I'm probably a poor judge of cloud altitude but I'd guess less than
5,000 and maybe as low as 2,000. This is what it looked like when I got
out there with the camera but it's not much like what it looked like a
couple of minutes before. The dark, diagonal edge at lower left is the
roof of my house. 24mm, f/5.6, 1/320 at ISO 400

I had a hard time believing it could change that fast. There were cloud
layers lined up diagonally as you see on the left. But the layers
looked like someone had cut up a blue/gray blanket into thin strips, cut
one edge with giant pinking shears (but with curved edge triangles) and
then laid the strips one over the other so only the wavy edges were
visible. All the cottony puffiness you see in my photo was either not
there or not prominent when I first saw it.
The first lightning bolt struck about 1/4 mile away just seconds before
I made this shot.
