Hydrologic Outlook
Hydrologic Outlook ILC007-031-037-043-053-063-075-089-091-093-097-099-103-105-111-141- 197-201-INC007-073-089-111-127-131800- Hydrologic Outlook National Weather Service Chicago IL 357 PM CST Fri Dec 12 2025 ...River Ice to Expand This Weekend due to Very Cold Temperatures... Recent reports from river ice spotters and river gauges indicate that some melting of ice has occurred over the last few days, but isolated areas of heavy river ice coverage continue. Very cold temperatures this weekend will cause river ice to expand in coverage. Ice jams will be possible in isolated areas along the Rock, Fox, Des Plaines, and Kankakee rivers into early next week. Ice jams may cause rises on area rivers with little warning. Warmer temperatures may return to the area by late next week, which could begin a slow melt of river ice. This outlook means that elevated water levels and potential impacts are possible, but not yet certain. Persons with interests along area rivers should closely monitor the latest forecasts. This outlook may be updated by tomorrow afternoon. $$ WSL/Borchardt
