Hydrologic Outlook

National Weather Service Chicago IL

326 PM CDT Wed Mar 13 2024



...Localized heavy rainfall possible tonight...

        

Showers and thunderstorms are expected to develop later tonight and 

continue at least into Thursday morning. Widespread rainfall amounts 

up to one inch are possible, especially near and south of I-80. A 

narrow corridor of heavier rainfall is possible, generally between 

I-80 and portions of central Illinois. Within this corridor, local 

areas may see rainfall of 2-4 inches.



Vegetation remains somewhat dormant and soil moisture is above 

average in northeast and east central Illinois, which will reduce 

infiltration and allow for a larger portion of rainfall to runoff 

into streams and rivers. Ensemble river forecast guidance suggests 

that river rises are possible in the Kankakee, Vermilion, and 

Illinois river basins, with only low probabilities for bankfull or 

minor flood conditions. While widespread flooding is not likely, a 

few streams and rivers may near bankfull on Thursday, and localized 

flooding of creeks, ditches, and poor drainage areas would result if 

a corridor of heavy rainfall occurs.

         

This outlook means that elevated water levels and potential impacts 

are possible, but not yet certain. Persons should closely monitor 

forecasts including the possibility of flood watches, warnings, and 

advisories.

 

No additional outlooks are expected for this event.
