Wider weather episode

The remnants of Tropical Storm Gordon interacted with a surface front to produce widespread heavy rain across much of central Indiana. The moisture content of the atmosphere was very high. Precipitable water, a measure of moisture content in the atmosphere, is normally around 1 inch for early September in Indiana. Precipitable water amounts approached 2 inches for parts of the area on September 8th. Heavy rainfall of 1 to 4 inches fell on the 7th of September, while the 72-hour total rainfall amounts ending the morning of September 9th came in between 4 and 6 inches were common with some locally higher amounts. This caused some Flash Flooding in the southern half of the area, and more general flooding at other locations.
