Here is a summary of the latest NWP output for 12z on Tuesday. Issued 0553z,
2/09/05. The models now show an outlook dominated by lows to the north or NW, resulting in northern areas seeing the most of any rain. Hvaing said that, all areas of the UK are likely to see rain at some stage during the first half of next week. ECMWF: http://217.160.75.104/pics/Recm1201.gif The UK lies under light southerlies and easterlies due to a shallow low to the south and a trough over Scotland. Winds become SW'lies for all at T+144 as low pressure deepens to the north, followed by westerlies at T+168. MetO: http://217.160.75.104/pics/Rukm1201.gif Complex low pressure lies to the south of Iceland, resulting in a trough and SW'lies for the UK. The low deepens at T+144, resulting in westerlies for all. GFS: http://217.160.75.104/pics/Rtavn1201.gif SW'lies cover the UK due to a deep low to the NW. SW'lies and westerlies are shown on the chart for T+144 as a trough crosses England, followed by light SW'lies at T+168 as a trough covers the UK. GEM: http://217.160.75.104/pics/Rgem1201.gif The Canadian run also shows SW'lies with a low to the NW. The winds increase in strength at T+144 as the low deepens and moves slowly eastwards. GME/DWD: http://www.wetter.com/home/img/sat/g...020000_120.gif A zonal westerly flow covers the UK as the result of lows to the north and ridges to the SW and SE. There's little change at T+144. JMA: http://217.160.75.104/pics/Rjma1201.gif The Japanese run also shows a low to the NW, this time bringing light SW'lies. The winds become stronger westerlies at T+144 as a trough crosses the UK. NOGAPS: http://217.160.75.104/pics/Rngp1201.gif Light winds cover the UK due to a col, followed by further light winds at T+144 over England and Wales, from a ridge.
