Here is a summary of the latest NWP output for noon on Saturday. Issued
0537z, 20 September 2006. The models continue to show relatively warm conditions, albeit with low pressure to the south leading to winds from an easterly quarter. There's a risk of rain moving up from the southwest for the beginning of the week, but even at this range the models are quite varied due to their handling of Helene. ECMWF: http://85.214.49.20/pics/Recm1201.gif The UK lies under a SE'ly flow due to a low to the SW. Winds fall light at T+144 due to a col. By day 7 a weak high moves across the North Sea, bringing easrerlies to England and Wales with southerlies elsewhere. MetO: http://85.214.49.20/pics/Rukm1201.gif The MetO run shows high pressure to the NE and ESE'lies over the UK. The high builds at T+144, introducing ENE'lies for England and Wales with ESE'lies and SE'lies elsewhere. GFS: http://expert.weatheronline.co.uk/pslv_frame.htm As with ECM, SE'lies cover the UK, this time due to a trough to the SW and a high to the north. The winds become easterlies for many at T+144 as low pressure moves over France. By day 7 a trough moves northwards over England and Wales, bringing light winds there and southerlies elsewhere. GEM: http://meteocentre.com/models/glb00_120.html The Canadian run brings low pressure over England and Wales with easterlies elsewhere. JMA: http://85.214.49.20/pics/Rjma1201.gif The Japanese run shows a mixture of ESE'lies and easterlies, with a high over Iceland and a low to the SW.
