The National Weather Service warns that between eight and 13 inches of snow will likely fall late this evening and early tomorrow morning in New York and Connecticut. The agency issued a winter storm warning, urging residents to travel only in an emergency in the time between midnight tonight and 6 a.m. Thursday morning. (No word yet on whether that travel warning applies to walking up Science Hill for Wednesday classes.)

This morning, Mayor John DeStefano Jr. issued an on-street parking ban for all downtown New Haven streets, as well as all major thoroughfares throughout the city, to begin at 5 p.m. Wednesday.
