Just saw this on another message board I belong to. I’ve personally seen just over 8” of rain in one day when I was stationed in Korea, I could not imagine getting as much as Madison. Surprisingly, we are not hearing about it here on the news that is on the radio (don’t have TV to know what is being broadcast there).
Sorry, but I don't have an answer for you. I haven't been up in that area since this spring but it was fairly wet then. I think they have gotten above average rainfall this summer so I would have to think it's pretty wet. Not much of the state has escaped all the rain.
