Yesterday the ice absorbed a lot of heat from the air. This was evident in the fact that Concord, Rochester and Lebanon all got into the 80s while Laconia was 75 and Black Cat Island was 70. That only occurred for a short time when the wind dropped off to calm. As soon as the lake breeze went from zero to 2 mph, the temp dropped off quickly to 60.

Most people would say "the ice was cooling the air" which in reality means "The ice has absorbed heat from the air, leaving the air with less heat." In physics there's no such thing as "cold," only "heat." When conditions cause our bodies to lose more heat than we're making, we call it cold.

But anyway... there was a 20-degree difference between the lake and the surrounding area yesterday. That shows the ice absorbed a LOT of heat yesterday. I could even see the "heat ripples" coming off the ice on the horizon.

The same thing is happening right now. Laconia is 73, while the WeatherCam is 58. The ice is eating heat like a mafia target who's drinking cyanide.
