Nearly a million New York City schoolkids are expected to be back in class today — and they had better bundle up.
At least three dozen schools likely won’t have heat as temperatures hover just above freezing in the morning, Mayor Bloomberg warned yesterday.
“Please dress your children with that in mind,’’ the mayor said. “If the schools were dangerously cold, we obviously wouldn’t open them. But if they’re chilly, extra sweaters for the kids is something that should make some sense.”
