================================================== ===============
This forecast summary is my *PERSONAL OPINION* of how the weather may unfold next week. I will take no responsibility whatsoever for any actions arising from its use. It is provided freely in the spirit of freedom and the great love for meteorology that I personally enjoy and wish to share freely with others. ================================================== =============== Summary valid for Sunday 08/08/04 to Saturday 14/08/04 TOI (time of issue) Thursday 05/08/04 2030 UK local time This summary is based on a quick appraisal of the GFS, JMA, ECMWF, UKMO, FAX, and ENS (NCEP ensemble) labelled charts available from the superb http://www.wetterzentrale.de/topkarten Due to the rather unpredictable behaviour of ex-tropical storm Alex as it heads towards the UK all comments below on next week's weather prospects are issued with low confidence. The general consensus at time of issue appears to be that a deep low will end up to the west of Ireland by Monday. This low will then slowly fill, but become complex over a large part of England and Wales. High pressure looks like being maintained to the NE of the British Isles. On Sunday and Monday many parts of England could again become hot or even very hot with a 50% chance of temperatures getting into the low 30s celsius in SE England. Rain and thunderstorms will move erratically eastwards across southern and western areas at the same time. Given the copious amount of water in an ex-tropical strom and very high temperatures there is a 25% chance of some extremely violent thunderstorms. More violent than this week even. Also SW parts are under threat too this time. Rainfall could locally be very heavy with the possibility of disruption, flooding and even mudslides causing severe danger. Even though that is rated at 25% it is highly likely in any case that southern and western parts will see spells of quite heavy thundery rain. With the SE wind North Sea coast regions of Scotland and northeast England could end up dull and foggy but mainly dry, also Shetland. NW Scotland is likely to see the brightest of the weather. The second part of the week is likely to remain, very warm and muggy in all areas with the possibility of more spells of rain and thunder, especially over England and Wales. Meanwhile high pressure is likely to build from the north meaning that Scotland could end up mainly dry and bright with spells of sunshine, but still rather cloudy and misty near the east coast. So to summarise, N. Ireland, England and Wales turning wet and stormy and staying very warm or even hot and muggy. Drier and brighter over Scotland but mist and fog near eastern coasts. LOW CONFIDENCE though. As always this and previous forecasts are available at http://www.lyneside.demon.co.uk/weeklydiscussions.htm This forecast was brought to you from the now world famous meteorological office at Haytor on Dartmoor where old fashioned values of service are alive and thriving in the beautiful Devon countryside.

"Alex" has been a hurricane since Tuesday. It reached its peak intensity yesterday with maximum sustained winds of 105 knots as it passed south of Nova Scotia. This morning, maximum sustained winds were 75 knots but it was well into its transition to an extra-tropical storm as it moved over much cooler waters. Norman.

see the current (00Z) EXO analysis As was mentioned on a Web-based forum, Tropical Storm Alex makes it to the mid-Atlantic, according to the T+24 forecast chart: http://64.246.48.81/pics/brack0.gif (As an aside, I'm sure they used to have FSXX written on them in the top left, but perhaps I'm misremebering) |

And the extended range stuff (48, 72 hr etc., because they had thickness, had a hybrid FS/FUXX header. Can't quite remember when it actually changed; looking at the archive at:- http://www.wetterzentrale.de/topkarten/tkfaxbraar.htm the change for the *analysis* occurred on the 8th May 2003 (though I confess I don't remember it happening); the change for the forecast products probably came in before that, when the requirement to manually merge 48/72 and 96/120 etc., for the old-style 'drum' facsimile was no longer there.

Not just Hurricane "Alex", but 'Major' Hurricane "Alex" (Category 3). Hurricanes containing sustained winds of 97kt or more are classed as Major, I think. Nigel, in parched Romsey, Hampshire (only 0.4mm in the last 15 days and a paltry 5.0mm since 10 July). |
