An interesting post from Ian Fergusson in the south west forum: Hi, just a very quick interjection to offer clarification, as I think there's a potential misreading developing here of the UKMO viewpoint regarding the (longer) medium-range prospects. Firstly, I should stress that (in advance of any interesting / noteworthy weather) the short-term NAE and high-res forecasts for our region are regularly fleshed-out on my blog (such as updates through yesterday - see http://bbc.co.uk/ianfergusson). However in my last entry, I've also started a 'generalist' style dip into how the medium-range guys at Exeter are assessing the 6-15 day modelling. Rather than me blather-on about it here, let me quote directly some salient expert thoughts from our latest (late morning) detailed Met Office briefing. I trust these 'snipped' passages offer suitable clarification on the collective thinking down in Exeter.... "4. Trend For Days 10-15: Lamb weather types are unbiased easterly with a below average Shannon entropy. Hence probably slightly higher confidence in this period than for day 6 to 7.5. Discussion: The deterministic models are well split for day 6 to 7, and the ensemble means have a col near the UK (showing a wide spread of solutions). Thus a very messy, temporary breakdown from the colder weather on day 6 to 7 (with low confidence in all detail). However, all ensembles want to bring back a southeasterly during day 8 to 10. Confidence is thus moderate for a return to a more continental airflow with a drop in temperatures. If anything, the signal for day 10 to 15 is even stronger, and backs the flow more to an easterly."
