Cold temperatures could mean trouble for crops?

The United States has seen its' worst drought in over fifty years and the effects have been felt throughout.  Last night brought the first flurries of the year and the combination of cold temperatures and a very dry summer may equal trouble for US corn and soybean crops.  According to the US Department of Agriculture, the harvesting of the nations wheat crops are complete and 94% of the corn crops have matured; 85% of soybean crops have matured as well.  Though it would seem that the fairly early frost would cause issues for America's farmers, it seems the majority of crops have matured fully and/or have been mostly harvested at this point.  While we may not be enjoying the change in seasons, it seems there is minimal concern for our food crops.  Follow the link below for a time lapse video of crop harvesting during a drought.  Harvest Video
