Enough agreement and consistency for me.
**At T240, on 28th Dec 2010, mild Atlantic air will have invaded the UK and the cold of December will be over, at least for a while. An Atlantic regime will be operative, though the change to this milder air will probably be slow and messy, with a wintry mix as Atlantic fronts push eastwards. By the 28th, the majority of the country will be frost free on a night and precipitation in lowland areas will be of rain and not snow in almost all areas. Much milder temperatures than those at present, will be recorded on the 28th in all areas. If the thaw is rapid, flooding could be a problem for some. ** There you go. Whether the mildness lasts, or the cold returns, is another matter and not knowable at present, IMO. |

![]() funny how ogre appears at first sight of mild weather. you been hiding under your troll bridge since mid november? forecast, all absolute bollox of course.

You are also telling the professionals running the Met Office and the GFS forecasting models that they cannot do their jobs. The information Dawlish has used is freely available and can be checked on via the following link: http://www.netweather.tv/index.cgi?action=nwdc;sess= This takes you to a "selection pad" where you can choose your model, the time ahead and the predicted elements. For the purpose of this discussion the 850hPa temperature and see level pressure (SLP) are most revealing. If the link does not work for you, go to "Netweather.tv" and from the top menu bar select "Weather" and "Datacentre". The "Weather Chart Viewer" panel on this page will take you to the forecast model chart display. The best way to use this facility is to go to it daily over a period of several days. If the same story is told day after day and by more than one model, there is a reasonable prospect of the outcome happening. If the forecasts vary wildly from day to day and / or between models, then the computers are guessing. A certain amount of meteorological knowledge to actually interpret the charts (it is DIY with no text interpretation) is also desirable. -- - Yokel - Yokel posts via a spam-trap account which is not read |

I'd just go with 5 runs and agreement with the ECM.

On a different note and back to the purpose of this newsgroup, which it ridicules with every post, the 00z ensembles don't give too much of a clue to the weather at 10 days, with the ECM being a warm outlier and the gfs being a colder run - and there is one hell of a spread after only a few days. It will be interesting to see the 12z ensembles. |

It will be interesting to see the 12z ensembles. I find this a useful tool for getting a feel of what the latest GFS ensemble is saying: http://www.wzkarten3.de/pics/MT8_London_ens.png (Of course that graph has its limitations. For example in an easterly the 850mb temp can be quite high when there's cold air at the surface.) There's reasonable agreement in the 12Z 850mb temperatures up to Christmas Day (though 2 members turn it much warmer for the 23rd and 24th). After that, the lines spread out, though the consensus is that 850mb temps will return to close to the average for this time of year. The operational run is a mild outlier from the 27th onwards. Prior to Christmas Tuesday looks like being the wettest and least cold day, at least in the SE. (The 12Z ECM ensemble 850mb "mittel" chart suggests the same thing but extends it into Wednesday.) Looks from the GFS graph like it could be pretty unsettled from about the 26th-31st, after which it might settle down (but that's a long way out). -- John Hall "I look upon it, that he who does not mind his belly, will hardly mind anything else."

They're the gfs ensembles. Past the 28th anything could happen and it *could* be a very zonal set-up into the new year, with a European high encroaching into southern England. 70F in an English winter, for the first time, later in the winter anyone? *)) |

When will there be a change of pattern ? | uk.sci.weather (UK Weather) | |||
Forecast: more mobile conditions at T240. Pattern change. | uk.sci.weather (UK Weather) | |||
Probably cooler and drier than average, but no distinct pattern at 10 days. | uk.sci.weather (UK Weather) | |||
Nothing to indicate a change in the pattern of Atlantic blocking for10 days, at least. | uk.sci.weather (UK Weather) | |||
