To set the record straight, I am and have been a professional meteorologist for 34 years and operate the WeatherLab at Panama City (Florida) where we study such as that on a daily basis. It is you who have been fed a load of almost-fact.

Contrails form at a level where the dewpoint is below the freezing point of water. The dewpoint at upper levels of the atmosphere is cheked twice daily by weather balloons launched from NWS sites and is displayed on a plot known as a SKEW-T.

We study this day-in and day-out and you come along with something you have picked up somewhere that flies in the face of the actual facts.

Tips my hat to prognosticator guy.

Now I'll sit back and watch the Capt and J H discuss this.
