I watched flight radar off and on this afternoon and saw flights all over the place, some were in the mid 30k ft range as they were overflying to farther destinations. I also have a nice camera pointed at the sky. Zero trails were visible today.
Now looking at the 250 mb map currently it looks pretty damn cold up there to me. -40-55 seems to be the typical temperatures at that altitude. So I still don't understand. Why zero trails, not a single one formed?

If the troposphere is extremely dry they dissipate almost immediately. I didn’t fly today so I don’t have a briefing to look at, but that’s my guess.
