Hi Glenn,
         Terry and I are saying the same thing, although he has managed
to be a little more clear.
 At temperatures above freezing the only variable is atmosperic pressure
or altitude,once fog is in evidence you have passed 100% RH and the
water has changed from vapour into droplets.Hence the term dew point.
The ice crystals at low temperatures is usually caused by the mixing of
warmer air with cold, it sure looks pretty in this part of the world.
In this part of the world at -40 breath out and you can create your own
mini snow storm sneeze and its a blizzard.
