I'm just glad there's an new context to discuss it- it's not as nuts as it used to be. I always tried to be logical about it as I observed the effects, and knowing the weather, I noticed lots of times when the 'rain clouds' that used to precede the frontal systems were not producing the rain that should have come with it. I also noticed the 'persistent contrails' that would accompany those telltale rain clouds, and saw the pattern after a while.

"Patterns" i think is the important word here.
