It looks like the month of March has arrived in December. 

There have been rain amounts of 1.3 to 2.3 in the area. I know that is not much compared to the 3-4 inches of rain in central Iowa. However, it looks really wet in the area. There is water standing in the fields and water running...

Soybean harvest has been complete in northwest/north central Iowa for a couple of weeks. 

Corn harvest is wrapping up also. I would guess that there is about 15% of the corn that is yet to be harvested.
