Hydrologic Outlook issued June 8 at 12:44PM CDT by NWS Chicago IL

Effective: Mon June 8, 2026, 12:44 PM
Expires: Tue June 9, 2026, 12:00 AM

ESFLOT Periods of showers and thunderstorms are expected to move back into northern Illinois this afternoon and evening. Some showers and thunderstorms will be capable of rain rates of 2-3 inches per hour, which could cause isolated flooding, especially in urban areas or areas that recently received heavy rainfall. Atmospheric conditions are very favorable for high rainfall rates as precipitable water values have been observed just under 2 inches with forecasted values near or exceeding 2 inches by later today. Despite the favorability for heavy rainfall, most of northern Illinois is experiencing drought conditions with low rivers and low soil moisture. Due to dry conditions, higher rainfall rates will be required for flooding, making the scope of possible flooding more isolated. Locations with the highest chance of ponding and localized flooding due to heavy rainfall are urban areas or areas that received heavy rainfall over the last few days, including isolated portions of La Salle, Livingston, Ford, Iroquois, Kankakee, and Will counties. This outlook means that elevated water levels and potential impacts are possible, but not yet certain. Persons should closely monitor the latest forecasts. No updates to this outlook product are currently scheduled.

The times presented here are based upon the solunar theory, which is the idea that the movements of fish and other animals are affected by the location of the sun and moon. The major periods are believed to be the times of the greatest animal activity and occur when the moon is directly overhead or underfoot (lunar transits). The minor periods also see increased activity and occur when the moon is rising or setting. The strongest activity occurs during full or new moons, and the weakest during quarter or three quarter moons. This is indicated by the Action Rating.
