It was like 39.9 in the 81-10 data set lol! Hardly much of a change but yeah it takes away the novelty of saying we have 4 months with avg lows sub 40. Now its just 3 and Jan is .2 from breaking freezing.

Pro tip- One good way to tell how much UHI a place has is to compare its avg dews to the avg low. They should essentially be on top of each other, if the low is way higher than the other sure fire way of telling theres a crap ton of UHI.
Ah...for some reason I thought it was a bit lower. Makes March seem less wintry when we’re talking about average lows in the 40s. At least it probably takes until around mid-March for that to happen.

Here is one I think you guys will like a lot. @GeorgiaGirl show this to your dad I know he would love these links and the boxes some people on another forum im on made interpreting raleighs climate during the ice age from them roughly. These values wont be exact as this is all interpolated data but it should be close, during the ice age climates varied widely. The further north you were the more different from todays climate it was where as the further south you went the less change, Florida and especially south florida were not that much colder than today. Miami was still a very very warm climate even during the ice age, cooler winters and summers but nothing as drastically different as we see for Raleigh and especially places even further north. This is the post of the year right here for yall snow weenies . @SD @Bham 99 @Sleet City USA @superjames1992. I deserve an award for this post because I just satisfied every weenies biggest question, what was it like during the ice age?
Means roughly using NCAR data set
Raleigh means ( not avg highs/lows but means). Essentially a very solid Dfb climate, not quite subarctic as both May and Sep were still much higher than the 50 degree mean cut off. Looks a lot like a modern day climate in New England or Eastern Canada. Im dubious of the precip data as conventional knowledge is it was much drier during the ice age, but of course that winter precip would be snow mostly lol. Keep in mind its harder to get a good idea if the location is closer to water as you can see the water is much warmer lol. Luckily Raleigh is inland so this should be a safe bet, and elevation doesnt change drastically so the smoothed over grid should be good.
Heres another fun box estimating Raleighs climate from a different ice age data set. This one has holocene optimum as well, would be interesting to see the climate then. Summers would have been a good bit hotter I bet relative to today given the sun was further overhead on the solstice. The person also did OKC, theres a few more we made if yall want to see. I think he overdid the snow for raleigh, modern day climes in our warmer wetter times with those averages in the eastern us arent that snowy. The records are obviously just guesses based on modern day equivalents.
Heres the modern day equivalent of ice age Raleigh. Berlin is a frost hollow however, pretty well known cold spot in NH, so may not be best gauge of what kind of records to expect.

Well you got to figure with the ice sheet several hundred miles north where temps in summer would barely be above freezing you can imagine Raleigh would be chilly. Cypress trees where also everywhere in NC due to the much colder climate.

Really good stuff here. Not much else for me to say outside of that other than it would definitely have been nice to experience a cooler climate.
My dad would probably have more commentary, I have likely read at least some of his Ice Age research but my memory is just trash lol.

I've read a lot of his stuff. He is a cheeky fellow as well lol, I remember reading an article about neanderthals that he wrote and his example of what they looked like was some hot naked redhead which he posted a pic of lmao! His dream if I remember correctly is to live in Ice age coastal georgia among the mega fauna! He also posted lots about his trips across the south !

Interesting that the number of days with highs and lows below freezing also went up at GSO, RDU, and FAY with the new climate normals, despite average temperatures overall increasing. Of course, number of days with highs in the 90s went up by even more.

I saw that , it actually went down not up . I know this sounds weird but there’s ------- different values even for that ---- too. I’ve seen 2 diff values from NCEI for the 81-10 days below freezing . If you look at raw it went down as well. Smh none of it makes sense lol. It went up in your comparison because they are comparing the raw one to whatever that second number will be which comes out in the stupid annual summary each year . That’s where I find that information.
Raw to raw makes sense , why can’t we just use raw data .
Here are some of our higher elevation stations in the region:
Caesars Head, SC
Georgia doesn't have any official reporting stations on any of their peaks listed, which is annoying. Here is the highest city in the metro area at 1500', Jasper.
Mt. Mitchell, NC
Beech Mt, NC
Mt. Leconte, TN

These have me digging into the ol memory. I think the 2 in 94 was supposed to be below 0. I remember Fishel talking about how hard it was for our area to stay in the teens low 20s during the day in full sun. The 0 in 96 probably came after the big ice/snow event which was one of the coolest events that doesn't get talked about enough.
Really I would have expected there to be more lows 0-5 to be honest. Kind of goes to show how hard it is for us to get extreme cold around here

That 11 in March would crush my soul. Looking forward to spring rolling in, and BAM, Old man Winter swings with a wild right hook.
