January 15th-17th 2024 Arctic Blast/Snow Event

I'm resigned to the fact that Chattanooga is mostly cursed in these setups. I honestly can't remember a good statewide Tennessee snow where Chattanooga managed more than an inch or so. It's tough watching areas within 30-50 miles of our area getting plastered, and we are hoping to manage a cartop dusting up to 1". It also happens here often when Georgia gets a good 3-6" snow, and we are just too far north by 30 miles or so and get nothing. That's just the way it is around here.

Even the system rolling in on Monday looks to have most of our qpf used up as a cold rain before switching over, if it does at all.

I'm still pulling for everyone else to get a good thumping and some miracle 50 mile jog south of colder air and decent qpf for our area. We need a surprise.

I know the feeling. Seems like I'm always on the cutoff of the bigger systems. I'm just happy anyone on the forum is getting some winter action. Actually having something to track has been a lot of fun (and frustrating) lol. It's definitely better than chasing 60 and 70 degrees temperatures in the middle of winter.

Feel your pain with this one. I'll be in the same boat. 30hours of light drizzle while 30miles west it's 8" of powder.  
 

we hug the RGEM until the end! Haha still hope for us far eastern folks!

I completely understand that. One year in the 2000s, back around the time Stove was referencing earlier, it literally came a 4+ in snow in every single county in the area except here in my area.  It was around 4 events that I just missed to the West, East, North and South. There was about a 10 mile circle with almost nothing and I was in it.

Not sure I'd sweat it too hard.  Rgem loses the flow for like a 6 hr panel at hour 67.  It looks like an error to me since prior runs don't disconnect like that and it picks right back up at like hour 72ish.  Would be a good hit for JC

Pretty normal oscillations happening, IMO.  In the overall scheme of things we see models waffling back and forth about 75-100 miles.  Probably not unreasonable.  We can all hope the overrunning is a bit more robust when we get to game time.

Yep, there's going to be a snow band that's probably 150-200 miles north to south but because of the angle, someone likely gets left out. I am surprised the window actually opened wider vs 12z and 18z when it was narrowing.

Overall the 00z models have shifted away from the larger overrunning shield and to a much more focused and thin overrunning band. In general most of them did sag southward some. 
 

00z really trended away from the widespread TN event and to a more focused band of snow. 
 

Probably see alot of wobble back and forth with the location of the boundary and overrunning. It's a very touchy system. This one will be stressful up until go time.

I honestly don’t think there’s any trends at this point going on. Feels like mods are just bouncing back and forth 50ish miles or so every run. The issue is the margin of error is pretty thin considering we are looking at 150-200 mile swath at the most for a significant amount. I’d say the big swings are over with at this point. Feels like the southern plateau up to Crossville is probably a safe spot to be in. I won’t be surprised if the bouncing around continues up until kickoff. If I had to give an opinion, I’d say the best thing for a forum wide event is for the mods to come in a little SE and hope the mods are underestimating the NW precip shield which they have been known to do.

Agree 100%. Remembering back to similar overrunning events the precip shield was often greatly under-modeled.

Alot less qpf over a greater area and a southern sag, and a much less northwest trajectory.  Really kind of dramatic between 0z and 12z considering the small amount of time.
