...Heavy rainfall and localized flooding possible late Tuesday into
Wednesday...

Waves of showers and thunderstorms are likely late Tuesday into
Wednesday. Some storms may produce rainfall rates in excess of 1 to
2 inches per hour, which could lead to localized flooding. The
locations with the highest risk of flooding are somewhat uncertain.
The highest probability of heavy rainfall is generally along and
south of I-80, but drought conditions worsen toward Livingston,
Ford, Iroquois, and Benton counties. Drought conditions increase the
rainfall rates needed to cause flood impact. Closer to the Chicago
Metropolitan Area, lower rainfall rates would be required to cause
flood impacts, but the probability of heavy rainfall there is lower.

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.
