I had a quick play with the levels and the midtones / shadows / highlights and came up with this. I am by no means an expert though and am still learning. I expect others on the forum will be able to do a far better job.
To make it look even better you'd need to spend more time selecting the dark section of the shot at the bottom using the magnetic lassoo tool or the magic wand tool, then tweak the levels when you've got all those bits selected. It will bring the detail out in that section of the shot without bleaching out the moody sky, as my rather hasty effort above has done!
