A COLD AND DRY BEGINNING TO THE SPRING SEASON ENDED WITH WARMTH AND
WETTER CONDITIONS AT SOUTH BEND

...MARCH WAS A COLD START TO SPRING...

MARCH WAS ANOTHER VERY COLD MONTH ACROSS THE GREAT LAKES REGION
DESPITE THE BEGINNING OF SPRING ON THE CALENDAR. THE PERSISTENT
RIDGE OF HIGH PRESSURE OVER THE EASTERN PACIFIC OCEAN CONTINUED
THROUGH THE MONTH AND IN TURN ALLOWED THE JET STREAM TO DIVE SOUTH
OUT OF THE ARCTIC REGION AND INTO THE GREAT LAKES AS IT HAS DONE
MOST OF THE WINTER. SEVERAL COLD FRONTS WITH ARCTIC ORIGIN BROUGHT
VERY COLD AIR SOUTH WHICH KEPT TEMPERATURES WELL BELOW NORMAL FOR
THE MONTH.

THE AVERAGE MONTHLY TEMPERATURE AT SOUTH BEND WAS 30.0 DEGREES...7.5
DEGREES BELOW NORMAL. THIS RANKED AS THE 8TH COLDEST MARCH ON
RECORD. THE WARMEST TEMPERATURE OF THE MONTH OCCURRED ON THE LAST DAY
WITH A HIGH OF 68. THIS WAS THE WARMEST TEMPERATURE SINCE OCTOBER
2013. THE LOWEST TEMPERATURE OF THE MONTH WAS 4 BELOW ZERO ON THE
THIRD. THERE WERE 23 DAYS WITH AVERAGE TEMPERATURES BELOW NORMAL AND
14 OF THESE DAYS WERE MORE THAN 10 DEGREES BELOW NORMAL. MARCH THIRD
HAD THE GREATEST DEPARTURE OF 26 DEGREES BELOW NORMAL. THE HIGH ON
THAT DAY WAS JUST 18 AND THE LOW WAS 4 BELOW ZERO.

DESPITE IT BEING COLD IT WAS ACTUALLY A RELATIVELY DRY MONTH. THERE
WAS 1.69 INCHES OF PRECIPITATION...0.64 INCHES BELOW NORMAL. THIS
RANKED AS THE 24TH DRIEST MARCH ON RECORD.

...A RELATIVELY NORMAL APRIL...

DESPITE THE MONTH FEELING COOL...TEMPERATURES WERE ACTUALLY NEAR
NORMAL AND PRECIPITATION WAS BELOW NORMAL IN THE SOUTH BEND AREA.
THERE WERE NO PERIODS OF SUSTAINED WARMTH AND SEVERAL WINDY DAYS.
THIS LIKELY HELPED CREATE THE FEELING THAT IT WAS COLDER THAN
ACTUAL AIR TEMPERATURES INDICATED.

THE OVERALL WEATHER PATTERN BECAME MORE TYPICAL OF SPRING AS THE
DOMINANT WEST COAST RIDGE BROKE DOWN AND THE LARGE SCALE FLOW BECAME
MORE ZONAL ACROSS THE UNITED STATES. THIS ALLOWED FOR MORE
SEASONABLE TEMPERATURES BUT OCCASIONAL STORM SYSTEMS BROUGHT PERIODS
OF PRECIPITATION AND BELOW NORMAL TEMPERATURES. THERE WERE NO
SUSTAINED PERIODS OF WARMTH IN APRIL WITH THE LONGEST STRETCH OF
DAYS WITH ABOVE NORMAL TEMPERATURES BEING JUST FOUR FROM THE 10TH
THROUGH THE 13TH. THERE WERE 16 DAYS WITH BELOW NORMAL AVERAGE
TEMPERATURES. IT WAS ALSO A VERY WINDY MONTH WITH 18 DAYS HAVING A
PEAK WIND GUST OF 30 MPH OR GREATER AND 6 DAYS WITH A PEAK WIND OF
40 MPH OR HIGHER. THE FASTEST PEAK WIND GUST MEASURED WAS 49 MPH ON
THE 29TH.

THE AVERAGE MONTHLY TEMPERATURE WAS 49.2 WHICH WAS JUST 0.2 DEGREES
ABOVE NORMAL. THE WARMEST TEMPERATURE WAS 79 ON THE 21ST AND THE
COLDEST WAS 26 ON THE 6TH.

IT WAS ALSO A RELATIVELY DRY MONTH WITH JUST 2.35 INCHES OF
PRECIPITATION FALLING. THIS WAS 0.88 INCHES BELOW NORMAL AND RANKED
AS THE 34TH DRIEST APRIL ON RECORD. MARCH WAS ALSO A RELATIVELY DRY
MONTH WITH A DEFICIT OF NEARLY THREE QUARTERS OF AN INCH. APRIL
SNOWFALL WAS 1.1 INCHES...JUST THREE TENTHS OF AN INCH BELOW NORMAL.

