...Precipitation...

A low pressure system over Arkansas will move to Indiana by
tomorrow morning while a trough of low pressure develops over
the High Plains.

In the past 24 hours...light rain fell over eastern Missouri and
western Illinois with totals ranging from a trace to half an inch.

In the next 48 hours...half an inch to an inch of rain is
forecast for Indiana, eastern Illinois, and southwestern lower
Michigan.  Lighter precipitation will fall over the remainder of
the NCRFC service area.  The precip over northern Minnesota and
northwestern Wisconsin will likely be a wintry mix.

Above normal air temperatures are expected for the next week or
two.

...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 may cause the Rock River near
Moline, Illinois, to rise near major flood levels later today.
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.
