Hydrometeorological Forecast Discussion

...Precipitation...

A low pressure system centered over southern Lake Michigan will
continue moving northeastward, while a temporary ridge of high
pressure builds over the Midwest. A new low will approach
southeastern Missouri on Thursday morning.

In the past 24 hours...the southern two-thirds of the NCRFC
service area received a mix of rain, sleet, freezing rain, and
snow.  Water equivalents ranged from a few tenths to 2 inches over
northern Illinois. The heaviest precip fell in a band from
southeastern Iowa to southwestern lower Michigan.

The Upper Midwest should stay relatively dry over the next 48
hours.

Air temperatures should continue to be above normal for the next
week or two.

...Hydrologic Conditions...

River levels remain elevated from ice jams on area rivers.
Moderate ice jam flooding continues along the Mississippi River
near Burlington, Iowa, and minor flooding is occuring
along the Rock River near Joslin, and the Kankakee River near
Wilmington.   An ice jam caused the Iowa River near Marengo to
rise above moderate flood levels early this morning.

Rainfall over the past couple of days, and ongoing and forecast
snowmelt may cause the Rock River near Joslin, Illinois, to rise
above moderate 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.
