Yes, it's like if Ole Man Winter over reaches his bounds and attempts to dive too far south, the effect is opposite of what he was trying to achieve... Ole Man Winter is better off trying to stall out in the mid south where humidity and cold can combine if he wants to achieve the most wintery conditions possible in the deep south. Dry arctic air doesn't do much to the south, except make the winter very mild. It's those dry arctic fronts that can sometimes bring 80 degree days to south Texas and south Florida. Pacific fronts, in contrast almost always bring mid 50's and rainy temps which are actually colder...
That's that dry, cold, high-daily-range air that is typical of the southern extent of big cold fronts. The coldest weather overall is brought in by the combination of arctic air in place with an incoming moisture-laden storm, such as the huge snow/ice storm in Texas last November.

Isn't that counter-intuitive to those from northern climates?
Not at all; it's just that in the North they experience that phenomenon in Summer (or early Fall/late Spring) rather than Winter.
"Although Wind Chills values aren't "as" cold as yesterday morning and the Wind Chill Advisory has been dropped.... it is still cold out there (A balmy 6.8 degrees for balloon launch)!! Take a look at the wind chill readings from 6AM this morning!"
Why don't you post the daily highs too? This is to show how extreme dry arctic air is moderated greatly in the south in the day.
Tampa high of 63 today
New Orleans high of 55 today
Miami high of 70 today

We got another stall out pattern in December and we're getting one today and tomorrow. Austin never got any ice from the last two storms (Dallas did, but we were above freezing then) but they are predicting possible snow tonight. High tomorrow only in the 30's due to overrunning, then the arctic front penetrates and the next day will be 66 and then 75!
It's actually less painful to just allow the arctic fronts to penetrate all the way south, then the bone dry air will warm up and give us nice 70 degree days in winter... When the Gulf of Mexico puts up a fight, that's when we get our coldest weather, like today and tomorrow.
But cold never lasts more than a couple days here before it is modified...
Great graphic, the Deep South is clearly viewable just looking at the temps. The moderate West Coast is also viewable.
