A conceptual model detailing the processes associated with heavy banded snowfall in the presence of an extratropical cyclones (ETC) was presented. These processes act synergistically to focus vertical motion, deep layer moisture and instability over a mesoscale zone. The processes associated with heavy banded snowfall was used to determine a liquid equivalent forecast (QPF), but a snow to liquid equivalent ratio must be utilized to determine a snowfall amount. The vertical profiles of temperature and moisture were analyzed, providing the type of ice crystals that likely formed.
