Hydrometeorological Forecast Discussion

...Precipitation...

Widespread rain fell across the NCRFC region during the past 24
hours.  The heaviest rain fell from Missouri and into Illinois
where between an inch and three inches were reported.  Southern
Wisconsin also received over an inch of rain.  The remainder of
the NCRFC area received from a few hundredths to a quarter inch.

An inch to inch and a half of rain is forecast across northwestern
Minnesota... southern Michigan and northern Indiana today.
Lighter rain will fall across most of the remainder of the region
except for Iowa and the western half of North Dakota.

Rain will continue across most of the region into the middle of
next week.  Daily rainfall totals are expected to be less than a
half inch for most places... although thunderstorms could drop
heavier amounts.

...Hydrologic Conditions...

About sixteen forecast points are currently at or above
flood stage across the central portion of the NCRFC area.

Over 40 forecast locations are considered active at this time,
yet below flood stage.  These locations are located in Iowa,
northern Indiana, Minnesota, Wisconsin, Illinois, Michigan,
and Missouri.

A large portion of the NCRFC area has very wet soil
conditions for this time of year.  The high soil moisture is
also demonstrated by the USGS Daily Streamflow Conditions map
which shows flows at river gages in these areas generally at the
76th percentile or higher.

The forecast precipitation for the next few days is expected
over some of these wet areas in Wisconsin, Iowa, Illinois, and
Missouri.  If the rainfall forecast verifies we may see some minor
flooding or worse if rainfall amounts are higher than expected.

The U.S. Drought Monitor shows only isolated areas in the NCRFC
region with abnormally dry intensity.  These dry areas are the
far northern portion of the lower peninsula of Michigan, the far
southeastern corner of Wisconsin and south central Iowa.  The
majority of the NCRFC area is not impacted by any drought
signatures.
