A number of historic level extratropical cyclones occurred along the Northeast coast during the latter 19th century. However because of the limited technology of this period only surface data were available. This paper will focus on the extrapolation of the 500 GPH fields for such weather events through the composite analysis of modern extratropical cyclones with similar characteristics in which 500 GPH field data were available. Through this analysis a composite 500 GPH field pattern can be determined for the historic cyclone in question. In addition paradigms of dynamic meteorology can be applied to further develop the extrapolation. This technique can be an effective tool for undergraduate and graduate students to develop a deeper understanding of the dynamics and synpotic patterns associated with major extratropical cyclones along the Northeast Coast of the U.S. The Blizzard of 1888 will be used as a working model.
