Where has Jeff been? He has been awfully quiet with the potential of Chatt getting some snow.

GFS absolutely clobbers the southern valley from Chatt to Lenoir City.

Wow, looking at it more closely, it drops 8 inches in 3 hours from the 18 to 21 hour. Almost 3" an hour rates. That would definitely overcome the ground temps quickly!

I approve the RGEM's output. Still can't post screenshots but it has almost 10 inches in Knoxville when ratio'd.

Canadian just rocked the plateau. 12"+ in some spots.

Won't let me post pics again, but 03z RAP was pretty robust for KNX and the plateau.

Surprisingly, looks like the GEFS mean came done slightly for almost everyone from 18z.

Anyone else notice that glob of pink that starts in Arkansas and travels all the way up to Pennsylvania? Looked like a long track super-cell of snowmaggeden under that thing.

Ratio'd GFS

Knoxville is the coldest place on the entire map.

This looks like a reasonable run to me. Plateau & Mountains get plastered and a general 2-4 inches up through the valley.

Is it just me, or is the changeover happening quicker on the NAM? Comparing run to run the snow line keeps trending east quicker.

I think it is to. The sleet/mix line is noticeably thinner on this run compared to the 18z.

Low pressure isn't as amped as the 18z run, but still looks to be a good track.

Live look at all of us waiting on the NAM to finish.

Looking at KNX, the mean held steady, but much more agreement between 5-7 inches and the lowest member is 1.17.

I feel like a broken record, but the 21z SREF went up again for the plateau & SE KY. Slight uptick for KNX it appears.

WBIR is showing what I thought MRX would show earlier.

GEFS Mean. Pretty big increase along SE KY/Western Virginia

That dark red streak might require a blizzard warning in northern mid-TN and SE KY

Ratio'd totals

I'll take this look all day long.

I'm actually shocked!

I think NAM is going to be juiced. Already a 997 low in central Alabama at 36

MRX is going to say 1-3 for the valley with locally heavier amounts and issue a WWA and call it a day. I'd be surprised if they issue anything more than that today. They might even wait and let the night crew issue it.
