Growing up in southwestern and then central Ohio I will confirm for you that the same excruciating misses on the margins occurs for midwest cutters as it does for us. So many times in the mid-1980s forecast 6-10 inch snows for me just east of Columbus would end up two counties north. We just don't notice for the reasons you said.
As for whether the presence of cutters in the longer term is more stable, maybe? But there is a huge difference in a cutter at 7 days that is modeled through north dakota and at game time ended up in eastern Ohio - but we don't follow those swings that closely either
TL/DR - WxUSAF is right.
