I'm wondering how you think the climate of North America would change if all the Great Plains were a giant inland sea that connected with the Gulf of Mexico and went all the way up to the Canadian prairies today. Let's say that this sea was not all that deep relatively speaking with the deepest parts around 100 metres (330 feet). I think millions of years ago, this was the case anyway.
The sea would be roughly the size in this image with a small outlet to the Gulf of Mexico
How far south do you think this sea effect snow would occur?
Probably down to around Omaha or Kansas City on a regular basis, becoming rare south of that. But it could theoretically occur all the way to the Gulf Of Mexico, like it did in the Great Blizzard of 1899.

In a situation with a large inland sea no further south than Chicago will it be a common occurence.
Winds out of the west and northwest are common in the winter in both locations. Although Kansas City's lack of areas that would cause large amounts of orographic lift may reduce snowfall totals somewhat, I see nothing there that would stop it from occurring there at least once each year.
