Airline staff do not always have all the information when they tell you the reason for a flight's delay or cancellation. In the absence of details, they may blame it on "weather," since this is a situation the airline can't control and for which it therefore usually isn't liable. But, if you suspect other causes for the delay or cancellation, you may be able to use ExpertFlyer to get the real reason.
And the real reason can make a significant difference. For example, the American Airlines customer service plan states:
"If the delay or cancellation is caused by events beyond our control (like weather), you are responsible for your own overnight accommodations, meals and incidental expenses."
