABLE
PRECIPITATION FELL ON 13 DAYS AND A HALF INCH OR MORE OF RAIN FELL
ON 4 DIFFERENT DAYS.
