Couple of nice looking storm cells out there tonight. One near Rose City, Michigan, south of Huron National Forest, and one northwest of London, Ontario.

The WPC has a moderate chance for excessive rainfall across southeast Iowa, nw Illinois, and southern Wisconsin this weekend.  The forecast has widespread 3-5+ inches across that area.  The discussion even mentions isolated 9" totals are possible.  DVN thinks 10" is possible.

Yeah I'm definitely worried for some potentially significant flooding somewhere in S or SW WI. While it hasn't been as wet as most of IA over the last 30 days, it's still been wet enough to cause concerns even without some of the more extreme totals that models have put out. SW to NE is a bad direction for precip maxes in regards to the drainage network in this part of the state. And 6-10 inches of rain in a night would be very bad news for really any drainage around here.

CAMs (18Z 3K NAM/0Z HRRR) aren't too enthused about much more than garden variety tomorrow. EHI is pretty low. SPC may have been over-optimistic expanding the slight risk into all of S. WI and adding a 2% tornado contour.
