 While having very similar snow totals in its aftermaths, the origins were very different.The first blizzard developed out of a large upper-level low moving into the Southwestern United States, drawing a huge amount of moisture with it.It began to track towards the east, and then merged with an incoming weaker system from the north, on February 5, the two systems phased together, resulting in a band of heavy snow across Illinois, Indiana, Ohio, and Pennsylvania.
