Heavy Snowfall and Extremely Cold Temperatures from the Midwest to the East Coast

Two low pressure systems converged over the Mid-Atlantic Region Thursday resulting in heavy snowfall potential and dangerously cold temperatures from the Midwest through the central Appalachians and into New England into Friday.
Heaviest amounts of snow, upwards of 10-12 inches, are expected for coastal southern New England, and along the Great Lakes. Some areas of coastal Massachusetts could see 12-15 inches of snowfall. In addition to heavy snowfall, north to northeast winds gusting to 35 to 50 mph could cause blizzard conditions for eastern Long Island and coastal Massachusetts. Wind chill temperatures well below 0 F are forecast for much of the Central and Eastern U.S. on Friday.

Wind chills below -30 F are expected for portions of northern New England. This image from the GOES-13 satellite on January 2, 2014 (17:45 UTC) shows the two weather systems (moist air from the Gulf of Mexico and cold air from Canada) moving across the U.S.
