Hydrometeorological Forecast Discussion
NWS North Central River Forecast Center Twin Cities/Chanhassen MN
1104 AM CDT Sat Oct 21 2017


A cluster of showers and thunderstorms developed across Iowa
overnight, and spread northeast into Minnesota and Wisconsin this
morning. This brought between a quarter and a half inch of rain in
a couple of hours. Further east, a weak boundary allowed for some
light showers along a line from Illinois up into the lower
peninsula of Michigan, with only light amounts.

A cold front is poised to move through the region over the next
24-36 hours. The front was out in the Dakotas this morning and was
serving as a focus for showers and thunderstorms. This will all
spread eastward today and tonight, reaching a line from Kansas
City to Minneapolis this evening, and Chicago to St Louis by
Sunday morning. Rainfall associated with the frontal passage
should be less than an inch for most, but amounts of 1-2 inches
are possible across parts of Missouri into southern Illinois.

...Hydrologic Conditions...

River flows continued to slowly recede on the Minnesota River, the
upper portion of the Des Moines River, and the upper Mississippi
River above Lock and Dam 10. We are now down to 15 active forecast
points in Minnesota, Iowa, Wisconsin, and the UP of Michigan.

Minor flooding continued around Montivideo, MN due to controlled
reservoir releases.  No significant river flooding is expected
during the next five days.
