Its not so much that it loses it, it's that the low is further north than the GFS so the precip is too. It did move more to the south and west vs 12z with the slight step towards the GFS.
That clipper on the euro is almost what the gfs showed the other day. It thumps northern middle Tn and southern middle Kentucky where those convective looking snow showers are.
The Euro is maybe a little better with the first wave than 12z so far. Nothing like the GFS with that Lee side low it pops and bombs us, at least not yet. Still rolling.
Euro AI has lost it as well on today's runs, including 0z here. I hope it's wrong but with only the GFS and ICON on board, this is very unlikely to be a big event.
Every other model is just some N stream snow showers. I'll be surprised if the Euro Op isn't the same.
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.
