Hydrometeorological Forecast Discussion

...Precipitation...

During the past 24 hours up to 1.25 inches of rain fell over
eastern Illinois and central Indiana.  Up to a half inch fell over
southern Wisconsin, eastern Iowa, southwestern Michigan, and
northern Illinois.

During the next two days we are expecting up to a half inch of
prcipitation over Lake Superior and surrounding basins.  The
precipitation should fall as snow over the Arrowhead of Minnesota
and rain elsewhere.

Higher than normal temperatures are expected across the North
Central U.S. through early next week when temperatures will fall
below freezing over much of the NCRFC service area for awhile.

...Hydrologic Conditions...

Water levels remain elevated from ice jams on area rivers.
Major flooding is occurring on the Mississippi River near
Burlington, Iowa due to an ice jam.

Moderate ice jam flooding continues on the Iowa River near
Marengo.

Rainfall over the past few days, ice jams, forecast rainfall,
and ongoing and forecast snowmelt is causing the Rock River near
Moline, Illinois, to rise above major flood levels.
Upstream of Moline, the Rock River at Joslin is near crest about
two feet above moderate flood levels.

Minor flooding is occurring or forecast on rivers in southern
Michigan, northern Indiana, northern Illinois, southern
Wisconsin 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.
