September 2022 Summary

The first week of the month saw the most active weather, especially on the 3rd-4th when a very slow-moving area of low pressure pushed through. A nearly stationary thunderstorm over Switzerland County, Indiana produced over nine inches of rain, as measured by a CoCoRaHS observer. While the heaviest rain was in northwestern Switzerland County, groundwater flowed rapidly into Brushy Creek in Jefferson County, Indiana, causing the stream to rage out of its banks. Several homes were washed away and the body of an elderly woman was found five miles downstream. Elsewhere, torrential downpours stripped the blacktop from a road in Franklin County. Several homes were damaged, with one swept of its foundation, in Shelby County. While flash flooding was the main impact from the storms on the 3rd, a few trees were blown down by severe storms moving through Simpson and Warren Counties.

The weather dried out mid-month, which set the stage for heat to set in from the 19th to the 21st. The hot weather peaked on the 21st ahead of an incoming cold front, with temperatures reaching the lower and middle 90s. Then the following day, behind the front, afternoon readings were in the 70s!

The cool weather persisted for the remainder of the month, and there was even a bit of widely scattered light frost on the morning of the 28th.
