West wind for a change!
This evening we have seen a change in the weather. The southeast lake breeze of the past several days has now shifted into the west. This will mean much warmer weather for tomorrow since it is a breeze from off the continent instead of the ocean. For most of NH south and east of the Appalachian Mountains, it also means warmer by pressure. Air heats up due to increased pressure as it loses elevation, and we'll be getting some of that tomorrow, too.
Since most locations around here were in the upper 70s today (including Laconia), I am guessing mid-80s will be pretty common for tomorrow. This combined with two different wind directions expected (SW shifting to NW) should stir the ice around, keep it moving instead of crammed up against one side of the lake, and may well result in iceout tomorrow.
Even at this late hour the surface water temp at Black Cat WeatherCam is holding at 39 degrees, and the dewpoint isn't much lower than the temperature so there's not a whole lot of evaporation cooling that can take place on the lake tonight. Should serve as a springboard to push the water temp above 40 tomorrow with summer weather and even a chance of a thunderstorm in the evening. A few places may have them but not everyone.
