There are several website that I started using in the past trading week:

1.  CME Group. http://www.cmegroup.com/

This user-friendly website gives information on a overall glimpse, not in too much details though. But it does not have to have a general idea first to make further movements.

2.FOREXPROS   http://www.forexpros.com/news/commodities-news

On this website, I found it usually contain an “weekly outlook” article to predict the next week’s market.

http://www.forexpros.com/news/commodities-news/grain-futures—weekly-outlook:-november-5—9-240264

In this particular journal, it not only summarized what happened to the key grain commodities last week, it also predicts the future price pattern of the following week with a lot of detailed info. For example, it calls for attention for us to look at the USDA scheduled release on its updated crop estimates on November 9. It also offers how weather conditions are related.
