The Famer's Almanac is almost always accurate about what the weather will be at a certain time of the year- How does it do that???

Seems to me that your selective memory is at work - recalling the times it was accurate and forgetting about those it wasn't. Some skill above climatology *may* be shown for the general seasonal trends, but it is certainly impossible to predict weather for specific days a year in advance. The way to test them of course is with verifications. For example, choose a region and use the observed data in it for each month to see how accurate their forecast temperature anomalies are. Do the same thing qualitatively for the daily forecasts (have to develop some accuracy criteria - e.g., if the forecast says cloudy & cool for a 4 day period, what type of weather would be considered accurate). Compare the latter with the zone forecasts from the National Weather Service. That takes quite a bit of effort if done properly, but sure beats an opinion based on a general notion.

It is not completely accurate. The Farmer's Almanac studies weather trends for the past several year and predicts the weather based on these trends.

I don't know about the weather where you live but the almanac was way off predicting weather around hear this past winter. I've observed that it is usually right about half the time. That's the same as flipping a coin. You always hear about it's correct guesses but never about it's failures.......
Until now.

It doesn't. No more than planetary alignment predicts life events.
Anyone can say "In the last two weeks of December 2006, a massive costal storm will sweep through the Northeastern United States" - - or some crap similar to that.
These things happen, we expect them to happen. In fact I'll stick to the prediction I just made. If I'm right, it doesn't mean that I can forecast the weather six months in advance...it just means I might not be a complete retard.
