  1. 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.
  2. Snow has taped off to light here. Right at 7 inches fell using the wipe method. Approximately 6 inches max depth.
  3. I see the OB is snow and blowing snow in Chattanooga, temp 18. How often do you guys see that?
  4. 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/
  5. 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.
  6. Moderate snow, vis around 1/2 mile. 6.5 to 7 inches. It's gotten hard to measure due to wind.
  7. I'm down to 14 degrees and it's back to absolutely pouring down again. Vis around 1/4th mile. The radar doesn't even look impressive but even seeing returns at all on the Plateau when the DGZ is almost to the surface, is impressive.
  8. The HRRR snow expansion down the valley and along the foothills is happening before our eyes in real time.
  9. At these temps the pre-treatment is way less effective. Could the sounds have been a wreck?
  10. It's been crazy how it's just sat in place. The bands, as you guys are now getting to see, are darn fun. That's the best and worst part about ULLs. At times their banding may give an area 6 inches, and 20 miles away that area may only get an inch.
  11. That's ripping. I can never get good photos of snow falling!
  12. I have a spot where I measure and a spot that I clean off every three hours to measure. That will give you a good idea of your rates. And in cases where the snow is wetter than this, it will give you a better measurement of how much snow actually fell since you won't have as much compaction.
  13. I'm down to about 1/4th inch per hour now, hopefully it can keep up here until 9am at least. That would get me another inch and a half.
  14. I think the 10+ projections from models that way will probably verify. The ratios are incredible so it will really stack up. I can't account for micro climates there because I don't know them like the folks who live there. But I did see that this was overperforming around Bristol at least. And Tri had 5 inches 2 hours ago.
