Good question.
Boy, a foot or more huh? I was going to answer maybe on a line from about Manitowish Waters to somewhere between Lando and Watersmeet, but you talk about Lando and Phelps getting hammered, so that caught me by surprise. So I would have to say that the Lando-Phelps area would be about as far south as I can imagine the heavy LES reaching and even further south than I would have thought.
I can't say for sure why Bruce Crossing seems to get less than places like Kenton and Sidnaw, other than perhaps Kenton and Sidnaw are higher in elevation and that just squeezes out the last bit of moisture from the LES clouds. Any LES hitting Bruce also has to travel over the Norwitch bluffs, which might suck most of the moisture out, but Kenton and Sidnaw also are down wind from the higher terrain around Twin Lakes. So it is a bit of a mystery. Bergland is actually closer to the lake than Bruce is, so that would explain why they do better than Bruce.
I know back in about 2001, I was on my way back from southern WI visiting for Christmas and encountered LES snow in Merrill. It was just flurries, but LES none the less. Got to Rhinelander and it was snowing hard enough to accumulate a bit. Got to Eagle River and they had around 4-5" of LES and it was coming down even harder. I began to worry about what the heck I was driving into. The LES kept intensifying as I drove north and by the time I reached Mass City, I could barely see past my hood (no joke). I was driving about 5 miles per hour and wondering if I should just turn around and beg to stay with friends that own Club 45 in Conover, as things get pretty lonely between Mass and Twin Lakes. Just then, I saw a car coming from the other direction on 26, so I figured things must be better up the road and decided to press on. It was coming down so hard though (4-6"/hr) and there was already about 6-8" on the road that if it did not lighten up soon, the snow would be too deep for me to continue on and I would be snowbound in my vehicle with Burt and Baileys. As luck would have it, the snows did lighten up around the Firesteel Rivers and I made it home, but it was a close one!
