Lake-Effect Snow — Oswego, New York

2025-01-23 to 2025-01-25 · Oswego, New York

Wider weather episode

With cold temperatures aloft (-14 degrees Celsius) and as a pre-frontal trough crossed the region, lake effect snow developed off of both lakes during the evening of January 23rd. Westerly flow between the passing trough and the cold front that crosses the region later that night resulted in most of the snow to focus on areas directly east of the lakes. Behind the passing cold front, northwest flow caused the lake effect snow to shift southeast of the lakes during the morning of January 24th; and from there the lake bands were less organized and movement of the lake bands limited most of the snowfall for any given location/area. Snowfall amounts for this short event weren't overly impressive, but the greatest snowfall with this lake effect snow occurred east of Lake Ontario.

Snowfall amounts for this event include: 14.8 inches in Lacona, 10.5 inches in Richland, 9.5 inches in Fulton, 9.0 inches in Barnes Corners and 9.0 inches in Hooker.
