Looks like the GRAF, which is a trash model. ?

Good grief... 0 degrees here at the end of the HRRR this is the middle of the day Thursday! ?
it’s late sister, the RPM model nailed the January 2018 storm though

Only thing I would have liked to finish it is an active southern jet, (and it lasting another couple weeks, lol). Everything has been northern stream dominate, and the timing is just all wrong right now it seems. This storm were tracking now looks way late and east. Maybe we get the western trend and amp it up even more last minute, but not sure it can back that far up.
Basically what the ICON has been showing

I really hope this overproduce in terms of snow!
Genuinely surprised they included ATL in the second graphic. I just got off work and got a notification about the Wind Chill Watch they issued for Thu night into Christmas Eve. Wind chills across N. GA ranging from -10 to -20 below zero. That’s gonna be brutal.

The wave dropping down after the Arctic blast has a decent look to it now on the modeling, but an issue I see is this…what we’d like to see as the wave drops down is a jet streak behind it to drive energy and lift into the base of the trough in the left exit region of the jet streak (a key feature in the Jan 2003 setup for example). With this one, the jet streak is weakening, and thus, the dynamics aren’t there for it to really explode like it needs to in the base of the trough. On the loop, it looks like the increasing jet flow from the west is breaking down our digging trough via an anti-cyclonic wave break (the top part of the ridge behind it is toppling over and the whole jet dynamics are weakening). I will continue to watch of course, but I suspect this isn’t something that is going to suddenly improve on the modeling. Of course, now that I state this, the happy hour GFS will assuredly go bonkers with it and look good

Yes, I look everywhere for nuggets of encouragement. I see Japan likes the super-clipper idea too.

Man, this is something else...
I wonder when the last time was that New Orleans was below freezing in the middle of the afternoonMan, this is something else...
Guessing that freak upper level low snowstorm back in 2008 maybe?
