May I comment about contrails? I grew up on a farm. My grandfather and
father passed on what they knew about farming when I was growing up. One
of the things was an observation about contrails and weather. When you
see a short contrail that disappears quickly, the high altitude air is
dry. Don't expect rain anytime soon. When the contrail is long, lasts a
long time and spreads out, it is a sign of a lot of high altitude
moisture. Expect rain in a day or two.
