According to the “mets” in the know (and “mets” is a familiar term not for a New York baseball team, but for meteorologists) just about this time, give or take a few days, we are in for a winter weather pattern shift over the northeastern two thirds of the United States.
The North Atlantic Oscillation (NAO for short) is about to go “negative” on us and that can lead to a much colder pattern of air taking hold, particularly in a La Nina year. So hello and welcome Polar Vortex! Brrr!
A few other things are leading the mets to this conclusion that winter weather will be arriving–and possibly a snowy pattern, or at least a stormy patterns–along with it. I will spare you the technical details.
So of course what did I do around the end of November when I started hearing all this talk of negative NAOs? I consulted my squirrels!
For those of you not familiar with the long accustomed practice of consulting squirrels’ nests as a way of predicting winter weather, it goes like this: the higher up in a tree the squirrel’s nest is, the colder (and presumably snowier, but I am not sure they actually predict precipitation–just cold!) the winter will be.
I usually try to find a squirrel’s nest right on my own property. I knew that I must have one in an oak off the edge of my property because every morning and evening my dog loses her mind barking when she sees the squirrels running up and down the tree trunk. So I started looking up into the tree.
Oaks are funny because they hold a lot of their leaves, even into the winter, so it’s sometimes tough to see into the canopy.
Finally I spotted the nest, almost at the top of the tree. (But you can tell just from this photo how difficult that was. It’s about mid-photo, way up high, right where there’s an awkward looking crooked branch. )
So I guess the mets are right. It’s Polar Vortex time. Better break out the woolies. I’m already wearing the long underwear. Not sure how much more I can pile on!
