The UKIE is in the Canadian camp. Not much cooking there except some NW flow snow showers and cold. It's not the best place to be on team ICON/GFS vs the other models.
The GFS would be just about perfect for most of us if it came to pass. First wave buries the east side, the second is nice 3-5 inches for the west and still added 1-2 inches over the rest of the state.
ICON hits from Eastern Rim and points east, especially north of 40, on the 15th. Another round headed for Western areas by the 16th or so, with snow breaking out in Arkansas.
Euro AI is just a printer repeat of it's prior runs. Too warm unfortunately west of the eastern Highland Rim/Murfreesboro area but snows over the eastern half.
The EURO has some odd convective snow showers scattered around that gives areas that get them a couple inches. Then has a miller A second system that has the heaviest snow in the East but some snow back to just west of Nashville. As Jax notes, very much for entertainment purposes here but whatever the models are seeing the last 24 hours seems to be universally producing something.
These storms are highly unlikely to play out as modeled, but the multiple windows Carver's has spoken of are definitely in play.
The Canadian would be 1985esque with heavy snow state wide and well below zero cold.
The Canadian is still snowing over the eastern half of the state at the end with temps in the single digits across the state. It's so cold the ratios are insane. Almost 20:1 in parts of the area.
The Euro AI has the same footprint but much drier. I've noticed the Euro Ai last year was always the driest model, and the AI GFS is also drier than the OP models.
The Euro has a slider/miller A going inside D10. Nice hit for Eastern areas and Western NC. The mountains get buried with 12+ 3-6 or so Eastern Highland rim to the foothills.
If that low track was 100 miles south on the GFS, that heavy snow would have been 100 miles south too. It was a west to east gulf low but about 75-100 miles north of our best tracks.
