Ensembles are going Zonal in the long range,not a warm look but its not cold either,very little QPFS,probably the only hope would be a bowling ball if it could manifest any cold with it I'm starting to wonder if the CFS is more right with the RMM'S,its been showing it going into WP the last several days,now its showing another Kelvin,Rossby into the WP towards the end of the year and crapping out there,we'll see if it keeps showing this. -

Ill use what the EPS shows,as heights rise into East China/Koreas this should be a warming in the east,BUT during this time the blocking along the Aluetians get shifted into Siberia,this would cause height falls into East Asia,i really think we will have a cold X-Mas,plus the MJO into which seems TO to be maybe in Africa right now maybe or at least western IO -

Be a good case study upcoming in general cause around the 23rd of Nov the SOI dropped,and took out the Nina base state but rose shortly afterwards back towards NINA,so you'd have BN temps towards the middle of Dec but this would be transient because afterwards a few days the SOI would rise again.But the large fall the last few days would tell you it could get rather cold right before X-Mas unlike some of what the models seemingly show,but other teleconnections still play apart -

Strong blocking into the Western Aluetians,Bearing Sea being shown would pump up a +PNA but where does the Trough Axis set up,definite cold look towards the Mid month -

Not sure the MJO is really stalling out,its during the next few days the signal is getting nothing but constructive interference from Kelvin.Rossby.CFS has been showing this for several days now -

Look at the SOI around the 23 of Nov then next week,this is when the models get chaotic with the MJO,but even that today, look how negative the SOI is today,the LaNina base state has been taking out and it is acting more Nino now,seems like the JMA and Euro are going into the COD,then back into the WH afterwards possibly and should probably climb back out the COD,actually the GEFS isnt far behind -

Its just my opinion but when the SOI dropped pretty good around the 23rd then rose before Thanksgiving and the dropped again after,this pattern could should more than likely look like this into East Asis into the first week of Dec,it wouldnt effect our weather until right before the mid month of Dec 29 Nov 2025 1011.21 1008.95 -3.95 14.40 8.89 28 Nov 2025 1011.09 1008.70 -3.12 14.81 8.88 27 Nov 2025 1011.74 1008.55 1.97 15.52 9.00 26 Nov 2025 1012.11 1006.05 20.23 16.24 9.20 25 Nov 2025 1009.58 1005.50 7.63 16.34 9.25 24 Nov 2025 1007.56 1004.90 -1.40 17.10 9.38 23 Nov 2025 1009.73 1000.85 38.17 17.97 9.60 22 Nov 2025 1011.59 1003.75 31.56 17.51 9.41 -

IMHO out in the Pac there is alot of stuff going on with Rossby and Kelvin waves,this is why all the models seem to be struggling with the RMM,even the JMA which has been more tightly bunched is now showing more spread today.You'll more than likely in the next few days see some swings in modeling -

We always here in Middle Tn get hosed by inverted troughs,still remember when we had a Winter Storm Warning that was right before the snow dome talk came in,was suppose to get 3-5" and the models missed the inverted trough and we just got rain instead,because it missed the warm nose -
