September was typically quiet in 2021, with no severe weather in southern Indiana or central Kentucky. The most significant weather-maker of the month took place on the 15th when a cold front coming in from the northwest interacted with moisture streaming north from tropical cyclone Nicholas to produce widespread rain and scattered flooding. Bardstown was by far the hardest hit, with a local CoCoRaHS volunteer reporting about half a foot of rain.
