Here's when the 'bomb cyclone' will hit, how cold it will be, and how much snow will fall on the East Coast

A cold-weather 'bomb cyclone' is bearing down on the East Coast, bringing up to a foot of snow and bone-chilling temperatures across the region.

The storm is currently sitting off the coast of Florida and Georgia, and will work its way up the East Coast on Wednesday night and Thursday. New York City and Philadelphia are under a winter weather advisory starting at 1 a.m. on Thursday, while Boston is under a blizzard warning starting at the same time.

While snowfall is expected to grind traffic and air travel to a halt on Thursday, the bigger problem is the freezing temperatures set to descend on the region in the storm's wake. The circulation associated with the massive storm will drag frigid air sitting over Canada's Arctic south, plunging temperatures across the Northeast to below zero Farenheit.
