The melting of ice on Lake Erie has led to a return of scattered lake-effect snow showers in northeastern Ohio, after a stretch of warmer temperatures in the region.

Why it matters

Lake-effect snow is a common weather pattern in areas near the Great Lakes, but its presence and intensity can vary significantly depending on the amount of ice cover on the lakes. The return of this weather phenomenon signals a shift in regional climate patterns.

The details

As the ice on Lake Erie has melted, the open water has begun to interact with cold air masses, creating the conditions for lake-effect snow showers. This type of snow is produced when cold air moves over the relatively warmer lake water, picking up moisture and then dumping it as snow on the downwind shores.
