Low pressure formed along a stalled front just south of Pennsylvania and slid off the Mid-Atlantic coast before rapidly developing and pushing northeastward off the New England Coast. This storm produced a wide swath of 6-10 inches of snow from the Laurel Highlands east-northeastward across the Ridge and Valley region and into the Poconos. This snowfall occurred less than 24 hours after many of these same locations saw temperatures well into the 50s. Snowfall rates of 1-2 inches per hour were common at the height of the storm, and there were even reports of thunder-snow.
