Thanks tallpine!

Great addition and maybe the most exciting market out there right now. After years of being dead, corn has come to life. 

Small changes in the forecast the next few weeks might mean 10c+ moves on some days. Big changes and it could be 20c in a couple of days(like we saw yesterday from the highs on Sunday Night).

The last, 18z US model has a huge rain for IA at the end of this week/this weekend. The air aloft is going to be very warm with this cold front and some models keep the atmosphere capped with no rains as far south as IA. 

A huge rain with that event in IA over the weekend and corn opens -10c on Sunday. If IA misses and there are no rains behind it for over a week, corn opens +10c on Sunday.

Days 4-5 below:
