Ostrich December

We’ve got changes on the models 72 hrs out. This one is 7 days. By Monday the Euro could have a foot of snow for Christmas and the GFS could have the scene from the day after tomorrow with tornadoes everywhere from severe weather. I will say for this to work you have to get the low to form down by Savannah or the Ga/FL border. That’ll slow the precip down and start forming that comma shaped snow on the back end that can drop several inches of snow in about a 6-8 hr time span. If that doesn’t happen then the upstate and those directly east of the mountains could get some very very back end snow showers as the precip exits. Those that live east of 77 really need it to slow down so that they do not warm into the 50’s ahead of the front. The upstate gets to the mid 40’s but quickly drops the temp as the front is sliding in during the morning hours and that’s much easier to work with to get snow.
 
Shouldn't you say "Western Carolinas"? Central NC and East always sweats coastals.That warm nose usually ruins the party for my neck of the woods. The Carolina Crusher was an exception, but even with that, places 30 - 40 miles NW of me got a foot more snow than I did.

It’s to soon to nail down specifics yet. Still it’s anyone’s or any models guess right now but we do have the ingredients.

The GFS is probably nipping a little too much eggnog. Anafront snow is really difficult east of the mountains.

As others have suggested, maybe we can get a postfrontal wave with the cold air already in place, but there isn't much support for that right now.

For now, I'll be pleased to have arctic air around for Christmas day.

Give me the Cold air, I've got a hose and will make my own snow for the kids.

You're welcome to walk over too!

Strictly speaking as of today from the GFS and its ensembles right now I think if you live in that first blue line (along and west the App Mountains/ North and west of 85 through Georgia and Alabama) you really got to like your chances to see some snow. Those frontal passages always work out well for those in Tennessee. It's once you get into the next 2 colors, any type of frontal passage of cold chasing moisture or clipper system do things generally don't work out. If you're directly east of the mountains and west of I77 I would really want to pay attention here. If we can get that LP to pop on the coast, then you would see a very heavy snow for 4-8 hours. The front passes through in the morning and the LP would help slow the moisture even more and allow for more CAA to drive into the region.Those in the purple color need a few more tweaks here. The first being you really want the front to speed up and not allow warm air out ahead of it to begin building in with mid morning and lunch time temperatures. Also if a coastal does form you don't want it pushing itself onto land and rather ride just offshore to avoid WAA. Now a lot is going to change here but those in northern Alabama, Northwestern and North Central Georgia, All of Tennessee, and WNC look really good as of today to potentially get some of the white stuff and I'm not talking about crack either.
