A major and potentially historic snowstorm will hit New England as a blizzard Friday and Friday night, with the height of the storm occurring late Friday into Friday night..

The merging of two storms, an Alberta Clipper from the west and a storm from the south, will bring tremendous snow and damaging winds to many locations throughout the Northeast.

A widespread swath of 12-24 inches of snow will stretch from southern New England to coastal Maine. Some towns and communities in this area may pick up over 2 feet of snow.
