SPRING SEASON SUMMARY

...A WET AND COLD SPRING BUT BELOW NORMAL SNOWFALL...

THE SPRING CONTINUED A TREND OF FREQUENT PRECIPITATION THAT GOES ALL
THE WAY BACK TO THE WINTER MONTHS. THE LONGEST STRETCH OF DAYS
WITHOUT ANY PRECIPITATION WAS JUST TWO DAYS ON SEVERAL OCCASIONS.
WHAT IS INCREDIBLE STATISTICALLY IS THAT THE LAST TIME A STRING OF
MORE THAN TWO DAYS IN A ROW OCCURRED WITHOUT ANY PRECIPITATION AT
ALL WAS JANUARY 3RD THROUGH THE 6TH. THAT IS NEARLY 5 MONTHS IN A
ROW OR 150 DAYS!

THE AVERAGE MONTHLY TEMPERATURE FOR THE 2019 SPRING SEASON WAS 46.0
DEGREES, 2.6 DEGREES BELOW NORMAL. THIS RANKED AS THE 20TH COLDEST
SPRING SEASON. THE WARMEST TEMPERATURE WAS 85 ON MAY 18TH AND THE
COLDEST TEMPERATURE WAS 2 DEGREES ON MARCH 4TH.

SPRING PRECIPITATION WAS 14.94 INCHES, 5.46 INCHES ABOVE NORMAL.
THIS RANKED AS THE 5TH WETTEST SPRING SEASON ON RECORD. THIS WAS THE
WETTEST SPRING SINCE 2011 WHEN 17.10 INCHES OF PRECIPITATION WAS
RECORDED. MEASUREABLE PRECIPITATION OCCURRED ON 45 DAYS, WHICH IS
ABOUT 7 DAYS ABOVE NORMAL FOR THE SEASON.

SPRING SNOWFALL WAS JUST 1.5 INCHES, 7.0 INCHES BELOW NORMAL. THIS
RANKED AS THE 8TH LEAST SNOWIEST WINTER SEASON.

THE TOTAL SEASONAL SNOWFALL FOR THE PERIOD OCTOBER 1ST TO MAY 31ST
WAS 45.7 INCHES, 20.9 INCHES BELOW NORMAL. THIS WAS THE 35TH LEAST
SNOWIEST SEASONAL SNOWFALL ON RECORD. THE SNOWIEST WAS 1977-78 WITH
172 INCHES.

BELOW IS THE MONTH BY MONTH SUMMARY OF THE 2019 SPRING SEASON.

MARCH

...A VERY COOL MARCH, AND WE DON`T MEAN IT WAS POPULAR...

MARCH BEGAN WITH VERY CHILLY TEMPERATURES AND SOME SNOW DURING THE
FIRST WEEK, AND IT ENDED VERY MUCH THE SAME WAY. AVERAGE DAILY
TEMPERATURES WERE BETWEEN 10 AND 25 DEGREES BELOW NORMAL FROM THE
3RD TO THE 7TH WITH LIGHT SNOW AT TIMES. A RECORD COLD MAXIMUM
TEMPERATURE OCCURRED ON BOTH MARCH 4TH AND 5TH WITH A HIGH OF ONLY
14 AND 19 DEGREES RESPECTIVELY. THE PERIOD OF MARCH 1ST THROUGH
MARCH 7TH WAS THE 7TH COLDEST ON RECORD FOR THIS STRETCH OF DAYS.

WHILE THE REMAINDER OF MARCH WOULD REMAIN COLD, DAILY AVERAGE
TEMPERATURE DEPARTURES FROM NORMAL WOULD NOT REACH MORE THAN 7
DEGREES BELOW NORMAL UNTIL THE FINAL DAY OF THE MONTH, WHICH WAS 16
DEGREES BELOW NORMAL. A TOTAL OF 23 OUT OF 31 DAYS EXPERIENCED BELOW
NORMAL AVERAGE TEMPERATURES.

