Washington Post: “Fierce ‘bomb cyclone’ to disrupt holiday travel, unleash Arctic outbreak. The storm could bring blizzard conditions, ‘life-threatening’ cold, extreme wind chills and travel headaches for large parts of the Lower 48 states. A massive storm system is set to snarl holiday travel and bring an onslaught of wintry weather to millions across the Plains, Great Lakes, Ohio Valley, Northeast and even interior Mid-Atlantic. The developing cyclone will deliver heavy snow and blizzard conditions to some and downpours to others between Wednesday and Friday night, all coming at a time of year when more than 110 million Americans are expected to take to the roads and air. The potential exists for serious travel disruptions at major airport hubs in the Midwest and Great Lakes, including Chicago’s O’Hare International, where heavy snow and howling winds are expected — with the worst conditions late Thursday into Friday. The combination of snow and wind will bring visibility down to near zero at times. Travel could “become extremely dangerous and life-threatening, particularly in light of the bitterly cold temperatures during the height of the storm,” wrote the National Weather Service office serving Chicago.
Nearly 50 million Americans are under winter storm warnings, watches and advisories, and a number of them could find themselves blanketed by blizzard warnings before long. The anticipated storm system will explosively strengthen, at a rate sufficient to qualify it as a “bomb cyclone” — which is the most intense breed of mid-latitude storms…The Weather Service office serving Buffalo is calling it a “once in a generation” storm system. [‘Once in a generation weather events’ have been superseded by continuous weather calamities.]
