Hydrologic Outlook issued June 20 at 3:30AM CDT by NWS Chicago IL

Effective: Sat June 20, 2026, 3:30 AM
Expires: Sat June 20, 2026, 4:00 PM

ESFLOT A steady soaking rain is expected Sunday afternoon and evening. The highest rainfall amounts are forecast south of I-80 where totals in excess of 2 inches are possible. Many rivers and streams across the region remain elevated from recent heavy rainfall. Thus, rainfall amounts of this magnitude will result in renewed rises on area streams and rivers, with some potentially topping flood stage. Uncertainty remains with where the heaviest rainfall amounts will occur. Anyone in or near flood prone areas should thus closely monitor later forecasts. This outlook will be updated by this evening.

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.
