Yeah! That’s what I mean when talking about the nocturnal jet that sets up there out of the south. I don’t have the study or write-up handy but in the last decade they’ve found evidence of a nocturnal low level jet on the VT side of the lake where air is routed north between the cooler, stable lake air and the Green Mountain Spine. And at night they have a lowering inversion or less mixing in adjacent areas I guess, resulting in higher surface wind speeds in a corridor from Addison County up through Franklin County on the VT side of the lake. Places like Plattsburgh, NY and NY side of lake seem to run slower wind, cooler temps.
You’ll see BTV almost get windier or stay at similar levels at night when other stations drop off. Their temps reflect the mixed atmosphere without insolation. I love that mesoscale stuff.
