(Trends Wide) — A major winter storm battering much of the central and eastern United States is causing record-breaking temperature drops and harsh snow conditions that have resulted in flight cancellations, highway closures and several state emergency declarations.
The storm is affecting nearly every state, with more than 100 million people in the country currently under winter weather and wind chill watches, in what the National Weather Service calls a “once-in-a-generation event.”
