#2039 "Killarney Cold Air Mass Cumulus"

The 2017 Southampton Art School Annual Adventure was carrying on the legacy of my friend and artist Jane Champagne. This was the fifteenth demonstration painting and the fourth of Day 4 of the Plein Air Paint Out. When the group arrived they set up at the cyclonic branch of the deformation zone beach so I moved to be with them. This was going to be a windy location with the westerly fetch of blustery winds off George Lake. It was more important to be with the group than to seek sheltered comfort. At breakfast I had pointed out that the isobaric gradient was really quite weak so I was hopeful that the winds would not be an issue. The slight anticyclonic curvature of those flat ridge isobars and the cold air advection overpowered the gradient wind and it was indeed windy and even a bit chilly.
I turned the small, smooth and slippery surface on edge to make a portrait format of the landscape. The same shoreline of George Lake can appear quite different when looked at in a different way. It is always good to step out of your comfort zone to see what might happen. Every painting is an adventure and an experiment to maybe learn something new.

With daytime heating the stratocumulus were becoming more vertical in the unstable cold air mass behind the cold front. It was chilly when the clouds intercepted the heating radiation from the sun. These cumulus were looming as they tumbled over the hills of La Cloche.
