  1. Most of the models in the long range models shows a ridge into East Asia,with height rises into East China/Korea,that should be a warm look towards Feb 8-9th around that time anyways for us,maybe some hints also that some sort of change is upcoming afterwards into Mongolia and China on that map.If the GFS is anywhere right we should see a cool down shortly after,this is a cold look in the lower latitude of East Asia,but we all know how the GFS can whiff at this range

    I am starting to feel like modeling has a decent handle on the timing of the upcoming 500 pattern.

    Webb mentioned this on Twitter.  JB mentioned this as well, and so did Cosgrove.  ->  The pattern, which began the days after Christmas and will end early this week, is set to repeat itself beginning Feb 7th.  Now, that might sound like I am speeding up the timeline.  Nope, not in general.  Maybe an argument can be made that modeling has moved forward about 72 hours depending on the metric (500 vs surface temps).  MJO plots reflected that this morning - slightly speeding up the return of winter.  The second week of Feb(7-14) will be similar to the transition right after Christmas.  Ridge gets kicked out.  BN heights (weak at first) begin to nudge under the eastern ridge.  The trough will have little to no cold in it.  Eventually, the trough builds in the East w/ a -NAO building over the top.  Look familiar?  By Valentine's Day, the Weeklies have this:

    By the third week in February, we get this in regards to temps - round 2.  Now, we need BN temps by this time in order to have a decent shot at snow(average temps are higher by this time), and that is what is in order if this model is correct.  Week 1 - warm.  Week 2 - less warm.  Week 3 - cold.  Week 4 cold.  Early March - cold.

    I feel like I have seen this movie before.  Jet retracts.  MJO rotates into colder phases.  NAO fires. Winter.  I do think the MJO is playing a familiar game in which it is too slow to rotate in the long range and dawdles too long in warm phases.  Let's see if the cold is moved up during the next few days.

    Models are just now "feeling" the effects of the recent strat warm.  It is still possible that model mayhem could ensue.

     

    It seems that way.There is some slight differences.When we saw the last jet extension(+EAMT)in Dec the GWO gained momentum we also saw the MJO strenghten into WH headed towards Africa,this time looks different and with question marks.The GWO is certainly,seemingly gaining momentum compared to in Dec but questions still loom where the MJO is going.Also around Christmas the SOI was more coupled with a NINO

     

    25 Dec 2023 1009.91 1007.95 -9.13 -3.78 -6.83
    24 Dec 2023 1007.62 1009.15 -27.25 -3.37 -6.80
    23 Dec 2023 1006.15 1009.45 -36.43 -2.68 -6.55

     

    The SOI in late Dec(top) was more coupled with Nino.Soi as of late(bottom) looks like we are in a NINA

     

    21 Jan 2024 1010.18 1003.25 10.93 5.24 -1.69
    20 Jan 2024 1010.92 1003.10 15.13 3.85 -1.89
    19 Jan 2024 1011.60 1002.65 20.45 2.87 -2.30
    18 Jan 2024 1011.14 1002.35 19.70 2.12 -2.79

    The GWO is certainly on the rise but compared to this time

     

    Oh well its just a waiting game it seems.I posted the GWO for comparison to around Christmas time,its really similar right now

    Hopefully, but it's about gone until any NW flow might happen. It was odd that 30 degrees today felt warm. 

    Still think you can get some more snow.The inverted trough that helped with the warm nose,the cold front is stationary,we could get a few flakes here maybe but seems to me the higher elevations could get something,wont be much but it seems to me you could squeeze maybe a tenth or so before it done.That map is a hour old
