I know PSU isn't really a big fan of seeing the PV anywhere on this side of the globe because he doesn't want anything to interrupt the general mid-latitude flow and feels that climo at this time will take care of the cold. I myself say, bring it on. Love seeing the pv rotating around as it provides better cold as well as the potential of better dynamics and extremes with any systems. Now I would take the pv planted around the Hudson Bay region any day of the week because that is probably the most favorable for our location. But I think we are going to see the pv much farther south then that. So though we may risk bouts of suppression we are also looking at increased odds of big and/or extreme events.

Slight differences here and there but overall the look is roughly the same and has slightly improved IMO. Seeing a slightly weaker EPO/PNA ridge but actually a stronger +PNA clocking in. Overall the look there has improved a touch. Stronger ridginging into Greenland and subsequently a slightly farther south solution on the pv. All in all, I think we have seen improvements on the overall look. Love seeing it building heights in the NA. The latest weeklies have legit blocking from from around the 25th onward, which becomes epic heading into early Feb. Link to comment Share on other sites More sharing options...

Given the strat warming event resulting in multiple discrete vortices, we want one of those daughters on our side. I say this a lot, and will continue to say it even after the miss south in Dec- Give me a stout -NAO and a vortex rotating around underneath it. I will take my chances with that look all winter. As we heard ad nauseam in this thread yesterday, weak Ninos tend to favor Miller B events, so this combo can help offset the tendency for NE to cash in while we see scraps.

Starting to strongly believe that we see some great blocking in the NAO domain shortly. Not only that but I think we start seeing some great height builds into and over the pole. Fits in with my thoughts of a very active period from late Jan into Feb and why. Link to comment Share on other sites More sharing options...

Not sure you read my long winded comment to 70/40 but essentially I said don't be counting your chickens before they're hatched. Though el ninos may favor Miller B action in a typical year I am not so sure we will be talking a typical year here shortly. If I am somewhat correct on how I see the pattern evolution occurring in the coming weeks he needs to keep an eye out for major suppression.

poolz1 Posted January 5, 2019 Share Posted January 5, 2019 These are 5 day NHEMI. Doesnt mean there hasnt been an improvement with the FV3 on the handling of individual storms.

Felt it was only a matter of time and that we would start seeing it pop shortly on the models but looking at the long range FV3 it is pretty much showing what I discussed yesterday. We are seeing chunks of pv getting displaced far to the south where there are causing major disruptions within the mid-Latitude jet. All that energy stored in them is being bled off with major amplifications within the long wave pattern as evidenced by the trough we see move into the east at the end of the run. If my thoughts on the upcoming evolution are correct we may be in for exciting times coming up in late January into Feb. To further excite the weenies in here, I am tending to believe this will be a long duration event that may run through the rest of winter. If I am correct we will see a massive exchange of heat from the south into the arctic regions with a subsequent transfer of cold into the mid-Latitudes. That massive influx to the pole will in turn continue to cause major disruptions within the trop pv if not even reaching into the strat with bottom up warming. Now a lot of what our snow chances will be depend on luck but if this plays out the way I think the odds should be heavily stacked in our favor. Either way I am actually getting excited at the prospect of tracking some extreme weather in the near future. eta: LOL. My bad. Was looking at the 18Z run of the FV3 and not the current one. But my comment still stands. Link to comment Share on other sites More sharing options...
frd Posted January 5, 2019 Share Posted January 5, 2019 Still not certain on down well from the strat event. Seems last year was faster, even though there was a lag, where this year the effect from strat to trop have been less so far, however, the reversal in winds is forecasted to last much longer. Read the longer it goes the more likley there will be significant down welling. Of course the ultimate long term regional effects are still hard to pin down. Seems like one vortice want to gather near Hudson Bay. Last year, and the going back even more, I have seen news reports form Siberia, Northern Africa, Italy, etc, that even if a vortice parks close by it can result in severe weather with very cold conditions and much snow. I imagine there is more to it than that and requires a certain pattern but the odds of a high ticket event I feel are higher in cases such as this. The severity issues is also shared by @showmethesnow I think too Link to comment Share on other sites More sharing options...

That trough is so deep and expansive though.. really want to see it weaken/retro a bit more, otherwise it could inhibit development of a -EPO, and also tend to keep a flow of PAC air into the western third of Canada. Kinda living on the edge with the current projected PAC look on the EPS. At this point I think it will retrograde and weaken enough as to not be a thorn in the side of the (desired) pattern evolution. Link to comment Share on other sites More sharing options...
psuhoffman Posted January 5, 2019 Share Posted January 5, 2019 @showmethesnow @C.A.P.E. For the record I said I would rather no PV than a badly placed one. An ideally placed 50/50 vortex is ideal of course. Link to comment Share on other sites More sharing options...

Not going to go back and read your comments but my impression was that you wanted nothing to do with a pv on this side of the globe well placed or not because you felt it was too risky as to cause interference with the general flow through the CONUS.

An ideally placed 50/50 vortex is ideal of course. Many times when we have our 'epic' HL patterns, the 50-50 low can result from smaller vortices being shed off of a parent TPV (sitting in the vicinity of Hudson Bay), rotating down and getting 'trapped' underneath the NA block.
