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.
