Here is a summary of the latest NWP output for noon on Sunday. Issued 0605z,
7/04/04. ECMWF: http://www.wetterzentrale.de/pics/Recm1201.html Westerlies and WNW'lies cover the UK, with a slack low over the Faroes and a ridge across England. The winds become NNW'lies and northerlies at T+144 as a ridge builds to the NW, followed by more northerlies for most at T+168 as the ridge moves over Scotland. MetO: http://www.wetterzentrale.de/pics/Rukm1201.html The Met Office run shows westerlies and WNW'lies across the UK, with a ridge over the North Sea. The ridge moves southwards at T+144, with the UK affected by westerlies. GFS: http://64.246.48.81/pics/Rtavn1201.gif SE England lies under a weak ridge, with a trough over the Irish Sea bringing WNW'lies and WSW'lies for much of the UK. 850hPa temperatures range from -5C over Kent to freezing over Wales. Westerlies cover much of the UK at T+144 and T+168, although they're lightest over southern England. By day 8 a secondary low lies to the SSW, resulting in southerlies and SSW'lies over the UK. On day 9 the low deepens to the south of Ireland, with SE'lies as a result, followed by ESE'lies on day 10 as the low fills over the English Channel. GEM: http://www.meteocentre.com/models/glb00_120.html The Canadian run shows light WNW'lies for the UK due to a ridge over Biscay. Low pressure deepens to the west of Iceland at T+144, bringing stronger WSW'lies to Scotland and Northern Ireland; England and Wales remain under light westerlies. JMA: http://www.wetterzentrale.de/pics/Rjma1201.html The UK lies under a ridge, with SW'lies for Scotland and Northern Ireland. 850hPa temperatures range from -4C over Norfolk to -1C over Cornwall. The winds become westerlies for all at T+144 as the ridge sinks southwards, followed by stronger westerlies from a deep low to the NW at T+168. By day 8 a trough crosses Ireland, bringing westerlies there, for Wales and southern England, with SSW'lies elswhere. In summary, the models now show the cold spell coming to an end for the beginning of next week, with westerlies or WSW'lies for much of the UK. As is often the case, it looks like the further south and east you are, the more settled it will be. |
