Most hunter/gatherers (i.e., guys) have an innate interest in the weather. I read somewhere that the Weather Channel is one of the most popular TV channels among men. Observing animal behavior is a great way to forecast pending weather without a TV. I'm a big fan of Tom Skilling (WGN-TV Meteorologist) because he doesn't just tell you the weather, he teaches it.
In the Chicago area the geese are the best forecaster of cold weather to come. During this past week Tom has been pointing out this expanding dome of cold air emanating from the arctic and working its way southward. We've had a very mild winter so far and bird migration has not been very obvious. But this week I've seen multiple flocks of geese on a daily basis flying south out of Canada.
The Northeastern US will experience its first true cold snap of the winter this upcoming week.
Thank you, geese.
