I'm so confused. Are we going to be hurting for moisture now? It looks like the track has been moving more and more NW. I'm definitely not an intellectual giant when looking at weather maps. I love learning new things though and really appreciate the input here and I feel like even though I still don't personally know much I do learn alot just reading through these threads.

the central vally ratio is like 17,18-1 from the gfs map in southeast forum

That would definitely beef up the totals for sure. I know there are some 15:1 ECMWF maps out there. Maybe someone will share what it would be to match the Kuchara ratio maps we've seen today from the others.

Haha, we sure didn't forget where you guys were last year b/c you were in the crosshairs!  Besides, I have a LOT of family in the northern middle TN area so I always check out what's going on over your way.  I hope the second wave can hold together it's precip field a little longer for you guys.  Some modeling takes that tongue directly into the midstate..

Ive done that many times.  The problem with our local East TN geographic terminology VS forum terminology.  I got were I try to remember when referring to the East Tennessee Valley sub regions of Northern, Central and Southern to say The Great Valley or Central Valley of East Tennessee.  Its hard to remember to do that sometimes though.

At this point we really need to look at trends.  Yes, a slight northwest trend is happening which we all expected.  No way those models were going to pull back entirely.  But...they pulled back just enough to make it interesting and entertaining.  Normally, with these types of systems it is tough without a big low so far to our southeast to get enough precip over the mountain to overcome downsloping.  These central NC systems have a bad habit of stopping at the state line.  I have literally driven to NC(about 45 mins from here) and gone from nothing to 2'.  But today's trends were to the northwest with a more expansive precip shield and a system that backed just enough to get the eastern Valley involved.  And maybe our folks in Alabama and Mississippi will get a taste of winter.  I would have turned in my hobby card if this system hadn't come northwest.  So, glad to know the bias is still there.  Next time we want to see the low in south Georgia with 48 hrs to go...not northwest of Tampa.  The margin for snow in E TN is razor thin, but it is better than having no chance.  The ceiling for TRI is prob 3-6 " with more likely 1.5-3".  I will leave our Knoxville folks to guess for their area.

Yeah, for some reason I didn't realize you were in southwest TN!  We will see what we can do...

Thanks Carvers Gap, Yeah I think I may be the lone ranger over here in west Tennessee.  I haven't seen anyone near me posting on this event since we all started talking about it last week.  It is hard to believe how long we have all been watching this storm.

Being closer to the mountains will help IMO.  The 11-E corridor from your area northward looks to have a decent chance based on the 12z suite.  Obviously, the further northeast that you go...the better.  I am sure you have seen that many times.

We have a few.  Winters in southwest TN have been not the best for winter weather recently.  Still digging for that map. (Edit) Tnweathernut will prob send it to you via the messenger.

15z SREF mean has bumped up again.  TRI at 5+, CHA at 2+, TYS at 4+, BNA at 1, CSV at 2.  There are some big dogs in there.  Just another data point to take in.  I do expect the 18z NAM to hold serve or improve based on that though.

For anyone wanting to hunt and peck themselves, here is the link I use.  THANKS, STOVE!
