The paths that Polar Orbiting Satellites take around the Earth are predictable, and the prediction for next Monday, 21 August 2017, is shown above (image courtesy Rick Kohrs, SSEC). Note that Suomi NPP has an ascending orbit passing over the eastern part of the USA, from Florida to Michigan, at predicted times of 1830 and 1834 UTC on 21 August 2017. At 1832 UTC, Suomi NPP should be over the Great Smoky Mountains.
At the same time, the shadow of totality will be over eastern Tennessee as well, as shown below (From this site). Thus, Suomi NPP will be well-positioned to observe a snapshot (with excellent spatial resolution) of this eclipse, to complement the excellent temporal resolution of GOES-16.
