...Precipitation...

Several areas across our region saw two to four inches of rain as
strong thunderstorms developed yesterday through early this morning.
The heaviest rain fell across central to southeast Minnesota, in
northeast Iowa, and across southern Wisconsin to northern Illinois
and northen Indiana, where a few locations reported four to five
inches of rain. Eastern North Dakota to northwest Minnesota had one
to two inches of rain.

Last night through early this morning showers and thunderstorms were
mainly scattered across the western half of lower Michigan to upper
Michigan, and across the north half of Wisconsin. Most rainfall totals
in these areas averaged a half to one inch, with a few reports in the
two to three inch range from the Green Bay area across Lake Michigan to
the Grands Rapids area.

In the forecast...scattered showers and thunderstorms will continue
generally along the front across Missouri, Illinois, and Indiana to
Michigan. Precipitation totals here will average around a quarter to
half inch.  Also thunderstorms will continue from early this morning
mainly across lower Michigan and northern Indiana where rainfall
totals will average near an inch, with locally higher amounts near
two inches.

...Hydrologic Conditions...

Heavy rainfall in the last 24 hours has caused localized flooding in
northeastern Iowa and southwestern WI. The Turkey River is expected to
rise to flood levels at Elkader Iowa and will see bankfull levels at
other locations. The Grant River at Burton WI is currently at moderate
flood levels, and other rivers across the region are seeing rises, with
many forecast to reach bankfull levels.

The Mississippi River remains at elevated levels along its entire length
within the NCRFC region. The river is at or near action stage at many
sites from Minnesota downstream through Iowa, Illinois and Missouri.

Multiple rounds of heavy rain in recent weeks have caused elevated flows
on many rivers across eastern North Dakota, Minnesota, western
Wisconsin, Iowa and Illinois. Locations that are already experiencing
high levels remain vulnerable to additional flooding.
