  1. Yeah, time to wake this thread up! With an Arctic front this strong...that is how it should look. With so much energy, there should be rain changing to snow. I can remember something similar during Jan/Feb 85. The cold basically just took over the front.
  2. 18z is a nice and classic La Nina/NAO run for middle and western forum areas.
  3. 18z GFS is now completely in the Euro camp(edit...eh sort of...clarifying comments in following posts), and a bit less amped. It should provide light snow to much of the forum area and really allows west TN and Arkansas and northern MS to score. I meant to add this for those who have just come back to the board. The GFS update which we speak about is not the one from last year-ish. It was tweeted this past fall again, and hasn't been the same since then.
  4. Again, though. Without the -NAO...we may have seen a stretch of record highs. The Pacific is that bad.
  5. One last note about the -NAO...a strong NAO in December is closely correlated to it returning mid and/or late winter. The CFSv2 shows a zonal pattern to end the month, and potential cold reload quickly thereafter.
  6. One thing I always have to remind myself. We live at a latitude known as the subtropics. It wants to rain here for all but six weeks out of the year(Jan-early Feb).
  7. Additionally, December is rarely our month for snow. It has been recently, but historically the valley rarely scores big snows prior to the fourth week in December. Our best climatology is January to the first week of February. So, we are fighting general climatology as well. NAOs are often the coldest in January and February. In general, it doesn't want to snow in the valleys during December - even old school eras as well.
  8. I placed an answer in banter. Look no further than the upcoming cold shot than to see its effects. An active subtropical jet (STJ) would have had us digging out for a month. Nina climatology (dry) is fighting us all the way. Many historic Kocin storms and historic cold outbreaks have -NAOs. The bigger issue is the lack of frequency in regards to precip. That is related to issues on the Pacific side and not Atlantic. Additionally, one teleconnection is rarely the magic bullet. The PNA/EPO is a great pattern for middle and west TN. Sometimes it is just the luck of the draw. Without the NAO, we are probably sitting in the 70s for December w/ the rising QBO and poor Pacific set-up (to this point). The NAO is actually offsetting some really bad teleconnections. When the NAO relaxes(if we don't have a strong enough PNA), watch what happens w/ temps....
  9. NAO is a much bigger signal for cold in January and February. It is associated w/ many historical cold outbreaks and Kocin storms. Right now we are fighting Nina climatology and a rising QBO(solar as well). One teleconnection by itself is rarely a silver bullet. One need to look no further than the cold shot to see the effects of a -NAO. The Nina is a dry pattern for E TN often - not always. The dry pattern is the problem. If we had an active STJ in conjunction w/ the current NAO....we would need a snow blower.
  10. Will be out and about today, so hold the fort down. The LR on the CFSv2 does have the Chinook. The good thing is it looks like a +PNA type of pattern for January. If so, that will work. We just need normal temps to score in January.
  11. My main take away from last night's runs is that the pattern may very well be active even after the cold front comes along. The boundary gets set, and systems slide along it. Northern stream emphasis is a nickel and dime ticket, but it does pay. The CMC and GFS both have this look. The Euro is sort of on an island after d7....edit the CFSv2 does support is somewhat just not to that extreme.
  12. The 6z GFS, as did the CMC about a day later, has a slider which would give light snow to nearly everyone in the forum area after the 23rd/24th system. I have the discussion for it in the pattern thread so as to keep the two systems separate for now. We can slide it over here when needed. Hopefully, that means that the northern stream is going to be active similar to 14-15.
  13. The Canadian has this but is a day later. That would be a very good look for people also in southern areas of the forum.
  14. It appears the 6z GFS has another round of light snow in western forum areas on Christmas completely unrelated to the storm on the 23rd/24th. Yep, looks like a northern stream piece of energy is diving in along the Arctic boundary. If real, that is a good look as cold air is already in place - a slider.
  15. I am going to use the other thread for the 23rd system for right now. The 6z GFS is trying to get something going on the 25th now as well.
  16. The 6z GFS still goes w/ a powerful Noreaster. It does pop a low over Erie, so it does see the potential for a more westward solution. At one point it has a low was of Detroit, one over maybe PA, and one off the SE coast. There is more snow in Ohio on that run which tells me more energy was held back west of the Apps. I think that is a reasonable run as wonky as it was. The Euro seems too wound up. It makes sense to pop a coastal or a slp in the GOM(which this GFS run has) due to the strength of the front. The 500vort map definitely had a more shallow run over the TN Valley.
  17. At 135, the GFS has a slp in the eastern Panhandle. Got think that is gonna make some sparks here in a few.
  18. Something to consider, the 0z EPS is much different over the Aleutians d10-15. It is much warmer than other modeling in the LR. Its 500mb pattern over the continental US/Canada looks similar to other modeling, but the strength of that low is causing very warm temp anomalies. I can't find that on other models, especially over the eastern US. It makes me wonder if there is an issue w/ the model in the northwest Pacific. It seems like it is stalling systems in error.
  19. Having the ICON climb on board gets me back to 55/45 it is going to happen as the GFS has it. I think the Euro is playing into some old biases. @Holston_River_Rambler, what are you doing up so early? As for me, we had a carbon monoxide detector battery go bad. The periodic beep was driving us crazy. LOL. We have been wondering through the house for about fifteen minutes trying to find which detector was bad. As any good wx hobby person would do, I sat down and looked at modeling instead of going back to bed.
  20. They are probably riding the 89-90 analog. The 500mb map is good for most of Jan(through the 20th at least). The source region is suspect as Canada is scoured by cold. But...we only need seasonal temps to score in January. I tend to lean 10-11 as my analog for this year. There is a pretty decent signal for cold during the second and third weeks of January.
  21. Nah, man. We got your back. And please don't quit creating threads.
  22. The 18z would be a strikeout for much of the E TN valley. I would be super happy for you all out west, and that track would fit the last two great winters for middle and west TN. That run would yield nearly nothing for the E TN valley - model smoothing(high amounts in the mountains) causes the valleys to appear as if they have snow. A slp moving through E TN is usually a non-starter. Still, a LONG ways to go before this system is nailed down. To me, that was a fairly huge step towards the Euro/CMC. It is a cave in that direction. Now, I am not sold on things cutting into this block. Right now, I would set a one from Fayetteville to Nashville w/ backside mood flakes in E TN.
