    A powerful lake-effect snowstorm fueled by record-warm water temperatures in the Great Lakes unleashed its full force over 2024 Thanksgiving weekend in the United States, burying parts of New York, Pennsylvania, and Michigan under more than 90 cm (3 feet) of snow. The city of Erie, Pennsylvania, experienced its snowiest day on record on Friday, November 29, receiving 57.4 cm (22.6 inches) of snow in 24 hours. The Arctic air colliding with the warm lake waters triggered intense snowfall rates of up to 100 mm (4 inches) per hour, creating hazardous conditions that are expected to persist until midweek.
