Combining images for streaking cloud effect

When I was in Glacier National Park last week I took several images using my 15 stop neutral density filter.  This is one I particularly liked.

Later in the day I took a hike to a point I had never been to before. When I left the car there were no clouds, so I left my filter behind and just took a camera and tripod.

After spending some time at the point clouds formed and I wished I had carried my filter. I thought about it for a while and decided to take 40 images at 8 sec intervals, with the thought of combining them later. Here is the result.

Here is a video tutorial on the process.  I hope you can use this technique to add some creativity to your images in the future.
