Weather seems to be the driving force between the market movements this time of year. Argentina's weather influenced the soybean market last week and more rain is expected in Buenos Aires on Tuesday and Friday.

Export sales gave boost to market last week, watching to see if buying continues this week.
Tax bill expected to be signed before Christmas. We'll be watching to see if market enthusiasm reaches commodities.
