Very rarely in the USA Northern Mid West, maybe once a year at most, I will see a very smooth, concave cloud floating over the sky that looks exactly like a lenticular cloud, and only a few minutes, it starts to dissipate. What would explain this phenomena?

1$\begingroup$ The en.wikipedia.org/wiki/Lenticular_cloud shows one expired reference to something that suggest that shear winds created by fronts might be the reason. $\endgroup$– CommunistyJun 27, 2017 at 11:50

$\begingroup$ There's definitely a lot of storm fronts in my area throughout the year, I've definitely seen a lot of weird and uniquely shaped clouds, but none as rare as the lenticular. $\endgroup$– RayOfHopeJun 27, 2017 at 18:24

$\begingroup$ Is there a lake in that direction, sometimes lakes can alter the winds around them. $\endgroup$– JohnJun 27, 2017 at 23:46

$\begingroup$ Will develop an answer if I can find time. Mountain waves are anchored to a ridge but can excite a wave that extends hundreds of miles downwind. At the leaks of the wave anywhere along it where the moisture is right you can get clouds like you have seen. $\endgroup$– caseyJun 28, 2017 at 2:41
