Hydrometeorological Forecast Discussion

...Precipitation...
During the last 24 hours...continued circulation around low
pressure over Ontario, Canada brought mostly light rain to the
northeast half of North Dakota, the northern three quarters of
Minnesota, all but southwest Wisconsin, upper Michigan, northern
and southeastern lower Michigan, and scattered portions of
northern Indiana, Illinois, Missouri and Iowa.  The heaviest
precipitation was along the Wisconsin shore of Lake Michigan where
half to one inch amounts were common and one and a half to two
inches fell just north of Milwaukee, WI.  Half to two inches fell
around portions of the Detroit, MI metro area while two thirds to
one and two thirds inches fell around Traverse City, MI.  A
quarter to three quarters of an inch of rain fell over northeast
Minnesota and upper Michigan.  Elsewhere most reports were less
than a tenth of an inch.

During the next 24 hours...wrap around moisture associated with
the occluding Ontario, Canada low will continue to produce light
rain showers over portions of eastern North Dakota, Minnesota,
Wisconsin, upper Michigan and northern lower Michigan.  Showers
along an associated cold front moving through central Illinois and
Missouri will provide a chance of rain to the right of a Columbia,
MO to South Bend, IN to Flint, MI line. The heaviest rain amounts
of up to a half inch should occur over upper 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 Bellevue (L & D 12).
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
