What will the skies be like on the day and time of the eclipse?

Trying to predict the weather a year in advance is no easy task...however predicting sky conditions is a bit easier. We have archive images from weather satellites that show definite patterns in cloud cover over the Earth. I assembled a number of images from the GOES weather satellite spanning 2006 to 2015 on 21 August at the approximate time of the eclipse of 21 August 2017. It seemed that in 2013 there was a small area of cloud cover during eclipse time. The other years proved to be cloud free. You will notice what looks like a light grey area as well as obvious clouds. The light grey is actually water vapor but not clouds. The satellite sensors detects into the near infra red region of the spectrum which detects water vapor. I will post the 21 August 2016 image when it is ready and we can compare the prediction to the latest weather satellite image one year out.
