Marine Thunderstorm Wind — Sodus Bay To Mexico Bay Ny, Lake Ontario

2021-03-26 · near Oswego, Sodus Bay To Mexico Bay Ny, Lake Ontario

Wider weather episode

A compact closed low passed just to the northwest of the area. Accompanying this system, a strong and well-mixed low-level jet advanced just to the east of Lake Erie. This was an unusual system since it originated in the southern branch of the jet stream and was already a closed mid-level low. This did not fit the pattern of what typically causes strong winds in our area, but it certainly did cause very strong winds with lots of damage and numerous measured gusts over 60 mph. There seemed to be a favorable environment for funneling along the Chautauqua Ridge and across the Niagara Frontier, as those were the locations with the strongest large scale wind gusts. Ahead of the cold front, early morning convection affect the Lake Erie shoreline as well as the Buffalo area, convection redeveloped in the afternoon over the North Country with discrete cells resulting in concentrated damage in Lewis County.
