Cotton7204 Posted December 25, 2020 Share Posted December 25, 2020 Got right at 3 inches in Clintwood, Va, Sort of hit and miss in around here, Ive heard someone in big stone gap have 6 inches, and 5 inches in southern Dickenson county. 12 Link to comment Share on other sites More sharing options...

PowellVolz Posted December 25, 2020 Share Posted December 25, 2020 The DGZ is probably below 700mb at this point. Ok. I didn’t know the DGZ would fluctuate in elevation. Interesting, looks like I found something to read tonight. . Link to comment Share on other sites More sharing options...
John1122 Posted December 25, 2020 Author Share Posted December 25, 2020 Has anyone been able to get the new dial pol precip type radar on the NWS site to work? I still have steady light to moderate snow falling. MRX posted no further accumulations the rest of the night a few minutes ago. I'm currently accumulating right now. 1 Link to comment Share on other sites More sharing options...

Interesting, looks like I found something to read tonight. . The DGZ is where the atmosphere reaches -10 to -20c. If there's high RH in that sector snow flakes will form. That's why snow can fall from below radar beams with the upper levels are really cold. You can even go out when it's below 0 at the surface at times and flakes will seem to form out of a clear blue sky. That's because the DGZ is very low at that point and any moisture in the air turns to snow flakes. 3 Link to comment Share on other sites More sharing options...

Math/Met Posted December 25, 2020 Share Posted December 25, 2020 Good post by John about the DGZ. You can see the effects of the lowering DGZ starting to show up on radar. This allows for some of the low level instability and lift to extend into the DGZ, and helps to aid these bands. 5 Link to comment Share on other sites More sharing options...
dwagner88 Posted December 25, 2020 Share Posted December 25, 2020 HTX radar looks very healthy. Plenty of streamers even down here. Nothing falling at the moment, but I can’t complain about the look. Definitely not a typical NW flow look. 4 Link to comment Share on other sites More sharing options...
McMinnWx Posted December 25, 2020 Share Posted December 25, 2020 Just a decent band come over my house. 2 Link to comment Share on other sites More sharing options...
Carvers Gap Posted December 25, 2020 Share Posted December 25, 2020 Running just north of 4" of snow. With so much blowing earlier, tough to find a spot to measure that wasn't in the lee of a big tree. Things have settled down now. Just waiting for snow showers to fire, and put a top on the new snow. Great day! Great to hear all of the observations from everyone. 9 Link to comment Share on other sites More sharing options...
Vol Man Posted December 25, 2020 Share Posted December 25, 2020 About 3-1/2 inches right now...intensity slacked up quite a bit right now...East Kingsport 1 Link to comment Share on other sites More sharing options...
John1122 Posted December 25, 2020 Author Share Posted December 25, 2020 I've added almost a half an inch of fluff in this band that's been streaming overhead for about 40 minutes now. Its ultra high ratio stuff, probably close to 20:1 right now. Temp is 22, reminds me of upslope. 4 Link to comment Share on other sites More sharing options...
John1122 Posted December 25, 2020 Author Share Posted December 25, 2020 Accuweather minute cast pretty much nailed the end time of the synoptic snow here earlier this evening. Gonna monitor the next hour and see if it changes or if this band overhead moves on before the 69 minutes are up. Lafollette is a bit SE of me, so I'll shave 10 minutes off the time and see where that gets me. 1 Link to comment Share on other sites More sharing options...

Blue Ridge Posted December 25, 2020 Share Posted December 25, 2020 Closing in on 5” here. Lighter band now, but much smaller flakes. . 3 Link to comment Share on other sites More sharing options...
Math/Met Posted December 25, 2020 Share Posted December 25, 2020 There was about 4 inches on the picnic table the last time I measured. I'm trying to remember if Greene County ever had a decent mountain wave event (75mph gusts this morning) and then had this much snow in the same day. Interesting day for sure. 7 Link to comment Share on other sites More sharing options...
PowellVolz Posted December 25, 2020 Share Posted December 25, 2020 Perfect example of what these streamers will do if you get under one. These 2 pictures from TDOT are about 2 miles apart just east of downtown Knoxville. . 6 Link to comment Share on other sites More sharing options...
