Awesome Cloud - sort of

I'm on my way back into NYC to then continue on to the airport and head back to San Francisco. This cloud and the light looked beautiful. However now I'm just past the cloud and it looks darkish and like thunderstorms won't be far behind.... Not good news for airport delays.

Kudos once again to the iPhone as the train must have been traveling at least 85mph at the time I started taking the series of photos. Top left corner I couldn't get the correct angle without being cutoff by the angle of the window.

Update -Five minutes later now it is pouring down rain....
