We had a nice thunderstorm a few day ago, just as the sun was setting.
First, it looked like this: some nicely underlit mammatus; the kind of clouds associated with severe thunderstorm turbulence.
I live on the side of a small mountain; the irregular landforms here means that we don't often get the wide sheets of mammatus you see in the midwest. In fact, it's unusual to see any here.
On the plus side, we only get one or two tornadoes a year, as well.
I snapped a few more shots as the light angle changed...
Some scud blew over, making it too dark for cloud photos for a while. But when the scud blew away, the sky turned salmon:
The color shifted slowly...
... but held long enough to make for a memorable moment.