...WET WITH SLIGHTLY ABOVE NORMAL TEMPERATURES FOR MAY...

MAY STARTED OUT RELATIVELY COOL AND DRY AT SOUTH BEND...WITH
TEMPERATURES NEAR OR BELOW NORMAL FOR THE FIRST 6 DAYS OF THE
MONTH...AND ONLY 0.19 INCHES OF PRECIPITATION OVER THE FIRST 8 DAYS.
WARMER AND WETTER WEATHER PATTERN WAS THE STORY FOR THE SECOND WEEK
OF THE MONTH...WITH MEASURABLE PRECIPITATION ON 7 OF THE 9 DAYS FROM
THE 9TH THROUGH THE 18TH AND 4 DAYS OF HIGH TEMPERATURES IN THE 80S
OR GREATER. THIS INCLUDED A HIGH TEMPERATURE OF 91 DEGREES ON THE
8TH. THIS IS THE 4TH EARLIEST FIRST 90 DEGREE DAY OF THE YEAR AT
SOUTH BEND ON RECORD...THE EARLIEST SINCE 1949...WHEN A HIGH
TEMPERATURE OF 90 WAS RECORDED ON MAY 5TH. ANOTHER COLD SPELL
IMPACTED THE REGION OVER THE THIRD WEEK OF THE MONTH...WITH A HIGH
OF 45 AND A LOW OF 32 ON THE 16TH. HOWEVER THE MONTH ENDED ON A WARM
SPELL...WITH AVERAGE TEMPERATURES ABOVE NORMAL ON 9 OUT OF THE LAST
12 DAYS OF THE MONTH...INCLUDING 7 CONSECUTIVE 80 DEGREE DAYS TO END
THE MONTH.

THE QUIET START TO THE SEVERE WEATHER SEASON CONTINUED INTO MAY
ACROSS THE SOUTH BEND AREA. ISOLATED STRONG TO SEVERE THUNDERSTORMS
IMPACTED PORTIONS OF THE REGION ON THE 9TH...11TH AND 13TH. MORE
WIDESPREAD STRONG TO LOW END SEVERE THUNDERSTORMS IMPACTED THE
REGION ON THE 20TH AND 21ST...AND SCATTERED STRONG THUNDERSTORMS
IMPACTED PORTIONS OF THE AREA ON THE 26TH THROUGH 28TH.

THE AVERAGE TEMPERATURE IN MAY AT FORT WAYNE WAS 60.7 DEGREES...WHICH
IS 1.4 DEGREES ABOVE NORMAL. THIS RANKS AS THE T-41ST WARMEST MAY ON
RECORD. THE WARMEST TEMPERATURE WAS 91 ON THE 8TH AND THE COLDEST
WAS 32 ON THE 16TH.

PRECIPITATION WAS ABOVE NORMAL WITH 5.10 INCHES FALLING DURING THE
MONTH. THIS IS 1.27 INCHES ABOVE NORMAL AND RANKS AS THE 29TH
WETTEST MAY ON RECORD. MEASURABLE RAINFALL FELL DURING 17 DAYS IN
MAY...WITH FIVE DAYS SEEING A HALF INCH OR MORE OF RAINFALL. THE
GREATEST 24 HOUR PRECIPITATION WAS 1.10 INCHES ON THE 26TH AND 27TH.

...OVERALL COOLER WITH NEAR NORMAL PRECIPITATION FOR SPRING 2014...

THE AVERAGE TEMPERATURE FOR THE SPRING SEASON AT SOUTH BEND WAS 46.7
DEGREES...WHICH IS 1.9 DEGREES BELOW NORMAL. SPRING 2014 WAS THE COLDEST
SPRING SEASON SINCE 2002...WHEN THE AVERAGE TEMPERATURE WAS 46.1 DEGREES.

THE PRECIPITATION TOTAL FOR THE SPRING SEASON WAS 9.14
INCHES...WHICH 0.34 INCHES BELOW THE SEASONAL NORMAL OF 9.48 INCHES.
THIS ONLY RANKS AS THE 52ND DRIEST SPRING SEASON ON RECORD. THIS
COMPARES VERY SIMILARILY TO THE PREVIOUS SPRING SEASON...WHEN 9.81
INCHES OF PRECIPITATION FELL IN SPRING 2013.

THE SPRING SEASON SNOWFALL AT SOUTH BEND WAS BASED ON VOLUNTEER
WEATHER OBSERVER REPORTS. A TOTAL OF 8.7 INCHES OF SNOW WAS
OBSERVED...0.2 INCHES ABOVE THE NORMAL OF 8.5 INCHES. DURING THE SPRING
OF 2013...12.2 INCHES OF SNOWFALL WAS RECORDED AT SOUTH BEND.
