The daily atmospheric systems and weather fronts that traversed the northeastern United States during the SNOW-ONE-A Field Experiment from 30 November to 20 December 1981 and from 3 January to 10 February 1982 are summarized. This experiment is the second of a series of winter measurements of the influence of atmospheric obscurants on electro-optical system performance. The analysis of the large-scale synoptic weather patterns that developed during the field test period constitutes a critical component of the research program. Precipitation in northern Vermont during SNOW-ONE-A was near normal for the region. Numerous separate snowfall events, including some with substantial amounts of snow, were recorded during the experiment period. Almost all of the storm that produced more than 6 cm of snow resulted from coastal cyclogenesis or developing waves that deepened as they moved north or northeastward along the Atlantic coastline. The majority of the other events with lighter amounts of freezing precipitation were caused by less intense storm systems, troughs, or fronts that traversed the region from the west or northwest and often moved quite rapidly.
