Believe it or not, yesterday morning was even more so! The data is now in and the Battery was only 4C compared to the -3C at the Charleston Airport, I've never seen a difference so large between them!
Could be that the Battery had more wind
, I remember from Charleston Airport staying 3C warmer than Savannah Airport on November 29-30 that wind differences can reverse or exacerbate radiational differences and it's easy to see that happening here.
And although their substantial differences are in spite of their closer distance than Savannah Airport and Tybee Island (which as I've postulated before probably has to do with the fact that Charleston's Battery station is literally right on the immediate coast while even Tybee's is not), in the Southeast US you lose out on maritime influence during radiational events very rapidly when you are not on the immediate coast, so once a station is inland by a certain point it doesn't really make much or any difference as to whether it is just past the no maritime influence threshold, or many kilometers away.

That station that you have highlighted for Tybee is in fact the Crab Shack restaurant. I did not know they were the ones recording their own weather! I've eaten there several times over the past few years. Their crab legs are delicious!

Thank you for that little story lol
. I did not know they were the Crab Shack restaurant, glad you enjoyed those crab legs.
Maybe one day I can get in on the action too
! Although I am still not certain as to whether this is possible, in the future I
may be able to visit Tallahassee and collaborate with meteorology professor Henry Fuelberg to set up some weather stations in the pine forest that can be compared to cold hole KTLH (and to the Challenger Learning Center).
If that is successful, when I fly back to Atlanta from Tallahassee, I might as well take a moment to go to Tybee Island before going home to try a bite of those mouthwatering-sounding crab legs in your honor.
Speaking of other places like Tallahassee:
-The coldest KTLH has gotten so far is -4C, same as the Challenger Learning Center, since the most powerful cold front has been advective. I'm not specifically hoping for this (because the odds are so low and I have the pretty much guaranteed-to-do-well Challenger Learning Center), but given the similar advective cold front and the similar February forecast this may end up as similar to 2015, which KTLH lucked out for and did notably well.
As for the Challenger Learning Center, I wonder if it will get frost in February. Literally the only February to get some since it started in 2014 was February 2015, and since this looks similar as mentioned above, it could.
-Ocracoke data is now in. They reached -2C on January 17, for years with data that 346 day frost-free season is the longest ever!
-Sapelo Island, unless they got lucky with wind or cloud cover, most likely had frost already like alluded to in past comments. No data past January 8 but January 3 got to 1C and it was much tamer than January 17-18.
So it looks like Charleston's Battery is the only non-Florida station that is frost-free, unless we can find some lucky wunderground spots.
