Summer rains are coming, and that's a good thing. It's been really dry this year and Powell Lake where my cabin floats is at a record low.
An old weather saying, "mackerel sky, more wet than dry," comes to mind. Clouds here in Coastal BC offer a beautiful display in addition to their forecasting properties. I'm constantly taking pictures of the sky in all of its moods.
A mackerel sky is made up of altocumulus clouds, indicators of moisture and instability in the atmosphere. The clouds ride at intermediate levels from 2400-6100 metres (8000-20,000 feet). Altocumulus clouds often precede rain showers or snow flurries.
"Mackerel sky" is the common name for these clouds because they look like scales on a mackerel. -- Margy
