US EditionThe polar vortex is about to bring a wild weather pattern change
A rare sudden stratospheric warming event is forecast to peak in late November, likely bringing colder-than-average temperatures to 35 U.S. states through December, NOAA said.
- The stratospheric polar vortex is weakening and warming dramatically, an unusual event for November.
