Question
Spun Cloud
Spun Cloud  
I took a picture of a cloud today. It looks like spun cloud is the easiest way I can explain it. The cloud didn't appear to be spinning and and it was in view for at least 40 minutes. I took the picture on I83 in between Harrisburg and York PA.
around 715 this morning (10/5/15). What kind of weather would create this kind of cloud?
Thank you D

Hi Don

At first glance it looks like it's cirrus clouds above an anvil cloud:

It seems like it was cirrus clouds only that were being influenced by high winds in the jet stream.

So, for more info on the jetstream, see:

And for examples of cirrus:

Typically jet streams are associated with fast moving weather changes.
