With your past experience of forecasting do you think there is a difference in chances for turbulence with red eyes from Las Vegas to the east coast? In my mind I would think less mountain air turbulence, but no difference otherwise. Just curious on your opinion.
I do think, generally speaking, the best times to fly are super early morning (perhaps the best), with red eyes the second best, all because the air is colder and less excited from the night time. The sun is really the cause of all our turbulence issues, but also supports life too. May not help too much with mountain air though, unfortunately.
