The system that brought widespread ice to parts of southern Ontario last weekend painted a slightly different path across the northeastern United States. Snowfall across Upstate New York surged into the record books, with Albany seeing its 8th biggest snowstorm on record as nearly two feet (61 cm) of snow fell over three days.
The charts have been updated for Albany snowstorms with December 1-3, 2019 in the record books as 8th biggest snowstorm of ALL-TIME and the 4th biggest for December. Local climate data/records: https://t.co/batzIOZEpf #518wx #nywxNWS Albany on Twitter
An active storm track for eastern Canada also favours winter storms in the U.S. Northeast, particularly when it brings a series of Colorado lows up across the Midwest and Great Lakes.
It seemed to snow forever in Albany, NY with this storm: Snow was reported for 39 straight hours. That's tied for the 8th longest run in ALB history (since 1948). Incredibly, it snowed 48 hours straight in Jan 1983 (24.5") and 46 hours 3 weeks later!Jase Bernhardt on Twitter
