    If the 'snow' does come to fruition for the East coast, can I ask what effect the Isle of Man would have on blocking certain sections of the east coast from snow? We seen it last year with the north East winds bringing the clouds over the Irish sea from England/Scotland and then dumping their load (so to speak on the Isle of Man) and these clouds then disappearing.


    The Isle of Man is perfectly posistioned to create a rain shadow in a showery regime - not so in a frontal situation. Yes, that would likely occur again but it depends on the wind direction. First thing is first - get the Easterly in place first.;)

    Considering the upgrades in the past 24 hour nothing can be ruled out in terms of further upgrades and shifts in pattern west.

    This has two years ago all written over it.

    A rain front went over the East during the day and on to the West . It was due to come back to the East that night when it was cold and give snow. Mullingar etc got the snow but the front broke before it hit Dublin.

    So i believe this will happen or i will be running a race in bloody cold conditions in Raheny:rolleyes:

    I am actually not focusing on Monday tbh but more after that. Monday looks "interesting" but no more then that at this point. Will still have to be watched carefully because as has been said a bit of tweaking and there could well be sleet and snow to low levels.

    Sure DM2, I appreciate that.

    I'm more just throwing in my comments/tuppence as some may interpret this thread as a 'it's going to snow thread' and we all know the fall out that can happen when it doesn't! :o

    I find these charts good for pin pointing the cold boundary.

    Here it is @ 48 hours

    We need the dark blue boundary to push in over the east coast in future runs ;)

    Rtavn487.png

    And @ 72 hours

    Rtavn727.png

    Question: See the green part running up from the south, what is that ???? Any of these?...Overwhelmed azores high weakened by the cold or is it warmth carried on the tail of the jet stream? or what?

    Can't quite figure out what overwhelms the highs... some charts had warm pushing up with some extreme cold either side, I would have thought that it would have been squashed... how does it fend off the cold? (prob some really simple phyiscs law I am missing here, pardon my ignorance)
    Thanks

    Good GFS run and increasingly exceptionally cold. We never get a proper undercut from the Atlantic but we never really need it.

    latest GFS run is showing a massive upgrade, from what I can see, more so in the medium term. I was all set for things to fall apart but not this

    Big upgrades all around today! As always just in case anyone has already managed to forget, :pac: remember that it can swing back the other just as fast.
    Although i must say even this recent turn in events has got me believing! /ramp

    Ha, ha... just saw the GFS... no wonder they are gone mad over at Netweather!

    But the serious cold is still in FI, beautiful to look at but will probably pegged back in the next run. Just goes to show what potential is actually in that easterly though... :cool:

    GFS and the UKMO models mostly agreeing up to 144h were the UKMO stops, If the ECM take's the same line this evening this is going to be fantastic stuff.

    If we get the three models to agree its looking good very good.

    UKMO 96hrs

    Rukm961.gif


    Some agreement at this timeframe now. It's important whilst post 96 hours looks nice and plausible on the GFS to keep a level perspective. We are good up to 120hrs atm IMO. Pretty solid agreement at this stage and i'm sure the ECM won't have any nasty surprise later. Winter proper starts from Monday.

    Basically the models largely agree the cold will make it across the UK since the Midnight 0z runs...at least as far as Snowdonia.

    Now lets see how the models build it further by midday Saturday. Yesterday they only had the cold reaching to the East of the Pennines in England.

    Alot more energy going south into the Atlantic on the jet stream. The GFS had the bulk of the energy going to Iceland and Greenland. Looks a whole lot different now.

    For us to have another 1982 the cold needs to move another 200 miles west, mug a few atlantic wet fronts like the one coming across on Sunday, and then freeze it hard in situ.

    So far the models have shifted it 100 miles westwards, only 200 to go. However another 100 miles will give the East and Dublin some (perhaps a lot?) snow and as far as Sponge Bob is concerned ye are welcome to it. :D Sure it could be another 1933 .....never mind 1982..and I would be just as happy.

    Now lets all be patient, what will happen will happen. :D
