Ice in N.Y. Forecast for Christmas as Strong Storm Sweeps South

A weak winter storm may coat roads west and north of New York City with a layer of ice by Christmas morning and leave an inch of snow in higher elevations.

A much more powerful system will sweep across the southern and central U.S. tomorrow with severe thunderstorms and the potential for isolated tornadoes from eastern Texas to the Florida Panhandle, said Rob Carolan, founder of Hometown Forecast Services in Nashua, New Hampshire.

The eastern storm, currently bringing rain to Virginia, will move south of New York City overnight, Carolan said. Ice will probably coat roads from Newark, New Jersey, to New York and into southern Massachusetts along the Interstate 95 corridor. In New York City, the storm will bring rain.

“It doesn’t look to be a big deal; it looks to be more of a nuisance,” Carolan said by telephone.

A winter weather advisory warning of ice and as much as 1 inch (2.5 centimeters) of snow stretches from eastern Pennsylvania to southeastern Massachusetts, according to the National Weather Service.

In Pennsylvania, New Jersey and New York the advisory is in place from 7 p.m. until 7 a.m. tomorrow. In New England, the warning is in effect from 10 p.m. to 10 a.m.

The more powerful system may leave 6 to 8 inches of snow across Oklahoma and Arkansas, and as much as 15 inches from Missouri to southern Illinois, according to the weather service. Snow is also forecast for parts of Kentucky, Indiana and Ohio.

Winter storm warnings and advisories for that storm stretch from Oklahoma to western Ohio. The snow across Oklahoma, which will start overnight, will be accompanied by 20- to 30-mile-per- hour winds with gusts as high as 45 mph (72 kilometers per hour).

The system will bring rain and sleet to the New York City area later this week.
