Shelf Cloud pictures shared by readers


View at EarthSky Community Photos. | Glenn Hughson in Lawrence, Kansas, captured this picture of a shelf cloud on August 31, 2021. He wrote: “I went to let the dog out yesterday morning, when I noticed this shelf cloud quickly approaching. There were several trees and houses blocking my view, so I grabbed my drone and sent it up in the air to get a better look. This thing looked … intimidating … from this view a few hundred feet above my house. It was coming in fast, though, and I didn’t want to lose the drone in the storm. So I snapped a few photos and then quickly landed before the gust front hit. Despite its somewhat scary appearance, this was not a severe storm. It just rained sideways for about 15 minutes before moving on.” Wow. Thank you, Glenn!

Shelf clouds, also referred to as arcus clouds, happen at the vanguard of thunderstorms. They announce the arrival of storms and, when mixed with cumulonimbus thunderheads, can seem like big alien motherships. Shelf clouds kind when the cooler air of a thunderstorm encounters heat, humid air and lifts it. As the shelf cloud passes over you, you’ll discover a drop in temperature, and winds choose up because the gust entrance strikes by means of. Rain follows quickly behind.
