Hydrologic Outlook issued April 16 at 2:19PM CDT by NWS Chicago IL
Issue date: 2026-04-16T19:19+00:00
ESFLOT Additional thunderstorms are expected Friday afternoon and Friday night across northern Illinois and northwest Indiana. Atmospheric conditions are favorable for some of these storms to produce locally heavy rainfall. Many rivers across northern Illinois and northwest Indiana remain elevated. Soil moisture also remains elevated in many areas, especially in northern Illinois along the Wisconsin border. Thus, any heavy rainfall that occurs could lead to flooding of rivers, creeks, urban and low-lying areas. Rivers such as the Rock, Fox and Des Plaines which are already in flood in some locations, may be especially prone to rainfall which could exacerbate ongoing flooding. 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. This outlook will be updated by Friday morning.
