Mammatus Clouds in South Dakota – Mary Kalbert photo

In the SJ Update Mailbag today, we have a photo from Mary Kalbert who was recently visiting friends in Spearfish, South Dakota when they saw these clouds from the upstairs balcony. How does this relate to Friday Harbor? Well, here it is in Mary’s words…

The connection, I think is how different our mild and generally stable weather showcases types of clouds and formations that are drastically different from clouds (mammatus and others) in the Midwest that are associated with extreme layers of instability in the atmosphere. This can result in violent and spectacular thunderstorms.

Yeah, I think I’ll stick with Friday Harbor’s weather. Thanks for sharing, Mary!
