Equivalents 2

Some amazing skies these days, as fronts of cloud and rain pass through. This is another cloud photo which takes after Alfred Stieglitz' Equivalents series he shot from 1923 on. I last did a cloudscape back in August, hence this is my Equivalents 2.
It's also another lazy blip, as my car was in the garage all day, so this was seen and snapped as I drove home.
