Hydrometeorological Forecast Discussion

...Precipitation...

In the last 24 hours as the cold front moved through much of the
NCRFC area widespread rain was observed. The heaviest band of
showers was reported from northern Missouri up into Iowa and
western Wisconsin. Accumulations were generally a half an inch
to over 2 inches. Trace amounts to a few tenths on the backend
of the cold front.

In the next 24 hours the front moves into eastern Wisconsin,
eastern Illinois and Michigan. Several bands of rainfall are
expected especially over Michigan. Over the course of the
next few days rainfall amounts could reach up to 5 inches
in some locations.

...Hydrologic Conditions...

No significant river flooding is expected during the next five
days... though lower Michigan will need to be watched closely. If
we receive more rain than anticipated, the 72 hour max for
example, then we could possibly see some significant flooding in
Lower Michigan.

We now have 25 active forecast points with the addition of several
in lower Michigan, due to the QPF noted above. Some of the
points in lower Michigan could rise above minor flood levels in
the next two days with 48 hours of QPF. Northern Lower Michigan
has been relatively dry over the 30 days while the southern half
has been very wet.

Minor flooding continued around Montevideo, MN due to controlled
reservoir releases on the Minnesota River.

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.
