    Please continue here with chat with regard to the present cold spell.

    Rain/Sleet/Snow is now being replaced by much drier colder air.

    It should dry up through today with snow showers peppering the east through the afternoon and evening with small accumulations likely in places.

    Turning colder as the day progresses with moderate Northeasterly winds.

    New Years will be greeted by Snow Flurries in the Dublin while temperatures dip to as low as -6c inland.

    Cheers folks.

    So what are the chances of any snow accumulation in Dublin? 20-30% or more if you were to give a guess?

    Looking at the NE radar loop , the precip is shrinking as it moves mostly west and a little south.
    No dp drop here and it's currently dry.
    Radar says precip is a few miles north of here.



    Temps and dew points are dropping like a stone directly behind it. The M2 buoy, according to the GFS, will be sub zero by 3AM. There is no doubt about it that the showers will be snow tomorrow as the higher res output has the 850 temps at -8 or -9 in the Irish Sea and universal sub zero dews. This precip is dieing anyway. You won't get much from it. TBH I want it gone completely by morning so the convection can get going on the Irish Sea. ATM it looks like late afternoon on and the snow showers could last throughout tomorrow night and into Friday aswell. Don't think much if anything will settle here but you have a better chance in your location.

    You can easily get snow at 3c with a dp of 0c or below.
    The fact it didn't happen last sunday was just a flukey mix of uppers being too warm and under cutting lower warm air.
    None of that tonight the trend is the opposite actually.
    Anyhow
    pit time :)

    I had pure rain on Christmas day with an air temp of -2c and a DP of -2.3c......from now on I'll only believe it can snow when I actually see the flakes falling! :P

    True. I have seen snow falling here with temps at 7c. Very much a March/April phenomena as dp's tend to be at there lowest at that time of year in a standard NW flow.

    I have been following this thread among many other weather event threads that have come up in the last couple of years.(Bring Snowbie back!!:))

    I have to say that every time I have followed one, the worst case scenario has never come through.......where I live, thankfully.

    Discussion is always good and if theres one thing we all have to talk about, its the feckin' weather.

    Ive put my ass on the line many a time because of threads on here and I have learned a great deal about the weather in Ireland from it.

    In saying that, one thing runs through.
    Even with the most intricate knowledge of weather systems and paterns, even for localised areas, we are still decades off having the right information at the right times and at best, its a total guessing game.

    I think the devotion some people have given, such as Weathercheck and WolfeIRE over the past few weeks and a certain person in the Bluestacks, is what will make the difference come 10 years time.

    It wont be about what you remember from when you were a little sprog or about the terrible snow your father told ya about.
    It'll be about the thread you read predicting the 10% chance correctly.

    Well it will for me anyway.

    Keep it up lads, we're all learning more every post.

    stay safe those of you who have bad snow and ice


  • Moderators, Entertainment Moderators Posts: 10,295 Mod ✭✭✭✭squonk


    Weathercheck, would you mind mentioning in the existing thread when it rolls over into a new day's thread? I'm trying to follow on a phone in an area with a bad cell reception and the randomness of this thread shift is annoying as it's quicker to refresh my page and I can not tell for a while if no activity means no activity or. The thread being rolled. Even a link to the new thread as last post would be cool. Thanks!


  • Closed Accounts Posts: 6,498 ✭✭✭Mothman


    Horray Dewpoint sub zero :)

    now where is the precipitation...........









    BTW did I tell you the air temp is +5.2C
    :rolleyes:


  • Closed Accounts Posts: 6,498 ✭✭✭Mothman


    The Irish sea has already kicked off
    Light rain in air and on radar I see streamer heading into Dublin.

    Way too warm though


  • Banned (with Prison Access) Posts: 5,524 ✭✭✭owenc


    at last the cloud has cleared to leave us dry arctic air! temps now around 1c but itll be dropping through the day to stabalise itself into the arctic air and id say -10-12c is possible tonight going by met ie!


  • Registered Users, Registered Users 2 Posts: 15,616 ✭✭✭✭Supercell

    Good morning.

    Said you would reach 1000..:)

    Much less lying snow here; that gale last night saw to that; will see full picture when I take the dogs out at flrst light.. But in front of the house it is wearing thinner now at last.

    Just seen the Ulster forecast..

    Full moon and they have snow sitting right above us; but they say the winds will ease.

    Not sure why we are again in the path of snow...


    Ulster
    31 December 2009- updated at 06:00
    Today

    Bitterly cold, but brightening up with sunny spells. Scattered wintry showers, especially in coastal areas. Maximum afternoon temperatures 2 to 4 Celsius, with strong northeast winds at first, gradually easing.

