Hydrologic Outlook
Hydrologic Outlook ILC007-031-037-043-053-063-075-089-091-093-097-099-103-105-111-141- 197-201-INC007-073-089-111-127-051800- Hydrologic Outlook National Weather Service Chicago IL 209 PM CST Thu Dec 4 2025 ...Risks for River Ice Formation and Isolated Ice Jams will continue the next Few Days... Very cold temperatures tonight will be favorable for additional ice on rivers and tributaries. Reports from river ice spotters and river gauges indicate that isolated areas of heavy river ice coverage have already developed. While not likely, ice jams will be possible in isolated areas along the Rock, Fox, Des Plaines, and Kankakee rivers. Ice jams may cause rises on area rivers with little warning. Despite warmer temperatures expected by this weekend, widespread melting of river ice is not expected. As a result, most river ice that develops this week will likely remain in place through early next week. 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 product may be updated by tomorrow afternoon. $$ WSL/Borchardt
