You do realize all the models point to either a very weak Nina or even neutral conditions. Don't count on any big ridge in the Southeast due to a Nina.
Look at the warm waters and the strength the Ridge all ready has right now. All we need is the Bermuda high which normally becomes the azores high in winter near Europe bringing them stable conditions and when it's near us as the Bermuda high it does the same.
Then for some reason you don't struggle seeing places hundreds of miles further south dropping deep into subzero territory. Doesn't make sense, people said same about NYC the most absurd uhi on earth, and they went subzero in february.
Nyc went to subzero? That's not common at all. The more inland South probably has higher standard deviations.. the way the continent us shaped permits those areas a bit further west to more often get the deeper freezes.
I'd have to see it to believe it in Philadelphia. Probably the last time was Jan 1994.

It is not common here either! Only happened 3 times that we went below 0 in our entire nearly 140 year weather records. It has happened much more than 3 times in Philly and nyc. The only part of the inland south that will see much more deviation would be west of the app mountains such as tennessee.

Let's face it, it is a rather rare winter the Bermuda High protects the South. If that was the case their USDA zones wouldn't be as low as they are given the latitude. But year in and year out, excepting the oddball years like big Nino's 2016, Charleston almost always goes upper teens F and is zone 8b. If that Bermuda High was there every winter they would be 9b like in Western Europe or even higher.

Downtown Charleston is borderline zone 9b. Since 1980 their average coldest temp is 25.

I emailed the webmaster about it. Let's see if I get a response.
