...Precipitation...

During the past 24 hours showers and some embedded thunderstorms
moved across portions of North Dakota, Minnesota, Wisconsin,
northeastern Iowa, and Michigan.  Reports were generally 0.25" or
less.  However, there were reports of 1"-2" in the Upper Peninsula
of Michigan and central Lower Michigan where some isolated
thunderstorms formed.

During the next 24 hours up to 1.25" of rain are forecast over
northeastern Minnesota, the western Upper Peninsula of Michigan,
and northern Wisconsin.

Up to a quarter inch of rain is expected on Monday over Michigan
and Missouri, but Tuesday through Saturday of this coming week are
looking very wet across Minnesota, Wisconsin, northern Illinois,
northern Indiana, and Michigan.  7-day totals of 4"-6" cover
southern Iowa, northern Missouri, southern Wisconsin, northern
Illinois, and Lower Michigan.


...Hydrologic Conditions...

Due to the rainfall event June 22-23, parts of Lower Michigan are
experiencing significant flooding.  The primary focus of the
flooding is within the Saginaw River basin on the Tittabawassee
River and its tributaries.  The Chippewa River at Mt.Pleasant
crested yesterday at 14.8 feet, which was 1.8 feet above Major
Flood category.  This was the 2nd highest crest on record. Routed
high flows from the Salt, Chippewa, and Pine Rivers combined with
the Tittabawassee produced a Major flood at Midland as well.
Midland crested yesterday at 32.1 feet which was 4.1 feet above
Major Flood category and is also the 2nd highest crest on record.
All of this routed flow is expected to cause the Saginaw River at
Saginaw to rise above Moderate Flood category and crest around 19.8
feet the morning of June 27th.
