Fiery Sunset & Kelvin-Helmholtz Waves

I was not planning another update right now but found this sunset moving and wanted to share a few frames, as well as highlight some relatively 
rare wave clouds which formed just before dark.

One could say the Lord certainly blessed whom ever was lucky enough to be standing upon the High Knob Lookout on this fiery evening!

This fiery glow filling the horizon looking toward the low V-notch in the crestlines of the High Knob Massif marking Little Stone Mountain Gap and the Powell Valley Overlook area.  Wow!

Just before fall of darkness these next frames capture a set of relatively rare clouds known as Kelvin-Helmholtz Waves.

 In this case the troughs of the waves are not completely visible, or outlined by condensed vapor, since the air was just a little too dry at that level.

The shear instability responsible for these clouds is not really rare at all; however, it is not common to see Kelvin-Helmholtz clouds without visible troughs every day.

One can imagine how the curl in the top of each wave cloud might connect to the bottom of each adjacent cloud to form a connected set of waves similar to those which roll, or whose energy travels, into a beach upon feeling the frictional drag of the upward sloping bottom.

Another fine illustration of the 
fluid beauty amid which we live.
