Interesting, tomorrow you have a 0% chance of precipitation, so let's see what happens. Do other people notice this? Could you snag some pictures of
the planes/contrails for us to look at? Its an interesting concept, but I think we need to start doing what we can to figure out exactly how real this
is, ie. examining the pictures to see if there's a difference in the formation and density of these trails, opposed to ones coming from normal air
traffic and identifying the planes. If you have the opportunity, a pair of decent binoculars wouldn't be a bad idea to have along either so you could
possibly get a better look for any characteristics that would better lead to the plane's identification.
Good luck with your prediction, but honestly, I'm hoping you're wrong. Only because if this could be officially disproven, it could be one thing
less I have to be paranoid about!
