can see the flow starting to pull more toward our classic NW direction as the ULL is sweeping through. Full on NW regime will begin over the next few hours!

We moved and are now right above 2k . yeah we do ok here. I can usually score 40-50% of what the top peaks around me get. Depends alot on the exact flow here too I think NNW is best since the path from JC down to Erwin is pretty clear. I've seen moisture pile up in the valley from that way. Helps pad the annual averages atleast. Erwin proper is always in a snow hole from high peaks all around it. We are out of Erwin and up the mountain just enough to not live in the mountain shadows 24/7

Radar is looking great over that way. 20-25dbz is pretty good in this setup. Temp down to 30.9. Super small flakes but a billion of them. Roads white. My 2wd truck cringes at driving to work in a second.

Going to be a slow dance but you can see it slowly coming together. We will get that upper level energy diving and consolidating tmrw which will pivot and rotate that moisture through TN. Great tap from the Great Lakes. This certainly looks like it can produce the totals we are seeing on models.

In layman’s terms it’s pretty much explained in its title. “NorthWest Snow” low level winds from the northwest pass up and over the mountains. Those NW facing slopes get enhanced lift during these times and that’s why they can get a ton of snow. Wind from the northwest hits the mountains and is forced up. Creating lift and snow along those areas. It can be feast or famine as the NW slopes get dumped on but slopes not facing the exact perfect way get much less snow. here are a couple links. One has pictures which I like. The other is pretty In depth. But a good read! Google is my best friend for terms I don’t know lol. https://www.weather.gov/media/gsp/localdat/NWFS_discussion_group/Additional Links/Northwest Flow Snow_Dec05.pdf http://appstate.edu/~perrylb/Research/Publications/Misc/Perry_2006_Diss.pdf

It’s a very cool depiction of those up-slope enhancements. The first thing I noticed was just how hard that down-slope side actually is in Western NC. not sure how strong 10+ (bars per second?) is but considering the velocity up by our main low pressure is abt the same I’d say that must be some pretty strong lift.

Pics/Videos/Stories from past weather systems in the region
fountainguy97 replied to Shocker0's topic in Tennessee Valley
Just curious. What are some of the biggest NWFS events in this areas history? Was the hurricane sandy snowfall considered NWFS? -
I would say the same thing. Will probably take a complete model consensus tonight to get them to sway. Past couple of events have struggled to live up to expectations across most of TN.

Insane haha the amount of energy aloft is very high. I’ve only been here for two winters but this is by far the most vigorous NW flow I’ve seen predicted. the DGZ zone (-10 to -17) starts at 850mb and there is ample moisture and upslope to produce a very significant event. I wouldn’t be surprised to see 18+ on our best NW peaks.

January 2021 Medium/Longterm Pattern Discussion.
fountainguy97 replied to AMZ8990's topic in Tennessee Valley
Looks like a pretty serious NW flow event to start next week. Those windward slopes will get slammed. And flurries across most of the state. -
January 27th-28th Boom or Bust Snow Event/Obs

Could be worse. Honestly not bad considering I hit 60 yesterday afternoon. 29 now. Going to be a cold day today.
