Weather Tidbits: Altocumulus
The main headline on this Weather Tidbits is about the 2nd mid-level cloud which is the altocumulus. This cloud type is normally puffy and gray, that usually increases as a frontal system nears the area. It’s a concern for aircraft, as ice can build up when it merges with the other mid-level cloud altostratus. The main variations are undulatus which occurs with an altostratus, a mackerel sky that indicates a nearing cold front and castellanus that indicates a thunderstorm later in the day.
