...Precipitation...

High pressure over the Midwest will shift eastward. Low pressure
will approach southeastern Missouri tomorrow morning and Chicago
on Friday morning.

In the past 24 hours...around a tenth of inch of rain fell over
Wisconsin and southeastern Minnesota, and a tenth to half an inch
fell over lower Michigan.

In the next 48 hours...half an inch to an inch of rain is forecast
to fall over Indiana, eastern Illinois, southeastern Wisconsin,
and southwest lower Michigan.

Air temperatures will be much above normal for the next week.

...Hydrologic Conditions...

River levels remain elevated from ice jams on area rivers.
Moderate ice jam flooding continues along the Mississippi River
near Burlington, Iowa, along the lower Rock River, the Kankakee
River near Wilmington and the Iowa River near Marengo.

Rainfall over the past couple of days, ice jams, and ongoing and
forecast snowmelt may cause the Rock River near Moline, Illinois,
to rise near major flood levels tomorrow.  Minor flooding is
occurring or forecast on rivers in southern Michigan, northern
Indiana, northern Illinois, and eastern Iowa.

Ice appears to be moving on the mainstem Mississippi River,
causing river levels to fluctuate.  With warm temperatures, ice is
expected to flush through the system, and stages should return to
near open water conditions over the next couple weeks.
