Period of showers and thunderstorms are expected Wednesday.
Thunderstorms will be very efficient at producing torrential
rainfall, with some areas likely receiving up 2 inches of rain in
just an hour. Rainfall that intense would likely result in flash
flooding.

In addition, localized rainfall totals in excess of 3 inches are
possible across northern and central Illinois and northwest
Indiana through the day Wednesday, which could result in
significant rises and possible flooding on area streams and
rivers.

Recent heavy rainfall has left streamflow above average in many
areas and grounds still saturated. This will further increase the
threat of flooding.

Anyone in or near flood prone areas should closely monitor later
forecasts.
