Forecasters expect Isaac could slide into Illinois, Missouri, Indiana, Iowa and Ohio as early as Friday - dumping as much as 12 inches of rain on the region. But the storm is moving slowly – and the track has moved just a bit south.

"It will be a little bit later before it actually affects portions of Illinois, probably Saturday night or Sunday. So if you have any plans for Saturday, I think you're OK, but Sunday, that's when we could get some clouds and maybe a couple of showers," ABC7's Meteorologist Jerry Taft said.

That kind of deluge is usually welcomed by farmers, but it could actually work against them by making fields too muddy for harvesting equipment. The Midwest has been under a severe drought for much of the summer.

Kenneth Metcalf farms nearly 600 acres of corn and 120 of soybeans near Mechanicsburg in central Illinois, and he's also concerned about the potential for strong winds. He says the corn isn't very stable and 50-plus-mile-per-hour winds would just break the stalks off.
