Satellite Image of the Week 2019 #41

This week’s image was taken a few mornings ago.

The image above shows the snow over Montana and the Dakotas. Notice that there are two layers of “white”, one being the snow on the ground and the other is clouds over the Dakotas. The satellite loop actually shows some of the snow disappearing from the surface in Montana, as the high pressure and sunny skies sublimate the snow away.

These types of images can be difficult to interpret. Sometimes, there is snow fog from the sublimating snow, and it can look like clouds. Snow fog mixes out quicker, and is more transparent than thicker clouds. Snow fog can indicate still conditions, as wind tends to move the fog along and mix it out quicker.

Thank you for reading this post!
