A forecast warns of extraordinary winter weather across the U.S., Europe, and Asia due to a rare weather event involving stratospheric warming and the polar vortex. As temperatures are expected to plunge, the potential for extended cold and significant snowfall could increase before Christmas. The polar vortex is reportedly wobbling, which may bring Arctic air to regions like New York and unsettled conditions across the Midwest. This phenomenon is likely to affect energy prices, with utilities anticipating higher winter bills. Travelers should prepare for potential disruptions caused by the anticipated cold snap and heavy snow.
