Carvers Gap Posted March 12, 2018 Share Posted March 12, 2018 It is 41 in Kingsport with a windchill of 31. Wind chills are forecast tonight to be in the upper teens to lower 20s. Snow advisories are still posted for mountain communities. Still feels like winter, but spring temps are back in the forecast for this weekend.

Carvers Gap Posted March 12, 2018 Author Share Posted March 12, 2018 I should add that the 12z EPS now has the trough back in the East for days 10-15 w warmth along the Gulf. Link to comment Share on other sites More sharing options...
Holston_River_Rambler Posted March 17, 2018 Share Posted March 17, 2018 Randomly was in Bristol/ Abingdon area today and managed to get a photo of a storm to my north in the distance as it went severe at approx. 330 - 4 PM (photo 1). On my way back to Knoxville another smaller storm developed right over downtown Knoxville and I was able to get a photo of it as well! (630ish) (photo 2).

Holston_River_Rambler Posted March 20, 2018 Share Posted March 20, 2018 Really interesting to see the boundary setting up between Abingdon and Blacksburg. I've always wondered why, if there is cold air damming going on, if it can make it to Abingdon, why it doesn't just keep draining down I-81? It's heavier and denser, right? Maybe it's not CAD, but the wind barbs in the included image seem to indicate a NE wind. I guess the warm air advection just beats out CAD after a certain point... Pretty easy to see too where the rain snow line is going to set up for those folks as the heavy precip develops and moves in. Link to comment Share on other sites More sharing options...
John1122 Posted March 21, 2018 Share Posted March 21, 2018 Snow has begun here with a dusting so far, not the best photos, I had to use my headlights and resize them to be able to upload them. Link to comment Share on other sites More sharing options...
John1122 Posted March 21, 2018 Share Posted March 21, 2018 32 with moderate snow. Nickel sized flakes filling the air, fogged in look. Around 1/2 inch accumulated so far. Link to comment Share on other sites More sharing options...

Pretty easy to see too where the rain snow line is going to set up for those folks as the heavy precip develops and moves in. Tonight has been a perfect example of the phenomenon just as it was last week. For those in the New River Valley when it comes to winter weather this occurrence is like CAD in the piedmont only elevated with even more favorable conditions. It also marks where I consider the NE edge of our forum it is where the primary spine of the Appalachians transitions from the Blue Ridge to the Allegheny as the dominant range. To re-iterate it has been a long stubborn fall in temperatures to the west of it. I am currently at 37 and have seen a few melting flakes finally begin to fall.

John1122 Posted March 21, 2018 Share Posted March 21, 2018 Snow+ still. If not for the warm ground I feel like this would have been a 3-4 inch event. Link to comment Share on other sites More sharing options...
BlunderStorm Posted March 21, 2018 Share Posted March 21, 2018 It is now 34 the transition to snow is mostly complete with light snow but big flakes. The next hurdle is to get it to stick. Link to comment Share on other sites More sharing options...
BlunderStorm Posted March 21, 2018 Share Posted March 21, 2018 The temperature is at freezing snow is beginning to stick to the grass so I can record a trace so far. Link to comment Share on other sites More sharing options...
John1122 Posted March 21, 2018 Share Posted March 21, 2018 Passing over an inch here. Still moderate snow with about 1/2 mile visability. Link to comment Share on other sites More sharing options...
BlunderStorm Posted March 21, 2018 Share Posted March 21, 2018 I think I will retire for the night a quarter inch of snow has accumulated thus far as my final observation of the night. The temperature remains a steady 32 with light snowfall. A burst of moderate/heavy snow at this point would likely turn the roads white for a short time. It was enjoyable to observe and I guess my goal for the night was achieved in spite of the temperature woes. Link to comment Share on other sites More sharing options...
John1122 Posted March 21, 2018 Share Posted March 21, 2018 I-75 from the Campbell/Anderson line to the Kentucky border is now reported as hazardous with snow and ice on the roadway. Moderate snow continues to fall here and should for the next 4-6 hours minimum by looking at the radar. Have about 3 hours until the sun comes up and probably ends most accumulation. Even with decent rates and freezing temps there is bottom up melting due to ground temps. Link to comment Share on other sites More sharing options...
John1122 Posted March 21, 2018 Share Posted March 21, 2018 Currently in the heaviest snow of the night, visibility is probably between 1/4th and 1/2 mile. Nickel to quarter sized flakes, air is absolutely full of them. The trees are going to look awesome by sun up. Link to comment Share on other sites More sharing options...
Jed33 Posted March 21, 2018 Share Posted March 21, 2018 Another Wednesday another accumulation, albeit this time I’m surprised. I got a message from the school that they were on a 2hr delay, so I looked out, and to my surprise, we have about 1/2in on the picnic table and grass. The temp is 31. MRX mentions in this morning’s AFD that the rates have caused the temps to fall lower than previously expected. That would make sense I guess. Now the trick will be to see how much more could possibly accumulate. Link to comment Share on other sites More sharing options...
John1122 Posted March 21, 2018 Share Posted March 21, 2018 Closing in on 2 inches with moderate snow still falling. This is going to be my biggest event of the season and put me over 10 inches on the season. Something I'd have never believed on March 1st.

