...LOCALLY HEAVY RAINFALL POSSIBLE TONIGHT INTO EARLY THURSDAY...

Thunderstorms are expected to develop across the area by this
evening, with the return of a very humid air mass which will
support the potential for heavy rainfall. While some uncertainty
still exists as to the exact location where the heaviest rains
will occur, areas south of a Dixon to Joliet to Rensselaer line
appear to have the greatest potential to see higher rainfall
amounts, potentially of 1 to 3 inches.

Given wet ground conditions from recent heavy rains, any
locations that receive additional heavy rainfall tonight into
early Thursday will likely be more susceptible to flooding than
normal. In addition, this would likely cause additional rises on
portions of the Illinois and Kankakee Rivers, where rises have
already occurred from recent rains.

Those with hydrologic concerns in these areas should maintain a
close watch on actual rainfall amounts and river stage forecasts.
Be sure to monitor later forecasts for updates on the heavy rain
and flooding potential tonight into early Thursday.
