A storm currently moving across Canada will bring lake-effect rain and other hazards to at least a dozen U.S. states on Wednesday, a National Weather Service (NWS) forecast said.

The unsettled weather will persist through Friday.

Why It Matters

While the "lake effect" is more common with snow across the Great Lakes region through the fall and winter months , it can cause rain when temperatures are warm enough.

Meteorologist Liz Jurkowski, who works at the NWS Buffalo office in New York, told Newsweek that lake-effect rain goes through the same process as lake-effect snow, with cold air passing over the warm lakes causing precipitation.

"It's basically the exact same thing as lake-effect snow , but it's warm enough it's going to be falling as rain," she said.
