I've seen local studies discussing the development of a nocturnal southerly jet on the VT side of Lake Champlain, being funneled up between the cooler lake waters and the Green Mountain Spine.
You can see Plattsburgh, NY (PBG) on the NY side of the lake was calm all night with mist/fog and got down to 68F.
However, at a time of the night when all other sites are showing calm, BTV is actually seeing increasing wind.
This is some tropical stuff. Breeze actually peaks in the 4am hour when most other sites are hitting their minimums for the night. It's like the wind increases to fight off any possible decoupling.
