"The purpose of this study is to analyze snowfalls associated with Lake Champlain with the use of Doppler radar data, Geostationary Operational Environmental Satellite (GOES-8) data, and high resolution numerical output from the Meso-Eta (Black 1994) model. The impact of these snowfalls can be as great as synoptic scale storms. The most common result of arctic air crossing the relatively warmer Lake Champlain is low clouds and flurries. However, on rare occasions snow squalls with visibilities less than a 1/4-mile and up to 33-cm (13 inches) of pure lake effect snow in a 12-h period have been observed. This paper will explore events which fit the category of lake effect or lake enhanced, and develop criteria for forecasting them"--Introduction.
