Here is a summary of the latest NWP output for noon on Wednesday. Issued
0525z, 8 Apr 06. The runs show an unsettled spell looming for much of the UK, with low pressure to the north bringing brisk westerlies for the UK. As usual, southern and eastern areas will escape much of the rain, whilst northern and western areas will see a fair bit. ECMWF: http://217.160.75.104/pics/Recm1201.gif The UK lies under moderate westerlies with low pressure to the north. Low pressure deepens to the north at T+144, resulting in strong to gale force westerlies; there's more of the same at T+168 as the low moves slowly NE'wards. MetO: http://217.160.75.104/pics/Rukm1201.gif MetO also shows a low to the north at T+120 and T+144 with moderate to strong westerlies on both days. GFS: http://217.160.75.104/pics/Rtavn1201.png A trough lies to the west, this time leading to SW'lies and WSW'lies for the UK. Winds become lighter westerlies for most at T+144 as the trough pushes eastwards, although northern Scotland lies under westerly gales. A weak ridge moves over southern England at T+168 with WSW'lies for all. GEM: http://meteocentre.com/models/glb00_120.html The Canadian run shows strong westerlies for all due to complex low pressure to the north and NW. JMA: http://217.160.75.104/pics/Rjma1201.gif A mixture of westerlies, NW'lies and northerlies covers the UK with a ridge over Ireland and Wales. Winds become strong westerlies at T+144 with low pressure deepening to the NW. NOGAPS: http://217.160.75.104/pics/ngp10.prp.120.europeg.gif Low pressure is centred to the SW of Ireland with a trough over northern England. Winds are SW'lies across England and Wales, southerly over Northern Ireland and SE'ly over Scotland. |