Holston_River_Rambler Posted March 21, 2018 Share Posted March 21, 2018 We've had some nice snow near downtown Knoxville, but that extra urban heat definitely takes its toll on anything's ability to stick. Not really disappointed for myself, but in fact happy that many of you are getting snow! If anyone wants to see something unique, go to http://weather.cod.edu/satrad/nexrad/index.php?type=MRX-N0Q-1-200 this AM before the data expires and watch across north Knox county. There some weird mesoscale band that seems to set up after the flow turns as the front comes through yesterday afternoon and runs W to E from maybe Powell toward House Mountain. I've included an image that shows a piece of it and what to look for, but it really isn't evident until you watch the 200 image loop a couple of times. It seems to only last as long as the precip is flowing from W to E. Would be interested to hear any thoughts on this... Link to comment Share on other sites More sharing options...

Kentucky Posted March 21, 2018 Share Posted March 21, 2018 hoping the backside holds together, about 1/2 inch on the grass here in Corbin. Update: And like the parting of the seas, I have snow to north and south... Link to comment Share on other sites More sharing options...

nrgjeff Posted March 21, 2018 Share Posted March 21, 2018 My guess is that air flowing parallel to those two mountains converges on the lee/back side. Low level convergence helps precip. Similar process can happen with a peninsula sticking out into water with an onshore (sea)breeze. Air converges and showers pop on the penninsula. A difference is the mountain example today also involves wake processes. Good meso/micro scale observation for all to remember.

1234snow Posted March 21, 2018 Share Posted March 21, 2018 Had a dusting overnight that partially melted this morning but now moderate snow has moved back in over the past 30 minutes. Probably have an inch now and the roads are starting to get covered actually. Wind is howling and the flakes are tiny tiny. Not pellets but very tiny little balls of snow. Temp is 31.

John1122 Posted March 21, 2018 Share Posted March 21, 2018 I'm right at 3.5 inches. I'll be surprised if I can add any accumation during the day. It's melting from below and and compacting quickly. That's easily double what I expected and is the biggest event of the season for me. Link to comment Share on other sites More sharing options...
Kentucky Posted March 21, 2018 Share Posted March 21, 2018 Surprising for me too, I'd say maybe an inch on the grass. Link to comment Share on other sites More sharing options...

BlunderStorm Posted March 21, 2018 Share Posted March 21, 2018 The HRRR looks to be right. I have got about 3/4ths of an inch on the ground. The wet snow certainly makes it seem more than that though with how well it stuck to the trees. I may send a picture soon. Another 1/4th of an inch and I can call it an inch even.
