The National Weather Service warned that “very strong winds” were expected Sunday night in the Philadelphia metro area and southern New Jersey.The high winds led to widespread power outages across much of the Mid-Atlantic on Sunday, according to Poweroutage.us, which tracks power outages in real-time.In the Allegheny Mountains, which straddle Virginia and West Virginia and extend into Maryland and Pennsylvania, a blizzard warning is in effect from 1 p.m. Sunday until 3 p.m. Monday.Across many parts of the Northeast, the snow was set to turn into sleet and freezing rain through Sunday night, with ice accumulations of up to a quarter inch, according to the Weather Prediction Center said.On Sunday, Washington could record up to a half inch of rain, to go along with thunderstorms, heavy rain and winds up to 60 m.p.h.“We’re going to see a pretty big temperature swing too, with temperatures going from the mid-60s down into the 30s by the overnight hours,” Mr. Belak said.About 2.5 inches of snow fell on Saturday evening in parts of Connecticut, including Fairfield and Middlesex Counties. Areas across Massachusetts and Rhode Island got two to five inches of snow by Sunday morning and as much as seven inches fell in northern Massachusetts.An unusual surge of warm, springlike moisture poured into the Ohio and Tennessee Valleys and the lower Mississippi Valley on Saturday — triggering torrential rains that turned roads into rivers and created a sloppy, wet mess.Some of the most severe flooding occurred in northwest Tennessee and in western and central Kentucky. At least nine people have died in the storms, one in Georgia and eight in Kentucky, officials said.By Monday morning, the storm is expected to be centered over Maine and southeast Canada before drifting northeast into the Atlantic Ocean.This storm is dragging a mass of bitter cold Arctic air from Canada into the Great Plains and will pull it into the south-central United States. Some locations will likely record their lowest temperatures of the winter so far, the Weather Prediction Center said.The cold will set the stage for the next winter storm, which is expected to hit the Central Plains on Monday night, the Mid-Atlantic by Wednesday and the Northeast by Thursday, although details were still uncertain.Johnny Diaz, Nazaneen Ghaffar and Alexandra E.
