Chicago Early Call

First calls on Chicago this afternoon are that corn futures are expected to open 6 to 8 lower; soybeans 10 to 15 lower; wheat 2 to 7 lower.

An intersting session lies in store ahead of a long weekend in the US where traders may book some profits as weather models are sending out conflicting messages for the Midwest next week.

On a market like this anything between limit up and limit down wouldn't surprise. Chances are whatever it does tonight it'll do the opposite on Monday!
