...A WARM SPRING AND THE LEAST SNOWIEST SPRING ON RECORD...

THE METEOROLOGICAL SPRING SEASON...MARCH THROUGH MAY...WAS VERY WARM
WITH NO MEASURABLE SNOWFALL AND ABOVE NORMAL PRECIPITATION. THIS
TIES AS THE LEAST SNOWIEST SPRING ON RECORD SINCE RECORDS BEGAN IN
1897 AT FORT WAYNE.

AFTER A RATHER COLD AND DREARY WINTER...MARCH BEGAN METEOROLOGICAL
SPRING WITH SEVERAL SUNNY DAYS AND CLEAR NIGHTS. THE SECOND WEEK OF
THE MONTH WAS EVEN WARMER WITH TEMPERATURES CLIMBING INTO THE 50S
AND 60S AND AVERAGE DAILY TEMPERATURES RANGING FROM 10 TO 20 DEGREES
ABOVE NORMAL. THE THIRD AND FOURTH WEEKS OF THE MONTH WERE NOT NEAR
AS WARM AS THE MIDDLE PORTION...BUT AVERAGE TEMPERATURES WERE
GENERALLY ABOVE NORMAL WITH ONLY A FEW DAYS BELOW NORMAL. THE FINAL
DAY OF MARCH ENDED ON A WARM NOTE WITH HIGH TEMPERATURES FINALLY
HITTING THE MAGICAL 70 DEGREE MARK FOR THE FIRST TIME THIS
YEAR...REACHING 75 DEGREES. THERE WERE ONLY 4 DAYS DURING THE MONTH
WITH AN AVERAGE TEMPERATURE BELOW NORMAL.

PRECIPITATION DURING MARCH WAS BELOW NORMAL AND MEASURABLE
PRECIPITATION WAS CONFINED TO JUST 10 DAYS. THERE WAS ALSO NO
SNOWFALL FOR THE ENTIRE MONTH...NOT EVEN A TRACE. THERE HAVE ONLY
BEEN FIVE OTHER YEARS IN WHICH NO MEASURABLE SNOWFALL WAS RECORDED
AT FORT WAYNE IN THE MONTH OF MARCH...2009...1990...1946...1927 AND
1921.

APRIL CONTINUED THE WARM SPRING PATTERN BUT MONTHLY PRECIPITATION
ENDED UP BEING ABOVE NORMAL FOR THE FIRST TIME THIS YEAR. THERE WAS
ONLY A TRACE OF SNOWFALL FOR THE MONTH WITH A FEW FLURRIES IN THE
AIR ON THE 9TH.

THE MONTH BEGAN ON A VERY WARM NOTE WITH HIGHS IN THE LOWER 80S ON
THE FIRST AND SECOND. AVERAGE DAILY TEMPERATURES FOR THESE TWO DAYS
WERE 22 AND 23 DEGREES ABOVE NORMAL RESPECTIVELY. THE COOLEST HIGH
TEMPERATURE DURING THE FIRST 7 DAYS OF THE MONTH WAS 70 DEGREES ON
THE 3RD. THE REMAINDER OF THE MONTH WOULD SEE A REPEATING PATTERN
WHICH WOULD BRING WARMER TEMPERATURES FOR SEVERAL DAYS FOLLOWED BY A
COLD FRONT AND COOLER TEMPERATURES FOR A FEW DAYS. THERE WERE ONLY 6
DAYS DURING THE MONTH WITH AN AVERAGE DAILY TEMPERATURE BELOW
NORMAL.

PRECIPITATION AT FORT WAYNE WAS ABOVE NORMAL FOR APRIL...BUT JUST
BARELY. OVER AN INCH AND A QUARTER OF RAINFALL OCCURRED BETWEEN THE
3RD AND 8TH OF APRIL. THE MIDDLE PORTION OF THE MONTH WAS GENERALLY
DRY. DEEPER MOISTURE FROM THE GULF OF MEXICO FINALLY MADE IT BACK TO
THE AREA DURING THE PERIOD OF THE 23RD THROUGH THE 26TH. OVER TWO
INCHES OF MUCH NEEDED RAIN FELL DURING THIS PERIOD. ESSENTIALLY
THESE TWO PERIODS ACCOUNTED FOR NEARLY ALL THE MONTHLY RAINFALL.

