Polar Vortex 2024 March. At least not this time around. With a stratospheric warming event expected to develop, we currently see a rapid breakdown of the polar vortex and a cold weather pattern change across the united states in the second half of february.

Based on the january 15, 2024 forecast, the stratospheric polar vortex winds will decrease to zero, just reaching the threshold of a major sudden stratospheric warming, in the next day or two. As we’ve mentioned a few times before in this blog, the stratospheric polar vortex has been pretty active this winter.
