Here is a summary of the latest NWP output for 12z on Wednesday. Issued
0553z, 5/11/05. The models continue to show a zonal setup for the latter half of next week with wind and rain for all. ECMWF: http://217.160.75.104/pics/Recm1201.gif ECM shows a weak ridge over the UK with westerlies for most. By T+144 the winds become SW'lies and WSW'lies as the UK becomes sandwiched between a low to the north and a high to the south. A secondary low deepens to the north of Scotland at T+168 and a trough crosses Ireland. This leads to strong or gale force WSW'lies and SW'lies over the UK. MetO: http://217.160.75.104/pics/Rukm1201.gif MetO shows strong to gale force SW'lies, much as with the ECM at T+144. A large high lies to the SW and by T+144 it moves ENE'wards over France, leaving the UK under SW'lies. GFS: http://217.160.75.104/pics/Rtavn1201.gif England and Wales lie under a ridge, with SW'lies elsewhere. The ridge moves eastwards at T+144, leaving the whole of the UK under SW'lies. The winds become SSW'lies and southerlies at T+168 as a trough approaches Ireland. GEM: http://217.160.75.104/pics/Rgem1201.gif Unavailable today. GME/DWD: http://www.wetter.com/home/img/sat/g...050000_120.gif A trough covers the UK with WSW'lies for most. The trough moves away to the east at T+144, with a weak ridge over the UK instead. Winds are westerlies for all. JMA: http://217.160.75.104/pics/Rjma1201.gif The Japanese run shows a weak ridge and westerlies for all. Strong SW'lies cover the UK at T+144 and T+168 as a high moves ENE'wards over France and Switzerland. NOGAPS: http://217.160.75.104/pics/Rngp1201.gif NOGAPS WSW'lies associated with a weak trough over the UK. By T+144 the winds become SW'lies as pressure builds to the south. KMA: http://www.kma.go.kr/kma03/gif/g21nh_smsr_120.gif The Korean model shows strong WSW'lies due to a low to the north and a high to the south. MM5 snow forecast: http://rain.mmm.ucar.edu/mm5/plots/n...snoc.hr120.gif No snow is forecast to lie over the UK at T+120. |
