Low clouds and fog

Back in San Francisco, nearly every weather forecast was the same: patchy morning low clouds and fog, clearing to the coast by mid-day. Day after day. Actual rain was a big news event, even more so in times of drought. We don't have that problem here. But, like clockwork, the November fog is upon us.

Fog forms in the vineyard at sunrise. On this day, it didn't get very thick and it burned off quickly.

It's not at all like San Francisco fog in that it's not borne in by wind. The air is still when the fog forms at sunrise, often after a crystal clear night. High pressure keeps it tacked to the ground for most, if not all, of the day.
