That's the GFS for you - LOL!

6z run is quite a big upgrade synoptically.

Well to my eyes the ECM from a week back looks closer to this mornings runs than the gfs ever did. Yes GFS has kept with its general theme past couple of days but by no means the winner. 

There is never a winner as the models always ebb and flow towards each other in time just like the weather ebbs and flows every minute of the day.

no use whatsoever lol

Ha, yes. There is a plot with geopot heights (amongst other things):

ukm2.2018011100.168.lant.troplant.n850.f

 

The dashed lines are the heights, but without actual numbers....

Morning All -

I crashed & burned after x2 330 model starts lol-

It’s clear that the overnights haven’t been quite as fruitful as hoped -

The Peter Snow swingometer has had a bit more swing to the GFS - 70/30 now - (70 ECM /30 GFS )

The blocking isn’t the issue- it will be the energy traversing underneath-

just as a reminder here is the 2 big guns lined up 00z yesterday to 00z today 192 yest V 168 today

GFS

871D3D43-F36F-42D0-AA0C-C4E9E19A3CBD.thumb.png.349ddc97b8c300948870c6ee1475ca7f.pngDF8E893C-05C1-4644-90B3-6F055F05A51B.thumb.png.92699b0f14ee0c2d7d1cbb7d12c3e954.png

ECM

22415977-BABC-4459-9539-8173D634DBA1.thumb.png.9de2cfb60bb959dfc18ce70534f0e80d.pngBE2D07AD-5B67-4184-B280-E8BBA1EB7928.thumb.png.ed63f14c0243c36f4724d65a9e673c80.png

It’s pretty clear from the above that the GFS has done most of the changing-

however where the ECM lost some continuity is weaker heights to the East & SE - not allowing for the CAA to rush west.

not quite sure what people are saying victory to the GFS lol.

lets remind ourselves of the 216 00z the day before

BFDF5229-CDEC-4806-BE9F-96D9FDAE4855.thumb.png.64448f822b0e5690fbe6cc32529969ab.pngD60428E9-7441-4F16-AF2C-75766A870D18.thumb.png.78c321f2f801931b9d9ab50a64a257ef.png

The GFS had nothing - ECM pretty good..

 

So there it is expect lots of changes again today -70/30 is the blend - if it gets worse 12z then it may end up 65/35 :)

Any sigh of UKMO 168!?

dont Be down beat yet....

 

ukm2.2018011100.168.lant.troplant.prp.fcst.gentracker.pngTOO SLOW:)

More amplified shortwave appearing again upstream between T120hrs and T144hrs hrs.

This is key as it holds back the PV and more likely to disrupt more energy se wards.

I don't know what to make of it all, except for one thing: whatever the models are saying, the weather will do what it's always been going to do. We just won't know what that is until after the fact...:cold::D:good:

The block to the north east looking like its stronger or am I mistaken here ..

The 1040 high covers more area and the yellows indicate a stronger block

I know a lot of the attention is towards the high to the east but the decider is the initial trough disruption which is greatly effected by the pattern in the east USA.

NOAA highlighted a lot of problems with the models and both arms of the jet re phasing .

The best solution downstream will likely be the one which comes in tow with an amplified shortwave upstream  attaching to the PV and pulling the deep purples away further to the nw.

If you compare the GFS 0hrs run with the GFS 06 hrs in the east USA, note the difference with the phasing and amplitude and see its effect on the PV to the nw.
