The NWS’s Weather Prediction Center has issued a Level 3 out of 4 risk for excessive rain across parts of northeastern Iowa, southern Wisconsin and northwest Illinois for Sunday.

Heavy rainfall of 2 to 4 inches has already fallen across this region over the last 24 to 36 hours, Brink said.

A flood watch is in effect across parts of southern Minnesota, northern Iowa, much of southern Wisconsin and northwestern Illinois.

Another 3 to 5 inches of rain are possible in parts of northern Iowa and southern Wisconsin through Monday morning.

“The threat for flooding will remain as yet another round of heavy rain is forecast later tonight, which could lead to a higher end flood event if the rain trains over the same areas that are getting soaked this morning,” Brink said.
