At What Temp Do Contrails Form?

Hi all,
I was noticing the other day all the contrails in the sky over my house. I live in York Pa, about 90 miles northwest of PHL, and about 150 miles southwest of EWR. I am also within 200 miles of BWI, JFK, IAD, and DCA, so I tend to see lots on contrails. York Pa is major fly over country!
Usually in the morning, on my way to work, the sky is totally streaked with contrails during the westbound morning rush. Made me wonder about when contrails form.
About what tempature do they form? Also, if I look at some of them, I can see what seems to be maybe 20 miles long, and some start and stop. Is that cause by a warm updraft? I dry patch of air?

Thanks in advance!

Russ


My glass is neither 1/2 empty nor 1/2 full, rather, the glass itself is twice as big as it should be.
