Lone Peak Cap Cloud

Sunday was a beautiful day and we were treated with the appearance of one of my favorite Wasatch weather features, what I call the Lone Peak cap cloud (other examples here, here, and here).

This is typically a shallow cumulus or lenticular cloud that covers Lone Peak and the Little Cottonwood–American Fork divide during periods of moist, strong southerly or southwesterly flow.  Sunday's display was particularly cool because some snow was somehow able to form in the shallow clouds.  You can see it falling out in the image above just north of Lone Peak.
