Here is a summary of the latest NWP output for noon on Monday. Issued 0559z,
8/07/04. ECMWF: http://64.246.48.81/pics/Recm1201.gif Moderate NW'lies cover the UK, due to low pressure over southern Norway and a ridge to the west. The NW'lies continue at T+144, but they become much lighter for most at T+168 as a ridge moves over the Celtic Sea. By then, SW'lies cover Northern Ireland. MetO: http://www.wetterzentrale.de/pics/Rukm1201.html A small high lies to the west of the UK, with NW'lies and NNW'lies. The high becomes a ridge over the UK at T+144, with SW'lies for Scotland and Northern Ireland; the remainder of the UK lies under variable winds or light NNW'lies. GFS: http://64.246.48.81/pics/Rtavn1201.gif The UK also lies under NW'lies, again due to a ridge to the west and a low to the NE. 850hPa temperatures vary from -1C over northern Scotland to +3C over East Anglia. A ridge moves over Ireland at T+144, with NW'lies elsewhere, followed by WSW'lies and SW'lies at T+168 as the ridge builds eastwards. Day 8 sees another ridge move over Ireland, bringing WNW'lies for the UK. By day 9 the ridge becomes a high over the Low Countries, with SSW'lies for most. The winds become southerlies on day 10, with low pressure deepening to the SW of Ireland. GEM: http://www.meteocentre.com/models/glb00_120.html As with the other runs, NW'lies cover the UK. This time 850hPa temperatures range from +1C over NW Scotland to +4C over SE England. The winds become westerlies at T+144 as the ridge to the SW moves SE'wards and declines over southern Biscay. JMA: http://www.wetterzentrale.de/pics/Rjma1201.html Low pressure covers southern Norway and a ridge lies to the west, with NW'lies for all. 850hPa temperatures vary from +1C over Northern Ireland to +3C over SE England. The winds become westerlies at T+144, followed by SE'lies, southerlies and SW'lies at T+168 as high pressure moves over England and Wales. The high builds on day 8, bringing SSW'lies for Scotland and Northern Ireland, with light winds elsewhere. In summary, today's continue to show a NW'ly spell, followed by increasingly settled and warmer conditions, more especially for England and Wales. |