THE AVERAGE MONTHLY TEMPERATURE FOR MARCH WAS 33.0 DEGREES, 4.5
DEGREES BELOW NORMAL. THIS RANKED AS THE 29TH COLDEST MARCH ON
RECORD. THE HIGHEST TEMPERATURE WAS 67 ON THE 14TH AND THE COLDEST
WAS 2 DEGREES ON THE 4TH. THERE WERE 25 DAYS WITH A MINIMUM
TEMPERATURE 32 DEGREES OR COLDER. THIS IS ABOUT 5 DAYS GREATER THAN
NORMAL FOR MARCH. THERE WERE ALSO 6 DAYS WITH A MAXIMUM TEMPERATURE
OF 32 DEGREES OR COLDER AND THIS WAS ABOUT 3 DAYS GREATER THAN
NORMAL.

PRECIPITATION FOR MARCH WAS SLIGHTLY ABOVE NORMAL WITH 2.84 INCHES,
0.42 INCHES ABOVE NORMAL. THIS RANKED AS THE 49TH WETTEST MARCH ON
RECORD. MEASURABLE PRECIPITATION FELL ON 12 DAYS.

SNOWFALL WAS WELL BELOW NORMAL WITH 0.5 INCHES, 6.6 INCHES BELOW
NORMAL. THIS WAS THE 10TH LEAST SNOWIEST MARCH ON RECORD. THE 0.5
INCH MONTHLY SNOWFALL TOTAL IS ACTUALLY THE 3RD LEAST AMOUNT EVER
MEASURED IN MARCH (6 OF THE PREVIOUS RECORD YEARS SAW JUST A TRACE
MEASURED AND 3 OF THE YEARS HAD JUST 0.1 INCH FOR THE MONTHLY
TOTALS).

APRIL

...A SOAKING END...

APRIL 2019 WAS A ROLLER-COASTER MONTH WHERE IT WAS DRY TO START,
SIGNIFICANTLY WET TO END, WITH TEMPERATURE SWINGS BOTH ABOVE AND
BELOW NORMAL. IT SEEMED AS IF SPRING WERE HERE TO STAY FROM THE 5TH
THROUGH THE 9TH WHEN THE AVERAGE TEMPERATURE DEPARTURE FOR THOSE
DAYS REACHED AS HIGH AS 14.3 DEGREES ABOVE NORMAL ON THE 8TH. THIS
WAS FOLLOWED BY SIX DAYS OF BELOW NORMAL TEMPERATURES, WITH A
DEPARTURE AS GREAT AS 12.6 DEGREES BELOW NORMAL ON THE 14TH. IN THE
FINAL FIVE DAYS OF APRIL, 2.94 INCHES OF PRECIPITATION WAS REPORTED.
IN THAT SAME STRETCH, THE AVERAGE DAILY TEMPERATURE WAS AS MUCH AS
15.8 DEGREES BELOW NORMAL ON THE 27TH.

THE AVERAGE TEMPERATURE FOR THE MONTH WAS 48.0 DEGREES, WHICH IS 1.0
DEGREE BELOW NORMAL. THIS RANKS AS THE 52ND COLDEST APRIL. 17 OF 30
DAYS OBSERVED AN AVERAGE DAILY TEMPERATURE BELOW NORMAL. THE COLDEST
TEMPERATURE THIS MONTH WAS A LOW OF 19 DEGREES ON THE 1ST. THE
WARMEST TEMPERATURE WAS 76 DEGREES ON THE 22ND.

4.88 INCHES OF PRECIPITATION WAS OBSERVED WHICH IS 1.65 INCHES ABOVE
NORMAL. THIS RANKS AS THE 25TH WETTEST APRIL. MEASURABLE
PRECIPITATION OCCURRED ON 11 OF 30 DAYS, WITH FIVE OF THESE DAYS
RECEIVING AT LEAST 0.50 INCHES OF PRECIPITATION. TOTAL PRECIPITATION
 FOR THE MONTH WAS BELOW NORMAL AS LATE AS THE 28TH, WHEN IT WAS
0.37 INCHES BELOW NORMAL. THEN, ON THE FINAL TWO DAYS OF THE MONTH,
2.25 INCHES OF PRECIPITATION WAS OBSERVED.

