How do you know it doesn't wash if you even have to ask that question? I'm not a weather "expert", but I have studied it enough to understand the theory of how such things are claimed to work, and I mean.. Just watch some radar or satellite imagery sometime, things really do vary a lot from one spot to the next.

There's just so much information lacking from your evidence that I'm not sure much can be said, we don't know how cold it was at those temperatures or in various areas and so on so forth. Maybe they are chemtrails, maybe they aren't. I don't know for sure. I'm open minded to both perspectives on the subject.

In regard to ice crystal not creating weather, not by themselves... However, I have seen contrails/chemtrails mix with the local weather and do similar and there is actual scientific literature suggesting that "contrails"/"water vapor" do indeed interact with weather and create clouds and even precipitation. So, I would suggest perhaps you study the subject a bit more as there are explanations where you claim there are none and regardless of who is ultimately correct it does seem like you don't quite have the expertise in weather and how it works to make some of the claims you are making, at least that is how it appears to me.

And yeah, I'm not sure about your last statement... People see stuff for themselves all the time that is wrong because they perceive it wrong. The mind plays tricks as well and I'm not sure I agree there, however I do appreciate you sharing your thoughts and perspective and I respect what you believe even if I'm not quite there myself. Peace.
