Here is a summary of the latest NWP output, for noon (GMT) on Wednesday.
Issued 0611z, 9/08/03. ECMWF: http://www.wetterzentrale.de/pics/Recm1201.html High pressure covers the UK, bringing light winds to all areas except the far north of Scotland, which lies under moderate westerlies. The high moves eastwards at T+144, bringing southerlies to all, followed at T+168 by westerlies and SSW'lies, as a shallow low lies to the north of Scotland. MetO: http://www.wetterzentrale.de/pics/Rukm1201.html The UK lies under high pressure, as with the ECM run. Winds are light for most, although once again the far north of Scotland lies under moderate westerlies. As with the ECM run, the high drifts eastwards at T+144, this time bringing southerlies and easterlies over much of the UK, with SW'lies for northern and western Scotland. GFS: http://www.atmos.albany.edu/weather/...F/mrfsfc00F108 ..gif Northerlies and NW'lies cover the UK, with a shallow low over the Netherlands and a ridge to the west of Ireland. The ridge moves eastwards at T+120, with northerlies and NW'lies continuing to affect most of the UK. 850hPa temperatures range from +3C over northern Scotland to +10C over Cornwall. The high covers England and Wales at T+144, with SW'lies elsewhere. Light westerlies affect the UK at T+168, with a ridge to the NW of Scotland and another ridge over England and Wales. A shallow low lies to the NW of Scotland on day 8, leading to WSW'lies over much of the UK. Westerlies cover the UK on day 9 as the low fills to the north of Scotland, while on day 10 a ridge brings light winds to all areas except Scotland, which lies under NW'lies. GEM: http://meteocentre.com/models/glb00_120_e.html Unavailable today. JMA: http://www.wetterzentrale.de/pics/Rjma1201.html The UK lies under a NW'ly flow, with a ridge over the Irish Sea. 850hPa temperatures range from +3C over NW Scotland to +11C over southern England. In summary, the runs show high pressure moving eastwards over the UK for the latter half of next week, with a chance of less settled conditions for Scotland and Northern Ireland the weekend approaches. As ever, more runs are needed. |
