Approaching Thunderstorm

Does this look like the end of the world, or what!  It was pretty exciting around here with thunderstorms day after day, in the last two weeks.  I was headed into the grocery store and the sky was a bit dark in the northwest, but no big deal.  It didn't take me long to shop, and when I came out this is what I saw.  I only had a couple of minutes to grab a few frames, and then the rain began to fall.  I just made it back to the car, unscathed.  Thunderstorms really are magnificent!
