Weird sky/cloud formations

Early Sunday evening, I noticed some weird cloud formations -- or, perhaps, jet streams? -- in the west/southwestern sky while I was outdoors and happened to have my PowerShot G12 with me, so I took some pictures. Turns out ... I had a short window of opportunity to lock in on a color shade, as the setting sun and/or its reflected rays transformed the color of these formations from the usual bright white to a bronze tint in a span of 10 minutes or so during the time I was observing and photographing.

There probably is a perfectly good explanation for these helter-skelter patters, and they probably are jet streams (shows you how scientific I am to not be able to recognize the difference). But of these streaks looked too wide and splayed for jet streams, and yet ... too narrow and too tubular for clouds. Perhaps it was a confluence of clouds and jet streams. 

I did a quick hunt online, and not surprisingly found that weird cloud formations are not usual, but in the pictures of examples of "weird cloud formations," I didn't see any examples that resembled these helter-skelterlike skyscapes!

The image at the top is a broad overview of the spectacle; the one immediately below is a somewhat tighter look at the same composition. Both were taken before the aforementioned bronzing effect, the first of which you can see in the portrait orientation two shots below.




Above and the next two below: After the sunset/bronzing effect took hold. That tiny black figure to the right of the formation on the left is a passing aircraft. A crop of the above frame to bring out better detail of the aircraft appears below.
 
 



Above: This is not entirely a sunset bronzing effect; while I did capture this after the sunset started tinkering with the cloud colors, it's also the result of a PowerShot G12 in-camera melding of three images captured in rapid succession (also known as high-dynamic range, or HDR).
