JKL finally updated their AFD. Say to expect heavier totals than first thought, so those of us who live near the  KY border in Tennessee or SWVa can probably expect similar weather.

The cold front should continue to slowly sag south across the area
with the slow movement of the boundary and the post frontal band of
snow slow due to the still digging shortwave. However, this shortwave
should begin moving more to the east through this morning with the
through trending toward more neutral. This should lead to the
boundary continuing to slowly move east with a surface wave or two
likely moving along it while deeper moisture persist much of the day
across East KY lingering into the evening in the southeast. Also, a
jet steak moving through the OH Valley to northeast should put much
of the region in deeper lift when combined with the lift from the
approaching shortwave. The forecast soundings trend closer to
becoming isothermal nearer to -10C this morning and into the
afternoon across the south and southeast. Thus, the combination of
this, the deeper lift and substantial omega for a while in the DGZ
will probably lead to higher snow to liquid ratios from later this
morning into this evening and a bit more snow than the previous
forecast. As the shortwave starts to move east and approach, the
steadier moderate to at times heavy snow should continue pushing
south and east, possibly not arriving at the VA border until as late
as 10 AM. The steadier snow should end this morning near I-64 and
north though the steadier snow will persist longer in the southeast,
especially near to the VA border.

Quick question: for hours, the precip band was barely moving...stuck in a more SW -> NE progression, but now it seems to be moving more east and picking up speed? Was hoping these dbz’s would last longer; not sure why they rush once they get south of LBL and east of the TN River. 

the upper trough is beginning to pivot.  Yes, it will cause the band to move but also it is the pivoting that helps bring up moisture

When was the last time that the entire states of TN, AL, MS, and LA were under winter weather advisories and or Storm warnings simultaneously? I don’t know. I can’t remember anytime. And most of AR, KY, part of GA, NC, and SC, VA, and even FL are as well. Regardless of how much falls in any one given area, this is about as large of an area of the south that I can remember seeing covered. Image below is from Pivotal Weather

Some of the weaker model runs began showing the precip field to deteriorate about now, or in the next hour or two, looks as robust as ever to me.

If the band of snow can hold together we should get a good snow let's hope it don't fall apart. To me it looks to be growing on radar anyone else see that.

I’m leaving Cleveland now headed toward Dayton, very thick overcast with haze to the West, be in Dayton for about an hour or so then off to Spring City!

I noticed that the band seemed to be widening some across N MS and W TN, but in SE AR it was fading some. May just be normal ebb and flow, but it does seem to look pretty good right now.
