29/01/04. ECMWF: http://www.wetterzentrale.de/pics/Recm1201.html Low pressure lies to the west of Scotland, with strong SW'lies for all. By T+144 the low moves NE'wards, with westerlies across the UK. The winds become southerlies and SW'lies for many at T+168, as another low moves NE'wards to the west of the UK. Scotland lies under variable winds, due to a col. MetO: http://www.wetterzentrale.de/pics/Rukm1201.html The Met Office run shows a deep low to the west, resulting in SW'lies for all. The winds become westerlies at T+144, with low pressure over southern Norway. GFS: http://expert.weatheronline.co.uk/ The UK lies under SW'lies, due to a deep low west of Ireland. The low moves NE'wards at T+120, with SW'lies continuing. 850hPa temperatures range from +3C over NE England to +7C over Kent. There's little change at T+144, T+168 or day 8, although by then there's more of a westerly component to the wind. Day 9 sees WSW'lies for all, with low pressure north of Scotland, while on day 10 the winds become WNW'lies, with a weak ridge to the west. GEM: http://www.meteocentre.com/models/glb00_120.html The Canadian run shows lows to the NW and WSW, leading to strong SW'lies for all. 850hPa temperatures range from +1C over northern Scotland to +7C over southern England. There's not much change at T+144, with SW'lies for all. JMA: http://www.wetterzentrale.de/pics/Rjma1201.html As with the other runs, SW'lies cover the UK, this time due to a low west of Ireland. 850hPa temperatures vary from freezing over northern Scotland to +7C over SE England. The SW'lies continue at T+144, with complex low pressure to the northwest and west of the British Isles. A weak ridge moves over Ireland at T+168, leading to SW'lies and westerlies, followed by much of the same on day 8. In summary, the runs all show a much milder setup for the first half of next week, with SW'lies the most likely wind direction. |
