The Year the Arctic Shifted South
(Originally published on Washington Post's Capital Weather Gang blog)
Last week, Chicagoans were treated to one of that city's worst blizzards of all time. Featuring several rounds of thundersnow — a relatively rare phenomena that has been in abundant supply this winter, making appearances in D.C., New York, Boston, and now Chicago

Yet for a key region of the globe, it's actually proving to be a remarkably warm winter so far, which, believe it or not, may help explain why it's been so cold and snowy in the U.S.
