Hydrometeorological Forecast Discussion
NWS North Central River Forecast Center Twin Cities/Chanhassen MN

...Precipitation...

A large storm complex spread showers and thunderstorms across a
wide area overnight from the Dakotas and Plains states, into
Minnesota and Iowa. Rainfall was heaviest from western Minnesota
into adjacent portions of southeastern South Dakota and northwest
Iowa. Amounts between 1.50 and 2.50 inches were common in these
areas. By 12z this morning the rain had pushed as far east as a
line from Baudette MN to the Twin Cities and Quad Cities.

This storm complex will continue to move east today. Rain and
thunderstorms will spread east across the Great Lakes states,
while a trailing cold front will light up with activity,
stretching from Wisconsin, back through Iowa and Nebraska. As the
front sags south and east, rain will also impact northern Missouri
into Illinois by Thursday.

Beyond that, it continues to look rather wet, especially across
the corn belt. The front will meander around the Iowa/Missouri
area, as several other disturbances move through the Upper
Midwest. Repeated showers and storms could end up dropping a total
of 4-5 inches by Friday in that area, with amounts up to 2 or 2.5
inches stretching into Wisconsin and Michigan.

...Hydrologic Conditions...

Overall, water levels continued their decline up through this
morning across the NCRFC area, with no forecast points above flood
stage. But with the weather system now moving through, and periods
of rain expected over the next several days, that trend is not
expected to continue. Already a few locations are showing rises
due to forecast QPF over the next 24 hours. As rain gets on the
ground, and we add more rain over the next few days, we expect
more forecast groups to get active.

The focus area through Friday seems to be from the Iowa/Missouri
border region, up into northern Illinois, Wisconsin, and Michigan.
As always, we will monitor the situation and issue forecasts as
necessary. if you have any specific concerns, feel free to contact
us.
