    06z ICON wants to throw snowballs again. However Model concensus says glancing blow. See what the 12z Ecm throws up again.

    12z ICON just rolling is sticking to its guns thankfully. Very cold and decent snow chance on Sunday.

    Indeed ICON is very different early on, snow showers possible from Saturday evening and has the high retrograde somewhat, staying north of us and keeping a cold flow into Tuesday...

    Don't just sit there, get to a Lidl immediately, you fools!

    GFS 12z a decent correction northwards of upper cold pool.

    Will be interesting to see upcoming evening suites...

    Beat me to it WC, Pretty decent correction northwards accross the models so far, UKMO at +72 hours is a very nice chart. High might not sink so quickly either if the ICON route gains anymore traction.

    Might just be a bit more than a glancing blow looking at these changes early on.


  • Registered Users Posts: 1,984 ✭✭✭BLIZZARD7


    If the energy coming East via the southern tip of Greenland here stays more on a more southerly trajectory then our high may take a trip to Iceland ala the ICON rather than immediately sinking...
    One to watch out for, 12z GFS already slower sinking the high.

    Just to illustrate the difference even the limited northern corrections just now made, see below from GFS for Sunday evening...

    Ah Jaysus my stomach.

    I was almost all in on Monday although would have held off the thread creation until yesterday or today.

    Yesterday it was all off.

    Now it may be all back on again.

    It’s too much I tells ya. I hope Kermit has deep pockets to pay my psychologists bills!

    Definite northward movement on the GFS ensembles.

    A little more and things get very interesting...


  • Registered Users Posts: 1,984 ✭✭✭BLIZZARD7


    UKMO 12z yesterday day 4 vs Today day 3 - That's what you call an upgrade!

    ECM looking similar to 0z run, small bit better if anything. A relatively decent afternoon / evening model watching for snow lovers


  • Registered Users Posts: 1,984 ✭✭✭BLIZZARD7


    Hmmm UKMO is now a bit better than the ECM, GFS is quite similar though, just a little more shifting north please...

    EPS in-line with the UKMO option - Nice improvements this evening -

    Latest 18z gfs has the cold air bit more to the north west


  • Registered Users Posts: 23,270 ✭✭✭✭Kermit.de.frog


    Yes, another slight nudge north. Further north the better (or worse depending on perspective).


  • Registered Users Posts: 16,485 ✭✭✭✭nacho libre


    Well, well, i thought this was done dusted. A great surprise to see these northward corrections. Surely it cant up grade any further, can it?
    It could be snowy at Twickenham on Saturday afternoon!


  • Registered Users Posts: 23,270 ✭✭✭✭Kermit.de.frog


    Quite a few GFS ensemble member runs take things a bit further north. Something like this would see heavy convective snow showers fairly widespread.

    UKMO is back in the room. Big upgrade. ICON aslo feeling the love. GFS still feeling it too but not there yet

    yeah, change in UKMO from 2 runs ago is huge. GEM is great too. Sunday and Monday now looking similar to the Tuesday evening to Thursday morning bit of last Easterly. Suddenly feeling pretty smug about telling everyone about this days ago! Think met.ie are going to have to start putting out an advisory for cold (certainly) and snow (potential now for appreciable snow).

    I thought i'd never experience temperatures like this again in March:eek: Even if they end up being a degree or two higher, absolutely incredible stuff.


  • Registered Users Posts: 23,270 ✭✭✭✭Kermit.de.frog


    GFS in northward shift. Trending toward UKMO/ECM. Not there yet.

    Heavier showers and darn cold though, the cap being lifted from the cloud tops.

    Hi guys . What would the main driver or cause for this to shift north as its doing ? Is it to do with the conditions south or north of it ?
