So it appears that we're reaching the point where the colder and warmer layers are mixing to create a uniform temp from top to bottom, which happens for a short period in the Spring.
This all has to do with the density of water. Pure water is most dense at 39.2 degrees F. When the water well below the surface goes over 39.2 degrees, it floats to the top slowly displacing the cooler water close to the surface. People call it flipping. Once the lake flips, the ice melts very fast from the bottom up. CLAs two probes, on his Black Cat weather site, clearly are showing this process yesterday and today.

I am now thinking this weekend will be ice-out, but I have been wrong before.
