...10TH WARMEST OCTOBER...
SOUTH BEND PICKED UP ABOUT TWO THIRDS OF THEIR NORMAL RAINFALL FOR
OCTOBER, WHILE LOCATIONS TO THE SOUTHWEST (INCLUDING FORT WAYNE)
WERE MUCH DRIER. IT IS NOT UNCOMMON TO HAVE LONG DRY STRETCHES
DURING THE FALL, HOWEVER, THERE WERE ONLY 6 DAYS OF MEASURABLE
RAINFALL THIS OCTOBER IN SOUTH BEND. MOST OF THE RAINFALL THIS MONTH
FELL ON OCTOBER 1ST WHEN 0.66" FELL. OCTOBER 2ND, 14TH, AND 16TH ALL
ALSO RECORDED OVER A QUARTER INCH. OVERALL, A TOTAL OF 2.05" OF RAIN
FELL DURING THE MONTH, WHICH IS 1.67" BELOW NORMAL AND RANKS AS THE
40TH DRIEST ON RECORD.
NO SNOW WAS RECORDED THIS MONTH. DESPITE THE AVERAGE FIRST SNOWFALL
OCCURING ON NOVEMBER 12TH, SOUTH BEND TYPICALLY AVERAGES 0.2" OF
SNOW IN OCTOBER. THE LAST TIME MEASURABLE SNOW FELL IN OCTOBER IN
SOUTH BEND WAS WHEN 1.4" FELL ON OCTOBER 31, 2023.
TEMPERATURES THROUGHOUT THE MAJORITY OF OCTOBER WERE MILD DUE TO A
PERSISTENT UPPER LEVEL RIDGE PATTERN ACROSS THE GREAT LAKES AND
MIDWEST REGIONS. 26 DAYS THIS MONTH HAD AN AVERAGE DAILY TEMPERATURE
ABOVE NORMAL, WITH 9 OF THOSE DAYS OVER 10 DEGREES ABOVE NORMAL.
OCTOBER IS PRONE TO LARGE TEMPERATURE SWINGS AS IT IS A TRANSITION
MONTH FROM SUMMER TO FALL, AND THIS MONTH WAS NO DIFFERENT. THE
WARMEST TEMPERATURE OCCURRED ON OCTOBER 12TH WITH A HIGH OF 86
DEGREES; A FEW DAYS LATER, THE COLDEST TEMPERATURE OF THE MONTH
OCCURRED ON OCTOBER 17TH WITH A LOW OF 32 DEGREES. THERE WERE SEVERAL
NIGHTS WITH LOWS IN THE MID 30S BUT THE GROWING SEASON LASTED
THROUGH THE MONTH AS THERE WAS NEVER A FREEZE IN SOUTH BEND
(TEMPERATURES ONLY REACHED FREEZING FOR AN HOUR ON THE MORNING OF
THE 17TH). OVERALL, OCTOBER HAD AN AVERAGE TEMPERATURE OF 58.0
DEGREES, WHICH IS 6.0 DEGREES ABOVE NORMAL AND RANKS AS THE 10TH
WARMEST ON RECORD.
TWO NEW TEMPERATURE RECORDS WERE SET THIS MONTH. THE AFOREMENTIONED
HIGH OF 86 DEGREES ON OCTOBER 12TH BROKE THE PREVIOUS DAILY RECORD
OF 84 DEGREES SET IN 2008. ADDITIONALLY, A RECORD WARM LOW WAS SET
ON OCTOBER 13TH OF 65 DEGREES; THIS BROKE THE OLD RECORD OF 62
DEGREES SET IN 1920.
