Okay, this is like a sore tooth. Somebody's wrong, and I don't know if it's me. A queazy feeling.

Listen to this though:

The prize for the single most inconsistent forecast goes to Channel 5’s Devon Lucie who on Sunday, September 30th predicted a high temperature of 53 degrees for October 7th, and seven days later changed it to 84 degrees — a difference of 31 degrees! It turned out to be 81 that day.

A close second was Channel 4’s Mike Thompson’s initial prediction of 83 for October 15th, which he changed to 53 just two days later. It turned out to be 64 on the 15th.

Uhhh.... it's remarkable that a forecast changed significantly in SEVEN DAYS? What?!

The weather is the canonical example of mathematical chaos in an (in principle) deterministic system. Of course the forecasts will change, because Tuesday's weather sets the initial conditions for Wednesday, and chaotic systems are ultra-sensitive to initial conditions! The forecasters would be idiots if they didn't update their forecasts as much as possible.

The "close second," moreover, should be first! That change occurred in a two day period versus a seven! ARGGHHH.
