This is the sky over Great Cove and our dark North Field last night, as the sun sets in the west and the temperatures fall.
This is of the same area this morning, as the sun rises in the east to meet the frosted field and islands.
Once again, the mariner’s mnemonic was right:
Red sky at night, sailors’ delight,
Red sky at morning, sailors take warning.
This couplet usually proves true for the middle latitudes, meteorologists say. Red sky in the evening often means that the reflected sunlight is coming unobstructed from the west, where the prevailing winds bring weather.
On the other hand, if morning skies are reddish, it’s likely that moisture-laden clouds are reflecting light from the sunrise in the east. (Brooklin, Maine)
