Definitely better than the GFS

Compared to the GFS

In all honesty, this setup ain’t really warming up at the SFC, just aloft, this looks like a pretty classic trend to a dominant Miller B setup, vs a flat/snow setup View attachment 103827

Correct me if I am wrong, but doesn't our area tend to do better with Miller B setups and opposed to Miller A. Flat/Snow setups? Aka Feb 2014.
 
Ehhh. Canadian is used for CAD out of the globals as it gets a better feel for it due to its cold bias. This is a legit CAD that we probably haven't seen since Feb 2014 so it's pretty realistic in my opinion.
Agreed… and it has support on it from its ensembles and GFS/GEFS

Agree, you could already see the GFS came in with stronger HP and colder surface temps, transferring energy off the coast, problem I have with that run it then drives it straight north up I-95. I have my doubts about that track but we will see, sure seems we have a significant Miller B wintry threat evolving
 
The 12z GFS,Can, Ukmet are all almost identical on the 500 vort map at hr 96. By hour 108 The ukmet goes to the GOM shoreline and the 12zgfs stays up in northern MS. Cant figure out why each does what it does. We all prefer the dive down to the GOM and not a northern AL/MS path.

Eitheir way you slice the pie its gonna be all frozen in Triad NC with surface temps 20-22 whole event. That we can be very confident of.

Not often you get a Miller B with a +PNA, the H5 pattern for this possible Miller B is pretty different then the Miller B composite

Unfortunately though if memory serves me correct, the UK has a overamping tendency and a southern track bias.

Maybe the Euro will get onboard.
 
In all honesty wait a couple of more days then use a blend of the GFS and ECMWF and you'll have a pretty good idea on the final solution. Instead of these run to run differences. :)
 
For those who dont remember February 2014(especially in the charlotte area):

I was in Fort Mill at the time. We started as heavy snow on the first morning around 23 or 24. We ended up getting about half a foot to eight inches before we changed to sleet and then to freezing rain. We changed back to snow on the way out the next morning.

It's still one of the best storms of my life and it had three different transitions.

I absolutely loved that storm… the sleet and ice we got during the middle of it really helped to keep the ground covered for a number of days afterwards despite the February sun angle and a fairly quick warm up after the storm. A storm similar to that right now at peak climo and below average temperatures after the storm could really stay on the ground for awhile.
 
One thing to keep in mind as this appears to be turning into a Miller B or Hybrid A/B set up is that often times you can get an area of overrunning snow that breaks out well ahead of the main system and the models often don’t pick up on it until inside 12 hours. The February 2014 storm was a great example of that here southern and eastern areas of CLT metro back into the eastern Upstate… the snow started about 6 hours ahead of forecast and got heavy very quickly
 
Euro has the first wave that develops our 50/50 Low digging further SW in the short range. That is really telling for what we can expect our storm to potentially do as well.

Edit: It closes off right off the coast of NC which really helps for further development of the 50/50. Also the 850's are colder so far.

And one of the biggest disappointments in my lifetime for most of the upstate. 8-14 inches predicted by local mets the morning of and 3 inches of slop for me.
 
Brad is a solid dude, and it's encouraging that he's getting more confident in at least some type of winter weather considering how conservative( and rightfully so) he is.
Good video as always from Brad. I wonder if he’ll be back from his vacation by the weekend. He’s such a weenie too, he’ll hate not being in town for a big storm
 
Speaking of NW trend, the system on day 3 has moved waaay west. Not sure if good or bad, it could bring in more confluence and cold air for our storm
