There were a few notable signs that seem to hold true in both hemispheres and particularly closer to the poles. The Northern Lights were thought to be a sure sign of windy snow storms in the offing and the Southern Lights are also considered a storm warning. This is probably a fairly accurate assessment as the clear, crisp winter days that allow viewing of the Borealis are often followed quickly by clouds and storm.
Another sure sign of storm from late fall to early spring is the bunching up of large, domestic animals at pasture. Horses and cows were turned out almost daily, regardless of weather, and seeing them stand together with their breath making foggy clouds around them was often an indication that it was time to bring them back to the barn. Native Americans on the
Great Plains had a similar weather indicator but in their case, the animals were bison.
A final winter storm warning was said to be falling stars or, in particular, meteor showers. This probably speaks to the same sort of weather patterns as the beliefs about the Borealis. If the sky is clear enough to see falling stars, it naturally follows that sooner or later it will cloud up again.
