Just take a moment to consider the feedback loops: huge cloud cover blocks sunlight, so the ground temperature is cooler, so ground air pressure is lower, which probably acts like a sponge to pull in any nearby clouds, which would then increase chances of precipitation. I would imagine the time of day matters too, because cloud cover at night can trap in radiant heat... fucking insane.

I wonder if they put an open bounty on the problem, say for specific geographical regions: find a better prediction scheme for city X, win $Y
