The thing that would mess it up for me would be the 850 MB temps don't cool enough before the bulk of the precip moves out, which would result in a giant sleet storm instead of snow. Arkansas will be probably having this problem for sure.
That initial band now showing up on the 12z NAM across Missouri/Kansas drops some decent amounts of snow. It's 850 MB front induced which currently sets up shop around Joplin this run while lifting slowly north.
EDIT: Same story with the 12z RGEM but the 850 front sets up farther south near the AR/MO border.
The long range still looks to feature a -EPO through mid-Feb so the cold air feed should be good to go. Time for the 00z models.
00z ICON has a massive ice storm followed by a massive snowstorm for my neck of the woods.
