A strong cold front initiated a broken line of snow squalls to the region. The snow squalls developed in the afternoon across  the Lower Hudson Valley and then quickly moved east through the NYC metro and western Long Island during the evening commute. The snow squalls weakened as they moved across eastern Long Island. While snowfall accumulations were generally under an inch, the squalls brought strong winds and whiteout conditions. Traffic was brought to a standstill during the squalls and created life-threatening travel.
