That's enough for me. ECM 12z leads me to being 75%+ confident that a
change will have occurred in the European outlook at T240 and that will have had a knock-on effect on the UK. Hence the following forecast at 10 days. At T240, on 22nd November, a European high will have developed. This will have the effect of diverting the Atlantic weather around its northern limb, producing a mild, perhaps very mild, flow over the UK with it's origins to the SW. Depressions will be embedded in this flow, as will transient ridges of high pressure, but the dominent theme will be higher pressure to our south controlling the flow across the UK. As a proxy for this European high, pressure in Berne will be 1020mb. The MetO forecast implies a similar scenario, I think, but there's nothing explicit. "UK Outlook for Tuesday 17 Nov 2009 to Thursday 26 Nov 2009: The general weather pattern is likely to remain unsettled throughout the forecast period with the wind blowing from a southwesterly quarter for most of the time. We can expect showers or longer spells of rain across the United Kingdom, the rain occasionally becoming heavy and prolonged, especially in northern and western areas, and the showers turning wintry at times on the higher of the Scottish mountains. *There will also be some drier, brighter spells, the best of these most likely to develop in southern and eastern areas, especially during the second week. It looks likely to be windy at times with gales near coasts and over hills, especially in the northwest, and the temperature will most likely be close to or slightly above the November average*.

Still 9 days to go, but that European high can really take some shifting, should it become established. |

I'd much rather have it now than a month or two later, though. I reckon that November is a very poor guide to the rest of the winter, whereas a European high established in December or January is much less likely to shift. -- John Hall "[It was] so steep that at intervals the street broke into steps, like a person breaking into giggles or hiccups, and then resumed its sober climb, until it had another fit of steps."

European highs can skedaddle quickly and a strong jet works wonders for that - though there have been instances of them hanging around for weeks and producing exactly the dull, foggy drizzle and 9C that you talk about Will. I also agree with you John, that November is a poor guide to the winter weather. Then again, I think any month, including the one we are in at the time is a poor guide until 10 days out - even then, it is only on occasions when I, or anyone, can be 75% sure. Actiually, I feel that most times 8 days is not a good guide to the rest of the winter's weather! PS Will - "Eurotrash" high! I get the distinct feeling you wouldn't like that 10 day forecast to be correct - and then the charts still show a European high at 10 days on the 22nd! - not much change from my forecast scenario on the 06z gfs, but there's a long way to go and if it is any help, I feel there's a 20-25% chance of that outcome not occurring, ATM, IMO. |

How's your email etiquette? I'm not at all sure you are qualified to comment on the content of this thread, Lawrence.
