Dark Dawn

A warm conveyor belt associated with an approaching low pressure area was pushing northward across the Oak Ridges Moraine. Low level moisture moving with the flow was still dark while the sun illuminated the higher level sky. This low level cloud will dissipate quickly under the August sun but at dawn it looked really dark and dangerous. It wasn't but you really have to be a meteorologist or an experienced weather keener to figure it out. This sky meant that southern Ontario would get into the hot and humid weather again until the next cold front came along with thunderstorms. The cumulonimbus arrived just after I finished the painting the next day.
Note that the next day was Thursday August 20th and the tornadic supercell outbreak across Southern Ontario....
