Looks like the focus for the heaviest rains is bumping northwest a little, favoring the northwest half of Iowa over the next week. Still may get 1"+ down this way but southern edge is trending this way.
If this model run of the ICON works out that 15-17" of rain forecast will go nicely with the 5-7" of rain that fell in the Des Moines area a few days ago.
Several models dumping 2-4" of rain over parts of Iowa later today and tonight. Hoping the sloppy seconds from that can deliver a good half inch in this area.
