Death comes to us all. Life's but a walking shadow | Research indicates that it isn't just the yield loss due to the acute frost damage but cool weather dramatically reduces the rate of seed fill so you get smaller beans and lower yields. Even though the daytime temperatures can be quite warm if the nighttime temperatures falls below 50 deg F seed fill slows down. There was a considerable number of days in the critical seed fill period during Sept when that's exactly what happened.
The problem with plants is that they are on a physiological development schedule such that even if the weather warms back up the plants have moved beyond that critical period and can't go back and catch up.
To make matters worse I think the Dakotas and northern Iowa received some more much cooler weather just in the past few weeks.
Given that a very substantial portion of the increased bean acres is located in the area in question it'll be interesting to see whether their reduced yields offset the big yields being reported elsewhere. It is important to remember that those areas reporting big yields aren't the areas which necessarily have the most acres.
This might be some of what is behind the current soybean rally.

Frost damage to bean yields...
