...Increasing concern for flooding Monday through late Tuesday...

An unseasonably warm and moist air mass will overspread the region
early next week with several rounds of showers and thunderstorms
expected. Through early Wednesday, expect area-wide precipitation
totals of an inch or more with some locations possibly seeing 2
to 4 inches of rainfall. Heaviest rainfall is favored over far
northern Illinois on Monday and will shift into east-central
Illinois and northwest Indiana on Tuesday.

Grounds are still frozen over much of the area and will result in
rapid runoff. In addition, some areas in northern Illinois may
still have snow on the ground and additional melting will compound
runoff from heavy rainfall. Expect rises on area rivers and
streams, and flooding will be a distinct possibility. Stay tuned
to the latest forecasts for updates.
