Polar Vortex Blog

A blog about monitoring and forecasting the stratospheric polar vortexes and how they do and don’t—mostly don’t!*—affect extreme winter weather and seasonal climate. *Seriously, we’ll probably spend a lot of time explaining how the latest wintry weather blast bearing down on us from Canada probably has nothing to do with the polar vortex.
