The gfs goes full on zonal after d10 with a strong westerly flow. This does not tie in with what we have been told to expect so not sure what to make of it:

It must be confused by the SSW and chosen it's default seting

Serious question from a complete novice when it comes to reading the models but is it worth even looking at the models for a period of time if a SSW can shuffle the deck so much so to speak? Thanks in advance.

Wouldn't ignore them. In Feb 2018, the GEFS nailed the Scandi High resulting from the SSW at T384! I recall counting it down from D16, 25 out of 26 consecutive runs had a mean Scandi High, and then I stopped counting because it was clearly going to happen

Throw a good wedge and see what happens?

The flow is still into Europe thou but it is very mobile

I know what to make of it. It’s clueless like the rest of us. Enjoy the week and watch the output with interest for a number of days I would suggest.

Well. With the displacement of the stratospheric vortex to the Atlantic Ocean and the link between the stratosphere and troposphere (downwelling) in my opinion it's quite logical.

Excellent... I'm looking forward to T-258 on the para!

Even in the great winter of ‘63 which was before my time ( I would like to add) there were warm ups and a thaw in between severe cold spells!!

This pattern we find ourselves in currently and what the models are showing for the next 10/16 days is a much better situation to be in in comparison to the last 2 years!!

Come on guys - there will be bumps in the road thru’ the rest of winter and the smaller they are the better!!

Before anyone slates me for mentioning ‘63 I’m only using it as an example not saying it’s going to happen again!!

Thanks

Hmm, zonal flow but would you call it full on and  strong?

Compare it to this from 13th January last year

Of course, it won't happen, but three depressions in five days on a westerly flow is hardcore zonal, more flushing out of excess energy, but a nasty wet period in the unlikely event it happens:

Yes ICON jumps the GFS ship...

So close to something really good if the trough could have dropped through...

Fair play you went against the grain and called what the ECM and UKMO are now showing. At least you still have your house

There were zonal episodes in the run up to the Easterly in Feb 2018 BFTE,,,I think people just need to be patient and let things run their course,,,,,have a look at the charts for Feb 2018 very interesting how it all comes together

It is not against the grain to call ECMWF/UKMO over the GFS.

Against the grain would be the opposite of that.

This was just the usual GFS 24 hours behind.

The GFS / GEFS does have moments of brilliance perhaps this is overshadowed when it does a last minute switch behind all other models. Over years you notice it’s good at spotting pattern changes in FI often closer to time it will drop it, and then eventually go back to original solution. I think the model deserves some more respect it hasn’t done badly at all in recent weeks. I’ve been impressed.

Well I'm excited. What a fascinating period of model watching ahead.  Anyone expecting any of the models having a handle on what's going on up above at the moment needs a stiff drink and a harsh word with themselves.  

Nicely put.

Na, he was saying it before the ECM and UKMO downgrade. Also when the gfs 18z was showing a boom run.

Yesterday some knowledgeable posters noted that the westward progression of depressions was showing signs of stalling.  This was also attributed to the link between the stratosphere and troposphere.

I have to pick upon the comment re the 1962/63 winter. I lived in Birmingham aged 15 then and kept the Met Office recordings from their official Egbaston observatory. The highest temperature between Dec 22nd and March 1st was 4 degrees Celcius. The snow that fell on Boxing day was still there at the beginning of March. It truly was a classic.

I have the Met O  Daily Weather Reports from winter 1963 and the amount of snow that fell Birmingham Airport was remarkable and Edgbaston is a lot higher up and so snowier, although the second half of February was quiet in comparison to January it must have been a great winter.
