While the point of that map is certainly accurate, the numbers are skewed up because of the stations that they are using. Locally, KPDK was +1.8, Fulton County was +1.5, Dallas, GA was +1, and Gainesville was +2.
Gainesville airport seems warmer than it should be a lot of times also. It's been that way for 20 years. Not sure why because it's not the UHI.
Well some of it is definitely due to overall global warming, but I would attribute some to UHI. Hall County has been engulfed by the Atlanta megalopolis and tripled in population during that time, so I would definitely attribute a fraction to that alone.
Many times Gainesville is warmer than the Atlanta airport. The only time that should be the case sometimes is when there's winds coming off the mountains and warming the area which does happen.
Gainesville honestly mirrors my weather station almost exactly, and I've shown on here what my station does on radiational cooling situations. The temp drops rapidly at sunset until around 10PM, then fluctuates up and down until around 6, then drops a few degrees. This temp fluctuation is like clockwork on calm nights. I think it has to do with topography, and Gainesville sits on the ridge that basically follows I-985 from SW to NE, which is about 400' higher then areas southeast. The other caveat is Lake Lanier, but its been there since the 1960s. This is me only speculating based on what the readings are at my location. There are places less then two miles form me 150' lower that can be as much as 5-7 degrees colder then me at night.
Yeah that's a lot of truth right there I would say. I know one thing's for sure if there's a cad I'd rather be in Gainesville than anywhere else in the area.

Yep. I've been dry slotted nearly every time.
