Looking back at modeling from 12z Wednesday. NAM had me with .32 precip, Euro .22, GFS .11, Canadian .10. NAM had me with 2.5 inches of snow ratio'd map with a 2 inch snow depth. Euro had me with 2 inches but doesn't have a depth map I can access. GFS/Canadian had me with a dusting. So it looks like the Euro/NAM were best for mby from 24 hours before the event started.

I'd like to see an event with temps around 26-29 instead of 32/33. BL temps always rule the roost. Even being at 32 vs 34 is huge. Maybe not in the cards for the rest of the season though. Today did make me appreciate just how hard it snowed in April 1987 and in a couple of other April events I had. My accumulation today came in two waves when very heavy snow fell at over an inch per hour rates. Less than that and it just snowed on top of the snow but it was melting from underneath at an equal or greater rate of the snow falling. I had a 3 inch event in April 1997 or 1998 when I got all 3 inches in 1.5 hours of silver dollars. April 1987 was basically 12 hours of silver dollars. We had that today but in shorter bursts. I had .30 QPF today. Looks like some areas around Knoxville towards Morristown had much more. Close to an inch in some places. I wish I could have given you guys my temps.

Yes, it came down pretty good for a few minutes. Looks like it's going to be the last shot and it looks like it's getting ragged as it leaves the Plateau area.

I have had a few heavy showers this evening. always nice to see.

Another shot of nice quarter sized flakes but its losing steam fast at this point.

Snow has backed off here.

Been rolling down here for the last hour. Crossing 2 inches. Seems like it's been forever to have big heavy flakes falling all day.

Thse 35dbz rates would be close to 1.75 inch per hour rates I believe.

Oak Ridge is reporting heavy snow with 1/4th mile vis, hope they are getting some accumulation out of it for our posters from that area. 1.75 inches here now, it's snowing around 3/4ths inch per hour rates on average but it's more 1.5 inch per hour then when it backs off it's compacting and melting from below about as fast as it can fall. I wish we'd managed a day in the 20s before this moved in instead of a day in the 50s.

The rates and flake size are very impressive when any enhancement rolls through. It looks like it's leaving West Tennessee, I assume in a few hours the transfer off the coast will take place and this will shut off pretty fast.

Snowing very heavily again. Vis between 1/4th and 1/2 mile. Around 1.5 inches so far.

Crossville reported heavy snow with 1/4th mile vis with the band that just moved through there, explains your situation Shocker! Enhanced area is about to move over me it looks like. Odd ob to me is rain and 34 in Middlesboro, Kentucky. Surprised they got any rain from this. I never saw anything but pure snow from the first flake. Not even drizzle or a sleet pellet. Just a few flurries and then goosefeathers.

wrong thread.

Close to an inch here. Steady quarter + sized flakes currently.

I-75 at MM 143. Around 2200 feet. Good thing no advisories were issued here and the sps was even dropped.

Ripping half dollars, this is basically 25 minutes worth.

Schools now cancelled here. Have the headache of running buses up the mountains here in the snow. I expect a parent apocalypse soon.

Came to town for some errands. Temp crashed here. Was 30 when I went into the bank.

Ground is turning white already. Happens fast with these big flakes.

Hard to see probably but quarter to half dollar sized flakes.

Finally moistened up. Its snowing decently now.

Looks like it shifted south just enough to knock me most of the way out of things. Good luck down south. Its gonna be an AN snow winter for Knoxville easily if the NAM verifies with what has already fallen plus this event.

The HRRR was giving your area several inches earlier. Good luck!

I don't know if it will be right with QPF in my area but the NAM is probably going to miss on changeover. At 10am it has snow on the Plateau and rain in the valley. The Valley appears to have mostly transitioned in areas getting QPF. Heck, I'm actually warmer than some of you way south of me at this point. The top down cooling was very efficient. If you guys get the NAM rates advertised I expect some egg on faces for some forecasters.

My humidity is tanking too. I was at 83 percent when the virga started now at 66 percent.
