Typhoon Tip Posted January 14, 2019 Share Posted January 14, 2019 As others have noted ... the American -based indices are modestly impressive moving forward over the next two weeks... Both a 'mop-ended' AO and well-correlated NAO curve have means less than 0 SD ..particularly heading into week two. One thing I'm less sure about is whether the AO is being handled better(worse) than typical performance of the ensemble mean (GEFs). It is not abundantly clear whether the SSW over the last three weeks truly propagated into the tropopause sigma levels... a total evolution that is crucial in the AO modulation/correlation. We could have a negative AO from multiple different forcing mechanisms ...and it is not abundantly clear either, how those varying sources may - if by indirection - be entangled. For example ... late phase 7 through phase 2 MJO waves are correlated with -AO. However, that -AO could be defaulting, because the mid latitude cyclogensis regions are enhancing in mode during said MJO phases ... which lends to enhancing the easterly Hadely trades along the 55th parallel around the hemisphere - that makes the AO negative... But it may not be the same negative as that associated with blocking at high latitudes (necessarily)... Which, the latter is drawn up in the SSW --> -AO total model. If there's a causal link between those two methods - admittedly, ...I may not be aware... but the papers I read seem to re-enforce either but not as an integration. QBO is variant relative to both ...so that's a little murky. Either way, AO may be a wild-card as to how deeply descended the SD goes... The NAO may merely be concomitant do to their overlap... but, others have noted the EPS is looking more and more west based -NAO like ... Again, separating which is pulling which lower is troubling. Meanwhile, I still have no idea what the Pacific arc looks like... It should look AA ... but, seeing as the march through phase 8 was a labored battle, regardless of model sourcing, that suggests for me that the WPO and NP/EPO arc were at those times, not favorable to +PNAP over N/A... Seeing some coherent tenor changes to ward more +PNAP however, perhaps backs us into an assumption that those are improving, as -WPO( - (NP/EPO) ) and the AA phase out there very highly correlates to +PNAP ... So a bit sloppy ...admittedly. Governmental appropriations/shut-down is limiting some... I don't pay for EPS products ... I don't know what that organization's specific index numbers were or are heading... Having said all that... we are in a new pattern. The establishment of quadrature PV into SPV's ... is instructive. We'll see if it pays dividens to winter enthusiasts... but already as we all know there is a steady diet of entities/time periods of interest looking out through D10.

MY comment and point originally was only that I did not buy into the snow idea all weekend form Friday to Sunday/monday. That was my point. Some were really hitting on the snow all weekend idea and thats what prompted my original comment. Sure sometimes it happens where it continually snows lightly or whatever, but it's very rare imo...and in my experiences. And I didn't buy into that idea at all...and it seems to be the case.

mahk_webstah Posted January 14, 2019 Share Posted January 14, 2019 Isn’t it great to have so much to track? We have an even started looking at was probably coming after the 23rd. I think Friday will try and stronger which will just serve to make Sunday better for more. But I think the real biggie comes after that maybe 7 to 10 days later Link to comment Share on other sites More sharing options...

mahk_webstah Posted January 14, 2019 Share Posted January 14, 2019 The reason I think Friday will trend stronger is because we see that so often. If this side of initial wave doesn’t quickly dissipate from the models they usually grow stronger. If this Was a series of three systems that I would put my money on the middle system, but as far as I know this is 2 waves Link to comment Share on other sites More sharing options...

Greg Posted January 14, 2019 Share Posted January 14, 2019 The 850's stay well off shore. This would be a quick hitting wet snow with maybe graupel/sleet on the very tail end of ICON as precip lets up. Link to comment Share on other sites More sharing options...

ICON I’m talking boundary level temps on Friday day for SNE. Away from elevations and central New England . Not 850’s of -1/-2 I see slushy coatings much more likely as of now for pike /95 area if it’s snow Link to comment Share on other sites More sharing options...

Sn0waddict Posted January 14, 2019 Share Posted January 14, 2019 ICON is a snow thump then a changeover despite a great track and very vey cold surface temps. Take with a grain of salt but it’s nice to see that’s not an inland cutter. edit: changeover for SNE. Every else is all snow. Link to comment Share on other sites More sharing options...
