New York City knows the drill by now, but that doesn’t make a wet and cold Monday any less sad. The latest wintry mix of the season will drop four to eight inches of snow on New York City through this afternoon, and then maybe some more tomorrow. Schools are open (but field trips are canceled), alternate side parking is suspended, and the Upper East Side is doomed to be like the North Pole, but more neglected. Any Super Bowl tourists hoping to get home are probably stuck here forever. Welcome to our endless winter.
