  1. The current band (trough?) currently around humberside to newcastle is interesting.

    From memory this morning, the forecast was for potential snow about 6pm. On its current track, this looks plausable. I doesn't seem to be breaking up as much as the other 'scraggs' of ppn that were trying to move in land.

  2. hahaha!! thats funny cuz I just finished watching the BBC news and weather, and they just said that the -22C that was recorded was lower than Finland and Norway lol!! I guess not!

    Qutie depressing downgrade for good ol' Notts and the like, as the strong easterlies they were predicting to bring in the "snow showers" is now only from E. Anglia southwards, where the south will now get even MORE snow. Sunday looks w*nk as well now, so it seems to be going all t*ts up AGAIN. doh.gif

    Just keep an eye on the warnings...I would expect these to change/amend.

    Regarding temps, the guy I was speaking to also said about 400km north of Oslo recorded -45oC, and i've heard a similar figure for somewhere in North Sweden.

  3. Have you not been in the model thread this morning? Good agreement between most that the cold period is coming to an end around Wednesday/Thursday next week.

    I've been in there Strider, and posted as well :yahoo:

    Have a look for my posts for my thoughts (you can do this by clicking on my name), but also have a look at posts from the forecasters as well. They have far much more superior knowledge than me.

    But basically, we do lose some of the colder uppers, but on the ground, things look positive (using GEFS and ECM ensembles) to remain around 0oC (max temps) until next weekend (at least for Derbyshire :) ).

    I was on one yesterday, as I didn't look at the T2M ensembles, and just went on the upper temps. I was wrong (pointed out by Nick F from the team), and would suggest this is exactly what people are doing this morning.

    But i've reverted from my sins :)

  4. First, good morning all you midlanders :)

    Secondly, no worries for Sunday as of yet. Perhaps a slight change of the diretion of introduction of the ppn, but overall, we end up with a similar effect.

    I was also going to post last night (and in reference to Conors post), but was in bed (and the Mrs would not have been happy for me to go downstairs to make a post).

    For anyone that watched the BBC Midlands Weather and (just a few minutes later) the BBC National Weather, must surely have had a Harry Hill TV Burp "FIGHT :) " moment. Local weather was going for snow, yet the national weather showed it missing here. Perhaps the national weather forecast was more up to date, but either way, it beat the local weather forecast hands down.

    No snow here.

    Also, for those looking at the charts. Never (like I did) forget to look at the ensembles T2M tables. Seriously, bar 2-3 days at about 1oC, max temps are looking at no more than 0oC until next weekend, with some back up from the ECM ensembles.

    It looks like, forgetting the snow, it will remain chilly.

    Also what i find annoying is the fact that she talked about persistant snow for england and wales , which will stick she said , but the charts tell a different story . I think them charts are pathetic to be honest they change every three hours . Sundays game on and by tonight that will be verified .rolleyes.gif

    Look at the charts as a guide. <T+48 is the best indication, with <T+24 really beign the time to watch.

    My personal opinion, for the later, is to watch the BBC national forecasts, and view the UKMO charts as well.

  5. Well, i'm going to completely contradict myself from the last few days.

    The GFS, as it has done for around a week now, shows the 850's creeping above the -5oC for a 2-3 days period (all based on Derbyshire), with them returning below for a 3-4 day period.

    Looking at the model comparison, we have a similar set up from the ECM.

    However, look at the GFS T2M ensembles. For Derbyshire, it is not until the 18th/19th before we get above 0oC as a max temp.

    Personally i'm sceptical about the snow potential, but those, such as Nick F, who have much more experience and knowledge than me (perhaps an understatement), disagree. So, you know who to listen to :cold:

    Overall, remaining cold...potentially until the end of next weekend/early the following week.

    Just to also add regarding the T2M for the ECM. I think i've found them for this mornings run, although the format is slightly different to what I have seen.