MAY WAS A WARM AND WET MONTH AS MUCH NEEDED RAINFALL BROUGHT THE
MONTHLY TOTAL ABOVE NORMAL FOR JUST THE SECOND TIME THIS YEAR. IT
WAS ALSO A RELATIVELY WARM MONTH WITH AVERAGE TEMPERATURES ENDING
ABOVE NORMAL.

THE MONTH BEGAN ON A WARM AND WET NOTE AND THIS WAS BASICALLY THE
TREND FOR NEARLY THE ENTIRE MONTH. ALMOST HALF AN INCH OF RAINFALL
OCCURRED ON THE FIRST AND SECOND AND MEASURABLE RAINFALL OCCURRED ON
15 OF THE FIRST 21 DAYS. THERE WERE FOUR SEPARATE RAIN EVENTS IN
WHICH EACH PRODUCED OVER AN INCH OF RAINFALL. CONDITIONS DID BRIEFLY
DRY OUT LATE IN THE MONTH WITH A STRETCH OF NO MEASURABLE
PRECIPITATION FROM MAY 22ND THROUGH THE 29TH. THUNDERSTORMS BROUGHT
ADDITIONAL RAINFALL DURING THE LATTER HALF OF THE MEMORIAL DAY
WEEKEND WITH OVER AN INCH OF RAIN ON MEMORIAL DAY.

HIGH TEMPERATURES EQUALLED OR EXCEEDED 90 DEGREES ON 2 DAYS...80
DEGREES ON 12 DAYS...AND 70 DEGREES ON 21 DAYS. HIGH TEMPERATURES
WERE ABOVE 80 DEGREES ON THE LAST 9 DAYS OF THE MONTH. THERE WAS A
BRIEF COOL STRETCH FROM MAY 8TH TO THE 10TH WHERE HIGH TEMPERATURES
REMAINED AT 60 DEGREES OR LESS. THIS COOL STRETCH WAS SHORT LIVED AS
THE HIGH TEMPERATURE ON THE 13TH JUMPED TO 83 DEGREES. THERE WAS A
DIFFERENCE OF 29 DEGREES BETWEEN THE HIGH TEMPERATURES ON THE
12TH...54 DEGREES...AND THE 13TH...83 DEGREES. THE HIGH TEMPERATURE
FROM MAY 23RD THROUGH MAY 31ST WAS AT LEAST 85 DEGREES EACH DAY AND
91 DEGREES ON THE 26TH AND 30TH. DESPITE THE VERY WARM HIGH
TEMPERATURES...MANY NIGHTS WERE COOL WITH LOW TEMPERATURES BELOW
NORMAL. IRONICALLY...10 DAYS IN MAY EXPERIENCED DAILY AVERAGE
TEMPERATURES BELOW NORMAL.

THE AVERAGE TEMPERATURE FOR THE SPRING SEASON WAS 54.6 DEGREES...5.4
DEGREES ABOVE NORMAL. THIS RANKS AS THE 3RD WARMEST SPRING ON RECORD
AT FORT WAYNE. PRECIPITATION DURING THIS SEASON WAS 13.22
INCHES...3.07 INCHES ABOVE NORMAL.

SNOWFALL FOR THE ENTIRE SPRING SEASON OF MARCH THROUGH MAY WAS JUST
A TRACE...WHICH IS 5.8 INCHES BELOW NORMAL. THIS TIES AS THE LEAST
SNOWIEST SPRING ON RECORD AT FORT WAYNE SINCE RECORDS BEGAN IN 1897.
OTHER SPRING SEASONS WITH NO MEASURABLE SNOWFALL INCLUDE 1927...1946
AND 1990.

SNOWFALL FOR THE ENTIRE WINTER PERIOD...INCLUDING THE FALL...WINTER
AND SPRING SEASONS WAS 29.3 INCHES...5.8 INCHES BELOW THE NORMAL OF
35.1 INCHES. ALL OF THIS SNOWFALL FELL IN THE THREE WINTER MONTHS OF
DECEMBER...JANUARY AND FEBRUARY.
