13.6 trillion gallons of water fell on the 5 state region (Florida, Georgia, North/South Carolina and Virginia) from Hurricane Matthew. This amounts to only 1% of the total rainfall across the continental United States this year. Hat tip: Ryan Maue

Here is how you would calculate this:
Ohio covers 44,852 square miles. This is roughly 1,250,400,000,000 square feet
Convert 14 trillion gallons of water to cubic feet gives us 1,818,055,555,556 cubic feet
Divide the two and convert to inches yields roughly 17 inches of water over the entire state of Ohio.
In order to convert the water to snowfall, we need the snow ratio. That is the amount of snow per one inch of liquid. The problem is lake effect snow can have a ratio from 20 to 1 to almost 40 to 1 depending a variety of factors. So let's take the lower conservative end: 20 to 1.
This gives us......drum roll please...
28 feet of lake effect snow over the the entire state of Ohio
