This year, there are some different processes eroding the lake ice, other than direct warmth-on-ice. Today on a south-facing shore I saw the sun had melted away all the snow on an exposed part of the shore, and the resulting meltwater had flowed into the lake, eroding the ice right at that spot.

I would also guess that weakening will occur as the flow gets going from all the meltwater we'll have soon... runoff in, dam water out...

Since we are in an active weather pattern there is also good chance that a storm will take it out, like last year. Had it not been for the April 16 storm with its 64-mph wind gust (sustained at 45 mph for a couple of hours), last year's ice would've lasted a lot longer I think. It got busted up by force and 80-degree temps melted the pieces a few days later.
