A large area of low pressure moving north from the Gulf of Mexico on February 5th combined with low pressure across the Ohio Valley and intensified over the Mid-Atlantic states. This produced an historic snow storm across western Pennsylvania, northern West Virginia, Garrett county Maryland, and eastern Ohio from the afternoon of February 5th to the afternoon of February 6th. Over 2 feet of snow fell across portions of Garrett county Maryland, and in Preston and Tucker counties in West Virginia, with locally 3 feet in some locations. Storm totals ranged from 37 inches in Friendsville, MD to 22 inches in Terra Alta, WV. Across Pennsylvania, 18 to 24 inches of snow fell roughly between an area from SR 422 and I-70, with 21.1 inches of snow falling in Pittsburgh. This was the 4th largest snowfall on record in Pittsburgh. Over 2 feet of snow fell in the ridges of Westmoreland and Fayette counties in Pennsylvania. Along and north of I-80 in Pennsylvania 6 to 18 inches of snow fell. South of I-70 in Pennsylvania, eastern Ohio and northern West Virginia amounts ranged from 10 to 20 inches. North of I-70, in eastern Ohio, snow accumulated 12 to 18 inches. The snow was wet and heavy in Pittsburgh and areas south, bringing down trees and power lines with around 200,000 people without power at some point after the storm. Roads were not passable for 2 to 3 days in some locations, and power was not restored to some homes until 3 days after the storm.
