I'm not aware of any. They did have numerous 3kt obs overnight so maybe it was slightly more mixed? 3kt isn't a hell of a lot though...especially at an airport. Sometimes that's just drainage flow too. CEF did have dews in the low 40s while BDL was upper 40s. I'm not sure how "real" that is or if it even mattered, but maybe that's an explanation. Aside from that, I haven't followed BDL and CEF enough to really get a feel for the rad cooling trends between the two. I guess it's something to keep an eye on in the coming months.
What would you have expected at BDL given the 47.5F at CEF?
