6 a .m. – 6 p.m. Monday: The brunt of the storm blossoms north and in NYC, and however far the storm pushes north will get into heavier snow. Winds will be gusting 40-45 mph in NYC to 50+ mph along the coasts. Coastal issues could arise.

Snow could fall at heavy rates of 1″ to 2″ per hour at times, leading to near whiteout conditions.

6 p.m. Monday – 6 a.m. Tuesday: Storm brunt is Monday afternoon, but it could linger into early Tuesday morning with gusty winds and stronger snow bands.

6 a.m. Tuesday: Lingering snow showers taper off through the day.

So how much snow should you expect by the time the storm moves out?

The New York City area could see around 12-18 inches, but there are pockets where 18-24 inches are possible just northwest of New York City.
