Current forecasts shows lows in the upper 40's and highs in the mid to upper 60's. Unfortunately, living up here that means nothing unless you factor the wind in. If there's a nice 15mph wind blowing off the lake, you could need a snowsuit . Layering indeed is the only way to go, especially on the boat. I'm just praying we don't get rain, especially the thunderstorms that rolled through for an hour this morning.
