    OK, why I don't see a snowline down to sea level. Looking at Monday morning. Going on GFS factors, though the ECMWF roughly matches it on T850:

    Long Atlantic sea track from southern Greenland (up to +10 °C), leading to the following.
    1) 500-1000 thickness around a marginal 523 dam in the north to 528 in the south (need more like 521), but more importantly, 850-1000 thickness of around 1300-1305 dam (need sub 1285).





    Anything below 528 DAM is sufficient for snow to low levels however 522 is generally considered 50/50 between rain and snow. So it is very marginal, I agree. But still possible.

    Anything under 1310 carries a snow risk. Again marginal but still possible. The long sea track is irrelevant though. I am tired pointing that out. -5c 850hpa is -5c in the same way sub 528 DAM is sub 528 DAM.

    2) T850 around -5 °C at geopotential of 1250-1350 m. Not enough in a maritime airmass.

    Must be ground hog day. You made the same argument earlier this month. -5c is generally sufficient. Incidentally actual temperature is likely to be closer to -6c.
    3) 850 hPa theta e of around +14 °C. Need below +10 °C. 850 theta-w at best +2 to +3 °C. These two variables would suggest a snowline of a couple of hundred metres.


    +14c translates into around an 80% probability that snow may occur but at what level. You need to correct those figures though because Tuesday is likely to be wet and overcast and there are other variables like sunshine amounts etc to take into account in relation to Monday. So you need to do a bit of calculation maybe knocking a couple of degrees off. You need to take account of more variables IMO but you have a point none the less.

    Those charts are useful as an experimental guide but they have rarely been completely accurate. They are quite good for less marginal conditions.

    Both days are marginal for snow. I am not disputing that. Your point would come across better IMO if you gave a percentage risk of snow at various levels.

    P.S we don't know the exact track of Tuesdays storm yet...so maybe best to keep that from separate just till tomorrow.

    I think I have just copped on to something sinister on this forum.

    'Sponge Bob' and 'Snow Bunny', have the same initials! Have you noticed that Sponge Bob, despite claiming an almost diabolical hatred of snow, is actually the one poster who has very likely used the word 'snow' most often this winter? I don't think there is one post on here where he hasn't snuck in the the word 'snow' in some form or other.

    Beware people, Sponge Bob is a through and through SNOW BUNNY in sheeps' clothing.

    Now DE , I was accused of trolling for predicting what turned out (not fully confirmed yet) to be a 15c on Christmas Day. Bunnies went spasticated at me for that one...they would not hear anything but 'White' bless the little dears.

    Sadly I just couldn't predict a heatwave AND snow ....but I tried to intellectually reconcile them to keep the bunnies happy so I did.

    P.S we don't know the exact track of Tuesdays storm yet...so maybe best to keep that from separate just till tomorrow.

    I know, I just posted it as a final illustration of what also happens to be the way I see it too, going on the other factors I mentioned.

    I say 100 % chance of snow above 150 metres in the northwest early on Monday, rising to around 200-250 metres later through the morning. These levels around 150 metres higher up in the south. At sea level, I would say 20% chance of seeing the odd flake thrown into otherwise rain or sleet showers.

    A narrow window on Monday, before milder air later on, then we'll see what Tuesday brings, but with the airmass already in place before the arrival of the storm, I don't see where the major cold will be to the north of the system (if the ECMF comes off).

    I wasn't being patronising. In my opinion the evidence you posted for your forecast was not enough to back up the claims you were making. -5 °C 850s is not enough evidence, without backing it up with more data, that's all. I'm sure you yourself will admit to being a ramper, so no point in lashing me for saying so! :D

    Let's just see how things go.

    That's a rediculous thing to say. I intentionally keep things as simple as possible so it is accessible to everyone who reads the forum. I won't apologise for that. And I will mention many other variables if prompted to do so. There is no need at all, and I have seen it on other forums, to bombard people with numbers and charts some of them will find bewildering. That does annoy people. I recognise that.

    Is there any chance at all that this thread can be kept on topic? It is only suppose to be for Monday/Tuesday snow risk/potential.

    Well only the other day you said a -5c @ 850 hpa was the same in terms of snow risk no matter what the air masses source, Atlantic or continental, so from that i just presumed you didnt know about surface layer modification or dew points etc. Sorry if i was wrong.

    That's not what I said. I said -5c 850hpa is the same whether it is polar maritime or from Siberia. That's how I put it. Nothing to do with snow risk. If people want to discuss wet bulb, dew points, temperatures through the atmosphere, SST's, the Jet Stream, theta values, strat temperatures, wind, humidity, pressure, heights whatever, no problem. It is not needed in an OP. Generally all these things do get discussed during these threads anyway. This thread and others are being derailed by trolling.

    Yes but it was pretty clear what you meant in the context. It was in response to somebody saying -5 was not enough in a maritime flow.

