This is the view from a friend's cottage on Round Lake looking west from about the same place where Tom Thomson painted "The Canoe". Tom's dove gray canoe would have been pulled up on the shore to the right.
A squall line with thunderstorms had just passed Round Lake. The showers were over. Northwesterly winds were sculpting the clouds and leaning them to the southeast. Convection along the squall line gives regularly spaced light patches in the cloud base. Scud cloud stirred up by the blustery northwesterly winds were whipping along to the southeast.