    Tonight

    Bitterly cold and frosty, with further wintry showers of sleet and snow. Min 0 to minus 8 Celsius. Risk of ice and freezing fog.

    Tomorrow

    Bitterly cold tomorrow, New Year's Day, with frost, ice and any for clearing only slowly and lingering on in some sheltered places during the day. There will be some sunny spells, but wintry showers of sleet and snow also. Max. 0 to 3 C.

    Having rubbed the sleep out of my eyes, I see that it was south of Dublin. Streamer dying off now but indicates the potential.
    M2 bouy Dp needs to drop more as its above zero at moment with air temp of 6C
    It'll get my interest up if I see M2 dropping to 4C with Dp -2C

    Yep is too warm, slow thaw on outside here, I suppose we just have to give it time. Hopefully the streamers will get going before the winds swing northerly.

    NE Scotland which should be well inside the cold air is reporting more rain and sleet showers than snow this morning. Is this what we're getting next?:(

    Much quieter on here this morning - people must be losing interest. Don't blame them - nothing seems to be happening as it should!:(

    go here and you will see rain.. www.raintoday.co.uk and look up at ne scotland and you will be surprised:rolleyes:


  • Registered Users, Registered Users 2 Posts: 15,616 ✭✭✭✭Supercell


    I'm getting on and off light hail showers here, I imagine these will get heavier as the day goes on until the wind moves northerly.

    It's showing sleet for anywhere near the coast but anyway what it's showing is not necessarily what's happening - it's only what it would expect the precipitation to be based on current conditions.


  • Registered Users, Registered Users 2 Posts: 401 ✭✭Geezer1000


    Zero snow here and zero sign of any. Hopefully it stays that way


  • Registered Users, Registered Users 2 Posts: 15,616 ✭✭✭✭Supercell


    The showers here are exclusively hail at the moment, no snow or sleet or rain at all.

    My front yard this morning..

    same as yesterday here except the rain is showery and its warmer than at most points yesterday .
    A useless zero dp.

    If this is the artic floodgates open...well it's certainly brought the floods :rolleyes:


  • Registered Users, Registered Users 2 Posts: 3,530 ✭✭✭irish1967


    Dare I say it. Quite a nice morning here. Feels relatively mild. Bluish sky. Hmmm. May venture out thus evening but the way this weather is going I could be snow bound or ice bound by then. We live in hope.

    well i ost my internet with all the snow showers!

    itsa nice dry morning down here, that north easterly really dried things up, much better day,


  • Closed Accounts Posts: 6,498 ✭✭✭Mothman


    I had momentary 50% covering...of hail :)
    Temp drops to 4.7C, Dp rises to above zero
    If nothing else it'll help cool down ground

    Meanwhile M2 5.9C Dp+0.1C at 8am


  • Registered Users, Registered Users 2 Posts: 7,138 ✭✭✭snaps


    arrived at work in connemara surrounded by all white mountains! air temp is rising, now 4.3c, warmest its been for over a week here! no sign of colder air, just warmer air. clear as well now


  • Closed Accounts Posts: 6,498 ✭✭✭Mothman


    4.2C Dp 0.5C

    Just show that a heavy shower will drop temp quite a bit, but will raise Dp quite a bit as they aim to meet somewhere in the middle.


  • Closed Accounts Posts: 292 ✭✭roryc1


    Hello all,

    I have a bad feeling about today, temps just not falling fast enough, it actually feels mild now

    But I am really worried (For Dublin) that the winds will turn northerly before the Irish Sea has a chance to get going .
    I really hope I am wrong :o


  • Moderators, Home & Garden Moderators, Science, Health & Environment Moderators Posts: 18,747 Mod ✭✭✭✭DOCARCH


    3.2c DP -0.6c here now. Nice covering of snow to the tops only of 2 and 3 rock mountains.


  • Posts: 0 [Deleted User]


    moderate squally hail here

    4/0

    Dew points are (almost) everything, keep an eye on those. Dew point is -0.6c here atm - this is good (or at least a huge deal better than yesterday).


  • Closed Accounts Posts: 6,498 ✭✭✭Mothman


    The Irish sea is starting up with a vengeance
    5mm hail
    Was 5.3C Dp -1.0C
    now 3.8C Dp+0.5C

    We may well be in very good business later with 1-2C drop in temps during the day

    winds will slacken on tomorrow and veer n or nw but are likely to veer e or ne again by monday so don't worry.
    There are also indications of a possible scandi high soon which would be bingo for the east [irish sea effect snow] as the continent is cooling rapidly and theres all that lovely very minus dewpoint air.

    This set up is the epitome of a watched kettle :)
