I always got frustrated when I talked to people I know about this. I used to tell them look at the departures across the 1st order stations in SNE. How can one station be over 2F above the rest. The airmass doesn't magically change inside 128 lol. But people would still push back on it claiming UHI...but it doesn't work like that. Having over 2F difference in departures compared to other stations is statistically significant with this kind of data. Local micro climates aren't enough to explain it. Something was up there. Oh well.
