Hydrologic Outlook
National Weather Service Chicago IL
1111 AM CDT Sun Mar 31 2024

...Locally Heavy Rainfall Possible Tonight through Monday night...

Showers and thunderstorms are expected to develop this afternoon and
tonight across northern Illinois and northwest Indiana with
additional showers and storms expected Monday afternoon through
Monday night.

These showers and thunderstorms may produce heavy rainfall rates up
to one inch per hour as they move east across northern Illinois and
northwestern Indiana. Soil moisture across most of the area ranges
from near average to slightly above average, which will have
only a limited impact on runoff rates. While most areas will receive
rainfall amounts around 1.0 inch, a narrow corridor may receive
localized rainfall up to 2.0 to 2.5 inches from multiple rounds of
showers and thunderstorms. Rainfall amounts of this magnitude will
likely cause rises on area streams and rivers, some of which could
reach or exceed flood stage.

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.

No additional outlooks are expected for this event unless the threat
for heavy rainfall becomes more certain.
