As a cold front sags south, showers and thunderstorms will move out of Wisconsin into northern Illinois later tonight, spreading across the remainder of northeast Illinois and northwest Indiana Wednesday. Rainfall totals from a quarter to half-inch will likely be common with locally greater amounts under stronger thunderstorms.
Chicago-area rivers in general continue a slow steady fall. Minor flooding is forecast into the weekend on the Illinois River from Starved Rock to LaSalle. The Fox River may be most affected by rain in the next 24 hours with minor flooding in the Harvard area and near bankfull conditions farther south maintained for a longer period. With anticipated rains, the remaining rivers should not experience any flooding problems.
River segments in flood are displayed in light green on the headlined map. The Hydrologic Summary of river stages and flood forecast issued earlier this Tuesday morning by the Chicago National Weather Service is provided below.
