All eyes are on already swollen area rivers Tuesday as rain begins to fall across the Chicago region and flood warnings remain in effect on several area waterways.
In addition to the rain that has begun to overspread the area, temperatures are expected to drop and we may even see some light snow showers, the National Weather Service said.
As a result of last week’s storms, flood warnings continue for the:
— Des Plaines River in Lake and Cook counties;
— Fox River in Kane, McHenry, Kendall and LaSalle counties;
— Kankakee River in Porter, Lake and Newton counties in Indiana; and
— Iroquois River in Iroquois County.
Flooding continues along the Des Plaines and Fox rivers, according to the Weather Service, and an additional half to three-quarters of an inch of rain is possible across northeast Illinois on Tuesday afternoon and evening.
River forecasts indicate this rainfall would slow the rate of the decline of water levels in the rivers, and if there is more than three-quarters of an inch of rain, or intense rain in a short time, it could result in rivers rising again.
The showers and possible thunderstorms forecast for Tuesday are expected to fall mainly south and southeast of the Chicago Metro area, the weather service said. Showers are likely into the evening, and as temperatures fall, there could be a mix of light rain and even light snow showers after midnight. No snow accumulation is expected, though temperatures will dip into the low 30s.
Wednesday should start out partly sunny, but there is a 40 percent chance of light rain and light snow after midnight again. Lows are expected to fall into the mid 30s late Wednesday.
The weather service continues to warn area residents that if they encounter a flooded roadway to turn around and find an alternate route.
