Also, ever wondered how frequently your location was warmer than another? You can answer that too on this site.

Atlanta vs Birmingham. Atlanta is warmer only about a third of the time

Much of the reason for that is that Atlanta is 400 feet higher. Otherwise, it would be a lot more than 1/3 of the time because KATL is so much warmer than surrounding areas for lows on radiational cooling nights. They are the anti-Gainesville as far as radiation is concerned.

I would have never thought elevation versus amount of asphalt/people/cars.

Greensboro is warmer than Raleigh only ~15% of the time, w/ this percentage varying according to the season.

Last one, I promise.
Daily snow depth analyses going back to 1893.

I’m saying that what’s keeping KATL from being warmer than Birmingham (by one degree) more than 1/3 of the time is that KATL is 400 feet higher. That can cool things off a couple of degrees vs if it were the same elevation as Birmingham.

Plus wedges are always stronger temp wise in ATL compared to bham.

No wonder March of 1960 was so cold and snowy. Look at the expansive snow cover to our north and north-east. Didn't realize that there was that much snow on the ground up there. CAO's didn't have a chance to modify before reaching us.

March 1960 looks like ?

Yeah 1959-60 really turned it on in late February right on thru mid March.

You can see it for yourselves here:

Isn't it bad if everything north is warm?
Click to expand...

The above normal anomalies to our north are a result of mild, Pacific air flooding south-central Canada. Source regions for cold air in the arctic become warm(er) when the initial air mass moves out & is usually replaced by a warmer one that's usually from the south (simply because near the north pole, almost any wind (and thus advection of air masses) is from the south which is a warm wind (minus when an air mass is being transported from Siberia)). The fact that these warmer anomalies are closer to us is the only qualm with this, however even well above normal in the northern US & south-central Canada at this time of the year is cold enough to produce snow in the upper south if those air masses get advected our way

If I see one more “strat PV is gonna end our winter” post on Twitter one more time, ima go insane
Click to expand...

The same people were saying the PV was strong and on the other side of the hemisphere, so it won’t be cold...little did they know there was a small disruption and elongation which has brought cold temperatures this week. Literally these same people though this week would torch.

There’s a LOT we don’t know about PV influences over North America. A lot we have yet to figure out. These “hot takes” of 300+ hour 10hpa GEFS progs are a joke.

I’ve seen 384 hour Strat PV maps from the GFS being taken seriously, lol
 
Jon said:
The day he was talking about the TPV and calling it the SPV or vice versa is when I stopped taking that account seriously. He ends up being “right” because other drivers of the warm pattern are doing his work.

Not surprisingly, Bamwx unfollowed me after I called them out on their bs regarding the SPV.

Absolutely mystifies me how certain people with no meteorology degrees can start a website, a couple computer monitors, and a Twitter can be a "million dollar business."

Need monitors ? I’ve got 6 43 inch TVs I bought at an auction brand new in the box . We could go to toe with the best of them . We have crazy ass smart Mets on here and people that are not Mets that would run circles around some of the BS Twitter “ companies “

Let me contact some of my MLB associates and get us on with the Atlanta Braves,
let me call some stock websites and get some press release type articles speaking of us in good light,
and let me install Wordpress and install a payment gateway.

Then I'll be ready to take a selfie by 3 computer monitors with SimuAWIPS loaded in the background. BRB

@chipper_jones -- i need your assistance good sir.

Here’s early Friday looks interesting. I’ve also been looking in the CAD areas of NC/SC for Friday morning with weather models NCEP model blends and temps look to be around 20-30 at this systems onset. This system could be a bit of a shock if temps were to verify that low.

Each model run of the gfs has been increasing the chance for onset snow for MS/AL. Euro also agrees with a light painting in MS

GFS slightly less enthused with the NW flow for the mountains behind the front next weekend..too early to call it, but for now I’m out..

edit: what do you even call that? wraparound? NW flow? I feel like there’s some gray area there
