With the way last year went and the year before and well, the year before. You learn to appreciate every flake.
-
Actually had a few snow showers over the last hour dusting the deck and car tops. Little blue specks show up on the radar but it's mostly undetected on there. Temp is in the 20s.
-
Spent the day in Knoxville, got home about 7:30 and there are still flurries ongoing here. The snow flurries stopped just south of Caryville today as I headed towards Knoxville.
-
I honestly used to get them at least 3 or 4 days a month minimum from late November to late March. Just doesn't happen any more like that.
-
It's a raw, cold, snow shower and snow flurry kind of day. Flakes are coming down lightly now. These kind of days have been rare the last few years.

December 2020 Medium/Long Term Pattern Discussion.

And for people who like to just check here. That Canadian mauler that stalls the Arctic front and lets a low ride the front that thumps the middle valley areas then changes to snow in the East as the Arctic air continues to invade. In circumstances like this with that nice a cold air source. I've found the cold usually bleeds further east than modeled. I'd love to see this one be the one that comes to pass because it really works out for the entire forum. This is about mid-event. It hammers western areas before this and further eastern areas get in on the action after this. -

The 00z GFSv16 put this out for Christmas Eve/Christmas as it's finally coming into Pivotal. It's actually sort of inline with what the Euro shows. Much warmer than the 06 GFS in the wake of the snowfall though. -

06z GFS was more progressive with the cold front blasting through the state around the 23rd into early Christmas eve. Then frigid air rushes in and wrings out what would be fluffy snow to the tune of 1-3 high ratios inches over parts of the area as temps crash through the 20s into the 10s. 12/1PM temps Christmas day -

The Euro cooks up something for Christmas eve as well. It's not the epic bomb that was the Canadian but it throws out some biting cold and anafrontal snow due to the strength and speed of the Arctic air mass. There's hardly even any rain, most of the precip except for the very leading edge is frozen. The Euro ends up here and it may be higher with ratios. Many of us would have a shimmering blanket on Christmas morning. Not much of any melting either as temps go from single digits and teens into the low to mid 20s to lower 30s. -
Changed over to light snow at the house. As I drove to town it was mixed below about 1500 feet.

I suspect we will at least see snow showers and snow flurries on Christmas. It's a straight up Arctic airmass and it will wring out moisture. I'm also convinced it will snow/rain/be cloudy in general on the 21st too. Ever since the perfect eclipse weather I've been cloudy or precip has been falling for every celestial event. I had a seemingly endless evening cloud streak trying to see Neowise. -
Hit 31 then started rising. Up to 36 right now.

I'm approaching 100 inches this year but probably won't quite get there although the GFS has me pretty close with some of it's big totals showing up. Though technically I'm partly in the Cumberland river basin. -

The Christmas time frame has shown up on the GFS a few times too. Looked like anafrontal snow showers. Oddly those have produced two years in a row for me now when not much else has. -
Looks like a decent amount of snow above 2800 feet or so. The entire top several hundred feet of Cross mountain is nicely white.

I saw someone mention that there was another mountain torque event about to happen in east Asia and that the first is what led to the +PNA after Thanksgiving into early December that brought snow and cold to the area. Hopefully that comes to pass. If we can get the PNA to cooperate in late December vs late November those snow chances should become much more widespread and less elevation dependent. Some modeling also that the TPV gets shunted down towards East central Canada and delivers Siberian cold just up stream. Once you start seeing those -20s and -30s heading for the border you have some better source air nearby. We pulled off snow in parts of the area in late November and those areas were in the upper 20s above zero. -
It would he hard to complain about the start of winter imby. The first two weeks I've gotten 3 inches of snow. Two other days have seen snow falling and there's ice/snow in my forecast in the next 48 hours. The question becomes is this a one off like the last couple of years where winter peaked in December then went away, or is it a 95-96/09-10/10-11 where winter started early in December and just kept coming back until mid February? I'll say for here, the December events of the last two years were basically one offs that led into abrupt pattern shifts to unrelenting warmth. This has been multiple wintry events and the pattern looks very favorable again in another week or so after this.

Had a switch over this morning that didn't amount to anything on the ground really. Not checked above 3000 feet. There was no accumulation at 2500 though it could have melted off.
-
37 degrees and just blitzing rain. Looks like there's been some embedded snow in areas out to the west but not super wide spread. There's a small area near Montacello Kentucky where some blue is showing up. Byrdstown just Southwest of Montacello in Tn is down to 34 but ptype says heavy rain there still currently.
-
42 degrees and the rain is actually starting to fall steadily. If I change over I expect it to be after 5am.

It may be wrong but the Euro has been locked in here for a good number of runs in a row. -

The Euro isn't as aggressive as the short range hi res models for western areas but it was better than 12z for middle Valley and Plateau/SEKy areas. -

Pulling for you and Kevin, as well as our mid valley guys. -

John1122 replied to John1122's topic in Tennessee Valley
As we get closer in the snow shield has expanded across Arkansas and now across West Tennessee on the hi-res models. Hopefully it expands state wide. If so it will look like the good Euro run from about 5 days ago. -
