The polar vortex is breaking down unusually early in the season, a process that follows a sudden stratospheric warming event forming since late October. The breakdown is expected to send a burst of cold Arctic air into the United States around Thanksgiving, temporarily clashing with the warmer conditions usually associated with the strengthening El Niño this winter. AccuWeather long-range forecaster Paul Pastelok called the situation unprecedented for November. Experts say how the two patterns will affect local weather remains to be seen.
