There is a ton of low level moisture out there. This might be a good event tonight if the lift is decent. I've been getting snow all day, mostly little flurries since about 10am but still loads of low level moisture.

Sitting right at 2" when forecast by MRX .5 to 1". Still snowing.

Imby I bottomed out at 32 degrees at 9:24 pm then began warming from then till about an hour ago. About an hour ago I topped back out at 36 since then temp is falling again I believe in response to moisture in the dry air as my temp has fallen back to 33 and it's falling a tenth a degree or so every 5 minutes. Dew point is fluctuating back and forth at 25 & 26.

35/26 for me 67% humidity.

Radar starting to fill in quickly between Nashville and Crossville. I know there will be a period of virga but think it'll start sooner than forecast. Might need to move start times that MRX forecast an hour or more earlier. Virga already over me in the Great valley.

Yikes!!!

Looks like it is getting some GOM hookup to me.

That model depiction of ARW2 looks to me what makes the most sense for most of the valley of East Tennessee. I could buy 2-4" for most of the East Tennessee valley.

YES!!! It seems they always go NMB hardcore. It also seems NMB is often weighted in weird ways that seem to be way more conservative than actual verification. Great example was the deep south snow and our January snow. Both they seemed to align with NMB and in both cases it was way more conservative than actual verification.

Slight increase for most from their last map.

This is what I wonder if models are over doing downsloping and warm nose in combination with each other for a sort of double wammy for the East Tennessee Valley. Most modeling I've seen the push of warm air both warm nose and downsloping look a bit over done to me for this storm strength and track honestly I'm more worried about CAA and virga. Then you have models like the graf that have essentially been saying what warming of either type? Though I don't really know anything about the graf. Going to be an interesting morning tomorrow maybe some big busts in either direction.

If it means anything at all my point forecast has zero rain or mixing in now. All snow, and actual snow, not snow showers. Where yesterday and this morning included the weird snow then rain then snow again verbiage they often use. Also just reading MRX afternoon discussion which just came out about 15 minutes ago they mentioned advisory criteria area wide so they may pull the trigger on southern valley which would be smart considering Chattanooga has morning traffic too and schools and such and if they are "uncertain" as they mention over and over the wise thing to do is air on the side of caution.

Same here if the direction is more westerly I can actually get flow snow. WNW works for me but NW doesn't I think because with NW I'm in the shadow of Hinch Mountain the highest point in Cumberland County, I am due SE of it by about 10 miles. If the flow is more westerly that shadow shifts north of me just enough. Even NNW I tend to get some flow snow but not as good as WNW. Something really feels off to me about this storm. Start time for most will be during the coldest part of the day, my ground has been frozen the last few mornings and shaded areas have remained frozen solid even during the day. Last night I was forecast low of 29 but got to 25. Something just feels off about MRX forecast feels almost too cautious. At least for my area which is northern edge of the southern valley. My area also Sweetwater and Madisonville even Athens don't always fit "southern valley" forecasts like Chatty and Cleveland for instance.

Didn't the Euro have the system in January pretty anemic until just before go time? Am I remembering that wrong? Seems it was on the lower end of qpf and then started bumping QPF run after run up until go time. Maybe I'm mixing it up in my head with another storm. Though it was similar if I remember where GFS was more juiced and Euro less and the euro basically came around towards the GFS.

GFS is really sticking to its guns keeping the snow/rain line down just south of the Tennessee border. Hopefully it's sniffing out the CAA better and warm nose less of an issue.
