At least 11 traffic deaths were blamed on slippery roads.
Snow accumulations of up to 15 inches were reported in parts of southern and western New York, including a record 14.3 at Buffalo, and 10 inches piled up in northeastern Ohio. Boston had 7 inches by early Wednesday and parts of Connecticut measured more than 9.
"I'm tired of this," Peg Woods said in Newton, N.J. "I just put my snow shovel away the other day."
Many New Hampshire schools closed or delayed classes Wednesday and some Connecticut schools also delayed their openings. Hundreds of Ohio schools canceled classes Tuesday, and several districts closed early Tuesday in New Jersey, New York and Connecticut as roads became wet and slippery.
"This will be winter's last hurrah, so we might as well enjoy it," Tom Kearns, 53, said as wind blew the flakes through downtown Boston.
But co-worker Eric Argenault, 32, said the snow meant one thing: "I've gotta fire up the snow blower and go to town."
Flights at New Jersey's Newark Liberty International Airport were delayed by up to 90 minutes Tuesday, and more than 100 flights were canceled. Travelers were urged to call their carriers as a precaution Wednesday.
Planes were also canceled or delayed by up to 90 minutes Tuesday night at Boston's Logan International Airport.
Wet roads were blamed for numerous highway crashes Tuesday, including accidents that killed seven people in Pennsylvania, three in New York and one in Ohio. Police in Ohio also were investigating whether snow contributed to a crash that killed two other people near Akron.