    There is good back up from the ECM (which also has a similar pressure pattern to the GFS Op) that T2M will struggle to get above 0oC by the end of next week. In fact, the spread is quite impressive, especially as you move through next week, with the higher end of the ensembles remaining at 0oC, but it goes further towards -10oC as well right at the end.

    Those SE'lies are not bitterly cold at all. If that chart is to be believed we can expect 4c minima in the S by Thursday:

    Not saying it will happen at all, but people seem to assume that just because the flow is SE'ly it will be cold. Yes, parts of Europe are now bitterly cold and a surface flow from these areas would bring correspondingly cold temps. However the flow is now predicted to have a more southerly element bringing it off France rather than Germany, which is nowhere near as cold (see above chart). We need as much of an E'ly element as possible helped by undercutting low.

    But if you look at the ensembles, for Kent, 80% (or at least bar the op run + 1 other member) goes for temps of 0oC. I think, at this point, 4oC is much less favourable than an outcome with 0oC. Either way, 4oC is still cold.

  7. Best not not to look at the 850mb temps projected as guide to ground temps though, they do rise on the operational next week (it looks like a mild outlier at the 850mb level into the low res), but at the surface, there's no sign of any milder air - so not sure where you get this milder interlude from. Winds look to continue from the E all of next week, off a very cold near continent - if anything, day time maxima may take a tumble in the south.

    Very fascinating the low temps this morning, even in the south: -17.1 °C at RAF Benson in Oxfordshire; -16.3 °C at Woodford, NW England. Lowest recorded temp for England I think was -25°C at Shawbury, Shropshire in Dec 1981.

    Hi Nick.

    Sorry, should have specified the 'milder' interlude being on the 850's, not on the gound.

    Milder being higher than we have prior to the period of the 13th, but still cold.

    However, main concern is the rise closer to the -5oC mark. Perhaps some variations in the coming days.

    Agree though on the ground temps, and admit, forgot to look at these. Cold, and getting colder, despite any other factor.

    Edit - Nick. Just had a look at the GFS, and would interested though on your thoughts of the Dam Line H500.

    At T+93, the 528 line starts getting cut off, despite the flow being good. Bar around T+252, we struggle to get good UK coverage again. Not sure if this is progged with the op run on the T2m, where it becomes an outlier (as per usual) in the low res, but would have thought that T+93 is still in the high-res output.

    Obviously, in terms of the cold spell, the output this morning is fantastic. But snow potential still reduces on the op run, at least by a text book definition, and unfortunately I don't have access to H500 ensembles for the GFS (might help in determining whether it looks realistic in terms of the other members).

  8. I was going to wait until this morning too post, after reading some of the GFS posts last night.

    I think it can be fair to say, the in the mid to long term, you could say the 00z GFS is back tracking now more towards the likes of the ECM and UKMo.

    However, probably due to the lack of respect for the GFS, one thing that might be missed, is it is still looking increasing the 850's (for example, Derbyshire) on the 13th. However, in terms of 850's it potentially looks more like a revert to the late December situation. A brief milder, but still cold, interlude, with a return to further cold afterwards.

    I am by no means saying that the GFS is correct, and I would agree that overall, the ECM does perform better (but the 12z GFS does quite well). But, if this rise, albeit very brief, does occur, then the GFS will have picked this up 7-10 days before the event happened.

    What I would suggest, is that perhaps the GFS is good at picking up initial signals of changes, but not very good in modeling them past this point.

    I want to check, but also as a guess, the 13th, and probably the following couple of days, have now moved in to the Hi-Res? So perhaps good at picking up signals in the low res, poor at their development?

  9. I've got my eyes towards Hull and Grimsby on the radar...there are a few showers queuing up to hit Hull, but whether they'll make it inland to Nottingham, who knows! :mellow::D

    Not sure really.

    I didnt expect to wake up to snow falling this morning, so might happen.

    The wind slightly changes direction later, so it might push them more towards us.
