...SPRING 2025: WARM WITH NEAR NORMAL PRECIPITATION AND A LACK OF
SNOWFALL...
DESPITE A COOLER THAN NORMAL MAY, SPRING OVERALL WAS MUCH WARMER
THAN NORMAL. THERE WERE SEVERAL STRETCHES OF WARMER THAN NORMAL
TEMPERATURES (INCLUDING OVERNIGHT LOWS) IN MARCH AND APRIL THAT
HELPED BOOST THE OVERALL SPRING AVERAGE TEMPERATURE. THE AVERAGE
TEMPERATURE FROM MARCH TO MAY WAS 51.7 DEGREES, WHICH IS 1.7 DEGREES
ABOVE NORMAL. THIS RANKS AS THE 17TH WARMEST SPRING ON RECORD.
RECORDS BEGAN IN 1897.
THIS SPRING WAS NOTABLY DRIER THAN LAST YEAR, WHICH WAS A TOP 5
WETTEST SPRING ON RECORD AND HAD AN ABUNDANCE OF PRECIPITATION. AT
THE START OF MARCH, MUCH OF THE AREA WAS EXPERIENCING D1 DROUGHT
CONDITIONS (MODERATE DROUGHT). DROUGHT GRADUALLY IMPROVED THROUGHOUT
MARCH AS A SERIES OF LOW PRESSURE SYSTEMS TRACKED THROUGH THE GREAT
LAKES REGION. PERIODS OF DRY CONDITIONS IN APRIL AND MAY LED TO D1
CONDITIONS BEING REINTRODUCED ACROSS PARTS OF NORTHWEST AND NORTH-
CENTRAL INDIANA. BY THE END OF MAY, ABOUT 21% OF INDIANA WAS
EXPERIENCING D1 DROUGHT CONDITIONS. 1.51" OF RAIN FELL ON APRIL 2ND,
WHICH IS THE FIRST AND ONLY DAY THIS SPRING TO HAVE HAD A DAILY RAIN
TOTAL OVER 1". IN TOTAL, 9.21" OF PRECIPITATION FELL FROM MARCH TO
MAY, WHICH IS 1.92" BELOW NORMAL. THIS RANKS AS THE DRIEST SPRING
SINCE 2022 AND THE 49TH DRIEST SPRING SINCE RECORDS BEGAN.
WITH A WARMER THAN NORMAL SPRING, IT SHOULD COME AS NO SURPRISE THAT
SNOWFALL WAS NOTABLY LACKING. ONLY 0.3" OF SNOW FELL THIS SPRING,
WHICH IS 5.1" BELOW NORMAL. THIS TIES AS THE 7TH LEAST SNOWY
SPRING ON RECORD.
A MONTH BY MONTH SUMMARY IS BELOW.
MARCH
...TOP 15 WARMEST MARCH ON RECORD...
MARCH 2025 WAS VERY MILD WITH A NOTABLE LACK OF PRECIPITATION,
ESPECIALLY SNOWFALL. THE MONTH WAS NOTICEABLY WARMER THAN NORMAL,
WITH SEVERAL DAYS WITH HIGHS IN THE UPPER 60S TO MID 70S DURING THE
MIDDLE AND END OF THE MONTH. MANY THESE WARMER DAYS ALSO BROUGHT
ABOUT PERIODS OF ACTIVE WEATHER. THE MIDDLE TO END OF THE MONTH WAS
ESPECIALLY ACTIVE, WITH SEVERAL AREAS OF LOW PRESSURE MOVING THROUGH
THE MIDWEST AND GREAT LAKES REGIONS. THESE AREAS OF LOW PRESSURE
BROUGHT PERIODS OF STORMS TO THE AREA, WITH SEVERE WEATHER OCCURRING
ON MARCH 19TH AND MARCH 30TH. STRAIGHTLINE WIND DAMAGE WAS OBSERVED
WITH BOTH SEVERE WEATHER EVENT AND A FEW ISOLATED TORNADOES OCCURRED
TOO.
MILD TEMPERATURES LED TO MARCH 2025 RANKING AS THE 11TH WARMEST ON
RECORD (RECORDS BEGAN IN 1897). THE AVERAGE TEMPERATURE WAS 44.3
DEGREES, WHICH IS 5.7 DEGREES ABOVE THE NORMAL AVERAGE TEMPERATURES
OF 38.6 DEGREES. THE WARMEST DAY OF THE MONTH WAS MARCH 14TH, WHEN
THE HIGH TEMPERATURE REACHED 78 DEGREES.
DESPITE THE ACTIVE WEATHER TOWARDS THE LATTER HALF OF THE MONTH,
PRECIPITATION WAS HARD TO COME BY IN FORT WAYNE. WHILE THERE WERE A
FEW DAYS THIS MONTH OF PRECIP TOTALS BETWEEN 0.25-0.50", THE HIGHEST
DAILY TOTAL THIS MONTH WAS 0.86" ON MARCH 4TH. THIS IS THE 10TH
MONTH IN A ROW WITHOUT A DAILY TOTAL GREATER THAN 1"; THE LAST TIME
1" OR MORE OF PRECIPITATION FELL IN ONE DAY IN FORT WAYNE WAS ON MAY
7TH, 2024. OVERALL, MARCH 2025 HAD 2.30" OF PRECIPITATION, WHICH IS
0.51" BELOW NORMAL. THIS RANKS AS THE 42ND DRIEST MARCH ON RECORD.