    They are needed when making a forecast though. In your OP, you made a forecast, purely based on -5c 850hpa temps. Prove me wrong by showing how many other variables are favoring snowfall.

    Can I just point out that not everyone lives at sea level. There are a lot of readers of this forum and if there is a chance of snow at higher level and disruption at higher levels to road conditions, then I do think that it's worth pointing out that it may snow for their benefit.

    I do not live at sea level myself but I do have family that live in the wicklow mountains and they would be glad of such knowledge.

    That would be a waste of time atm as the 00z runs will be coming out shortly. In any case I am not inclined to respond to a post as ignorant as that. There is an ignore button there that you can use. I look at every variable available to us when I make a forecast. Just because I have not referenced them in the OP does not mean I have not used them.

    The conduct and trolling of certain posters in here is not good for this forum.

    Far from me to respond to a troll but take my advice and use your head. How would you characterise this week just gone and the week preceding it? This coming week will be much colder and there will be snow at times next week.

    I really have little interest in communicating with a poster that consistently trolls this forum. As I said to the other poster there is an ignore button. Feel free to use it. Or better yet stop posting rubbish trying to wind others up and opening stupid threads about heatwaves or whatever nonsense it is. Because when you criticise someone in here it says more about you then it does about them. I don't know what your issue is.

    There are forums more wreckable then this one - I would suggest some should journey over to them or preferably the moderators should start taking action here.

    I see MT has this morning gone for a similar forecast to mine.
    Monday will be very cold and windy, with a rapid moderating trend late in the day. Mixed wintry showers with accumulations of 3-5 cms of snow on hills (snow line at times near 150m then rising) ... winds WSW 30-50 mph ... morning lows -2 to +2 C and afternoon readings near 4-6 C before rising towards midnight to about 10 C.

    A brave move, considering the reception I got! biggrin.gifpacman.gif

    Darkman, sorry, I've only just now spotted that you replied to the factors I mentioned last night. The way it was quoted it wasn't clear you had done so.

    From my experience the 528 dam line is only a first indicator of when to even bother to watch out for snow, and we never get sea-level a snowline unless it's at 522 or lower. There is a difference with continental vs maritime flow, with continental flow giving a higher chance of snow for the same thickness.

    Likewise with the 850-1000 thickness, which is a much more important one to look at than the 500-1000. Experience tells me that if it's not below 1285 m then sea-level snow is unlikely. Other factors have to be taken into account too though, including humidity, etc. as these have a bearing on the thickness value. It is not correct to say that -5 °C T850 and 528 dam are the always the same no matter what when it comes to forecasting snow. The boundary layer is where the snow must survive, and the T850 tells us little about what happens to it on a long track over sea.

    This ex-UKMO forecaster thinks along similar lines, though in fact says that the guidelines posted are even a little too optimistic.

    I still stick (get it?) with a mostly sleety rain mix for most, with proper snow briefly above 150 m in the northwest early Monday.

    In my humble opinion, i log on here every day to read MT's forecast and various threads. However things seem to have gone downhill recently, there does seem to be a certain amount of condenscending behaviour going on. I admire anyone who starts a thread and gives their opinion on the forecasts.
    Yes i love snow, its rare, especially in the South East. (Don't like snow bunnies reference to people who do like it:rolleyes:)
    The whole point is it gets people chatting and discussing and surely being the weather boards, thats the most important thing.

    What we are missing here is the 3pm chart which, I confidently forecast, sees the band of snow whipping across the northern end of the Wicklow Mountains bringing snow cover to Dublin to sea level from 10 km inland and above 70m asl near the east coast.

    You can bet the house on this - I've studied Su Campo's reading material and have now pretty much nailed the forecasting thingy.

    btw my assistant in Belgium sees a (small) pile of snow falling - starting before 6pm tomorrow in Sligo/Donegal becoming widespread through the night along the entire west coast (from 5km - 10 km inland).

    East Galway is especially vulnerable (as is Donegal, of course :()

    I certainly can't see any disruption from snow at any time in the near future, regardless of where the low tracks, so I'd love to know how you came to that conclusion. Brief snow on high ground, sleety mix at best at sea level. I think you're way too optimistic and ott, but that's just my opinion.

    Su are you aware how many times over the past two winters you posted on here that there would only be snow only on higher ground - or even had only been snow on higher ground - whilst I was sitting here in the West vitually at sea level with the ground around me covered in snow?

    Hey all, back from my Christmas break, hope ye all had a good one and are looking forward to what the New Year will bring us :)

    Just been trawling through the charts this morning and I don't see anything concrete regarding the snow risk for next week. The DP is extremely minimal everywhere, while coastal regions and inwards of up to 30-50km have temperatures varying from 3-7. Inland sees lower temperatures but its still not enough to muster any snowfall at lower levels.

