Why planes leave white trails in the sky - and how you can use them to predict the weather

This is the same phenomenon we see when we breathe hot air on a cold day. Long contrails form in humid conditions while short contrails form in low humidity. Long contrails are a sign a storm may be coming. Short contrails are a sign fair weather is coming.
