Hydrometeorological Forecast Discussion

...Precipitation...

During the past 24 hours showers and thunderstorms moved across
southern Iowa and central Illinois dropping less than 0.75" of
rain.  Rain showers over the eastern Upper Peninsula of Michigan
and northern Lower Michigan generated up to 1.7" of rain in some
areas.  Lighter rain of a third of an inch or less fell over
northeastern Minnesota, northern Wisconsin, and the western Upper
Peninsula of Michigan.

The next five days are going to be wet across the NCRFC Service
Area.  During Wednesday and Wednesday night up to 1.25" are
forecast over southwestern Minnesota and northwestern Iowa.

During Thursday and Thursday night strong storms are forecast
across southeastern Iowa, eastern Wisconsin, the eastern Upper
Peninsula of Michigan, and northern Lower Michigan.  Forecast
amounts could be 2" or higher in some areas.

On Friday and Friday night strong storms are expected along the
Iowa/Missouri border and across central Illinoia and northern
Indiana.  Again, amounts could be as high as 2" or higher.

Over the weekend the region around the southern end of Lake
Michigan could see up to 2.5" or more.


...Hydrologic Conditions...

Water levels continue to recede across the NCRFC area. Only one
location remains above flood stage: Saginaw Michigan.

Elsewhere, elevated river levels are seen in parts of the
Menomonie and Wisconisin river basins, thanks to significant
rainfall in those areas from late last week into the weekend.

But this trend looks to turn around again with the forecast rain
described above over the next 5 days. The highest liklihood for
widespread flooding looks to be from Missouri and Iowa, into
northern Illinois. We will continue to monitor.
