Hydrologic Outlook
National Weather Service Chicago IL
218 PM CDT Sun Mar 24 2024

...Rises in river levels to bankfull and ponding in low-lying spots
possible Monday night and Tuesday...

A strong storm system will deliver waves of showers and a few
thunderstorms Monday afternoon through Tuesday. Widespread rainfall
amounts over 1 inch are possible with embedded streaks as high as 3
to 4 inches. The exact placement of the heaviest rainfall will
depend on the ultimate movement of the most persistent showers and
thunderstorms, with our forecast currently favoring areas west of
Interstate 55 as having the highest threat for more than 1 inch of
rain.

With vegetation remaining dormant and soil moisture remaining above
average, soil infiltration of rainfall will be limited and cause
increased runoff into low lying spots and rivers. As a result,
rivers may rise to or above bankfull, and low-lying locations with
poor drainage such as farm fields and ditches may flood where the
rain is heaviest.

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.

Additional hydrologic outlooks may be issued over the next 24 hours
as the rainfall event nears.
