Hydrologic Outlook
National Weather Service Chicago IL
348 PM CDT Fri Mar 29 2024

...Isolated heavy rainfall possible overnight into tomorrow
morning...

Showers and thunderstorms are expected to develop late tonight in
eastern Iowa and northwestern Illinois. These showers and
thunderstorms may produce heavy rainfall rates up to one inch per
hour as they move east across northern Illinois and northwestern
Indiana. Soil moisture across most of the area ranges from near
average to slightly above average across the area, which will have
only a limited impact on runoff rates. Although most areas will
receive only 0.5 inches of rainfall or less, a narrow corridor may
receive localized rainfall up to 1.5 to 2.0 inches from multiple
rounds of showers and thunderstorms. If rainfall of this magnitude
occurs, minor flooding of ditches, small streams, and poor drainage
areas would be expected. Widespread flooding is unlikely.

This outlook means that elevated water levels and potential impacts
are possible, but not yet certain.

No additional outlooks are expected for this event unless the threat
for heavy rainfall becomes more certain.
