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.
