![]() "ron button" wrote in message ... What do you make of this boys and girls.....? http://www.weatherweb.net/wxwebtv2.php Very good but one *crucial* upstream difference he did not mention on comparing the SST charts was that off Alaska this year it is warm, whereas in 2009 it was cold. The warmth over Alaska will encourage a deeper cold pool over eastern Canada and hence a strong jet. Personally I would go for a stormy December with intermittent normal cold but no real cold developing until we get well into January when the weak AO will start to manifest with more blocking. Mind you if things change this month then I will change my mind too, my forecast will be issued on my web site at the end of November.

The video smacks of someone seeking out evidence for 2009/10 levels of cold and finding the facts that fit (of which there are certainly a few) but ignoring those that do not - rather than drawing a conclusion from the evidence. The Gulf of Alaska SSTs (and PDO state) are indeed a very significant case in point. And the cold pool in the Atlantic is in a different position - this time around SSTs are notably higher in the vicinity of Newfoundland. Stephen. |

"Captain Bob takes a slightly unorthodox view of weather prediction. He uses computer model output, but also includes much analogues information, sea surface temperature and index techniques to improve his longer range guidance." Would you pay good money for "Captain Bob's" forecasts........? =========== I've read some of them, so - no. And there's nothing "unorthodox" about using "much analogues" [sic], SSTs and "index techniques". Stephen. |

Will Very enthusiastic chap, I've had to blank out the sound of his voice as it reminds me of someone in the franchisor game, once that filter was put I found it good. We shall see, but it also follows my thoughts of winter coming early as it did in a couple of other similar autumns that I was comparing to a few weeks back. -- Keith (Southend) "Weather Home & Abroad" http://www.southendweather.net Twitter:@LawnscienceEssx |

Len -------------------------------------------------------------------------- Len, I always like to hear peoples thoughts and analysis. This is where this newsgroup all went wrong when no one was allowed to air their thoughts without being insulted and critised. It is the main thing I miss on this group. I think he was right to say it wasn't a forecast but to just take on face value. -- Keith (Southend) "Weather Home & Abroad" http://www.southendweather.net Twitter:@LawnscienceEssx |

On 12/11/2014 16:51, ron button wrote: What do you make of this boys and girls.....? http://www.weatherweb.net/wxwebtv2.php RonB Just a thought, I take it the SSW shown on those models is only a forecast atm, what certainty is there that it's going to warm etc? Hi Keith, just spent past half hour examining the strat. It is a forecast from NCEP/GFS (fairly reliable) and the warming has propagated down to 30hPa by T+240. Quite a change from T+0 charts (12Z today). *If* it does propagate further down then in circa 2 weeks after propagation we *may* see a pattern change (i.e. circa 4 weeks from now). Having said that I still expect a stormy zonal start to Dec due to deep cold vortex over E. Canada established. Will be interesting to see how things pan out in next two weeks before I issue on my web site. Line I am taking with neighbours at present (as I'm always being asked), is that this month will be wet and that Dec could well be stormy but the winter will *not* be as wet or as stormy as last year. Could it be wetter? :-) I do not mention Jan into Feb at all, except on here and in other places.
