This should cause Peconic Jeff to bug out. Wave clouds...hell yeah! Spotted on Facebook in a post by Ely, this image was taken in Alabama a day or two ago. From the Cloud Appreciation Society: "The breaking waveforms of Kelvin-Helmholtz clouds are the result of shearing winds up at cloud level. 
A particular type of turbulence can develop in a layer of cirrus cloud, which happens to form below an inversion ...between air currents of differing speeds and/or directions. Sea waves break as their bases are slowed down upon reaching shallow water and their crests surge ahead. Cloud waves break in the same way: when their crests are pushed ahead of their troughs by the difference in air currents"

Cool pic. Hoping to wave sail some Kelvin-Helmholtz waves tomorrow morning (& SUP on Fri/Sat).

I love the one cloud that looks like a horse.
