The sunset sky told the bedtime story of the warm conveyor belt. Rain was on the way. The col in the altocumulus deformation zone was directly west of Singleton Lake. The cyclonic companion with more altocumulus cloud and positive, upward vertical velocity was to the north. The anticyclonic companion with more stratus cloud and nil vertical velocity was to the south. The Langmuir streaks of cirrus were higher and neatly spaced. It is not often that this much meteorology can be witnessed in one collection of clouds. A pair of jets were headed for Europe. They would be enjoying a bit of a tail wind with the warm conveyor belt and probably arrive a bit early. The showers arrived at 4 am the following day. I did not wait up for it to arrive - after all I was sleepy. There was more continuous rain further to the north. The heavier convective cells were mainly to the south and Singleton was on the northern edge of those.
Tom Thomson disappeared on this day in 1917 - July 8th. The history of his art and premature departure was another story that I used to tell especially on canoe trips. Tom was a weather fan and this sky would have intrigued him greatly. He would most certainly have painted it as well.

I wanted this painting to be full of energy and life while remaining accurate from a meteorological perspective.
