The August 2009 issue of SmartMoney Magazine featured an article called "10 Things Your Weather Forecaster Won't Tell You". 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.”
