18z GFS with not a bit of moisture reaching Tennessee.

I'm not too worried about it, because for one, the other models don't agree with the GFS. The other thing is that this system isn't on land yet. These models runs today and the past several days need to be taken with a huge grain of salt.

I agree the land based stations will help out alot once onshore.
 
GFS 00z some of the plateau and northern counties might see a little snow Thursday night into Friday morning...light probably dusting to 1/2 inch

0z GFS was still too far south, however, it did slow down a little and slightly shifted north (about 25 miles north of the 18z run).
 
Winter Storm Helena...TWC is calling for area of ice before it turns to snow below Tennessee ..bad news for me I have to head down to Alabama on Saturday..right now it looks like we will just be cold and dry on Saturday in ET...further east and south will be better chance of snow. Could still change though.

Wvlt David Aldrich just said 2 to 4 inches here with 5+ in the mountains.

2+ in Knoxville with the 4in up towards Morristown and Kingsport.
 
Wow that would be awesome..not seeing that anywhere else though

That's because David is essentially dismissing the GFS. On his Facebook live video, he explained that due to the very wild swings of the GFS runs lately (going from a foot of snow to flurries to a half inch in a 2 day span), he's not liking the model for this system. He's leaning towards a blend of the Euro and Canadian.
 
Something not to overlook is the Thursday night wave of snow. The GFS and Euro are both showing it and have been for a few days. Could make for interesting travel Friday morning.

I'm monitoring it. I'm at work. I think it will be a light snow fall. Maybe VK can play with the Ratios. I don't know how heavy it will be coming down as I have been following Saturday's storm.

...Winter Weather Expected Across The Area Thursday Evening
Through Friday...

An arctic airmass will move into the area Thursday evening ushering
in some accumulating snow and much colder temperatures.

Starting Thursday evening and ending Friday night, areas of
southwest Virginia and higher elevations of northeast Tennessee
could expect to see snowfall accumulations of 1 to 3 inches.
Elsewhere across the area north of I-40 totals of 1-2 inches are
possible while southeast Tennessee and southwest North Carolina
will likely see only a dusting to 1 inch of snow.

Greatest impacts to travel will be in southwest Virginia and
northeast Tennessee where temperatures will barely climb to
freezing on Friday. This may lead to some slick spots and travel
hazards particularly on secondary and untreated roads, bridges and
overpasses. Throughout the area, please use caution when traveling
Thursday night and Friday. Slow down and allow yourself extra time
to reach your destination.
