TOLEDO, Ohio (WTVG) – In the Pacific Ocean, trade winds normally blow to the west along the equator. This takes warm water towards Asia and allows cool water to rise from the depths of the ocean – a process called upwelling.

La Niña is a climate pattern that happens when these trade winds are more intense. They push more warm water, allowing more cold water to rise to the surface. These cold waters push the jet stream northward. This tends to bring warmer and drier conditions to the southern U.S. and cooler, wetter conditions to the north.
Its effects are strongest during the winter season. The increased chance of colder temperatures and wetter conditions also translates into a higher likelihood of snow across the northern U.S. and Midwest. Historically, during years under a La Niña pattern, snowfall amounts were recorded above normal across the state of Michigan and northern and central Ohio.
Although weak La Nina winters led to snowfall amounts below normal across Northwest Ohio and Southeastern Michigan. Our La Niña conditions are currently weak and are expected to stay weak, but last into February.
There is an equal chance of seeing temperatures either below, near, or above normal this winter. There is a better chance of wetter than average conditions across the Great Lakes region.
In summary, there is a strong likelihood of wetter conditions in Southeastern Michigan and Northwest Ohio this winter. How much snow we receive is going to come down to our temperatures throughout the winter season.
