..FIRST SUMMER HEAT WAVE
WHILE JUNE 1 WAS NOTABLY COOL (DAILY AVERAGE TEMPERATURE WAS 11
DEGREES BELOW NORMAL), THE REMINDER OF THE MONTH WAS WARMER THAN
NORMAL. ONLY SIX DAYS THIS MONTH SAW AN AVERAGE DAILY TEMPERATURE
BELOW NORMAL. DURING A LATE-MONTH HEAT WAVE, SOUTH BEND SET THREE
RECORD WARM MINIMUM TEMPERATURES (JUNE 22, 23, 24) AND RECORDED A
HIGH TEMPERATURE OF 90 OR GREATER FOR SEVEN STRAIGHT DAYS.
THE LONGEST STRETCH OF 90S ON RECORD IS 15 DAYS BACK IN 1901. JUNE
OF LAST YEAR SAW AN SEVEN-DAY STRETCH END ON JUNE 22ND. EARLY JULY
2020 RECORDED EIGHT STRAIGHT 90-DEGREE DAYS. THE TOTAL NUMBER OF 90
DEGREE DAYS THIS MONTH IS NINE, MATCHING THAT OF JUNE 2024 AND IS
ABOVE THE AVERAGE OF FOUR.
THE AVERAGE TEMPERATURE FOR THE MONTH WAS 72.7 DEGREES WHICH IS 3.9
DEGREES ABOVE NORMAL. THIS RANKS AS THE 10TH WARMEST JUNE OF RECORD.
THIS WAS THE WARMEST JUNE SINCE 2021 (73.0 DEGREE AVERAGE) AND WAS
ONLY SLIGHTLY WARMER THAN JUNE 2024 (72.4 DEGREE AVERAGE).
WHILE 90-DEGREE DAYS CERTAINLY NUDGED THE MONTH'S AVERAGE
TEMPERATURE ABOVE NORMAL, OVERNIGHT LOWS CARRIED NOTABLE WEIGHT. THE
MONTH'S AVERAGE LOW TEMPERATURE OF 62.3 DEGREES TIES AS THE 8TH
WARMEST ON RECORD.
AMID THE HOT AND STEAMY CONDITIONS, PASSING THUNDERSTORMS BUBBLED UP
AT TIMES AND RAINFALL RATES WERE VERY EFFICIENT. FOR EXAMPLE, 1.01"
OF RAIN WAS RECORDED ON THE 27TH BUT 0.98" OF THIS TOTAL WAS
RECORDED IN ONE HOUR DURING THE EARLY MORNING HOURS. ON THE EVENING
ON JUNE 17, SLOW-MOVING THUNDERSTORMS BECAME ANCHORED OVER NEARBY
GRANGER, IN, RESULTING IN A COCORAHS REPORT OF 4.92 INCHES IN A
MANNER OF ABOUT 3 TO 4 HOURS. THE SOUTH BEND AIRPORT RECORDED 0.00"
THIS DAY.
ALL TOLD, THE MONTH'S PRECIPITATION TOTALED 5.01 INCHES WHICH IS
0.97 INCHES ABOVE NORMAL. THIS RANKS AS THE 30TH WETTEST JUNE ON
RECORD. THIS IS THE MOST JUNE RAINFALL SINCE 9.67 INCHES IN 2021.
