Hydrologic Outlook issued April 3 at 4:21AM CDT by NWS Chicago IL

ESFLOT

Flooding of rivers, creeks, ditches, and poor drainage areas is
possible across portions of northeast Illinois and northwest Indiana
late Friday into Saturday. River rises and flooding will be possible
along the Iroquois, Kankakee, and Illinois rivers.

Periods of showers with possible embedded thunderstorms will move
through the region late Friday into Saturday. Widespread rainfall
amounts of 1 to 2 inches may occur near and south of Interstate 80,
with localized amounts in excess of 2 inches possible.

Runoff from any rainfall will be increased due to high soil moisture
from recent rains and may lead to rises on area streams and rivers
in addition to localized flooding of poor drainage areas. While
confidence in where the highest rainfall totals occur remains low at
this time, there is a higher potential for areas near and south of
Interstate 80.

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.

The next scheduled update to this outlook is expected this afternoon.
