Strong low pressure will shift northeast across northern Illinois into lower Michigan tonight into Monday. A surge of moist air from the southwest will continue to feed into southern Wisconsin tonight. Moderate to heavy rainfall will continue across the area this evening into the overnight hours. Due to the first round of heavy rainfall Saturday into Saturday night across the area, with the saturated soils, and the expected heavy rainfall tonight, a Flood Watch is in effect for all of southern Wisconsin.
The heavy rainfall will lead to many rivers exceeding bankfull and flood stage across the area.
