700 mb heights, frontogenesis and temperatureNotes:At 700 mb, a short wave was forecast to move northeast from the Ohio Valley toward the northeast. The 700 mb low center tracked across the eastern Great Lakes early on the 5th, well to the west of the area of heaviest snowfall. The structure of the 700 mb low transitioned from a closed low to an open wave as it tracked northeast. However, a pronounced area of frontogenesis developed in the northeast quadrant of the system in area characterized by diffluence and a strong temperature gradient.This area of frontogenesis tracked from upstate New York northeast across New England.
