Up to 4 feet of snow is expected downwind of Lake Erie and Lake Ontario, making for a very wintry scene during the first weekend of 2025. Due to a wave of bitterly cold air, lake-effect snow started downwind of the Great Lakes during the middle of this week. The wind direction has shifted around slightly, but the cold air has persisted, giving many in the lake-effect belt a sprinkling of snow while burying others.
