Which is actually a line forma Jethro Tull song, but sums up this picture pretty well, down river the sky was clear and the setting sun was shining under the dark gather cloud to the north. The wind was howling and kicking up small standing waves in the river.
Fortunately it passed to the north, but was quite a squally.
The Lines form heavy Horses - Jethro Tull
Bring me a wheel of oaken woods
A rein of polished leather
A Heavy Horse and a tumbling sky
Brewing heavy weather
