With the possible exception of Phil Connors

I’d hate to be a weather forecaster. You do an excellent job of understanding weather systems that are inherently unpredictable (chaotic, in fact) using physics that isn’t always very well understood, yet everybody thinks you’re rubbish because the view out of their window isn’t what you said.

Having said that, there are times when the whole thing is a foregone conclusion. The rules should be rewritten: chaotic, but cloudy during eclipses.
