Hydrometeorological Forecast Discussion
NWS North Central River Forecast Center Twin Cities/Chanhassen MN
1130 AM CDT Sun May 28 2017

During the last 24 hours, rain fell over the northeast half of
North Dakota, northern Minnesota, upper Michigan, Wisconsin, much
of Iowa, far northern and southern Illinois and all but northeast
Missouri.  The heaviest precipitation...between half and one and
three quarters inches...fell mostly south of I-64 in Illinois and
I-70 in Missouri.  Another band of quarter to three quarters of an
inch fell from southwest Iowa northeastward to Milwaukee, WI.
Otherwise most reports were less than a tenth of an inch.

During the next 24 hours, rain is forecast over the NCRFC forecast
area to the right of a line from Cape Girardeau, MO to Champaign,
IL to Moline, IL to Eau Claire, WI to Aberdeen, SD to Williston,
ND to Bethune, SK.  Heaviest rainfall amounts are forecast over
northern lower Michigan where half to one inch amounts are
expected. For the period Monday into Tuesday morning, mostly
light showers are forecast for North Dakota, northern Minnesota,
northern Wisconsin, upper Michigan and northern lower Michigan.

...Hydrologic Conditions...

Significant flooding continues on the lower Illinois River at
Havana and Beardstown Illinois for the foreseeable future.

The Mississippi River is near crest at Dubuque (L & D 11).
As the crest travels downstream there will be moderate
flooding along the Illinois-Iowa border portion of the
Mississippi River all the way down to Burlington, Iowa.

The Mississipi River will also have minor flood stage impacts
further downstream along Missouri and southern Illinois. Crests
are expected in a week or so. The COE will have no control of
the river for some time.

Another notable location with moderate flooding is Cosperville on
the North Branch of the Elhart River in northern Indiana.

For much of the NCRFC area soils are saturated and rivers are high and
therefore vulnerable to any significant rainfall event.

forecasts, precipitation and all hydrometeorological information