1.0 INCH OF SNOW WAS RECORDED FOR THE MONTH WHICH IS 0.4 INCHES
BELOW NORMAL. MEASUREABLE SNOW OCCURRED ON TWO DAYS; 0.8 INCHES ON
THE 27TH AND 0.2 INCHES ON THE 14TH. BARRING ANY MAY SNOWFALL, THIS
RANKS AS THE 7TH LATEST SNOWFALL ON RECORD.

ONE RECORD WAS TIED THIS MONTH. ON THE 28TH, A TRACE OF SNOW WAS
RECORDED WHICH TIES THE PREVIOUS RECORD SET IN 2011.

MAY

...MAYDAY, MAYDAY, MAY DAYS BRING RAIN AND COOL TEMPERATURES...

WHO WILL STOP THE RAIN? WE DON`T KNOW THAT ANSWER BUT WHAT WE DO
KNOW IS THAT MAY 2019 WILL BE REMEMBERED AS A COOL AND VERY WET
MONTH WITH OVER 7 INCHES OF RAINFALL AROUND THE SOUTH BEND AREA.
WHAT IS SURPRISING IS THAT MAY 2019 WAS NOT EVEN AS WET AS MAY 2018,
WHICH WAS THE WETTEST MAY ON RECORD WITH 8.33 INCHES. THE DIFFERENCE
THOUGH IS THAT THE RAIN THIS YEAR WAS SPREAD OVER THE ENTIRE MONTH
WITH ONLY ONE SMALL STRETCH OF CONSECUTIVE DRY DAYS. IN FACT, THE
TOP 4 WETTEST MONTHS OF MAY ON RECORD HAVE ALL OCCURRED SINCE 1996.

THE ONLY TWO DAYS IN A ROW IN WHICH NO RAINFALL AT ALL WAS RECORDED
WAS ON MAY 14TH AND 15TH. THERE WAS A STRETCH OF FOUR DAYS IN A ROW
WITH NO MEASURABLE PRECIPITATION, MAY 3RD THROUGH THE 6TH, BUT A
TRACE OF RAIN (LESS THAN 0.01 INCHES) OCCURRED ON THE 4TH AND 6TH.
MAY IS NORMALLY THE SECOND WETTEST MONTH OF THE YEAR WITH 3.83
INCHES OF RAIN. THIS YEAR, THAT AMOUNT WAS ALMOST DOUBLED AND
MEASURABLE RAIN FELL ON 22 DAYS.

WITH RAIN ON MOST DAYS THIS MONTH, A LOT OF CLOUDS HELPED KEEP
TEMPERATURES ON THE COOL SIDE. SURPRISINGLY, IT WAS NOT A
SIGNIFICANTLY COLD MONTH AS SEVERAL DAYS THAT SAW THUNDERSTORMS ALSO
HAD WARM TEMPERATURES BEFORE THEY DEVELOPED. THIS HELPED RAISE THE
MONTHLY AVERAGE TEMPERATURE.

MAY 2019 RANKED AS THE 40TH COOLEST ON RECORD WITH AN AVERAGE
TEMPERATURE OF 57.2 DEGREES, 2.1 DEGREES BELOW NORMAL. THE WARMEST
TEMPERATURE WAS 85 ON THE 18TH AND THE COLDEST WAS 34 ON THE 14TH.
THERE WERE 20 DAYS DURING THE MONTH WITH AN AVERAGE TEMPERATURES AT
OR BELOW NORMAL.

TOTAL PRECIPITATION FOR MAY WAS 7.22 INCHES, 3.39 INCHES ABOVE
NORMAL. THIS RANKED AS THE 4TH WETTEST MAY ON RECORD. THE GREATEST
24 HOUR RAINFALL WAS 1.77 INCHES ON THE 27TH. THIS WAS A SINGLE DAY
RECORD FOR THAT DATE.