WITH SUCH MILD TEMPERATURES THIS MONTH, IT IS NO SURPRISE THAT
SNOWFALL WAS SIGNIFICANTLY LACKING. ONLY 0.3" FELL THE ENTIRE MONTH,
WHICH WAS 4.3" BELOW NORMAL. MARCH 2025 TIES FOR THE 14TH LEAST
SNOWY MARCH ON RECORD. WHILE THERE CAN BE SNOWSTORMS IN MARCH, THEY
HAVE BEEN HARD TO COME BY IN THE PAST DECADE. WITH THE LARGE
TEMPERATURE SWINGS THAT TYPICALLY OCCUR IN THE TRANSITION FROM
WINTER TO SPRING, IT IS ALSO NOT UNUSUAL TO HAVE A LACK OF SNOW IN
MARCH. THE LAST TIME MARCH SNOWFALL WAS ABOVE NORMAL IN FORT WAYNE
WAS IN 2015; IN THE PAST 25 YEARS, ONLY 7 YEARS HAVE HAS MARCH
SNOWFALL ABOVE AVERAGE.
APRIL
...SLIGHTLY ABOVE NORMAL TEMPERATURES; NEAR NORMAL PRECIPITATION...
SEVERE THUNDERSTORMS ON THE SECOND SPAWNED EIGHT TORNADOES ACROSS
INDIANA, SOUTHERN MICHIGAN AND NORTHWEST OHIO. THUNDERSTORM WIND
GUSTS IN EXCESS OF 60 MPH WERE COMMON, DOWNING TREES AND POWERLINES
AS WELL. THIS WAS ALSO WHEN 1.51 INCHES OF RAIN WAS RECORDED AT FORT
WAYNE ; A NEW RECORD SURPASSING THE PREVIOUS TOTAL OF 0.83 INCHES IN
1983. A PROGRESSIVE WEATHER PATTERN BROUGHT FREQUENT RAIN (AND EVEN
SNOW) CHANCES EARLY ON IN APRIL ALONG WITH LARGE TEMPERATURE SWINGS
AS IS TYPICAL FOR SPRING IN THE MIDWEST. TEMPERATURES TENDED TO BE
BELOW NORMAL IN THE FIRST HALF OF THE MONTH FOLLOWED BY A NOTABLE
WARM UP IN THE FINAL TEN DAYS. THREE DAYS THIS MONTH RECORDED A
TEMPERATURE OF 80 OR WARMER; A COMMON OCCURRENCE OVER THE PAST
SEVERAL YEARS.
THE AVERAGE TEMPERATURE FOR THE MONTH WAS 51.4 DEGREES WHICH IS 1.2
DEGREES ABOVE NORMAL. THIS RANKS AS THE 28TH WARMEST ON RECORD (TIED
WITH 1987, 1981, 1900). PRECIPITATION TOTALED 3.90 INCHES WHICH IS
ONLY SLIGHTLY ABOVE NORMAL BY 0.16 INCHES AND RANKS AS THE 41ST
WETTEST ON RECORD. THIS IS NOTABLY LESS THAN APRIL 2024 WHEN 7.39
INCHES WAS RECORDED. A TRACE OF SNOW WAS RECORDED WHICH IS 0.8
INCHES BELOW NORMAL.
MAY
...SLIGHTLY COOLER THAN NORMAL AND DRIER THAN USUAL...
THE MOST NOTABLE FEATURE THIS MONTH WAS THE WIDESPREAD STRONG 40 TO
70 MPH WINDS THAT MOVED THROUGH ON THE 16TH. A 71 MPH WIND GUST
REPORT WAS RECORDED NORTH OF NEW HAVEN AND A 66 MPH GUST WAS
RECORDED AT THE FORT WAYNE INTERNATIONAL AIRPORT. ADDITIONALLY, A
PLUME OF DUST FROM CROP FIELDS WAS KICKED UP AND IT REDUCED
VISIBILITY IN AREAS AS IT WENT NORTHWARD. THIS WAS MOST NOTABLE IN
AREAS WEST OF US-31. 70 DEGREE DEW POINTS ON THE 15TH WERE REPLACED
BY A DRIER AREA OF 40 AND 50 DEGREE DEW POINTS ON THE 16TH AND THIS
DRIER AIRMASS HELPED FACTOR INTO THE STRONG WIND GUSTS OBSERVED AS A
PLAINS-LIKE INVERTED-V PROFILE SETUP OCCURRED. ONLY A TRACE AND A
TENTH OF RAINFALL WAS OBSERVED ON THE 15TH AND 16TH RESPECTIVELY.
AS FOR TEMPERATURE, THIS MONTH FINISHED COOLER THAN NORMAL.
TEMPERATURES THROUGHOUT THE FIRST HALF OF THE MONTH AVERAGED NORMAL
TO ABOVE NORMAL, WHEREAS THE LATTER HALF OF THE MONTH (THE 18TH
THROUGH 31ST) WAS MUCH COOLER AND THIS REALLY HELPED TO AVERAGE
THINGS OUT. OVERALL, THE AVERAGE TEMPERATURE WAS 59.3 DEGREES, WHICH
IS 2.0 DEGREES BELOW NORMAL. THIS RANKS AS THE 52ND COOLEST MAY ON
RECORD. RECORDS BEGAN IN 1897.
PRECIPITATION-WISE, THIS MONTH FINISHED BELOW NORMAL. THREE DAYS
THIS MONTH HAD OVER A HALF INCH OF RAIN: MAY 4TH, MAY 5TH, AND MAY
20TH. MAY 4TH WAS THE WETTEST DAY THIS MONTH WITH 0.99" OF RAIN. IN
TOTAL, 3.01" OF PRECIPITATION FELL THIS MONTH, WHICH IS 1.57" BELOW
NORMAL. THIS TIES FOR THE 45TH DRIEST MAY ON RECORD.
