?Here is a summary of the latest NWP output for noon (GMT) on Sunday. Issued
0426z, 20/10/10. Next week is likely to start with NW'lies across the UK, with showers especially in the north and west. Thereafter all the models except GFS bring milder westerlies, with GFS instead prolonging the colder conditions. ECMWF: http://www.wzkarten.de/pics/Recm1201.gif Low pressure lies to the NE, with NW'lies for all as a result. A ridge moves eastwards on day 6, with WNW'lies covering the UK. WSW'lies affect all areas on day 7 as a trough moves eastwards in association with a low to the north. MetO: http://www.wzkarten.de/pics/Rukm1201.gif The Met Office run brings NNW'lies due to a low over the North Sea. As with ECM, a ridge covers the UK on day 6 and this time they bring westerlies, with southerlies for Northern Ireland ahead of a low. GFS: http://www.wzkarten.de/pics/Rtavn1201.png GFS is different to the European models in that although it shows a low to the NE, it also has a secondary low west of the UK. This creates a col over Scotland and westerlies elsewhere. On day 6 the secondary low moves ESE'wards, over the Netherlands, leaving the UK under NW'lies. A col covers the UK on day 7, with light winds for all. GEM: http://www.wzkarten.de/pics/Rgem1201.gif The Canadian run brings NW'lies for all, this time with a low over southern Norway. JMA: http://www.wzkarten.de/pics/Rjma1201.gif JMA has complex low pressure to the NE and east, with NW'lies for the UK. |
