This is from Rockaway on Tuesday

31 degrees out currently. Much to be thankful for. Wishing everyone a wonderful day!

Happy Thanksgiving everyone! It's going to be a great weather day here with sun and temps in the upper 30s. This beast of a clipper is still showing up here on Saturday.

I doubt it would mix out the inversion (you generally don’t have low elevation fog under a well mixed boundary layer). I think it’s more likely the latent heat release from condensation warmed the air, but that saturated airmass itself was cooling in the absence of insolation, so when it arrived/formed at your location you saw the temp spike then the resumption of gradual cooling when radiative equilibrium was reached again.
