Hydrologic Outlook issued January 8 at 1:57PM CST by NWS Chicago IL

Effective: Thu January 8, 2026, 1:57 PM
Expires: Fri January 9, 2026, 12:00 AM

ESFLOT Waves of showers and thunderstorms are expected this afternoon and evening across portions of northeastern Illinois and northwestern Indiana. The highest rainfall rates are expected this evening as atmospheric moisture increases to near record levels for January and a line of showers and thunderstorms moves through the area. Small isolated corridors may receive rainfall in excess of 1-2 inches, especially in areas where storms orient in a more southwest to northeast direction. Rainfall amounts of this magnitude sometimes cause localized flooding of streams and poor drainage areas during the winter months. Areas with streets, drainage ditches, and stormwater drains impacted by late fall and early winter vegetation debris may be especially susceptible to flooding. This outlook means that elevated water levels and potential impacts are possible, but not yet certain, based upon the latest forecasts. Persons with interests along area streams and rivers should closely monitor the latest forecasts. In addition, ensure that nearby stormwater drains and ditches are cleared of debris.
