This moist airstream helped to enhance snowfall rates, with 2-4 inches per hour occurring at some locations. Storm total snowfall accumulations<\/strong><\/a> were as high as 36.1″ in Pennsylvania, 35.5″ in New Jersey, 25.6″ in New York, 24.0″ in Massachusetts, and 19.0″ in Connecticut.<\/p>\n

Another feature that played an important role in enhancing\/prolonging heavy snowfall rates was a TROWAL<\/strong><\/a> — appearing as a tongue of higher Equivalent Potential Temperature within the 850-700 hPa layer, just north of the surface occluded front — moving inland and feeding moisture into the southern edge of the cold conveyor belt seen on GOES-16 Water Vapor imagery (below)<\/strong><\/em>.<\/p>\n
