Original Note:
These are altocumulus undulatus clouds. They have a wavy appearance due to wind shear. Occasionally, they form two or more overlapping waveforms. The presence of Altocumulus undulatus may indicate precipitation within the next 20 hours, or simply a cloudy day. https://clouds.fandom.com/wiki/Altocumulus_undulatus https://earthsky.org/earth/undulatus-clouds-wavy-rows/ https://www.youtube.com/watch?v=FTXNWxqPXzA&ab_channel=MelStrong
