Here is a summary of the NWP output for noon (GMT) on Saturday.
Issued 0505z, 30th September 2008 The weekend looks like ending on an unsettled note, with low pressure close by. All areas will see wind and rain and the pattern will remain similar into the new week too. Analysis and evolution to T+120 via GFS http://85.214.49.20/pics/Rtavn001.png Westerlies cover the UK, with a low to the north. The westerlies strengthen tomorrow as the low deepens to the ENE. On Thursday a trough moves SE'wards, leading to WNW'lies for all. NW'lies persist on Friday, with a trough to the east and a low to the NE. T+120 synopsis http://85.214.49.20/pics/Rtavn12014.png / http://85.214.49.20/pics/Rtavn1201.png http://85.214.49.20/pics/Rukm1201.gif http://85.214.49.20/pics/Recm1201.gif / http://www.meteociel.fr/modeles/nogapse_cartes.php The jetstream chart shows a strong jet over the western Atlantic with a much weaker flow over the eastern Atlantic and the UK. The 500hPa chart shows upper westerlies over the UK, while MetO has WNW'lies aloft instead. ECM has upper westerlies and GEM shows a low over the North Sea and upper NW'lies for the UK. At the surface, GFS shows low pressure to the west of Scotland and light winds for much of the UK. Southern England and Wales sees strong to gale force WSW'lies, however. MetO has a weak ridge over the UK and westerlies for most, while ECM brings strong SW'lies with a low to the NW. GEM has low pressure over the North Sea and a trough over Scotland. Winds are SW'lies for England and Wales, with northerlies or NNW'lies elsewhere. Evolution to T+168 Day 6 with ECM brings a deep low to the NE and a trough over eastern England. Winds are NW'lies for most as a result, followed by southerlies and SE'lies on day 7 ahead of a low to the WSW. On day 6 GFS shows SW'lies for most with a low to the west of Scotland. SW'lies persist on day 7. Looking further afield On day 8 with ECM low pressure covers the North Sea, leading to southerlies for Scotland, SSW'lies for Northern Ireland and westerlies elsewhere. On day 9 a deep low to the NW brings strong to gale force SSW'lies and on day 10 the winds ease somewhat as the low moves NE'wards. GFS brings a low over Ireland on day 8, with southerlies and SE'lies over the UK as a result. On day 9 the winds become SSW'lies as another low approaches from the west. and on day 10 moderate SW'lies cover the UK due to a low to the north. Ensemble analysis (http://91.121.94.83/modeles/gens/gra...ille=Lon dres) The ensembles show a cool spell to end the working week, followed by a wet spell with temperatures around average. |

Sorry to hear of Demon problems; I used to be a customer of theirs (my first ISP/dial-up) and always found their service good, so was sad to hear from many here that the newsfeed wasn't what it might be.
