Clearing Storm at Sunset

I was excited when I saw this storm front coming in at sunset over Rockport Harbor. But as soon as I began to photograph it I noticed that the sky was going to be washed out. What do you do now? A digital blend that's what. Even though things were moving a little here and there I was able to make a nice shot by blending the sky, which was about 2-3 stops brighter than the foreground, with the lobster boats. Nice effect which closely resembles using a split ND filter.
