Weak low pressure tracked offshore of the mid-Atlantic on February 13, spreading some light precipitation into the region. A surge of warm air aloft prevented the light precipitation from falling as snow. However, strong high pressure to the north promoted a cold air damming environment with sub-freezing air trapped at the surface. This led to most of the precipitation falling as freezing rain, with some generally light ice accretion across the area.
