The Iowa Caucuses will be held on Monday, February 1. The weather looks like it will be just fine for the middle of winter during the day. But snow is forecast to start falling at night, perhaps an accumulation of 1 to 3 inches.
A couple of inches of snow won't be a big deal in Iowa, but it may keep some caucuses goers at home.
Donald Trump gains with a large turnout. If the snow starts to fall early enough, it will likely be a slight advantage for Cruz.
