~Winter may be officially over, but it said final goodbye in NE USA on March 28
~It was a Rogue Vortice, very cold Cold Temperature North Pole cut off from the Polar Vortex
~Expect more of these more often for many winters to come
The geometry of winter has changed, it has become thinner, not bloated by darkness as it use to be. In effect, winter still rages but for smaller areas, when so
the vastly larger stable warmer air deepens the Cold Temperature North Pole(s), not often at the North Pole, but wherever it may be. Sometimes very surprisingly, like a few days ago as on March 28 over Michigan USA, suffering again a cold blitz, something special makes it there, perhaps it’s the location tip of the elongated end of the Polar Vortex, stretched out with favorable cooling weather twinned with some cold air advection. At any rate, being in late March, such a low latitude CTNP has no chance of living long, as it did so.
However the geometry is of interest:
