Hydrometeorological Forecast Discussion
NWS North Central River Forecast Center Twin Cities/Chanhassen MN
1200 PM CDT Wed Sep 28 2016

...Precipitation...
An occluded low pressure system over the Great Lakes and trailing
frontal system brought wrap-around precipitation to the Arrowhead
of Minnesota, northern Wisconsin, and Michigan during the past 24
hours. The heaviest rain fell over the western Upper Peninsula of
Michigan and northwest Lower Michigan where up to 1.25 inches was
reported.

The occluded low pressure system over the Great Lakes will slowly
drop south and stall over Indiana and Ohio during the next 3
days.  During that time we are expecting generally up to a
half inch over Michigan, western Wisconsin, and western Illinois.
Between 1.5" and 2.5" are forecast over southern Michigan and
northern Indiana.  Heavier amounts are expected in the eastern
portion of that area.

...Hydrologic Conditions...
Significant flooding continues across much of eastern Iowa as last
week`s heavy rainfall works its way through the the tributary
watersheds and in to the mainstem Mississppi.

Major flooding continues along the Cedar River from Cedar Falls
and on downstream. Stages are falling at Cedar Rapids but levels
are expected to remain above flood stage until early next week.
Major flooding is imminent for communities further downstream on
the Cedar, and on the Iowa River all the way to the Mississippi
River confluence.

The Wapsipinicon River has crested at Anamosa and routed flows
will cause major flooding at De Witt in the next couple of
days.

Moderate or higher flood levels are forecast for much of the
Mississippi River downstream of Dubuque, Iowa. Major flooding is
forecast from Lock and Dam 17 at New Boston downstream through
Burlington. The crest isn`t expected to reach Dam 19 at Keokuk
until early October, and will make its way downstream with flood
levels expected to continue in Missouri in to the following
week.
