With September here, many farmers in central Illinois have started harvesting corn.

That's a little bit earlier. But farmers like Dennis Wentworth of Downs says they're only harvesting their driest corn right now.

This week's cool weather has slowed the corn drying process.

Larry Huelskoetter farms near Beason in Logan County. And he's been pleasantly surprised by high yields so far. He expected a hot, dry summer might have burned some of his corn.

In many areas further south where more rain has fallen, farmers say they'll wait a little longer to get started.

University of Illinois crop expert Emerson Nafziger says warmer weather would speed corn drying and that may happen. Forecasters say temperatures should warm across Illinois early next week.
