ESFLOT Showers and thunderstorms are expected to develop this afternoon and tonight across northern Illinois and northwest Indiana with additional showers and storms expected Monday afternoon through Monday night. These showers and thunderstorms may produce heavy rainfall rates up to one inch per hour as they move east across northern Illinois and northwestern Indiana. Soil moisture across most of the area ranges from near average to slightly above average, which will have only a limited impact on runoff rates. While most areas will receive rainfall amounts around 1.0 inch, a narrow corridor may receive localized rainfall up to 2.0 to 2.5 inches from multiple rounds of showers and thunderstorms. Rainfall amounts of this magnitude will likely cause rises on area streams and rivers, some of which could reach or exceed flood stage. This outlook means that elevated water levels and potential impacts are possible, but not yet certain. Persons should closely monitor forecasts including the possibility of flood watches, warnings, and advisories. No additional outlooks are expected for this event unless the threat for heavy rainfall becomes more certain.
