winterlike storm from the Midwest will move in this weekend, then handoff to a new coastal storm that strengthens by Monday.

Accumulating snow is forecast to occur in Boston; Hartford, Connecticut; New York City and even to some extent around the Trenton, New Jersey, and Philadelphia area from the storm.

The heaviest snow, on the order of 6-12 inches is forecast from the northeastern corner of Pennsylvania to central Massachusetts and southwestern New Hampshire. However, pockets of 12-18 inches are in store for the Catskills and Berkshires, where an AccuWeather Local StormMax™ of 24 inches is expected.

Heavy snow is in store for much of the Hudson, Mohawk, Connecticut river valleys with a few inches as far south as parts of the Delaware and Lehigh valleys.

Part of the storm will bring ice, rain and a wintry mix along the Interstate-95 corridor from Philadelphia to New York City and Boston, with the ice and mix to occur during Sunday into Sunday night.
