I went up to check out Willoughby this morning. Based on Ben's report, there had been some flurries during the night, which had partially blown off and it was beginning to snow as I arrived. I went out at the boat ramp at the same place that Ben had checked, I found some smaller plates of 2 1/2 inch ice, larger plates of 2 inch ice but the further out I went the thinner they got, a lot of it was sub 2 inch ice with some plates that I checked at just a little over an inch. Boundary lines were visible, which was why I was able to check these plates. The ice quality is 10th grade black Ice, not a whisperer of chatter from the skates.
The whole northern Half looks pretty similar, just a couple small wind holes. The middle of the lake is riddled with wind holes and there are big open holes on the southern end.
It is predicted to be calm for several days up there so there's probably not much chance the snow will completely blow off but you never know it Willoughby. It's supposed to be 1° tonight and -10 tomorrow night so there may be new black ice on the big open areas on the southern part of the lake as of Monday morning. more snow coming in Monday afternoon. So I think Monday morning is probably the best bet, it is going to be quite cold so hopefully even that ice that has some snow on it will thicken a little but take care on any ice that has snow because it may not thicken much.
I also skated a nice little zone between the old rubble, Ice and the new rubble band on the south end 2+ inches. Although there are thin plates down there as well. All in all, it was a nice two or three hour skate over not a large area but on amazing ice.
