..7TH WARMEST AND 5TH WETTEST APRIL ON RECORD
A PROGRESSIVE UPPER-AIR PATTERN RESULTED IN A NUMBER OF STORMS AND
HEAVY RAIN THIS MONTH. RIGHT AWAY, THE FIRST FOUR DAYS OF APRIL
BROUGHT SEVERE THUNDERSTORMS AND 1.97 INCHES OF RAIN. THIS RESULTED
IN IMMEDIATE RISES ON AREA CREEKS AND STREAMS SENDING THEM INTO
MINOR OR EVEN MODERATE FLOOD STAGE. AS WATER LEVELS RECEDED, AN
ADDITIONAL 1.70 INCHES OF RAIN FELL FROM THE 13TH THROUGH 16TH,
RESULTING IN RENEWED RISES ON AREA WATER WAYS. ONE MORE WALLOP OF
HEAVY RAIN OCCURRED ON THE 27TH (1.13). WHAT WAS MORE IMPRESSIVE
THAT DAY WAS THE WAKE LOW THAT MOVED THROUGH, PRODUCING A 70MPH WIND
GUST AT SOUTH BEND! A 6 MB PRESSURE DROP WAS RECORDED IN ONE HOUR
AND A NUMBER OF TREES WERE DOWNED IN THE GREATER SOUTH BEND AREA,
WITH DAMAGE NOTED AS FAR EAST AS CENTREVILLE, MI. ONE TORNADO WAS
CONFIRMED ON THE NORTHWEST SIDE OF SOUTH BEND (GERMAN TOWNSHIP) ON
APRIL 18TH. WITH SUCH AN ACTIVE APRIL FOR SEVERE WEATHER, NWS
NORTHERN INDIANA ISSUED 58 SEVERE THUNDERSTORM WARNINGS AND 6
TORNADO WARNINGS ACROSS NORTHERN INDIANA, FAR SOUTHERN MICHIGAN, AND
NORTHWEST OHIO. THIS IS MORE THAN DOUBLE THE PREVIOUS RECORD FOR
SEVERE THUNDERSTORM WARNINGS FOR OUR FORECAST AREA, WHICH WAS 28 IN
2001.
TOTAL RAINFALL THIS MONTH WAS 6.22 INCHES. THIS RANKS AS THE 5TH
WETTEST APRIL ON RECORD AND IS THE WETTEST SINCE 7.24 INCHES IN
2011. THE WETTEST DAY THIS MONTH WAS APRIL 27TH WITH 1.13".
WHILE THERE WERE EPISODES OF BELOW NORMAL TEMPERATURES, INCLUDING AT
LEAST ONE FROSTY MORNING (23 DEGREES ON APRIL 7TH), TEMPERATURES
WERE UNSEASONABLY WARM FOR THE MONTH. THE AVERAGE TEMPERATURE OF
53.8 DEGREES RANKS AS THE 7TH WARMEST ON RECORD AND IS THE WARMEST
APRIL SINCE 2010. ONE TEMPERATURE RECORD WAS TIED THIS MONTH: WARM
LOW TEMPERATURE OF 59 ON THE 14TH TIED THE RECORD SET IN 1959.
LASTLY, THERE WERE 5 DAYS THIS MONTH WITH A HIGH OF AT LEAST 80
DEGREES. THIS TIES AS THE 3RD MOST ON RECORD, MATCHING 2023 FOR
NUMBER OF 80-DEGREE DAYS. THE WARMEST DAY THIS MONTH WAS APRIL 14TH
WITH A HIGH TEMPERATURE OF 82 DEGREES.
NO SNOW WAS RECORDED THIS MONTH, WHICH IS 1 INCH BELOW NORMAL. THIS
WAS THE 4TH CONSECUTIVE APRIL WITHOUT MEASURABLE SNOW. THIS WAS THE
6TH TIME ON RECORD THAT NO SNOW (NOT EVEN A TRACE) WAS RECORDED IN
SOUTH BEND IN APRIL.
