This thread was bumped at literally the perfect time for making a couple of list updates to reflect what the 2022-23 winter taught me about the places on it.

I should specify what I mean. Not only does Dallas obviously have great first and last frost monitoring, it has what I would say is the very best wintertime heat monitoring in the Southeast US relative to averages.
From December 21-March 20 the normal monthly maxima are 24.8C/15C to 29.9C/18C - whereas the averages for those days are 14.3C/3.3C to 21.8C/10.4C. Don't know of anywhere else in the Southeast US that averages this.
It also means monitoring treats here and now even in averages months. This February was close to normal but had a monthly maximum 4.1C above the usual of 26.9C that was sure fun to see firsthand.

I'm starting to like Charleston a bit more compared to Dallas. Dallas Love Field losing its contest with Charleston Int'l is not always a bad thing as this year taught me, as that can end up meaning extra good for both.
This year Charleston Int'l got January 28 to February 18 for Dallas Love Field. It may be a technical lose, but unlike the previous first frost season where Charleston Int'l got desirable December 23 to Dallas Love Field's undesirable November 20, it's a win win in terms of good dates for both, and January 28 is a great date in general for Charleston Int'l too.
[quote=Can't think of username;64782366]-Outer Banks. Even-more-remarkably good monitoring time given their averages and especially latitude, with frostless winters occasionally being possible for the ultimate monitoring treat.
There are times when they can handle advective cold much better than their latitude would suggest. This past Christmas cold front is a very good example, they only got slightly below the usual coldest seasonal low (-6C vs -5.2C) compared to many other places from the Carolinas to Texas and everywhere in between that got off WAY worse, and for this they get the obligatory rank increase.

And what got me interested, the cold hole airport, can from time to time perform pretty damn well which is well worth watching out for.

Scratch this statement to an extent both ways. As I've said in other threads it turns out the Tallahassee airport is essentially just a colder artificial Archbold Station, and delegated appropriately to an afterthought that will only be monitored on cloudy/windy/very very very mild winters.
It is artificial because the cause is artificial deforestation where the weather station is, this increases soil drainage and radiational cooling WAY past what the natural environment would have. All airports in the Southeast US have this problem but Tallahassee's is unbelievably disproportionate as Elsner et al. 1996 and 1998 have found.
The other way is FSU Tallahassee that I am making some normals for, it is similar to other warm Interstate 10 sites like Houston Hobby Airport and New Orleans but for a completely different reason to both. This has me even more interested in it than I was interested in the airport when I made this thread.
Unlike Houston Hobby and New Orleans, downtown Tallahassee is inland and does not have a very big heat island despite its fantastic performance - its good performance has pretty unique causes. The soil is wet clay which is considerably less prone to radiational cooling than the well drained sandy soil of the airport,
and the FSU station is at an elevation of 48m above its lowest surroundings in a hilly area, giving it 48m worth of cold air drainage (for perspective 2m is enough for a 2-3C increase in radiational cooling lows).
And to top it all off, where they are located gets almost entirely radiational cooling which allows what they have going for them to shine almost all the time.
The result? Since the station started recording in June 2014, the only month to record frost with any kind of regularity is January and there has even been a winter without a frost, very similar of course to the 2 sites mentioned above.
Relative to the airport it's mind blowing. The most common discrepancy between them on those radiational cooling nights is easily 5-6C, and I have seen differences of up to 9C, but never a difference under 4C.
Last but not least the wet clay soil actually makes FSU colder than the airport with regards to winter heat despite the way warmer lows. Most hot winter days are sunny, allowing the sand to heat up much more than the clay and create fascinating-both-ways discrepancies when comparing the full monthly data.

This winter was proof of that. Despite being a cold hole the airport is not as prone to radiational cooling as other cold holes for some glorious reason, and its low latitude means that despite its inland location it can get off easy from advective cold.
For example, during the advective Christmas cold the Gainesville airport got to -5C, pretty much exactly as cold as would be expected for the season (usual -5.1C). This is considerably better than the much closer to the coast Jacksonville airport that is around 1 1/2 degrees latitude further north and would be expected to do better on paper, it got to -7C which was 2.3C below the usual coldest of the season.
And on the 16th and 21st of this month during large radiational cooling events, they only got to 1-2C instead of getting frost like one might expect. This means their last frost this season is a fabulous January 28.

Daniel Field performed poorly this season for both of those categories, and downtown Augusta had a freak 8a winter instead of a 9b winter as would be expected, but downtown had an AMAZING last frost compared to Daniel Field which was unexpected.
Daniel Field got a dumb March 20 last frost this season while downtown was lucky enough to get January 14 with 1C misses this month and a VERY lucky 0.1C near miss last February. Looks like they were literally the perfect amount warmer than Daniel Field to perform well.
Last but not least, there's something more that would be relevant to what hunters1212 said.
Because Louisiana had dumb very backloaded last frosts this year on the equinox that just so happened to also be the time a user from Chemnitz Germany commented on the last frost thread about a possible March 16 last frost, I held a Germany/Louisiana contest for last frost to make some fun out of the dumb backload, and will continue to do so during later seasons, hopefully good ones for Louisiana.
Now Germany is still very boring to monitor compared to the Southeast US such as Louisiana of course, but this is directly dealing with Europe and the Southeast US like was mentioned and does add some funny variety to a well timed comment.
The Louisiana place I wouldn't mind losing, by the way, is Minden to Minden Germany.
