Hydrometeorological Forecast Discussion
NWS North Central River Forecast Center Twin Cities/Chanhassen MN
1122 AM CST Tue Jan 23 2018

Minor flooding is being observed through out southern Wisconsin,
lower Michigan, northern Indiana, northern Illinios and Iowa.

Intense rainfall, snowmelt and runoff on frozen ground created
rapid river rises. While a good portion of the snowpack had been
lost from recent warmer weather a new round of snow was received
mainly for Minnesota and Wisconsin.

River forecasts routinely incorporate 24 hours of QPF from
April 1 to September 30 and 48 hours from October 1 to March 31.
