GFS op poor and shows how it can go wrong

I much prefer the GFSP route this morning - clean transition

Not sure GFS is poor shows a potential sliding low into cold continental air could result in a decent snowfall somewhere with prolonged cold after it’s sunk into Europe. Anyway won’t happen like it’s shown!

If you look at the NH view on the GFS op at 288 - almost a true cross-polar flow - you’d be forgiven for thinking it’s about to unleash the hounds from hell.
GFSP not too shabby either 🙂

GFS06z op looks like a collapser and is in keeping with an increased number of the GEFS00z perts that I mentioned earlier.

Yes, disappointing in the longer term too

Am I missing something


GFS 6z Op is cold and potentially very snow in FI unless I've got a weird cached version.


Spins a big LP through during initial easterly and rebuilds with massive blocking after that.

The key difference between the GFS 6z op and parallel at 192, is the shortwave in the op located to the north of Norway. It prevents a clean build of pressure over Northern Scandi and displaces high pressure further West to sit just South of Iceland:

https://www.wetterzentrale.de/en/topkarten.php?map=1&model=gfs&var=1&run=6&time=192&lid=OP&h=0&mv=0&tr=6#mapref 

This allows the Azores high to ridge and hang around long enough to scupper any chance of a Scandi high.

The para has a clean pressure build to the NE at 192.

GFS is possibly the best run I have seen in a long time - decent chances for snow throughout and with the slider 200 miles further west could be very newsworthy indeed

I will be really interested to see how supported the 6z GFS is in the ensembles!

You forget, when it looks likely that a cold spell will happen, then everybody starts looking for the perfect cold spell, with beautifully orientated Scandi highs, perfectly placed med lows, and if this doesn't happen, then it just isn't good enough.


Look at one of the largest snowfalls of 1979, it came from a tiny finger of high pressure.

There is so much northern blocking and no Atlantic LP system trying to rush in or Azores HP and this low to our east is moving south westwards and could bring snow in from the east: - It is in FI range and will see where this sits amongst it ENS members but look's perfect doesn't it? - Just 300z away.

A NE / E flow is well supported up to 204 would say 90% showing this direction varying levels of cold. Where they all go from there who knows but support growing. If anyone tells their friends they are responsible for it going wrong

To be honest it's an Easterly, so we're going to get a few wobbles right up yo the wire (if it happens)

and away from deep FI where charts seldom ever verify here is the GFS 6z up to 144 hours.


An unsettled and mild picture with rain at times. The cold air never really gets away from Scotland where snow will continue to feature over higher ground away from coasts.

Well todays runs have woke me up a bit...the GFS 06z is about as cold as it gets for the uk. Long way away but the ensembles support is encouraging.

Whilst my esteemed friend Michael carefully considers his response, I’ll briefly give you my position. I’m as aware as anyone living in this locale of the sometimes dramatic differences in winter  in only a few miles, but I confess the draw of the ocean will always win over the odd elevation related snowfall. If I couldn’t walk down to the sea, especially in the Covid era, I’d probably go mad.
