Week’s second storm milder for some

NEW YORK — Snow from a mild but widespread winter storm began falling Saturday over most of the Northeast and the upper Ohio River Valley, the second in less than a week for the regions.

Forecasters expected the heaviest snowfall of up to 8 inches in southern New England, including Boston and Providence, R.I., by late Saturday. Farther south, New York City and Philadelphia saw a mix of rain and snowfall as the storm moved in from the west. A few inches of snow were forecast.

“Expect those accumulations to kind of work their way northeastward through much of New York state and much of New England,” said meteorologist Brian Hurley of the National Weather Service.

About 20 vehicles piled up in a storm-related chain-reaction crash on Interstate 93 in New Hampton, N.H., police said, and five people were injured.

Drivers throughout the regions were warned to be cautious. Officials lowered the speed limit to 45 mph on much of the Pennsylvania Turnpike, about 300 miles from the Ohio state line to east-central Pennsylvania.

Flights at Philadelphia’s airport were delayed about an hour, mostly arrivals, spokeswoman Stacy Jackson said.

Parts of southern Indiana saw 6-8 inches from the storm, some in areas that had received more than a foot from a blizzard earlier in the week.

That blizzard was part of a storm system that dumped more than a foot of snow in some places and has been blamed for at least 16 deaths. It also spawned more than a dozen tornadoes in Alabama, the National Weather Service said.

But Saturday’s snow “shouldn’t be as heavy with the previous storm,” weather service meteorologist Marty Rausch said.
