Here it comes: A winter storm that might turn into a genuine blizzard began slamming the Northeast this evening, with 2,000 flights canceled as of 6pm Eastern, reports CNN. Chicago's O'Hare has the most cancellations (650), but airports in Cleveland, New Jersey, and New York were catching up. New York City is still on track to get about 9 inches of snow tonight, but it's the wind and low temperatures that might sting the most. The AP notes that the wind chill there tomorrow could be 15-below zero. In Boston, it might be worse on all fronts.
