Research Scientist Judah Cohen speaks with Boston Globe reporter Ken Mahan about how a disrupted polar vortex (PV) could impact weather in the United States in the coming weeks. “The PV has been doing its best Mr. Fantastic impression, stretching and compressing continuously,” allowing frigid air to escape southward, Cohen explains. “If we (New England) do receive colder weather, but not quite the cold we experienced in late January, again from this larger PV disruption, it will be either late February and early March.”
