A storm comes in from the West.  It is September but really hot and humid the past few days.  I caught this in the early evening as the front came in – perfect timing.  A few minutes later and it was heavy rain with boring grey overhead.  I did not have my widest lens with me so I shot this as a panorama and stitched together 5 shots.
