The August 2009 issue of SmartMoney Magazine (http://www.smartmoney.com/smartmoney-magazine/?issue=2009-08) featured an article called 10 Things Your Weather Forecaster Won't Tell You" [1]. It was a well-researched article with a number of good points. The ten things are:

• "Long-term forecast? Your guess is as good as ours."
• "We’re pretty accurate—as long as the sun is shining."
• "We’re often more show biz than science."
• "Our high-tech gizmos do everything but predict weather."
• "Want the temperature? Don’t ask the National Weather Service."
• "Weather is big business."
• "Bad weather means big ratings..."
• "...and it’s always bad during sweeps week."
• "Accuracy? Who cares."
• "Weather is recessionproof."

ForecastAdvisor is mentioned prominently. It's a very good article and definitely worth the time to read.
