...Precipitation...
A strong area of low pressure moved from Iowa on Tuesday, through
lower Michigan by early Wednesday. Ahead of this system, numerous
showers and thunderstorms were seen, and some dropped quite a bit
of rainfall. A band of 1 to 2 inches of rain fell from northern
Illinois and Indiana, into southern lower Michigan. Within that
band there were some reports over 3 inches along Interstate 80
from Joliet IL to near Gary IN. Convection also impacted areas
from Missouri into southern IL, where amounts from a half-inch up
to 1.70 inches were reported. Further to the north where more cold
air was in place, light snow accumulations affected areas from
eastern SD, across MN, and into northern WI and the U.P.  Snow
reports of an inch or two were received, with water equivalent
generally less than a tenth of an inch.

Light precipitation, mainly in the form of snow, will continue
from Wisconsin through Michigan today, perhaps also impacting far
northern Illinios and Indiana. Accumulations look to be light for
the most part.


...Hydrologic Conditions...

Due to snowmelt and rainfall, moderate flooding is possible
next week on the Mississippi River around Lock and Dam 18.

Elsewhere, minor flooding is occurring or expected in
eastern Iowa, Wisconsin, Michigan, northern Indiana, Illinois,
and along the Red River of the North.