    My current prediction is one similar to the last snow risk, which was snowfall at 100m+. Things can still change though :p

    Should clarify blizzards and significant snowfall is not what is being forecast in this thread. All this thread is for is a risk of snow on Sunday night, Monday and maybe Tuesday depending on the track of that storm. High ground is always more likely to see snow. That goes without saying. This is why it's problematic when a poster is labelled in such a manner. Posters seem to think whenever I open a thread now snowmageddon is being forecast. That is not the premise of this thread (nor the last one).

    When I say it might snow in some areas I don't mean it's going to settle either. I don't know why people automatically assume these things but it's happening more and more really. It's the same when Weathercheck opens a storm thread - you would think a hurricane is being forecast the way certain posters would respond. And then the criticisms start flying from the usual quarters.

    Su Campu is absolutely correct to point out the marginality for some areas particularly at sea level where we might well be outside the parameters for snow to fall. This is not a competition and opinions like this should be used to make the forecast better and more solid as the thread goes on. So it's great to see interaction like that.

    What is not great is some of the other stuff from others who have no interest in this and are just trolling.

    As for the forecast itself it does look slightly more marginal to me on both days then it did yesterday across the models. Dewpoints and temperatures are slightly higher for the two days aswell. The track of Tuesdays storm is awkward in seeing the depth of cold air it could drag down. The track is not certain yet.

    There is a risk of snow. But whilst snow could fall at lower or low levels disruptive snow is unlikely right now below a couple of hundred metres.

    There is "a risk" of 13c peaks and record 31 dec average minima temperatures today. Do you see anyone starting threads about that ???

    However it would be tedious to start 2 threads about a "risk" of something that will not affect most people in any way EVEN if it does happen ......just like the lack of rainfall in Timbucktoo of a wednesday night does not warrant 2 threads around here either. :(

    It "appears" to me that there is a power struggle in this forum which is taking away from the spirit and fun of the forum. I might even suggest that it is not being correctly moderated by the mods themselves or maybe a bit too loosely?

    Either way I have grown tired of the bickering and I have decided to ban myself from this forum until things calm down and all involved grow up!

    Happy New Year all.

    On a serious point can I say it is astonishing that Sponge got a warning for this post - he is actually making a very reasonable point about notability.

    A "risk" of snow falling over some high ground hardly affects as many people as a warm day!

    In fact Su, you yourself made a similar post (re snow "ramping") only last night.

    Don't be swayed by the crowd - and I note that several posters constantly refer to Sponge as a "troll" - surely that should merit some sanction?

    Strikes me that some of the folk desperate for snow have had a serious humour bypass; it is perfectly possible to just ignore posts that annoy you or you don't get the humour.

    In fact Su, you yourself made a similar post (re snow "ramping") only last night.

    Don't be swayed by the crowd - and I note that several posters constantly refer to Sponge as a "troll" - surely that should merit some sanction?

    Strikes me that some of the folk desperate for snow have had a serious humour bypass; it is perfectly possible to just ignore posts that annoy you or you don't get the humour.


    Its like a yellow card in football match , the foul you just got booked for may not have been worthy of a card but your card is a culmination of constant niggling.

    As you were with the GFS and UKMO 12z's. Nothing new for Monday. Snow risk is still the same - mostly higher ground but to low levels at times particularly through the early hours of Monday morning. Western/Northern parts most at risk of heavy showers. Drier further East but some showers should make it through on a brisk wind. Tuesday is still up in the air (pardon the pun) until the track of the storm is nailed down.

    Sparrowcar and Wild Bill have been banned for back-seat modding. Warnings about this were issued in this thread but yet people still don't get the message. Boards.ie rules are there to be followed, for the good of everyone.

    Sponge Bob received his warning for persistent off-topic posting, and I have spoken about it to him before this. That post was the straw that broke the camel's back, and any more will be met with a permaban.

    If people have a problem with moderators then the rule is to pm them, otherwise they will be banned.

    Then again they may be just drinking heavily.:P Hail comes before sleet normally.

    I see ye say that the risk of snow depends on the height u live in but how can u find out this as most are slightly higher than see level!so is it people over 150m are better or have more chance?
    I don't know much about weather so this is why I ask!

    Thanks in advance
    David.

    Earthtools.org     is a very good site.

    The higher you are the better. The majority of the population lives between sea level and 150 metres, but some lucky ones live higher so they would be the preferred ones.

    There is a slightly colder trend in the models over the past 24 hours, with the Hirlam now showing slightly lower thete-e values reaching the country than the GFS had. The NAE also has theta-w values almost a degree lower than the GFS. These, coupled with a slightly better chance of a cold layer forming near the surface, would mean snow may now survive to lower levels than the GFS was hinting at, with the snowline down to 50-100 amsl over land during tonight and for a time tomorrow morning, with some flurries surviving to sea level.

    Higher ground in the West and North could certainly see snow and perhaps at lower levels for a time, depends on the track of the storm really.
