  1. Amazing outlook and I have admit to being surprised at the 16-30 day forecast.

    Below average temps and above average rainfall in winter for S Brtitain can only mean one thing and that is N blocking with S,ly tracking LP systems. I very much doubt it refers to only convective E,lys because it would state precip above average only in extreme SE parts and even then I doubt rainfall would be above average.

    I should have more faith in the Met O really because I remember back in Dec 2009 the very cold, snowy outlook was predicted even when it wasn't obvious in the model output.

    Of course we should have more faith in them, they are the pros after all, and 99% of the time they are right.

  2. UK Outlook for Sunday 29 Jan 2012 to Tuesday 7 Feb 2012:

    Southeastern parts of the UK are likely to be largely dry on Sunday and into the start of next week, with clear and sunny spells, and a risk of overnight frost and fog. There is a risk of wintry showers developing near the North Sea and English Channel coasts. Northwestern areas are likely to be cloudier and windier with rain at times and perhaps some hill snow. Temperatures are likely to be average, locally mild in the northwest but colder in the southeast. The weather looks likely to become more settled during next week, although there is considerable uncertainty in the forecast, with an almost equal probability of the unsettled conditions spreading back across the UK, or much colder conditions developing nationwide, with snow in places and widespread frosts.

    Looks to me as thought the 6-15 dayer is siding with the easterly with the mentioning of wintry showers in the North sea an Englis Channel coasts.

  3. Just seen the ensembles and blimey is the first word that comes to mind. When I mentioned the uncertainity last night in the 18Z ensembles I have to be honest I thought I might be straw clutching. Now i've finally looked at the 06Z ensembles and the answer is no I wasn't.

    What some of the ensembles do is similiar to the OP with the trough moving SE. However quiet a few other members keep this to the W and then we see trough disruption with the energy going SE and at the same time pressure building over Scandi.

    The upper temp mean has taken quiet a drop around the 25th and thats a full 5C colder than the ensembles were suggesting yesterday.

    And they could well be 5c warmer by the end of the 12z such is the chaos in the models at the moment. I am just being pessamistic hopefully lol. Probably the best thing to do is to take the mean of the mean ensembles over the course of a week lol.

  4. I'd be dubious of the output past 96hrs as the UKMO and GFS disagree, at 120hrs the UKMO promises much but doesn't deliver at 144hrs but I think we need to be looking to the ne.

    That low is a nuisance to the west especially as the UKMO 120hrs could develop so much better with just a little trough disruption.

    But surely the Russian high is not going to influence us while there is a big fat low in Scandinavia is it?, surely our cold prospects are more likely to come from this trough?

  5. IMO the GFS 06Z looks good up until T120. Heights are increasing with each run over Greenland, and generally each run is becoming colder. The low over Scandi at T120 seems to be heading more East, It would not take much from T120 onwards to give us a N/Easterly. As GP said yesterday expect the unexpected, and IMO don't look beyond T120.

  6. According to the 18z GFS early next week T120 to T168 (I dare not look any further, and anything past T120 is pushing it) looks very unsettled. It would feel very chilly in the wind almost winter like again lol. Still good heights over greenland. If only the lows would start moving SE we would be in business. Plenty of cold pooling over Northern Scandanavia on this run waiting to come our way hopefully.
