A dry storm or a streak of cloud is a weather phenomenon. There is a technical term for it. The painting is reminiscent of others I have done call "Shaft of Sunlight" (also in this blog) and two paintings done in 2002-03 called "Intervention" one a study for the other. As is so often the case these have more than the obvious meaning but sometimes it takes a few years to see what that is. Let me know if you would like to see the 2002-03 paintings called "Intervention".
