I spent night at Wilber NE, but I was not sure, if weather would cooperate, so I woke up at 3 AM, and I drove to Wyoming. There was miserable foggy misty weather in the mid part of Nebraska. It was real "fun" to drive in fog. West Nebraska had good sky with clouds on the horizon. East Wyoming was cloudless. Great experience on Rd85 between Torrington and Lusk, it was gorgeous.
But there were clouds even in Wyoming. This guy made his composite from Yellowstone only so so , see https://apod.nasa.gov/apod/ap170822.html
