So what does this mean? Well for starters the risk factor has gone up for anyone taking advantage of this season's early lake freeze. Although most of the ice we have now is pretty good, there are hazards. Big temperature swings can have substantial influence on the ice but in addition to actual changes to the ice there is the danger of recently frozen thin ice that is now being obscured by the recent snow/rainfall.
For example, Silver Lake. I think this is the earliest I've ever seen it freeze over and the ice on most of the lake varies from 2.5" to almost 8" or good black ice. However off Hurricane point and near the Northern Islands there are large patches of water (red area) surrounded by large patches of ice (yellow area) that have formed within the last 24 hrs. This ice looks much like the thicker ice and was hard to spot yesterday.
It will be impossible to see now.
I will do an update on the conditions hopefully sometime withing the next 24hrs. Stay tuned.
