Mark, how near the lake are you going to be? It's a bit of a relative statement. Steve lives in NY so I could tell him that I live near the lake too, even though I'm 30 miles away.
Steve's post gives some excellent info. But I'm not sure how it will relate to being "very close" to Lake Superior. My thinking is that the closer you are to the lake the more of a chance there will be that the thermals will be rising as the lake will be warmer than the air. That said, I don't know what effect the lake will have on pushing your scent inland.
If you have the time you might try and go out a couple of mornings and lighting an incense to see where the smoke goes. If your hunting very close to home, a small campfire will show you even better.
On the other hand, an inversion could occur in which case the biggest factor will be the direction of the air current.
