I wonder if the strong possibility of the La Niña breaking down within the next couple months has any affect on the southern jet starting to get cranking back up now. If so oh boy for the next 3-4 weeks.

Sometimes a phase 7 MJO/west pacific forcing can amp up the subtropical jet stream as well
That's quite a huge snowstorm from Upstate SC/Central NC and points north from there. Even Columbia gets a heavy backend snow . Move that 1048 H in Minnsota/Dakotas a bit futher south/east and this could've possibly been a historic snow event for a huge portion of South Carolina and even Georgia with more cold air involved for those areas . Overall I like the trend that we have seen on the Models so far.

I think the low pressure be a little closer to the coast.

12 degrees was as low as the temp went last night before the winds kicked in. Sat around 15-16 degrees until the sun came up and temps have shot to 42 already. With these temps and the heavy rain tonight the snow will be saying goodbye.
Gefs has raised AAM as @griteater mentioned, this slows down the pacific jet retraction even more, this has resulted in this change
note this was from yesterday at 12z, notice more ridging in the Aleutians and GOA as the gefs was faster with the NPAC ridge retrogression given the faster retraction
Now we have this, a stronger pacific jet way out in the PAC, and one slower to retract, this results in a extended stay with more Aleutian low/+PNA/-EPO, this change is a more clean look for the eastern US and has less fail potential

I saw lots of light snow events and even some bigger ones but a lot of light snow events on the GEFS all with potential to be bigger given better timing or amplification .. sheesh sheesh sheesh
Also a quick fun note to add with the GFS storm.. temperatures after the fact if you saw snow or ice temps remain at or below freezing for a few days after and even towards the end of the run highs only got to around 34-36 degrees and then below freezing at night … prolonged snow and ice on the ground for at least a week after the storm as well.. crazy

Those are some insane totals what a storm that would be
This might get interesting

Hi
Great Lakes low isn’t going to help!

here comes the plunge on the euro at the end of 10 days
That’s what I meant by workable. Lakes low may not be there next run. I still like the potential
