COMET_CASE_032: COMET Case Study 032:Buffalo Lake Effect Snowstorm


On 20 November 2000, Buffalo, NY was hit with a lake effect snowstorm with strength unseen in several years, and a disruptive force unequalled in nearly 25 years.Buffalo received 2 feet of snow in a relatively short time, with most falling in a 7-hour period. Frequent lightning occurred all afternoon with this snowfall, and the timing could not have been worse, as the brunt of the snowfall began around 2 p.m. local time. Many people spent the night in autos, and buses full of school children were trapped, eventually spending the night in stores or makeshift shelters.


This case allows the study of a classic severe lake effect snowstorm.
