WAUNAKEE, Wis. (SPECTRUM NEWS) -- The Wisconsin weather throws another curve ball for farmers across the state. 

According to the most crop report from the USDA, last week's overnight lows in the 20s basically ended the growing season for most farmers. The corn harvest for grain is about 15 days behind the average, and the snow on Halloween has led to more uncertainty during this crucial harvest season.

“The weather can still turn  and we can get some nice sunny days that will dry the crop down, but what they will have to do is harvest it, then dry it and that just adds to the expense of producing corn and soybeans,” says Joe Lauer, an Agronomy Professor at UW-Madison.

Corn farmers like to harvest the crop at 25% or less moisture but currently, the crop is running between 25% to 35% moisture. Lauer says this has more of an impact on grain- for export and ethanol.
