Hydrometeorological Forecast Discussion
NWS North Central River Forecast Center Twin Cities/Chanhassen MN
0110 PM CDT Sat Aug 19 2017

Scattered showers and a few thunderstorms brought areas of
precipitation to every state in the NCRFC forecast area.  Rain was
most widespread over southern and western Minnesota and southward
into central Iowa, and across northern lower Michigan. In other
areas the rain was more widely scattered and light, generally less
than a tenth of an inch. The heaviest rain was around Park Rapids,
MN which reported around 1.7 inches, and over southwest Minnesota
where reports were between two thirds of an inch and two and a
half inches between Fairmont, MN and Ortonville, MN.

During the next 24 hours...scattered light rain is expected in
association with a Canadian cold front trailing through northwest
Minnesota to a low in north-central Nebraska. A warm front
associated with that low will be pushing into western Iowa to
bring a chance of rain there.  The period Sunday morning through
Tuesday morning looks wet for the Middle Mississippi River Valley
with rain expected along and ahead of the Canadian cold front
which my Monday morning should stretch from the Great Lakes region
southwest to the Central Plains states.  Current model runs
project the heaviest rain over Iowa, where storm totals of five or
more inches are possible.

...Hydrologic Conditions...

There is currently some bankfull rises throughout the Minnesota
River watershed due to heavy rains Wednesday evening.  Otherwise
there is no significant flooding currently occurring within the
NCRFC service area.  There is potential for significant flooding
across parts of Iowa with the forecast rainfall expected Sunday
night through Tuesday.
