Here is a summary of the latest NWP output for noon on Tuesday. Issued
0510z, 20 October 2006. The outlook is generally unsettled with low pressure close to the UK. However, there are signs that for a day or two in a week's time high pressure will cross the UK. At this time of the year, it could well lead to the first widespread frosts - but as ever, more runs are needed. ECMWF: http://85.214.49.20/pics/Recm1201.gif The UK lies under low pressure, with centres over southern Scotland and to the SW of the UK. Winds are SSW'lies over much of England and Wales with northerlies or NW'lies elsewhere. NW'lies affect all areas at T+144 as the low to the SW moves swiftly NE'wards. By T+168 a ridge builds from the Azores High, leading to a mixture of westerlies and northerlies. MetO: http://85.214.49.20/pics/Rukm1201.gif The MetO run shows NW'lies for Scotland and NE'lies for nOrthern Ireland, with a weak ridge to the west. England and Wales lie under a col, but by T+144 low pressure moves over Biscay and NE'lies affect the UK as a result. GFS: http://expert.weatheronline.co.uk/pslv_frame.htm A col covers much of the UK, with easterlies over southern England and Wales from a low to the south. The winds become NE'lies at T+144 as a trough extends over the Low Countries. Winds fall light at T+168 as a transitory ridge covers the UK. GEM: http://meteocentre.com/models/glb00_120.html Unavailable at time of issue. JMA: http://85.214.49.20/pics/Rjma1201.gif The Japanese run shows a col over England and Wales with northerlies elsewhere. NOGAPS: http://85.214.49.20/pics/Rngp1201.gif Low pressure is centred over the North Sea, leading to strong northerlies for Scotland and Northern Ireland with westerlies elsewhere. |
