The link works but I couldn't get anything done on the actual site. -

Some social media response to that terrible map. This is why snowfall averages are off and it effects weather model performance. -

It seems to match closer to their forecast map. -

Here's a surprise. Map is way off here. I also feel like Holston got more than 1/10th of an inch as well. -
It may hold down surface temps slightly but in the atmosphere is where the temps will cause it to rain.

I don't know if winter will be over after this upcoming warm up, but it's unlikely to return to anything remotely like we've had this week with the cold and ice/snow being able to stick around. The Euro doesn't even go below freezing from the 9th to the 16th here. It's head faked warm ups a couple times this year already, but often when the Pacific breaks down in February and a big warm up hits, it lasts so long that we are in March before it relents.

Steady pixie snow here as well. Picked up about 1/4th inch in the last two hours. -

I feel you there. They'll put out a wildly inaccurate map at some point. -

Light snow here. Future radar shows the lake moisture snow arriving overnight. No idea if it actually will or not. -

I remember that. Seems like a strong NNW flow band set up and ran right down 75 for extra snow down that way. -

Lafollette to Caryville got 4 to 5 inches from what I could tell when I went out earlier. I drove right by the spot on the mrx map that shows 1.5 inches and there was at least 4 to 4.5 there. -

Final measurement before dark. Settling/compacting basically offset any snow that fell today so it didn't get any deeper. But on the protected snow board I added 3/4ths inch today. -

I think it will rotate east as the low moves east. The NAM from 84 hours out showed this for 7pm today, as crazy as that is. Showed the Plateau into middle TN with snow showers and a break between that snow and snow along the mountains. -

As dark has approached thicker clouds rolled back in and I have steady dimes and nickels falling. -

I definitely beat 1/2 inch. I did see that MRX is going to claim my area got 1.5 inches per a "trained spotter". I saw multiple people from this area (Campbell County) reporting 4 to 6 inches to them but none of those reports showed up yet. -

I don't know if the band of GL moisture will rotate east or not, but we could get some decent showers from it since it's so cold, if it does. -

There's so little water content, any sun will zap layers quickly, even if it's frigid. -

I hope you're all using the clean and measure method. The amount of compaction with this one surprised me. It's fluffy and light and I guess easily compacts. That's why some of you may seem to be accumulating more slowly than you think today. I actually thought it had stopped snowing here, but had to look something dark colored (vehicle) to see that some of the smallest snowflakes I've ever seen were falling. I get a few dime to nickel sized flakes then back to micro flakes. -

Snow has taped off to light here. Right at 7 inches fell using the wipe method. Approximately 6 inches max depth. -

This live cam from down in town shows how ineffective salt is in this weather. This is Hwy 25w/63. TDOT had heavily pretreated and spread salt through the night. https://www.resortcams.com/webcams/downtown-lafollette-tn/ -

I was surprised to find almost an inch of compaction in one of my measuring spots from last night. I didn't take any measurement at all from 4:30 am to 8am. I was at 5.5 inches in that spot, from 4:30 to 8 my cleaned off spot accumulated .75 inches, but the measuring spot actually went down to 5.25 inches. -

Moderate snow, vis around 1/2 mile. 6.5 to 7 inches. It's gotten hard to measure due to wind.
