A few days of tropical moistureâ€”remnants of Tropical Depression Noraâ€”brought widespread rainfall to much of northern Arizona. As the moisture was replaced by drier air in the middle- and upper-levels but was unchanged in the near-surface layer, we were left with a situation in which fog might form in the early morning hours.
So, up before dawn to drive out to Mormon Lake and the surrounding basin. And there was fogâ€”at least in one corner of the basin. Here is a 30-minute time lapse compressed down to 17 seconds showing the movement of the fog as it sloshes back and forth.
As this was taking place, the sun rose through a shallow layer of fog.
Bonus: on the previous evening the sun was setting through layers of smoke from the western wildfires.
