Early call on Chicago

Soybeans seen opening up 10-12c, corn up 2-4c and wheat mixed. More aggressive thunderstorms than expected overnight in the Western Corn Belt helped to push eCBOT futures up slightly. Expect a great deal of price volatility this week, however.

Wheat can't seem to buy a rally at the moment with bullish news ignored or quickly brushed off. The main focus of traders' attention here is that a much bigger crop world-wide is not very far away.
