From NWS IWX social media:
Yes, you are reading this correctly, South Bend, IN had 10.06" of rain in June! This is incredibly rare to have over 10" of rainfall in just one month (especially taking into consideration that rainfall this June came from efficient heavy rainfall producing thunderstorms rather than from tropical remnants). There has only been one other time 10"+ of rainfall has occurred in June (1993 with 10.86", which is the monthly record rainfall). June 2026 was the 2nd wettest June on record in South Bend. Since records began in 1893, 10"+ of rainfall has only happened 3 other times. 10.06" in June 2026 ranks as the 4th wettest month ever in South Bend's history, behind 13.92" (Sept 2008), 12.81" (August 2016), and 10.86" (June 1993).
