Driving home major roads leading into Mascoutah were flooded and closed. This was due to a localized bullseye of historical rain falling just a few miles away. Scott Air Force base recorded almost 6" of rain. 3" fell in one hour causing major creeks and farmland to flood.

1/11/2020 1/12/2020 6:00 AM 2 3.59 T M Was out of town during the past 24 hours. I arrived back yesterday around 4pm and emptied 3.40" of rain from gauge. Around 5:30pm, rain started to mix with sleet, and snow. I had to leave my house for a few hours. When I got back around 11pm, there was about .1" of ice and snow observed on the snowboard. However, the rest of the yard there was spotty, small amounts of snow in grassy areas. It's possible there was more snow, that possibly melted as temperatures hovered around freezing. So this was my best snow estimate. This morning I melted .19" of rain and melted snow from gauge that fell after 4pm yesterday till early evening, therefore, making the multi-day precipitation total of 3.59". Just trace amounts of snow.
