The wind will probably be the most impactful event with the first storm.  The intensifying low will have strong gradient winds we'll all experience, and a mountain wave event could also result from the strong southeast low-level jet over the Smokies as the low travels up the plateau.  The mountains and foothills will likely observe damaging wind gusts at some point.

The models are trending to more progressive and less phased situation and are starting to recognize the drying effect or those nearly due west winds. 

Now even most of Indiana is probably out of the game due to those westward winds and a faster/more progressive system. It looks like the GFS may actually be ready to take a model victory this time.   

With that still said 1-3 inches of snow is still a good bet for the Plateau especially from Bledsoe/Van Buren Counties and points north.

Plateau is definitely going to witness a nice little event. I think 1-3" across that region is probable, with localized amounts of 4" possible.

Outside of the higher elevations, probably snow showers and maybe a quick dusting from a heavier band or two.

I live in Johnson City at around 1,900 feet and we usually get 1-2 inches out of these type events. It shows the high temperature here Tuesday at 31 with a low Monday night at 24 and down to 19 Tuesday night. It will be cold enough to stick especially at night. Time will tell

3k NAM is probably amplifying the totals, as it commonly does between 50-60 hours, but it'a showing a nice little event for those of us in the lower elevations of Middle Tennessee, and even in some parts west of the TN River.

I think Plateau and East Tn would like to take 12z Canadian for next 7 days projection . It’s the Canadian...so you know it’s not happening lol.

Mon/Tues is definitely an elevation event, NW facing slopes. Northern Plateau could see 1-3” and Smokies above 3000 ft could see 2-4”, with 4”+ in highest peaks.

The rest of us in Middle/East Tn...scattered flurries.

Early next week will be a shock to the system after so many mild days in the 60's.  Monday will be an interesting weather day, whether or not we see snow, with winds gusting to 35 mph and temps dropping through the day into the 20's after nightfall.  After Monday, a big chunk of TN will not break 50F.  Welcome to winter (at least for now).

It would be a nice Christmas present if the GFS ensembles are correct and we have a -EPO.

That would go a long way in at least ensuring that we don't torch and if the EPO block is tall enough it may disrupt the Polar Vortex but that may or may not be asking for too much at this point.

Look at you, NAM showing 5-8 inches of snow from Robertson/Sumner Counties into Central Kentucky.   

You are trying to get brownie points from snow weenies aren't ya.

Looking forward to seeing some flakes dancing in the skies and feeling that bite in the wind while walking the dog. Love some winter.

Looks like Johnson City is definitely in the 1 inch area. We typically get 1-2 inches out of these type events because of our elevation and proximity to some high mountain tops to our east and southeast. Once in a while we get even 3-4 inches but that will not happen with this event
